DIY zxv10 h108l modem repair

According to statistics, this defect of ZTE modems from Ukrtelecom is quite common. Its manifestations are as follows: the modem indicators signal full operability and the presence of all necessary connections, but Internet access is impossible, and any attempts to check or change the modem settings via the WEB interface are unsuccessful, since the modem's IP address is not available and ping to it, of course , does not pass.

The most common cause of this defect is a malfunction of electrolytic capacitors, which is mentioned in the materials posted on the Network. Unfortunately, those who had to eliminate the aforementioned malfunction in their reports somewhat subjectivize the diagnostic process, indicating a malfunction of specific capacitors (most often installed at the outputs of the + 5V and + 3.3V converters and having a significant capacitance of 470 μF). In fact, practice shows that failure of any of the modem's capacitors is equally probable: one should take into account the operating life of the modem, the specifics of its mode of operation, as well as the manufacturing quality of capacitors, the very origin of which leads to their failure literally after several years of intensive work.

Separately, you should touch upon the issue of disassembling the case of the modem. If you have not previously encountered this operation, I strongly recommend that you first read about its correct implementation on the Internet, since the design features of the case, frankly, do not dispose of it and some skill is required to successfully complete this procedure.

I would like to note that the modem case consists of two halves, and it is the front one that is removable (having a smaller thickness). After unscrewing the two screws in the lower part of the case, it is necessary to partially separate its halves in the direction from bottom to top. The upper part of the front panel has two latches that fit into the windows on the rear of the case (see figure).

ADSL modem ZTE - ZXV10 H108L

In conclusion, I would like to note that the described defect is typical not only for modems, but also for other network equipment with potentially low maintainability. In particular, a significant number of periodic or complete failures of routers (routers) and switches (switches) have been successfully eliminated precisely by carefully checking and replacing faulty electrolytic capacitors in the supply voltage filtering circuits.

If there is a problem with lan on the ZXV10H108L router, when the computer cannot get an ip address, identification takes a long time, and the received packets are equal to 0, although the lan LED is on, do not rush to throw out the router or carry it for repair, which may turn out to be not as complicated as it seems and make it you can do it yourself.

In many cases, to restore operability, it is enough to change the capacitors in the Lan piping in the router, these are C102 and C76 (nominal 47mkf / 25v).

The red arrows in the photo below show the location of the capacitors.

It is advisable to replace it with 100mkf / 25v, after which the modem started working.

Miroslav, there is no separate wifi chip in the 741 TP-Link, both wi-fi and switch, everything is implemented in one processor chip. If wi-fi is turned on in the settings in the web panel, and the LED is off and there is no wi-fi signal, most likely the problem is in the processor itself. It is unprofitable to change it. Alternatively, albeit unlikely, the ART section of the flash is corrupted. In this case, flashing fullflash on the programmer with soldering of the microcircuit will help.

There, the problem is that under one of the capacitors, a voltage regulator is installed on the board and it heats up by itself, and since the board is vertical, the capacitor heats up.Therefore, all owners of these routers have the same problems. Only those who have a router working all the time have problems earlier. Well, it also depends on the temperature in the room. And those who thought of installing a router on a windowsill, under the rays of the sun, a year later began to change routers to another.

Somehow it did not help from the first capacitor, I had to sort it out until I found the right one. But I found the article right away and to the point, thanks!

If all the fields on this tab are inactive, this will indicate that this is not a problem in the modem, but in the above-mentioned Kerovaniy modem service as a result of another attempt by Ukrtelecom to fix everything.

I re-soldered these banks, the ports are working)
I also have the same router, so when it is turned on, it blinks for everyone, and then only power lights up and everything, what could be the reason?

I will say this to me that they told me that WLANs are on on this router (modems) and this leads to the loss of the Internet

Author, thanks!
I fixed the modem in 15 minutes according to your instructions!

Thanks to the author, replacing two conductors revived the LAN ports!

Replacing the top air conditioner on the little one at 100mkFx16V. Before the cym oscillograph, adjusting the springs on all air ducts and adding a pulsation of 300 mV peak-peak to the upper air duct. LAN come alive! Dyakuyu author.

Dyakuyu, to the author, in the same way he zapratsyuvav. 100 uf 25v.

Cool! Thanks ! Working! 100μF 25V

Thanks for the advice.
Only in the scrap was to stomp for new condenders (rain on the street), a pair of 470/25 dropped from a dead vidyashka and the modem again saw the LAN ports. Well, I also rolled firmware 25 just in case.

many thanks to the author.
changed, only it was 16v 47mf replaced with 100mf 16v
the modem came to life

Thanks to the author! I replaced the capacitors with 100mkf 25v, the patient came to life!

The article is super-useful, my modem also “made me nervous”, read the article, opened the “villain”, dropped the conductors - they turned out to be 47mkf16V, I replaced them with 47mkf25V (well, just such were the old ones) - and a miracle, a modem earned like a beast. On occasion, I will change to 100mkf. By the way, for the inexperienced I changed capacitors - the more the voltage (within reason), the longer they will last, you can change it by 50V. And yet, these condensers warm up a little, like everyone else in their area, up to 40-45 degrees, for some reason I won't say, I don't know, that's why it can be seen "flowing", therefore the conclusion is that the voltage above 16V is definitely better. To the author of RESPECT and UVAZHUHA.

And I have such a problemma only power is on and run blinks. Lan does not light up wifi, no, what could be C102 and C76 changed.

On the radio market in your city.

Can you please tell me where to get the capacitor?

I did everything as written in this article, and a miracle ... the modem came to life, from the beginning I did not even believe it, but the LAN ports began to work when it replaced it with 100mkf / 25v.
Respect and respect to the author.

Soldered, the modem came to life. though only LAN1 remained working

Change, you can put both 16V (if there were 16v) ​​and 25V, more is just better, there is nothing to worry about, the conductors will simply last longer.

A question to the author of the article. The ZXV10H108L modem with symptoms: LAN1 is detected for a long time, packets go to the modem, rarely back. Lan2-4 is generally dull. Wi-Fi works seamlessly. I decided to open and change the condensers - but that's bad luck, the denominations C76 and C102 indicated by the author differ from those soldered to my board (soldered 16V 47mf). It's kind of dumb to put 25-volt cans in their place. What to do?

question on zne 108l. the same garbage with me. Lan disappeared into the interface comes tight, and then only until login. It cannot go on. But on wi-fay everything is normal. replaced all Conder. put polymer. did not give any sense. But I noticed that at counterpoint 10 instead of 5v, only 1.45v. I applied 5v to the point wai mikruha, it became very hot. Until the dead end.

how to open (open, disassemble) a ZTE ZXV10H108L modem (ukrtelecom):
modem case with two screws (the second one under the guarantee sticker) and four latches. latches, if you look at the photo of the board in the article:
below - one near the power socket in the area of ​​the L22 inscription, the second - at the left edge of the DSL line socket. with a thin knife along the end, with an effort in these places (a knife in the gap between the transparent insert and the thin half of the body).
from above - to the left in the area of ​​the dash drawn with a marker. on the right - in the area of ​​the unsoldered place under HL1. I took these latches with a thick sewing needle through the holes in the end.
Shl at the same time replaced the swollen C13 and C14 (in any case, they had no effect on work before replacement). 470mkf10v

Thanks a lot. I took the advice. The friend was very pleased. The modem works like new. I will add that it is very good to shunt these containers with 0.1 microfarad ceramics.

The router (modem) ZTE ZXV10 H108L was very actively used by Ukrtelecom at one time. After a while, these modems began to fail. The problem lies in the impossibility to enter the modem settings (), the modem itself does not ping through the LAN, although the lan LED is on. At the same time, WiFi works in normal mode. I will tell you how to repair a ZTE ZXV10 H108L modem in this video. All you need to repair is to replace 2 capacitors in the Lan harness in the router, these are C102 and C76. The nominal capacitors are 47mkF and 25V. We watch and subscribe to the channel!

The router works but there is no internet connection, it is also impossible to enter the web interface (192.168.1.1). Solution.

Good day. In this article I will share how to configure a ZTE ZXV10 H108L modem with a router connected to a DHCP provider.

Attention! The author of this note has nothing to do with Ukrtelecom, and does not solve problems with the Internet. It simply feeds on helping users through their experiences. If something does not work for you and cannot be repaired on your own, then simply contact the company's technical support service - 0-800-506-800

It so happened that my notes about the CSO and CSO Start service are one of the most commented on, and most of the reviews are negative. I would like to comment on the current situation (I warn you right away - this is just my point of view, yours may differ from it, this is quite normal).

I think it's worth separating the quality of the Internet from the level of service. Service in Ukrtelecom is lame, I will not hide it. Therefore, it is better to avoid it and try to take some actions yourself, namely, check all your data before connecting, make sure that you do not have a blocker and noises on the line (in the handset). If problems arose in the process of using the service through no fault of yours (no one is insured from this, this happens even with the most expensive providers), then you should seek help on an unofficial forum , where the real representatives of the technical department of the provider hang out, who know their business and will help (if you do not be rude and demand help from them immediately).

Attention! This guide discusses how to configure the modem in router mode. Since only the modem is configured, this guide will work for all platforms - Windows, Linux, Mac.

Not so long ago I set up a saber modem for a friend for use with the service WOW! (in his case it was a package WOW! Start, which allows you to get the Internet without concluding a contract). Since some difficulties arose during the setup process (big for my friend and a little less for me), I decided to describe the setup process in a blog, maybe it will be useful to someone).

So let's get started. We assume that you have all the data for connection, DSL is raised for your line on the side of Ukrtelecom (if this is not the case, then you need to call the support service and communicate with them).

The first thing to do is to connect the modem to the computer via an Ethernet cable (I think this connection is the most optimal, since it does not require additional drivers to be installed). If there is no network card (and most modern computers have one), then you need to either purchase it, or connect the modem via USB and install the drivers that come with it. After installation, a network interface will appear in the system, through which the modem will work.

One more thing - we will set up the Internet in router mode, since it is more convenient - to connect, you just need to turn on the modem, no additional actions on the computer are needed. This also gives additional flexibility - if you want to connect several computers, you simply purchase a switch, plug the cables into it and the Internet is automatically raised on client machines without additional configuration. Another advantage of the router mode is that after reinstalling the operating system, you do not need to configure anything - all settings are in the modem, so the Internet will work immediately after connecting the cable.

After a short introductory lecture, let's start setting up - we will do it by hand through the web interface, without using the configuration program that comes with the modem. To do this, open your browser and go to 192.168.1.1... If the browser does not display a page with a password request, then restart your modem (there is such a hole in the back, signed by RESET, put something thin there and hold it for a while until the POWER lamp blinks), maybe someone set it up and changed it Default IP address. If this did not help, then go to the TCP / IP settings of your network card (on the desktop find the "Network Neighborhood" icon, right-click, select properties, find your local network connection, right-click on it, again “Properties.” Then in the window that opens, look for the item “Internet Protocol (TCP / IP)”, select it and click the “Properties” button). The "Obtain an IP-address automatically" item should be active in the settings. If it is not, then select this item and press the OK button. Then again open the browser and go to the page 192.168.1.1.

On this page, you will be asked to enter a username and password - enter the standard admin (if it does not work and you have not changed the password, then just restart the modem, as described above). Then you get to the page for selecting the setting mode,

Open a port for torrenting, for example, on a ZTE ZXV10 H108L modem

In the newest versions of torrents, access can be made automatically in the torrent itself.

1. uTorrent now works mainly over UDP, so it is worth opening the desired port for both protocols (TCP / UDP).
2. WAN Host Start IP Address
WAN Host End IP Address
you don't need to prescribe anything
3. WAN connection - select a connection (Internet by default) with VPI / VCI 1/32 parameters - this is Internet. Connecting to 1/33 is for IPTV.
4. Look at the port in the settings of the torrent client and write in all 4 cells where the name contains the word Port
5. Find out the exact IP of the computer on which the torrent is installed (if everything is automatic, then by opening the window of the local network connection status, go to the Support tab and see the address) or register the address manually and enter this IP address in the Lan Host IP Address field
6. Press the Add button and reboot the modem.
Everything should work.

If the settings are not saved after the reboot, then the modem may return to its original state by the provider's CPE function (the telecom has such a feature - remote modem configuration). This feature still works unpredictably, it is best then to call technical support and ask to disable CPE on your account.

Today I want to tell you how to configure a client-server using a ZTE ZXV10 H108L modem via DHCP. You need to be able to do this, since in the near future Ukrtelecom plans to abandon the connection via PPPoE and switch to DHCP.

What is DHCP and what it is for, read the helpful and informative Wikipedia article.

And we get down to business.

In order for the modem to work in the router mode and the connection is made via DHCP, the first thing we need to do is connect the modem to the computer according to the instructions and open the browser.

• In the address bar you need to enter the IP-address of the modem and press "Enter / OK"

• In the next window, enter your username and password. By default it is: Admin, Admin.
  
• And click Login. Next, the modem settings window will open, at the top menu, go to the "Network" tab and open the "WAN Connection" section.
• All PPPoE settings from VPI / VCI 1/32 must be deleted using the Delete button.

Next, go directly to configuring the modem and make the following changes in the settings window:

• On the "Connection Name" tab, select "DHCP" from the list.
  
• On the "New Connection Name" tab, register "DHCP" or any other name.
• We put a tick in front of "Enable NAT" and on the VPI and VCI tabs, write the value 1/40.

This completes the DHCP settings for the ZTE ZXV10 H108L modem to work in router mode.

Now, without changing anything, press the create button.

Now we need to restart the modem. We do this:

1. In the top menu, select the "Administrator" section.
2. Go to the "System Management" tab.
3. In the configuration window, click the Reboot button.

After rebooting (takes about 3 minutes) the modem is ready for use.

The router (modem) ZTE ZXV10 H108L was very actively used by Ukrtelecom at one time. After a while, these modems.

The router works but there is no internet connection, it is also impossible to enter the web interface (192.168.1.1). Solution.

Hello everyone! In this video, I repair the ADLS modem ZTE ZXDSL 831CII, which works strangely. Weirdness .

Firmware for Router Zxv10h108l 25.

We make WIFI output from the internal antenna to the external one, or how to make it so that you can connect an external one.

Very often the reason for the failure of a router is a breakdown of the power supply. The video shows in detail.

We connect the Cisco WRT54G2 V1 router via the UART interface.

For smart people! All capacitors have been changed, both swollen and not swollen. I showed exactly which capacitors to change if the LAN ports do not work, where they are on the board.

Woe to the repairman - in front of his nose, he does not see two bloated condenders! How can you pass by !?

* Tell me if it is possible to connect an external antenna to such a modem？ *

There would be C14 and C13 to change for a start - they were already blown out of joy

missed two swollen containers right in front of my nose

Yes, the renovation is clearly not professional. Forgive the person, the main thing at the moment has achieved the result. In general, people correctly noticed about swollen capacitors. I will say more, those who have changed only those offered in the video will soon change again. I'll tell you why. The two swollen capacitors are nothing more than filtration on the supply of the secondary network. The source of the problem is not excluded. It is advisable to change them to low impedance capacitors. For those who do not know, they are distinguished by a yellow stripe on the minus side. We ask in stores or look on the Internet.Further, my c11 is swollen, it is also mandatory to change it. In general, I advise you to change the whole group, c7, c105; c13, c14; c11; and last but not least c76, c102. In this variation, you won't have to look there for a very long time. It will rather become obsolete. For non-professionals, we bring it to a professional, or, on our own, we must change all the bloated and additionally c76, c102. I advise you to do only those who are more or less friends with a soldering iron. The board is multi-layered, the chances of killing it are high enough. Professionals will immediately check the capacity of all capacitors with the device.

I will also add that he worked until the breakdown of the year 3. He worked under a slate roof. in winter -20 in summer it was warming up in the bathhouse. He left the side gradually. At first, the Internet regularly disappeared at night and appeared at 10 o'clock. this behavior lasted two weeks - then it completely disappeared. There was no specialist in Ukrtelecom who could help.

thanks for the help) the symptoms are exactly the same! replaced two capacitors as in the video. The router is working! In fact, the native capacitors are 47mkF at 16 V. but it does not matter. Those who will change - drink carefully! because I almost ripped off the track (it's better to watch the video on how to properly solder something with a home soldering iron)

Slapstick, because of you I cannot snap off the upper latches, so now I have to break it nah.

Well, tell me how to open the lid with latches, you already have experience

+ Territory of men so heh would say in the video that the latches there are tricky, over the course of my life tlinks have hidden 3 hundreds of them, but at the first there were a couple of latches that broke later like seeds and not a single latch was broken and there are no signs of opening at all, but here these latches are so horny made one had to donate. And no where not a word that to anything, not a single disassembly video, most likely, just like me, they suffer and are silent, for the first time such a cocoa got into the hands of a simple one, in general, sadness, well, of course, I cannot disagree what kind of device is this and the approach to it , after the repair, even without a case on the wall, it weighs and so collects dust, I was shocked by what I saw. It just bombed in this situation. And believe me, yours won't become and won't be like that, well, unless you start doing robotics. )

If your hands grow from the place where you are sitting, I am not an assistant to you.

a way to fix a router we take a stick one hit two hit and the router is in a landfill

This is not a professional approach to renovation. First, you need to replace the swollen capacitors first. Secondly, you need to use an ERS meter to find all capacitors that have an increased EPV (more than 1 Ohm). After that, as a rule, the router works for many years.

Sorry, but I do not have a home workshop and do not repair routers. I showed you a quick and easy way to repair.

Tell me what varistors are on this modem. s157 and s156. cracked read nothing.

It seems to me or are the two middle capacitors swollen?

yes, you can immediately see that swollen

We will change it as needed, and I don’t use this modem either)

+ Alex Flinwood doesn't seem like the author will soon feel their bloating

+ Alex Flinwood Oh, no. The modem works fine after replacement, then it did not bother with the replacement)
