I do not think about ISP
Most probably something in the router
and it is not a software bug.
My has around 10000 errors on nas0 interface (command ifconfig)
If I find the fault I will publish info here

I have spent a lot of time trying to make working properly my routers (both Lantiq based).
Seems to me Lantiq platform is very sensitive to pulsed interference from power supply.

Stability a little improved when i used PSU Mean Well LRS-35-12. But some kind of pulsed interference require a grounding of this PSU.
Also DC Voltage is important. Too high over 12.6V will produce more errors, Too law (less then 12.2v) - and LAN is not working properly.

At the moment I did not get work of the router perfect on both stock and LEDE firmware
Here is statistic after 2 days of work with 1 DSL reconnect:

As you can see a lot of errors on DSL interface and some dropped packets on the LAN.

PS this is the last post here. I will move to LEDE forum

Thanks Snakus could you to let me know the thread name in LEDE forum? Did you keep you name?

FYI, I don't get any error, drop, overrun, etc for few days (more than 12 GiB TX/RX), I'd guess you have an hardware issue, no?

I am experiencing strange racing issues in the latest LEDE versions (right now r2523).
the wifi doesnt usually come up after reboot and requires 'wifi up' command (the log shows wifi command gets issued before wifi driver gets initialized)
nas0 interface also usually(sometimes it does) doesn't come up on it's own and requires manually restarting br2684ctl service.

Hi all,
I have a td 8970 with this firmware version:
0.6.0 2.1 v000c.0 Build 130415 Rel.34164n
(never updated since I bought it many years ago).
Can I install openwrt chaos calmer or some newer lede compiled versions from web interface?
If so, do I have to use the sysupgrade file or other kind of firmware?
Thanks in advance

No, you cant. You can install Openwrt/Lede firmware using wiring or using clip-in programmer. We are doing this all the time for 20 euros. Later upgrades via web after then are possible.

Is there a difference between OpenWRT and LEDE (which is a fork from OpenWRT)? What's recommended for the TD-W8970?

I have a w8970 with this firmware version:
0.6.0 2.1 v000c.0 Build 130415 Rel.34164n

I install openwrt 15.05 from web interface !
I follow this guide:
wiki.openwrt.org/toh/tp-link/td-w8970
Table of contents:
Web Interface Hack (Install OpenWrt without opening the case)

How did you flash the image itself, was it by following the steps here? :

where is the problem?

Hello guys, I'm new in this forum, I think my router is bricked.
I've followed all the steps provided by s7mx1 and at the last steps when I used these two commands :

cat /var/usbdisk/sda1/td-w8970/openwrt-lantiq-xrx200-TDW8970-sysupgrade.image > /dev/mtdblock1
cat /var/usbdisk/sda1/td-w8970/openwrt-lantiq-xrx200-TDW8970-sysupgrade-1.image > /dev/mtdblock2

I got two different errors, for the first command I got "no such space left on device" and the second command gave different error "there is no such directory" or something like that ( I can't remember it exactly )

What should I do ? sorry for being noob, I looked at Debricking page and I couldn't find my exact problem. I guess there is something wrong with mtdblock2.
After my router rebooted, only power light is on and the rest of them are off.
----
edit: I think I've found the source of the problem and that's the dd, that was the first time I tried to use dd and I downloaded it from chrysocome.net and when I used this command for input, I got the samething for output, appreantly that's the problem.

dd if=openwrt-lantiq-xrx200-TDW8970-sysupgrade.image bs=1310720 skip=1 of=openwrt-lantiq-xrx200-TDW8970-sysupgrade-1.image

Anyway I screwed up, Guys what should I do ?

Well, seems you erased oem kernel partition and end up with broken openwrt kernel. We can see that opewrt kernel has size: openwrt-15.05.1-lantiq-xrx200-TDW8970-uImage    1599375 bytes but in your logs only 1310720 bytes of it has been written.
All you have to do is to open case, connect UART TTL-serial adapter, read carefuly article here: https://wiki.openwrt.org/toh/tp-link/td-w8970 and start to install openwrt via serial/tftp method.

Thanks for information, I think all the problem comes from DD, I used it on windows and I don't have any knowledge of using that, any command I use it doesn't work and I get same command in output. Is there something wrong with DD ? or I don't know anything of it ?

I've bought CH340G Serial Converter from Aliexpress and it's on the way. I got some pins ( 6pin, 8pin, 10pin),
Can you see if I got the right item ? I have put the links down below .

aliexpress.c o m/item/1PCS-CH340G-Serial-Converter-USB-2-0-To-TTL-6PIN-Module-for-PRO-mini-Instead-of/32309334168.html

Also I found way on the Internet, about using "TFTPD32" software and holding reset button for 4-5 sec and meanwhile turning on router, it will try to get the firmware automatically but I couldn't make it and after a few hours of trying it didn't work, the problem was with TFTP server address, I couldn't find it and also only power link and LAN is up, the rest of the lights are off.

About using serial connector, What part did you mean I need to follow ? Is it the right one ?

Thanks in advance .

You are right that command is wrong.
I uploaded screenshot of DD, whenever I enter any command it's like that,Actually I copied that command from s7mx1 post.

I've successfully flashed OpeWrt on this router!

As I backed-up the mtd partitions of the OEM TP-Link firmware, I would like to experiment the "revert back procedure"...

Which steps I have to follow to flash the original firmware?

Thanks for your help!

I forgot to mention that I have no serial access (at the moment); I've installed OpenWrt via telnet.

What I try to accomplish is re-install original firmware without serial access (just for testing purpose and to enrich the wiki!)

I imaging I could simply write back the mtd partitions and reboot, but I have no idea if I could simply do that or not.

Thanks folks

Given you don't have serial access, would you mind outlining the steps you took to flash it? I followed the recipe on the wiki, as I described here:

https://forum.openwrt.org/viewtopic.php … 29#p343429

and the router didn't come back after the reflash/reboot.

I've just followed this steps from the wiki page of the TP-Link TD-W9980; the only part i've skipped is "Install DSL drivers".

If you need more in-deep explanation, just ask me

Followed the same instructions on another TD-8970 (again another version 1.2) and it succeeded using identical commands, so I suspect there was a minor revision difference either in hardware or firmware that causes the upgrade to either be successful or not based on initial state of the router.

Hi folks I need help. I have V1.0 hardware and both web hack (via SSID injection) and the java tool configuration hack failed. I managed to solder serial pins and now I have serial access. But I stopped at the very first instruction to "Download the openwrt-lantiq-xrx200-TDW8970-uImage-initramfs image from wherever you can find it"

Does anybody have this or another suitable file?

Have you tried the installation direct to flash as explained in the WIKI?

Nope, but I followed instructions from post nr.319 and that worked. Now I have LEDE up and running.

I have installed OpenWrt on my TP-Link TD-W8970 following the instructions in the wiki for TD-W9980: Web Interface Hack (Install openWRT without opening the case). Did not install DSL drivers because I do not have internet for this router and only want to use its Wifi to connect to my local network. Everything seems to be working fine, except that changes I make in the web interface, e.g change root password or enable Wifi, is not remebered/saved after reboot. It seems to me (newbie) as if changes remain only in volatile memory. How to find out what is going on, please help.

I have a 8970 that doesn't boot , only power lights up and wifi (faintly) .Usb -ttl method can't find connection. Is there an image to flash with usb eeprom programmer to revive ? Thanks

I have one of these routers running LEDE with SQM (cake/codel) turned on (not significant in itself - but mentioned because of associated circumnstances). I also have collectd so I can collect cpu/mem stats. If I saturate the connection by triggering lots of downloads everything works fine for sometime.

However at some point the router will drop all connections (all TCP connections - the ADSL2 connection itself stays up fine), this is associated with a brief and sudden spike in CPU. Nothing else is happening on the router at the time.  I should point out that the ADSL2 is connecting at around 20Mb/s so it's not as if I'm running into the internal bandwidth limit.
