OpenWrt Attitude Adjustment 12.09-rc1 installed on TP-Link TL - WRT841N V8.3
I don't know who is the one who put so much hard work on this firmware but already 13 days this firmware working without any problem, and i also install P2P blocking software (freifunk-p2pblock) which is working awesome.

Thanks,

hi to all, I'm new on this forum and in the openwrt world...

I managed to figure out which file to install in my wr841nd v8, installed and now I'm trying to configure it as wireless repeater...

If I'm not wrong, I need to install luci-proto-relay and then.... I'm lost... I tryed to connect my AP to another router, but seems that something is wrong in my configuration.

someone can tell me which way to go? thanks

GREETINGS, sorry for my bad English, I have a router 841n v8, at the moment it is half a brick, I put openwrt firmware, I thought that it would by default pptp modules are connected, in general, decided to go back through the MTD, apparently threw the wrong firmware I received the following listing: "root @ OpenWrt tmp # mtd-r write / tmp/wr841nv8_ru_3_14_19_up_boot.bin firmware

After 2 min. diodes burned out as usual, there was even a standard net TP-LINK_35 *** on LAN does not issue DHCP IP-address, but on a Wi-FI connected by pin on the router, DHCP assigns address and I can Ping the gateway, it just all that I can. Prompt whether variants without desoldering episode throw him firmware, tried all that i can

Hi all,

i flashed my TL-WR841ND v8.1 via router web interface,
it works very well.

Thanks for all your splendid works.

Hello,

I am new to openwrt and have chosen after reading this thread to buy an 841ND (V8.1).
I flashed it with http://downloads.openwrt.org/attitude_a … actory.bin.
It works fine, got WAN and wireless (with strong encryption) running. Now I want to use it as a OpenVPN server. I tried to install openvpn. There is a problem: I got only very little Space on /, all space is in tmp! After the device booted the first time the filesystem looked like this:

root@OpenWrt:/rom/root# df -h
Filesystem                Size      Used Available Use% Mounted on
rootfs                    1.1M      1.1M     16.0K  99% /
/dev/root                 2.0M      2.0M         0 100% /rom/rom

overlayfs:/overlay        1.1M      1.1M     16.0K  99% /

I tried to mount

mount_root
switching to jffs2

After a reboot the filesystem looks like

root@OpenWrt:~# df -h
Filesystem                Size      Used Available Use% Mounted on

overlayfs:/overlay        1.1M      1.1M     16.0K  99% /

How can I get this fixed?

Thanks in advance

Hello,

I have a bit of an issue with my WR841N v 8.2 I have been trying to stream movies from my PC to my android through lan and wireless, but after everything I've tried I haven't been able to stream. I had no problems using the original firmware with no modifications what so ever.

PS: I am streaming through Windows Media Player 12.
I am running OpenWrt Attitude Adjustment 12.09-rc1.

Anticipated Thanks

c604213, you should use squashfs firmware, do not play with jffs, if you don't want to brick your router This is how looks mine:

root@OpenWrt:~# df
Filesystem           1K-blocks      Used Available Use% Mounted on
rootfs                    1600       256      1344  16% /

I don't have luci installed, but it shouldn't be that big, openvpn should fit.

Have you tried to reset the router using firstboot command?

Hello,

I have an 841ND v8.1 since last november.
After I bought it I had some problems with the stock firmware, so I flashed this firmware http://downloads.openwrt.org/attitude_a … actory.bin via the web UI.
Since last week the router would freeze one or two times a day (I had to unplug it to get it working again). Today I decided to flash the latest official firmware, wr841nv8_en_3_13_27_up_boot(121101).bin and now it's bricked.
After the flash I have read that I shouldn't have used the firmware with boot in the name.
I have connected a CA-42 cable to the serial pins, but the 'tpl' command does nothing and the output looks like this:
"[0C]

Here is the whole log: http://pastebin.com/AiRJ8Ji7

What can I do?

Your output has some strange characters, there's either something bad with your cable, or there's some hardware problem, like faulty ram, which might have been cause of your freezings. Maybe you could try with different baud rate, but I'm not expert with cables, since all of my routers are still in warranty.

The wiki says, you should use firmware without boot in name, when you want to go back, but it is not quite exactly, because tp-link does not use boot in name, even when the firmware does contain the boot loader. The only way to find correct firmware is to download them all, sort them by size, and use the smallest one. Usually the oldest firmware does not contain the boot loader, but I can't tell for sure, I have bricked 3 routers before I knew this, and later I have never had balls to try stock firmware again

Is it possible that you used too long wires or bad soldering?? If you try to connect tx with rx on the adapter, without the router, did you get a good echo typing lot of text in terminal??

Hello,

I think I mixed up RAM and Flash. I used the firstboot command (in failsafemode). Here after I had 950kb free memory wich looks similar to your post @nozombian.

root@OpenWrt:~# df
Filesystem           1K-blocks      Used Available Use% Mounted on

tmpfs                      512         0       512   0% /dev

overlayfs:/overlay        1152       232       920  20% /

I believe the 841ND is not capable of running openvpn and lucie, perhaps 4MB of flash aren't enough.

Thanks for help

Still not working:D

I have a v8 and I tried flashing the original firmware back but flashed the wrong one (the boot one) and now i'm stuck with a bricked wr841n v8. all the light are flashing except the power. I guess I will have to connect trough serial to it to flash it. How do i do that? Plz help. Thx

Is there any experts on this forum who get added support for 802.1q VLAN for Tp-Link WR841N?
Can someone provide this firmware?
Мay be for the current version of the firmware patch is needed?
I need tagged VLAN on the uplink interface for my multicast.

Look at my topic, may be you can help..

Hello, i have installed "openwrt-ar71xx-generic-tl-wr841n-v8-squashfs-factory" on this router but there are some problems on wifi, download and upload speed is considerable slower than the factory firmware, i only get max 20megabits down/up and sometimes i cant join the wifi. 

Can somebody please guide me how can i restore the original factory firmware on this?

It seems that Luci have a problem with switch on this router. I have internet and IPTV from my ISP in two VLANS and there is no wan port in "switch" section of LUCI (12-09-rc1 attidude ajustment on wr841nv8.1). So it`s impossible create interface like eth0.x where x is vlan tag.
But there is field "custom interface" in "interface" section where you choose physical interface, and I type there eth0.1214 (1214 is internet vlan of my ISP), so interface "eth0.1214" was created saccesfully, and my pppoe connection work now on this interface.

At the moment I use the following configuration.
Unfortunately for eth0.10 and can`t get settings with DHCP.

This means that VLAN 10 is not working.

Could someone plz help me, I would like to know the pinout for the 14-pin MIPS JTAG block for WR841N v8.

Thank you

Guys, is the failsafe recovery mode really working? I can get the led blinking fast by repeatedly pressing reset during boot, but I can't telnet to 192.168.1.1 in failsafe, i've got wr841nd V8.1 with trunk r35174. It's still in warranty, so I can't open it to look what's happening on the serial console. I made some changes and probably screwed something in config files, router seems to boot, but wifi is down and I can't ping to the latest known ip. Without failsafe I can't get in :-( Do you have some idea, what could be wrong/what I'm doing wrong?

edit: finally got to the failsafe, there is something strange about failsafe with this router, been in failsafe at least hundert times with my other routers, but here it took me about 10 tries to get the telnet working. It seems, that I need to wait a while before I start pressing the reset. Hmm...

(Last edited by nozombian on 23 Feb 2013, 15:54)

Why 'lan' is on 'eth0' instead 'eth1'? And wan is on 'eth1'?

It was set to that value by default router config.

Hi, sorry my don't know English, I used Google translate, I have a router 841n v8.3, my installation openwrt firmware (openwrt-ar71xx-generic-tl-wr841n-v8-squashfs-factory.bin) and setting up like http://www.youtube.com/watch?v=3rbsh2zxPnk
But the Local IP Address of my ADSL2 + Modem Wifi same Local IP Address a router (192.168.1.1)
Now I can not login to 192.168.1.1 of router.
Please guide me with the picture or video
Thanks.

ethernet cable.

Hello everyone,

i'm new here, i've some strange problem, tryed to search forums, but tracking, and gave me to results, i don't know maybe something with my router hw is wrong but i'm getting spamed in log:

Feb 26 18:01:57 OpenWrt kern.info kernel: [72658.880000] eth0: link up (100Mbps/Full duplex)
Feb 26 18:02:02 OpenWrt kern.info kernel: [72664.020000] eth0: tx timeout
Feb 26 18:02:02 OpenWrt kern.info kernel: [72664.020000] eth0: link down

After restart everything seems working ok, but after some time it's starts again, Wi-Fi works, local network works, but no internet connection when this message apears. I've TL-Link TL-WR841N v8.2 installed OpenWrt Attitude Adjustment 12.09-rc1 /LuCI 0.11 Branch (0.11+svn9425)

So maybe had similar problem to mine and can say how to fix it? Thank you. If you need aditional info say it i'll try go put it.
