Yeah right but nobody will write you or see your post i wrote 2 days before folowing link https://forum.openwrt.org/viewtopic.php?id=44398 but nobody respond.
Oh god, stop it! 340+ posts. Please create a relevant new post.
Maybe nobody has any idea how to help?
Yeah i was thinking about....
Maybe nobody has any idea how to help?
802.11n of PS VITA is not working on OpenWrt 12.09, it freezes downloading files... i had to set up 802.11g on my TL-WR841N in order PS VITA to work, but is there any other solution?
I added the USB in 841n v8.3. All works. Changed the file mach-tl-wr841n-v8.c by adding the lines
static void __init tl_wr841n_v8_setup(void) { tl_ap123_setup(); ath79_register_leds_gpio(-1, ARRAY_SIZE(tl_wr841n_v8_leds_gpio) - 1, tl_wr841n_v8_leds_gpio); ath79_register_gpio_keys_polled(1, TL_WR841NV8_KEYS_POLL_INTERVAL, ARRAY_SIZE(tl_wr841n_v8_gpio_keys), tl_wr841n_v8_gpio_keys); /* ADD USB */ gpio_request_one(TL_MR3420V2_GPIO_USB_POWER, GPIOF_OUT_INIT_HIGH | GPIOF_EXPORT_DIR_FIXED, "USB power"); ath79_register_usb(); /* END ADD */ }
sorry for the Google translate
Great mod
I have a question of this kind, those pins External, you tried to connect without drilling out the chip?
P.S.
It would be a good idea to write this mod on the Wiki.
, you tried to connect without drilling out the chip?
filed off part of the chip

Hi !
Can you give us more informations about this mod ?
Per example, what pins ..

Hi m8s
Take a look at my usb mod for v8
http://postimg.org/image/ptbftulqf/
I successfully connected to the D+ D- pins without drilling out the chip, and also added 7805 and some capacitors to get supply for USB.
And of course I changed file mach-tl-wr841n-v8 and build image from 12.09 sources.
However, now I have some problems with the installation of packages from the repository.
Some packages can not be installed because of issue with dependencies.
Collected errors:
* satisfy_dependencies_for: Cannot satisfy the following dependencies for openvpn:
* kernel (= 3.3.8-1-d6597ebf6203328d3519ea3c3371a493) *
* opkg_install_cmd: Cannot install package openvpn.
Does anyone know how to build an image with castomized mach-tl-wr841n-v8, to be able to install packages from 12.09 repository?

Hi,
Thank you !
No, ask here : https://forum.openwrt.org/viewforum.php?id=2

Did You connected wires to the top side of chip pins, as showed in my post ?

I think top side is the same as the pins near pcb.
But really I do not see where D+ wire soldered. To the top side or on the pcb pin. Because I did not completely wash off resin.
I dont understand because D- is not soldered on the PCB..
How do you know that your D- (not on IC) is really the D- pin ?!

Hello guys. I have a problem with my router. I tryed to upgrade the firmware from TL-WR841N_V8_121101 to TL-WR841N_V8_130506 and i don't know what happend and now router led's turn on and off every 4-5 seconds .. only the power led it's allways ON. I search this thread a little and i found a post by undermonster at page 4. But when i'm at this point
2) Turn Router ON. Press the WPS/Reset button many times.
3) Wait for LED under gear icon to flash rapidly.
Your router is in Recovery Mode now.it doesn't do anything.
At the point
2) Open CMD/Terminal
3) Type: ping 192.168.1.1it say's
Destination host unreachable
Can somebody gives me some advices ? or what i can do to it :-/

This is exactly what happens when you forget to strip the uboot and flashing from openwrt the original firmware 
Your router is bricked now, because it does not have tftp recovery mode. If you have it under warranty, get it replaced (just don't tell them about openwrt!). If it's not under warranty, you will have to open it and use serial console to recover it.
No, it's not under warranty... damn .. And how i can do with " serial console " ? I found a lots of threads about it . Can u show me which one have you tried ? or something like that and it works 101% ? 
Thank you very much.
The serial console is nice, it works fine, just don't worry and try it, now it is as good as completly dead one, but there's very high chance you can rescue him 
What is not nice, that you need to buy cable, 10k resistor, open the device and solder, so it is not very user friendly, but there are hundred success stories. If you never made that, very basic steps are for example here: https://forum.openwrt.org/viewtopic.php?id=42331 (note, that it is a different model)
Never debricked wr841nd myself with cable, all wr841ns I have are still under warranty, but had success with wr741n for the very first time I tried it. Be sure to read instructions for wr841nd, because this model needs a pullup resistor, unlike wr741n, which is a bit easier to connect.
Can some use the HT40 channel without Wifi drops? If i use the HT40 mode the clients get pretty often disconnected :-/. I have a 8.1 with AA stable.
Need some help with TL-WR841nd v8.1
Because of the Wifi drops I want to flash back stock firmware as described at WIKI page. But I can't find any none boot stock firmware for TL-WR841nd v8.
For TL-WR841n v8 n there is stock firmware without boot as described earlier during this discussion. But I am not sure if its save to flash n stock firmware to nd device.
Instead of stock firmware I would feel fine to flash DD-WRT first and then flash DD-WRT's webrevert file. But here aswell. Which flash file would be save to flash with telnet?
n or nd is the same...
Yes, they have the same firmware, I use this firmware with uboot stripped (be sure to download using orange button premium download, but it is free):
md5: bf4f9e637bf670f5262649d534ce7800 wr841nv8_en_3_13_27_up_noboot-120802-openwrt-back-to-factory.bin
http://bayfiles.net/file/RORx/jWo1Wm/wr841nv8_en_3_13_27_up_noboot-120802-openwrt-back-to-factory.binThis is the latest firmware:
md5: 488554f4fc5c108e9d4b5b5f528ddb69 wr841nv8_en_3_13_33_up_noboot-130506-openwrt-back-to-factory.bin
http://bayfiles.net/file/ROTn/72HsZf/wr841nv8_en_3_13_33_up_noboot-130506-openwrt-back-to-factory.binYou can also right click on the bayfiles "premium download" button and copy link address, then download using wget directly to your router, if you are not going to upgrade from web gui. Be sure to check md5!

Thanks. Reverting back to stock firmware worked like a charme.
Could flash it even through OpenWRT's Webinterface.
And of course I changed file mach-tl-wr841n-v8 and build image from 12.09 sources.
Share your firmware image please.
and mach-tl-wr841n-v8.c
thak you.

successfully modified WR841N v8 too.
connected to the D+ D- , old usb car charger for 5v regulator.
can't compile USB support by your self. using mr3420-v2 image from trunk.

NEW FIRMWARE for TP-Link TL-WR841N/ND v8.x
OpenWRT Barrier Breaker @37754 (LuCI)
Here is a new OpenWRT build for TP-Link TL-WR841N/ND v8.2. It should work with v8.0 too, because they have the same hardware. Version is trunk r37754 (Barrier Breaker). This build includes:
LuCI (the web interface)
IPv6
upnp: miniupnpd
IT IS UNTESTED.
I am still running an older build without IPv6.
If you have the original factory firmware in your router, flash the file with "factory" in the filename. If you already have OpenWRT and only want to update, flash the file with "sysupgrade" in the filename. You can do that from the web interface in both cases. Extract the RAR archive before flashing! You have to flash the .bin files. Flashing the wrong file will likely brick your router, so be careful.
I hope this helps. Please report about problems or success, so I can edit this post accordingly.
