We need more info. Post settings and what you have done already.

Try WPA2 AES w/o no N speed.

The dd-wrt database shows firmware available for various versions of this model, however I'm seeing a number of posts that complain about settings not being preserved. Apparently there is an issue with a version of the router having a specific Intel chip. Is there a way to figure this out without opening the case of the router?

Also... I haven't seen anyone mention experiences with the dd-wrt firmware installed. Is it a notable improvement over the previous software? I had been using my WR941ND v.3 for about 1.5 years when I started having some problems with it. Basically, the router periodically drops connections. This tends to happen mostly under certain weather conditions: extreme heat, extreme cold, or heavy rain. Otherwise, it is a good router and can penetrate about 3 floors to provide a reasonable connection. I'm just wondering if the dd-wrt firmware will manage the hardware better and provide more reliable performance.

Thanks for any advice!

Hello DD-WRT fans and devs,
(1).I started to have problems with my TL-941ND - it randomly looses connection / more when there is a higher load /, seems like the DNS is stopping to work and even if i set it manually on the pc it still don't work, but i can ping ip's from the diagnostic tab of the router. I re-flashed it with stock a few times, but it does not fix it. As i can not afford right now to buy a new router i was thinking that i can save it somehow with DD-WRT, but mine is v3.2. Do you guys have any idea what can i do? Thank you.

(2).It's like 3 years now from the Intel S33 flash problem and as far as i understand OpenWRT can flash it, is there a fixed version for TL-941ND v3.2?

Hey brothers!

I have one EOC-2610 in AP mode. I want to expand it's signal with one TL-WR941ND (atheros radio).

The TL-WR941ND was set as Client Bridge (routed) as the follow:


image uploading


image host


It work fine, BUT when I add a Virtual Interface to host news connections like this...


hosting images

...the radio isn't broadcasting the Virtual SSID, and I can't ping the EOC-2610, even though the Wireless's status showing the TL-WR941ND connected to the EOC-2610.

Firmware: DD-WRT v24-sp2 (11/21/10) std
BUILD 15778
Router Model TP-Link TL-WR941ND v2/v3


I need help.

Tanks a lot!

It is still not confirmed that it is due to flash mfgr, it seems that none of the v3.2 owners are interested in providing a serial log so I will not bother any more trying to help them.
My v2 is working well so I don't have any problems..

There is probably none of them who has tried to update the software to Brainslayers latest build in order to see if flash can be written.


I have the TP-Link TL-WR941ND Ver 3.2 with Intel flash. After bricking it with the v24 preSP2 [beta] Build:15778 I flashed the original TP-Link image successfully via the Nokia CA-42 usb to serial cable.

So I can provide a boot log from the internal serial port. Smile (see attachments)

How did you do this exactly,I have done it with no success,I followed errertors Advices , but no chance to get Network connection,please can you write here your way?

You did everything right so far, but the TFTP-post you mentioned was missing to set an IP-address after booting the openwrt initramfs image, before executing the wget. The IP you set after uboot is not handed-over to the later booted openwrt. So you have to set an IP-Address once again with: ip addr add 192.168.1.10/24 dev eth0
Now you can go on with cd and wget ....

Hope that helps you to unbrick your 941 Wink

Good luck

i Set the Ip Adress , so far so good, but now i see Connection refused ,is it a problem with the Uimage? Can you sent ( attach) your Uimage here?

Connection refused has nothing to do with the UImage file, it is your server not allowing a connect.

The wget command is for transferring a file from a http server and I don't think your ftp server honours wget requests.

Your uimage is the same I used, because I recovered my 941 with the same instructions than you. Wink

Here the sha1sum of my 'openwrt-ar71xx-generic-tl-wr941nd-v3-initramfs-uImage.bin': 71bf518d1d2724bce3a463172f150a6757cc1a7a
or md5sum: b59ff82e80edcdcbe2e9c882fb4c187d

Here the commands I used:

setenv serverip 192.168.1.12; setenv ipaddr 192.168.1.250
tftp 0xa0800000 openwrt.bin; bootm 0xa0800000
<Enter>
ip addr add 192.168.1.250/24 dev eth0
cd tmp
wget http://192.168.1.12/941.bin
mtd write 941.bin firmware

LOM, does the serial log from the default TP-Link image or the other serial log from the openwrt help you to make dd-wrt working on the Intel flash based TL-WR941ND Ver 3.2 ?

I'm not working on it, I'm not developing dd-wrt. Wink
The problem is that dd-wrt needs a complete overhaul of the SPI flash driver, the serial log is not needed.

I don't understand why you even try to write the file, don't you read the error message?

You need to have a http server running which can serve the wget request.
