what is the current firmware version? I don't suggest try TL-WR941ND, as it may damage the router.

Hi,

The same question here.
My avast antivirus noticed that my router is weak for hacker and that a firmware update can easily fix this problem
I checked for an upgrading file and found only the TL-WR941ND model instead of the TL-WR941N one.
TP-Link seems to consider these 2 models "equal" for the firmware upgrading...or somewhat similar (940N insteand of 941N) "
"Notes:

TL-WR940N(US)3.0 /
TL-WR941ND(US)6.0 "

Firmware version :3.9.7 Build 090821 Rel.38819n
Hardware version : WR941N v2/v3 00000000

I know it's not written 941N but does 940N means all the 940's serie ?

If not, where can I find a 941N firmware upgrade file to fix this security problem ?

Thank

If your model is TL-WR941N, you can try the firmware of TL-WR941ND.

Note:make sure the hardware version should be same. For example, your current hardware is V2/V3, you also need to update the V2/V3 firmware.

I think any WR94 version will do
