If you tried to reset it but it goes off constantly, I think there is a problem with wireless module, a hardware issue indeed.

Hello i have 2 devices and i have the same problem with both, wireless dropout is every day, after restart router and AP work correctly for one day.


--------------------------------

Region : Czech Republic

Model : TL-WR842ND

Hardware Version : V1

Firmware Version : 3.12.24 Build 130110 Rel.58124n

My settings proposition - LINK

*cant access web interface after 28h uptime on AP
*wireless dropout after 25h on ROUTER

can anyone from TP-Link respond if there will be FW update?

I don't think this will be a FW issue as I have been running 3.12.24 Build 130110 Rel.58124n FW since day 1 and have never experienced a drop-out in weeks of continuous operation.

Sounds like a "real" HW problem to me.

Hey, I found a new firmware here 130322, maybe you guys can have a try:
http://www.tp-link.com/en/support/download/?model=TL-WR842ND&version=V1#tbl_j

I have this configuration:

Firmware Version:
3.12.25 Build 130322 Rel.33803n
Hardware Version:
WR842ND v1 00000000

And the same problem is happening to me every two days (get dropped out), but in my case I could not get wifi neither wired connection until I reboot the router.
Sometimes internet and wifi lights constantly blinks and some times they are on and fixed.

Any ideas of what can i do to fix this?

i solved the problem,... just start use oldest fw 3.12.22 Build 120424 Rel.39632n

I have been using TL-WR842ND_V1_120424 for months without any dropouts.

After FW updates:
TL-WR842ND_V1_130110 - wifi dropout after 1-2 days
TL-WR842ND_V1_130322 - wifi dropout after 1-2 days

Back on TL-WR842ND_V1_120424, without any dropouts.

I'm using latest firmware and no drop outs for over a year. May be user error.
