Hii, I had the same problem with TL-WR841N , and it was very frustrating. i too downloaded latest firmware from TP-Link , but still the same issue persisted.

FINALLY here is the SOLUTION. for all TP LINK Users having this issue (and there are many).

I downloaded and upgraded the alternate firmware from DD-WRT.com and its running fantastic. Its been running nonstop since the installation.
You will have to search for your Router in their Router Database. and follow the procedure.
i.e download the .bin files and upgrade firmware.

Believe me, there will not be the freezing issue again and no torrent issues either . F*** TP-LINK and their Firmware .

Ok! Thanks man! That's not a solution but...

Do you mean WAN connection? Are you losing IP address from WAN interface?

I have the same problem so i continue this topic.
I had a TL-WR841N v8 what i brought back with the same type of error than i got v9, but the problem hasn't been solved.
I lose internet connection very frequently like in every ~5 ~10 mins.
I
use the latest avaliable frimware and i have dynamic ip. I lose connention on both wifi and wired connections. Then after half minute everything seems to be working again. I have one pc connected to the router wiredly with Win7, and 1 laptop with Win8.1, and 1 desktop with Win7 connects wirelessly. (The laptop seems to be loosing connection more frequently...)
I have tried to increase the lease time of DHCP, use Static Ip without any luck. (Third party frimwares not avaliable for v9 yet...)

This is how my log looks like: http://pastebin.com/tFjtkWLV
Your support is very appreciated.

I think your ISP may have some limits. You had better contact them first.

This even happens when only one computer is on the network and there are no limits at my ISP. I have also tried to connect a computer directly to the modem and there isn't seem to be any problem with the internet connection.

Openwrt and DDWRT will be better

Yes, exactly! A strange phenomenon!

Problem solved! Make changes as picture:


Ghange the default DHCP setting (address lease time) of 120 in 2880 (maximum)!

And now is everything ok?
