Problem's in the title.

Additional info:
Router - TL-WR1043ND (TP-Link), latest firmware.
Wireless security - WPA2/AES.
OS - OpenSuSE 12.2 and 12.1 (two computers).

After reboot everything is fine, after high net load (I think) it slows down and router admin becomes unavailable, although internet is still reachable, just VERY slow...

When did this start? Are you rebooting the computer or the router? –  Synetech Sep 25 '12 at 17:25
    
Not sure when it started, I used wired connection for a long time. Rebooting router, it happens on two computers, so the problem is at least in the router... –  Devenv Sep 25 '12 at 17:29
    
Hmm, it sounds a lot like what I recently started experiencing with a D-Link router. I’m wondering if maybe there is a new malware that triggers a vulnerability in older routers’ firmwares… –  Synetech Sep 26 '12 at 1:01
    
I'm on Linux, no malware here :) –  Devenv Sep 26 '12 at 13:46
    
I’m not talking about on the computer, I’m talking about on the Internet. For example, a worm may scan a series of ports, and the scan may be configured badly (purposely or accidentally) which then triggers a bug in the router firmware. –  Synetech Sep 26 '12 at 15:53

You might try an alternate open source firmware like OpenWrt, which is compatible with this router.

Thanks, I looked into it, left it as a last resort :) –  Devenv Sep 25 '12 at 17:28
    
+1 My Linksys routers suffered the same thing. Moving to dd-wrt fixed it for me. :) –  Ben Richards Sep 25 '12 at 17:42
    
Marking this as a right one because this is what I'm going to do :) –  Devenv Sep 26 '12 at 13:46
