tp link wr941nd severe packet loss to gateway

Hello folks,

Here's my issue:

I hooked up a friend of mine with a router tp link wr941nd (802.11 b/g/n) after a couple of minutes of setup I got it up and running. After two days with no problems the router suddenly stopped providing Internet access over the wireless.

When I opened and reviewed all the WAN\WLAN settings (like WAN ip,gateway, dns, etc) everything seemed OK. I pinged the router and it was also fine. No noticeable issues. When I pinged the gateway, severe packet loss occured (which makes browsing pretty much not possible at all).

The router works ok at home but not at my friend's. Now some people suggest that I should change the wireless channel the router is communicating on and that might be the issue (Haven't tried that yet). Can someone confirm that this might causing the problem? Interference with other devices where my friend lives and that is because at other places it works? Consider that there is no packet loss to my router but to the ISP's gateway/internet.

Below some pings I did:

Code:

...CROP...
ping to router local ip

For proper confirmation, try connecting the laptop with a cable to the router and see if u can browse and have good ping replies.
if this is ok when hard wired then go ahead and change the channel for its most likely that there are some interferences at your friends home.
Try using any one of the non overlapping channels... 1 6 11
Let me know how it turned out.
