Guild Wars 2

My issue: Constant error 7s (disconnects). I should add that this only happens with GW2, every other games run smoothly, net-wise.

Any recommended configurations I should make to my modem (via website 192.168.1.1) for a faster and more stable connection?
The site where you have these tabs: HomeStatusQuick SetupWireless SetupUtilitiesAdvanced Setup.

I recently changed my channel from Auto-detect to Channel 11 as I heard that would give you a more trustworthy connection. Other than that, everything is in its default state.

Thanks in advance.

Playing online games via wireless is never recommended due to reliability issues, usually interference or weak signal is the cause.

Thing is, my room-mate plays only few inches from me, wireless as well. Same network, same settings, etc. I am the only who keeps getting disconnected. Tried playing wired while she was playing it wireless… no difference. Both laptops recently sent for checkup and even went through a full reformat. Tried without any antivirus/firewall running, no luck.
