I recently bought a new Dell XPS laptop, and at first it would not connect to my network at all. I reset the router, and set it up for WPA2 instead of WEP like it was before. I changed a few settings and it worked fine. Lately, I have been getting terrible lag spikes, i guess you could say. I play League of Legends and it sometimes will disconnect me and shoot my ping up to nearly 2000. Its usually 85-105. It will also make streaming difficult. There are two or three networks in range, and I use bluetooth. My router only operates on the 2.4 ghz band. I have a Linksys wrt160 and my network card is an Intel Centrino Advanced-N 6235.
What can I do to fix it? I think it may be just interference, but if I can fix the issue without buying a new router I would rather do that. Its also very sporadic, as in the last two days I've had no trouble, and three days ago it was almost constant.
