I have a WNDR3700v3 router and have had next to 0 problems out of it previously. I recently reinstalled Windows 7 on my computer as an annual ritual, and ever since I have been experiencing random latency spikes. At first I figured it was my ISP doing something but it continued. Then I decided to ping my router and noticed that sometimes I receive a ridiculously high ping for being internal. (Upwards of ~1k-1.5k ms) I have not changed a single setting on my router in some time, and I am leaning towards it being something with my PC given it has been the only thing to receive a change. I have installed the latest drivers since I reinstalled. There does not seem to be any pattern to the spikes and they are sometimes upwards of 10 minutes apart, or as close together as ~1 minute. I am quite lost at this point.
