I've went through terrible lag spikes for the past 3-4 weeks and I've finally diagnosed the problem as Time Capsule's standard wireless connection (not related to backing up, etc.). Long story short, in a last ditch effort after contacting Comcast, researching, I took out my old Belkin router and it works perfectly. I saw a post on these forums where one person had similar problems. I'm going to post images of my connection summary. Also, both wireless signals on Time Capsule are causing these lag spikes, which are 3-45 seconds long and extremely frustrating/apparent when gaming. If anyone can provide any insight into why my Belkin router works perfectly at 100-130 transmit rate and Time Capsule does not at 225-250, or if I can fine tune Time Capsule's settings to make it work, I would really appreciate it. "oreo" is Time Capsule, "Oscar" is Belkin. Thanks!
