Im using a Cisco x3000 modem/router here in my apartment, and before that, I was using a regular modem, which I connected to my 2tb time capsule. Everything was fine today, then, after watching a youtube video on my Apple TV, the wifi is extremely slow, under 1mbs, and the ping is around 300. I went to the x3000s page, and rebooted it, it would then work fine for a few minutes, but drop again to less than 1mbs/300+ ping. But, on the X3000s page, its showing my upload/download speeds as normal. This happens not too often, but it has happened to me before. Its the reason why Im using the x3000 now, instead of the TC, because I thought it was an issue with the TC. Last time it happened, I changed the password to the wifi, and it worked for a few days, but did then this happened. It also happened one time after I uploaded one photo to photobucket. It got really slow, then after a little bit, it went back to normal. Thoughts?
