From my new computer that I built like a week ago:
Anyone know what might be causing this? I did a power cycle of my modem/router/computer, but that didn't help. I'm wondering if its comcast just throttling me since I to download a lot of updates over the last few days.
Are you using the same wireless adapter?
Is it in a different room?
Have you tried contacting Comcast?
Are you using the latest wireless drivers if you're using Wireless?
