If it continues for another week, time to call Comcast to cover your bases.
You really don't provide enough details for true investigation here, I'm afraid. Start getting into specifics about your roomies systems, and especially *what* they are doing and *when* they are using your internet connection, and we might possibly be able to diagnose something. But I'll be honest, issues like this w/ streaming services are far from uncommon.
You guys are all on the same ISP/router/system?
For the past week, I have had internet problems.
When watching Netflix streaming, it stops buffering every 5-15 minutes and I have to reload the page.
When watching Hulu streaming, it stops buffering every 5-15 minutes and I have to reload the page.
An alternate solution that works on Netflix ONLY is to pause (when it stops playing) and wait a little while, then resume playing.
When playing WoW (I know....), I get lag spikes every few minutes and get a message - "You have been disconnected from Battle.net." and then one second later - "You are now connected to Battle.net."
This is getting extremely frustrating.
I use an ethernet cable - I am not using wireless.
The ethernet cable is relatively new (just bought it about 6 weeks ago).
I run Windows Vista Ultimate on a Dell PC that was bought in the Summer of 2009.
Processor - Intel(R) Core(TM)2 Quad CPU Q8300 @ 2.50 GHz (4 CPUs), ~2.5GHz
Memory - 3070 MB RAM
I have Comcast.
My other two housemates (one wireless, one wired) both say that their internet connectivity, streaming ability, and gaming ability are fantastic.
I have tried powering down and unplugging the router/modem for 30+ seconds.
I have tried restarting my computer.
Any other ideas would be greatly appreciated.
