epidemic

hello all, I had noticed that my connection didn't seem as fast as it used to be, so I started looking around at all these connection test sites, and for some reason i am getting a REALLY BAD connection using charter, i thought is might be my puter, but i took it to my friends house (also on charter) and I'm getting a great connection there. Anyone know whats going on, or should i just call charterand have them poke around for a while? also is anyone else having this problem? Connection info DL Speed 30kb/sec connecting at 10.9% of the average charter speed
