I connect to the interenet via Roadrunner high speed internet (thru cable NOT dial-up) and I browse the internet using Mozilla Firefox.
My computer appears "clean" to my untrained eye. I run McAfee VirusScan, MS AntiSpyware, Spybot Search & Destroy, and AdAware these all give me clean results.
Typically, I will be browsing the internet and the longer I stay on (often just a matter of several minutes) or if I open mutliple web pages at once, the connection seems to REALLY bog down. It slows down to the point, where I will get errors messages such as "Document contains no data" or "Can not find site www.msn.com", for example, if I do not get an error message the screen will just stay there trying to open the site, but it never opens! Incidentally, when I do experience this problem in Firefox, I try using Internet Explorer and find the same very slow connection as well. Also, the cable light on the modem is always on during these problems, so I don't know if it is problem with the provider.
I notice when I unplug the power from the cable modem ( I assume this is the box with lights on it ) and let it stay unplugged for a few minutes and then replug it in and try browsing the internet again, this does seem to work temporarily. It will be back to normal speed for several minutes, but the longer I stay on and the more I browse the slower and slower it becomes. Also, when I go to Control Panel Network Connections and click on my LAN connection and disable it, enable it, and repair it this also seems to temporarily allow me to browse at my normal speed. But again this is temporary, lasting at most several minutes before slowing down considerably.
I have also shut my PC off entirely and unplugged it from the wall outlet. Same results, normal good speed at first, but becoming much slower over time.
So those are the basic symptoms to my problems. I hope this can provide enough info for someone with more knowledge than me, to help to provide some suggestions as to what could be the problem or what could be a solution. Thanks for your time!
