Five years ago cable speed was nowhere near what it is today. As your cable company upgraded they should have offered a newer modem for swap. Your modem is probably out of date. You might try updating the drivers just to be sure. Else, a new one is on the horizon.
and life goes on...
I have been having problems with the speed of our internet connection and am wondering if our cable modem could be failing.
We have 3 computers connected through a Linksys G router, maybe about a year old. That is connected to a Toshiba modem that we got years ago when you could only rent them through the ISP, and then we subsequently purchased. So its at least 5 years old, probably more.
All 3 computers have the same problem, so it doesn't seem to be related to anything specific to the computer, such as a full cache, corrupted files, etc. The problem happens no matter what application is being used, IE Explorer, Firefox, Outlook, etc. Each system has different virus protection, etc., so again, I don't think its anything related to one of the computers.
Resetting the modem and router helps some, for a little while.
Any thoughts? What are the symptoms of a modem that is failing? How can I measure the speed of the connection?
