Lately, I feel like I've been relegated back to dial up speeds.
It comes and goes. Things will be going peachy and suddenly I hit a wall. I'll get the dreaded "can't find server" page after waiting for a minute or two and then the third try might go through.
My room-mates have been experiencing the same thing. The modem/router is about 4 or 5 years old, and is hot during operation, which I guess is normal. I know that heat is what ages laptops, could this thing be on its last legs? Our DSL provider says everything is OK on their end.
I don't want to be like an amatuer car mechanic and just be a "parts replacer" w/o being able to diagnose the problem, but I'm thinking a new modem might be worth the gamble.
