I dropped Comcast cable for DSL, and I'm much happier with it. My modem was here 2 days after the order.
It came with a disc to install, and after failing to establish an internet connection after 5 uninstalls and reinstalls, I finally called for tech support.
The told me I didn't need the disc unless I installed through the USB, yet there were 2 types of installs on the disc. One for USB and one for Ethernet.
Well, I was on the phone for 2 hours with tech support before it was working.
So, just in case you have a problem, call tech support and save yourself a lot of time and aggrevation.
Oh, and by the way, just in case I forgot to mention it, DUMP AOL
As far as AIM and MSN, at best you probably just have to set them up as favorites but you can still use your same passwords. You won't lose anything.
The only thing you lose is mail from AOL that you haven't opened yet. Once it's in your comp, it's part of Outlook Express or whatever you use. You will also be able to import your address book for Email addys, plus favorites for web surfing. Just a few clicks here and there and you're done. Pretty painless. The only thing that's painful is having aol rip you off.
