I recently reformatted my Dell Dimension 8300 and reinstalled all the drivers that came with the computer when new. I also had to purchase a new maodem/router because the old one failed. The internet is present on my computer but the pge that allows nay action comes up with the title THIS PAGE CANNOT BE DISPLAYED. What, if anything, can be done to make use of the internet?
Did you get the new modem activated for service by them ?
What browser and version are you using? The ancient IE that comes with XP my not be supported by Comcast's website anymore. Even other browsers may only support old versions that may not be supported. You can always call into Comcast to get the modem provisioned.
