I just started Comcast service to replace my DSL. I have two Android smartphones, a Win7 Laptop (Compaq Presario) and a Win 8.1 Laptop (Toshiba Satellite.) All connected easily with the DSL service but the Satellite running Win 8.1 will not connect using the Cisco modem/router. I have worked for several hours on this. Comcast can't help.

    There are several Internet articles alluding to similar issues, but the issues are not quite the same and they have complex, vague or questionable solutions. Obviously many Comcast customers must be running 8.1 successfully.

     This issue is wireless only, no problems with ethernet.

     Any ideas? Thanks for help. Frank

Hi Frank,

Not sure exactly what you mean by >> Comcast can't help. << > Do you mean can't or won't help ?

 

Do they supply the Modem, or are you using an older one you already had ?

You are normally provided with a booklet on "How to connect", and you have done this with a laptop, but not the others.

 

Your other units need the same "treatment" of entering a password or logon sequence (they will all be the same off one modem) to match your modem login.

If you have instructions, they will all be the same for each unit with the same Internet Service Provider (I.S.P). I run a desktop, a wireless laptop, an iPhone, and a Kindle reader, so all needed to match the Modem that my I.S.P provides. If they do not match (or you have missing drivers) they will not connect..

 

Please try and contact Comcast, or wait for Queen-Evie, A moderator from Comcast forum.

 

Thank You.

Thanks, I think I will try a Comcast forum- good advice. Comcast said it must be a Win8.1 problem, but it must be incompatability between Win 8.1 and the Cisco modem, because the 8.1 machine connected flawlessly when I had a Verizon DSL modem and connects fine to an Amazon-purchased modem which is Charter-compatible and exists at another location.

Home - Comcast Help and Support Forums

This is a link to the forum for you :)

It seems like they have not given you enough information on "How to set up Wireless Devices.

 

Always drop back for more help.
