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
