my laptop does not see ssid of the xfinity router, i can conntect the same router using my desktop. any suggessions.
Is your desktop connecting successfully using WiFi or is it connected directly via ethernet?
What make/model/OS is your laptop? Are you sure your laptop's Wireless adapter is activated/turned on? Have you looked at your laptop's Wireless WiFi adapter properties to see if there is anything to change, e.g. Wireless Mode or if the Driver needs updating?
If your desktop is connecting via WiFi, then you might compare your desktop's Wireless WiFi adapter properties with those of your laptop.
