I must have done something wrong here. Have desktop and laptop and wireless router. Desktop is Enet via router , my choice. Laptop wireless. SSID shown on router is (Using fake one here)... 6ABC2. When desktop is connected it shows Internet Access 6ABC2 2.
I must have screwed up trying to set up wireless on the desktop. My laptop has always been ablr to connect via the router wireless. I ASSUME laptop is looking for 6ABC2 and fails. Laptop uses IBM access connections which I love. Oh I use laptop at a hotspot on business, works fine.
I'm not familiar with your type of router but SSID names on routers are often a bit buggy especially when the old name is a bit of the same as the new Name.
I suggest filling in a complete other SSID name save your settings let the router Reboot and after the router is up pull the powercord and wait 10-15 seconds and put it back in so it really resets itself.
After connect your PC's/Laptop and see if it works!
