If you are trying to connect to the 5GHz wifi, there will be a 5g after the last 3 of the routers MAC address.Note: If your router has multiple ethernet ports, DO NOT use the WAN port to connect a computer.This means that you will have to disconnect (unplug) the cellular modem (aircard) from the computer and close the cellular connection manager tool provided by your cellular carrier or, disconnect from any LAN (wired Ethernet) or Wi-Fi (wireless) connections before you will be able to connect your computer to the router either by Ethernet cable or Wi-Fi.By default, the wifi SSID will always be the model of the Cradlepoint router separated by a (-) and then the last 3 of the routers MAC address.
Screenshots are taken from Professional version thus may slightly differ from other versions (e.g. You have now succesfully configured Windows XP to connect to EUI-Wi Fi.In order to configure the connection back to Automatic, edit the EUI-Wi Fi profile, go to the Connection tab and check Connect when this network is in range: Figure 14: Setting Automatic connection  = If the Wireless Network Connection icon is not present, this may be due to the wireless network manager of your vendor's card taking over from Windows' built-in one (Wireless Zero Configuration).Please refer to the documentation of your vendor's card in order to turn it off as this may interfere with the procedure here documented.I have two XP laptops at home that were both working fine for weeks with a new Cisco wireless router, then suddenly they both say "Limited or No Connectivity." Both of these laptops work fine with another wireless router.Also, a third laptop in the house (Vista OS) works fine with the same router that won't work with the two XP laptops. Thank You Very Much, Educated Guess I'd suggest doing this first: 1. When I try to reconnect, it grinds away for 10-15 minutes, saying, "Validating Identity" then I get the "Limited or No Connectivity" message. This unit was recently reformatted, but I haven't run malwarebytes or adaware or anything to see if that would clear it up.
