if there are a lot of networks showing can you click on
"networks" top lefthand area - so we can see all the network information.
post which SSID name is yours, its located in the list, under network "Adapter Name" (1st column)
Note:
For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better. "A desirable signal level for a robust Wi-Fi connection will be green".
note: the signal level is a negative number, so for example -88 is worst and -40 is better
