x90m7 wireless

I have a x90m7. When I use in the office either wired or wireless (cisco AP) no issues. I try to bring the machine home and connect to my home wireless either a uverse wireless AP or Aruba AP i can make a connection and go on the web for about 15 seconds then lose my connection and can't reconnect with out a reboot. Anyone else experience this or have any suggestions? I am one rev behind than the recently posted image (11/29).

Thanks,
Glenn
