I have a Magbox 254 with a dwa 160 wifi adapter that suddenly quit working. I go to wifi setup and select my router and a check mark then shows beside it and and the ip address is also filled out. When I go to reload portal I get NOT CONNECTED message. I tried another wifi adapter with the same results. I have a linksys router that is only 20 feet from my magbox. If I hardwire it works fine. Thoughts?
