Cannot connect to wireless from internet recovery

Have 2011 13" MacBook Air. I erased my hard drive using cmd-r at startup to enter disk utility. When I restarted, Internet Recovery automatically started to try and connect to my wireless. It never asked for a password. It never connected. Error "-2002F". Tried it again, this time selecting a new network, entering my network name and password. Still will not connect. Have repeated many times. Looked at my access logs on router, it is not connecting. What else can I do?
