+ 0 Votes Just a guess nekoz Updated - 1 year ago If I had to guess...when it does connect and allow access...the IP and Subnet look much different. The only fix I could offer is to check when it works and assign a number close to the working number next time. A common numbering would be 192.168.2.X. X = some random number assigned by the wireless router. I would probably try 192.168.2.49 or 192.168.2.98. That way if they have a DHCP range of say 2-50 or 2-99 you would be in the upper range(last to be assigned). As for Subnet, when you see it work, use that exact number again. Be sure to switch it back to "Obtain an IP address automatically" when done or it might not work at home.
