I had dd-wrt installed on my Netgear R6250 router, but because I'm not very good with networking and for some reason it wasn't working very well I tried to update the firmware with Netgear's latest release for the model. The router is now listed as NETGEAR in my wireless list, and is completely open to the public. When I try to connect, the connection is ALWAYS limited. I have reset it, pressed every button, tried with different computers, tried ethernet, but it is always limited. I can't configure the router because the connection is limited. I have run out of ideas and am facing the fact that I might have to buy a new router. Is there anything I can do to fix this?
