I think I know the answer and I think it's probably 'just go get a new one' but, in case not, here goes! I have a D-Link DI-524 (802.11G) that works perfectly fine for my laptop, my work laptop, my phone and my son's phone. Everything connects and stays connected, no issues at all. My son's laptop will NOT stay connected and boots everything off when it tries to connect. It finds it, connects, boots me off, then disconnects. Repeat cycle endlessly. He has a Lenovo G530, I have a G550 so they are basically the same. I have gone into every setting I can find/think of and it seems OK. I have reset the router back to factory and reset it up. Nothing works. His laptop just won't stay connected? I did look for a firmware update but the one I find is a lower version than I have on the router, but a 'newer' date. Ummm, yeah, it was discontinued/end of life in 2008 so it's old. The stupid thing should work on his laptop though, since I have no trouble with anything else. Any ideas??
