I have a WRT54GL router that is working to provide internet access via the 4-port hub, but is not working to provide wireless. It did at one time, and on occasion, still does, (rarely), but most of the time, the wireless doesn't work. I tried updating the firmware, but that didn't do any good, and I also tried changing the wireless encryption methods, (was previously unsecured), and this didn't help either. It seems like it just doesn't want to allow wireless connections anymore, even though occasionally my laptop will pick up the wireless network. I have tested my laptop on other wireless networks, so I know the laptop is working. Any suggestions before buying a new router?
