The router's firmware was out of date.
I'm completely new to wireless networking and I'm having a problem with my router's security settings (Belkin F5D7230-4). If I set the router to WPA security, I can connect to the internet through both a wired and a wireless connection. However, when I switched my router to WEP 128-bit security (so that it's compatible with my network camera), I can no longer connect to the internet wirelessly. My wired connection will still work, but the computer says it can't connect to my wireless network. Any suggestions? Thanks.
