JAWhitney,   Try using these Recommended Wireless Router Settings in your wireless router and then see if you can connect. I use channel 11.   I haven't had a wireless device that couldn't connect to my wireless router.     Rick
I have an Inspiron 1520 with a Dell Wireless 1395 WLAN MiniCard and a US Robotics 8054 router.  My computer will not connect to the internet via my router, but I have been able to connect to the internet via a Linlsys router.  My router is working with my other Dell Laptop that is using an Intel Pro/Wireless 3945ABG.  I would appreciate any help or ideas.  
Cannot connect to my wireless router but can connect to others
