Alright I'm not sure what bits of information will be helpful and what won't, so I'll just give you everything I know.
My router is a Westell Versalink Model 327W
I've got Verizon DSL, with 2 computers connected directly to the router by ethernet cables and 2 laptops, one from a few years ago connected wirelessly and 1 new one that won't connect.
The one that won't connect is a Dell Inspiron 1520, and I had called Dell and we figured out that it's the router with the problem, not the laptop.
-The dell recognizes that my network is there at full strength, but won't connect(It's got a WEP, but I know what that password is, so it's not that either)
-Occasionally I connect to my neighbors unprotected wireless, so I know that my laptop CAN connect wirelessly. The signal is extremely weak though so I can't just leech off of theirs
-I am able to connect to my network directly using an ethernet cable
If theres any other things you need to know, ask and I'll find them out.
Thanks for any help
