About my wireless card...

Question

I have an Extensa 5620-4025 laptop, Friday night I hooked it up to my wireless conection and it was working fine. It worked Friday through this morning and now suddenly, it doesn't recognize my network!! I contacted my ISP (Verizon) and was on the phone with Tech support for almost 2 1/2 hours!! They told me (after trying everything they could to resolve the problem) that the problem was with the wireless card. It was not picking up the signal the Westell (Model 327W) was throwing.. I need some help resolving this issue!
