Xbox 360 can't even detect router in the house at all now???

Question

My Xbox 360 was working just fine then my internet went out got that fixed now my Xbox 360 can't even detect a router in the house anymore. It can't detect a network,it doesn't even give me a wireless option to connect to on my 360,I ran the Linksys Easylink Advisor,it shows my 360 on there but it isn't lit up like it use to be. I called Linksys they can't even get it back online......I don't know what else to do to make it detect my 360,when they fixed my internet they bridged my router,don't know if that has anything to do with it or not.
My Linksys Wireless Router Model # is WRT54GS
