Laptop will not connect wirelessly, other devices do

Hello...I have a Linksys wireless router connected to my Comcast cable service, and have never had a problem with my connection before. Other than the laptop, I also have a T-mobile hotspots phone that works on Wi-Fi, and I also have an iPod touch, that I just set up on wi-fi last week. Starting yesterday, my laptop can no longer get on the internet. The Dell network assistant shows that I am fully connected, but I can not browse web pages. If i plug in directly via ethernet, I connect without a problem. Also, my hotspots phone and iPod touch are connecting wirelesly with no problem. Any suggestions? Thanks
