Linkys Wireless Network Connection Problem

I have a Dell Inspiron E1505. I use linkys as my wireless network. Every time I am online, I lose my connection. I have gotten the message that my connection is weak (and I have very few "bar lines" highlighted).

 

My husband also has a Dell laptop but does not have this problem. We use our laptop in the same location.

 

I have tried using the wireless network in a different part of the house and it is better in some places than others. Under troubleshooting, moving to a different location is one of the suggestions. The problem with this solution is that the place where I need to use it most often is the place where I constantly have this problem.

 

Has anyone else had this problem and found a solution.

 

Thanks
