This question gets asked very often. You can't solve a coverage problem by picking the best router. This issue is thankfully discussed many times and we have one of the solutions in post 18 of this forum's sticky.
If you want to (re)test this area be sure to get the store return policy in writing as you test routers for coverage.
I currently have my wireless router in my finished basement. This is where it has to stay and is going to stay. It's a ~6 year old Linksys, nothing fancy. It's doing a fairly good job, but I am not getting great signal strength on my wireless devices (laptop, desktop). So, I am looking for a new router.
I don't need any of the fancy features, I just want a powerful enough router to push a strong signal from the basement to the 2nd floor, where my desktop is located. Currently, when I'm on my desktop or laptop I get about 3 bars (out of 5) for signal. I also connect my Xbox 360 and Oppo blu-ray player to the router, but I never have everything running at once.
Any recommendations you guys can give would be appreciated. Thanks!
