Something strange is going on and I dont know what to do. My internet signal is "strong" but i get very little download and upload. I thought I fixed it but now its happening again. Could it be a virus or something? I really dont know what to do and I could really use the help.

I found out that when I change my internet channel it works (mostly) is it possible that there is a virus or some reason that is looking for my normal channel. Also my channel changes everyday so I have to apply the change everyday it take a long time and I would love it if I didnt have to do that.

If you live in crowded area with a lot of wireless networks around you, it is normal that some channels are used often and that can cause a problem if you use the same channel. 

I don't know how to set some channel as default, you should ask here: http://www.bleepingcomputer.com/forums/f/21/networking/
