Hello, I am running Windows 7.  About every ten minutes my wireless network adapter is disconnecting.  I am running Windows 7.  Is this usually caused by a virus of some sort?  It's not like it's on a timer from some kind of script though.  For example it's been working right now at least for the past 15 mins.   

 

The behavior is inconsistent also.  I say this because when I right click on the disconnected wifi connection (lower right in the tray) and select "Troubleshoot" about every one out of three times Windows will successfully reset the wireless network adapter.  The other two times it says it can't.  Does this provide a clue as to what it is?

 

Any help much appreciated.

Something that will cause this is wireless interference on a certain channel.

 

Logon to your router and change the Wifi channel (normally auto, channel 6).

 

Try channels up and down and see if that helps.

Ok thank you guys.  I am actually on a shared router in an apartment building, and it's the summer and a beach area so more tenants.  I guess I should ask the building manager to switch the router to a different broadcasting channel.  One thing I noticed though:  after I posted around midnight the connection strength increased and the wifi connection remained connected for an hour straight before going to bed.  

 

Ok thanks, I am assuming based on this information I should still run the utilities as well as ask the guy to switch the broadcast channel.  I will do these and then post results here.
