I had a brand spanking new laptop and it was doing nearly the same thing. I had to check with the maker's web site and it had a new wifi driver. All better now.
There is no reason this could be your issue. But then again, there is very little shared about your machine.

Sorry if this is not the place to post this.. I just thought CNET might be my best bet!
Also, sorry in advance for my complete lack of knowledge about anything computer related. I promise I'm not as dumb as I will inevitably sound.
My roommate and I (and everyone in our apartment building) were having problems with our internet. We would lose connection for extended periods of time. After about a month of the issue, Charter finally figured out the issue (too many people on a node or something). Since then, the internet has been working fine.
However, once or twice a day, to get the internet to connect... we 1) have to go into our "manage network settings" and remove our network, 2) we then have to unplug the modem and the router for about 30 seconds, 3) when we re-connect the devices and try to connect to our network... the first time we try it fails and says "unable to connect" before we are prompted to enter our password. But the second time we try, we are able to enter our passwords and connect to the internet.
Again, we have to go through this EXACT process at least once a day to use the internet. We have the same problem on two Windows based computers, one Mac, and one Think Pad.
Does anyone have any insight? I know this is a really odd problem.. but hopefully it can be fixed by simply changing a setting? We think something may have gotten messed up during our problems with Charter.
Thanks for any help! It would be much appreciated.
