My Grandma's Windows 7 computer lost it's wi-fi connection a few weeks after my cousin messed up the computer. He turned on the computer, got an error message, then decided to restart the computer with the power button. It's unclear how many times he hit that button. In the event viewer, there were numerous error messages related to that.
Since then, the internet has not worked correctly. First, it kept losing it's connection every few minutes or so. But then, at some point, it stopped connecting at all. The other computers and devices don't have problems.
In the control panel, it indicates that the wireless network connection adapter is not connected. No one has changed anything.
I have seen the following errors in the event viewer:
TCPIP - Event 4205 - Autoconfigured route limit has been reached. No further autoconfigured routes will be added until the interface is reconnected.
Browser - Event 8033 - The browser has forced an election on network \Device\NetBT_TCPip_(insert name here) because a master browser was stopped.
iastor - Event 9 - The device, \Device\Ide\iaStor0, did not respond within the timeout period.
DNS Client Events - Event 1014 - Name resolution for the (insert name here) timed out after none of the configured DNS servers responded.
I cannot figure out this problem. I have tried several things, but nothing works. Any suggestions?
