Flipping from wired to wifi can invoke "issues" since Windows may need a helping hand to release and renew the IP information.

NO OS WAS NOTED SO I CAN'T SUPPLY THE COMMAND FOR THIS.

For NT/2000/XP I would open a command line and type ...

IPCONFIG /RELEASE

Then

IPCONFIG /RENEW

Then I would use

IPCONFIG /ALL

To see all the numbers to see if it setup proper.
