I've got a problem with one computer that is driving me mad! For a couple of years I've been dealing with it continuously dropping its connection with the internet, while still successfully pinging the router.
I ran a ping test with two computers simultaneously, pinging both the router and Google's static DNS (8.8.8.. They both work fine for a bit then the troubled computer times out from the DNS but is still communicating fine with the router, while the other computer remains connected to both. Simply turning off the computers WiFi and then back on again regains the connection with the DNS. The problem doesn't occur when using an ethernet cable.
I've ruled out firewall/software issues as I did a clean OS re-install and the problem persisted while the machine was empty of any files or programs, and have done all the usual network troubleshooting and so on.
Any ideas where the issue could lie? Is it a problem with the computer? I've attached a screenshot of what is happening.
