I don't usually update my gpu drivers unless I need specific driver support for something (game or anything else). This was fine when I was on Radeon - found a driver that worked, and stayed with it until I needed the update.

Been using a 4070 Ti Super for about a year now, my first Nvidia gpu in 10+ years. When it needs to be updated, I lose my internet until I update it. Has happened four times now over the last few months. First time I called my ISP and they had to send a tech to re-program the router (theirs). Internet worked for two weeks, then went out again. On a whim I updated the gpu driver and internet came right back. Happened again a few months later, updated the driver, internet came right back. Happened a month ago, again updated, again the internet came back immediately. Then it happened again this morning.

Usually the pattern is: check router, check anti-virus, check wifi, check windows. It's always the updating the gpu driver that fixes it. The router is rented from the ISP, wifi is always off, and Windows never gave me this problem before I switched to the 4070TiS (previous gpu was a 7900xt). All computers on the network lose internet when this happens, not just mine.

Process of elimination - the problem is Nvidia's driver delivery system, which crashes my network unless I update. I'm really close to just selling the 4070TiS on Ebay and moving back to Radeon b/c this is completely unacceptable. I don't want to, as it does literally everything I want it to do. But I can't have my internet dropping every time Nvidia drops a game-ready driver for a game I'm not even playing.
