I've previously been connected to my router using tethering via a Samsung Galaxy S5. I recently upgraded to the Archer T8E, which proved to be worse than the S5. Every 2 minutes, I lose connection to the router, games are unplayable, and I can barely surf the web. This worked fine on the S5, apart from occasional lag spikes in games. I assume this is a settings thing, could anyone lend me a hand? I'm a pleb when it comes to wireless internet.
