My S8+ keeps having WiFi problems. It randomly disconnects and reconnects. This is the second S8+ I've had and it behaves the same way. I've done factory resets, attempted every "fix" I've read online, taken the latest update, installed one app at a time, changed router settings, bought a new router and it still drops wifi. Old router was a Linksys WRT1900ACS and the new one is an EA9500. I'm at a loss. Kinda wish I hadn't sold my Pixel XL. No other device I own has this issue.
