Hello, I've been having some wifi issues recently. I use ethernet and I have my ethernet cord connected to my extender. The extender is a TP-Link AC2600. I get download speeds and upload speeds of about 130+ on the google fiber speed test website, but my websites have been loading slowly, videos are laggy or don't play at all, and I'm having lag issues on the games I'm playing too. Not really sure what do, I've restarted my wifi, moved the extender, changed the ethernet cable, updated everything, tried using a vpn and nothing seems to be helping.
