I connected my new switch as instructed and I initially had great internet speed.  After I tried to connect my deco mesh router, I lost internet connection to my computer (still hardwired to the switch) and cannot get it back through the switch. The router was also not able to connect but a different computer was able to connect. Connecting my computer directly to the modem works fine. I've tried restarting everything several times with no luck. I've also tried using different ports.help
