I have been having an issue with the "connected but no internet" message on my wireless devices. All the firestick tv seem to work fine. Laptops,phones,and exercise bikes get the message or have very slow speeds. I have replaced both router and modem. I have hardwired the bike, and laptop directly from the modem and it works, but if I come from modem>router via lan> to bike it doesnt work. Speeds from modem via ethernet to laptop are over 200mbps, wireless is less than 50.
