Everything is in the name of the question basically. I have TDS wifi provider. Gigabit fiber internet since it is the only fiber option. Crappy speeds even when only one device is connected 60-150 mbps. But when the technician guy connects he gets 300 wirelessly and 800+ wired. I tried switching the original router they gave us (eero) to a Reyee RG-E5, but unfortunately it showed the exact same speeds even on a single connected device (iphone 14). I am tired of these speeds and I am crying out for help. The Technician kept telling me it was the amount of devices connected but proved that to be wrong after I connected my new router with only one device connected (my iphone) and still got the exact same speeds (60-150 mbps). I looked where the main router was connected to and it was using a CAT 5E ethernet cable which should be able to hold up to a gig of speed but Idk. Please help!
