upgraded my mt2500 to 4.4.5 stable last night, just found out my main router (rt-ac68u) detected the mt2500 lan connection at 100mbps, i pulled and replug the lan plug it then go back to a 1000mbps connection
don’t know how to recreate but this had happened before at previous firmware versions
once few days ago i did a speedtest and the speed maxed at 100 when i expected 200+, it returned to normal maybe after i rebooted the router, cant remember
then this time found out its detected as 100mbps connection when i visited the main router page
only clue i can think of is it all happened after each firmware upgrade, but not verified
