hi at the very begining i dont know what my firmware version is so sorry for that i just wrote it 1 to let me post this i have an internet with the speed of 1Gbps and i get 850Mbps down and 314 up on my phone with wifi but on pc with Archer T3U AC1300 i get 250Mbps down and 250Mbps up which is rather disappointing with the fact that its written 866 Mbps on 5 GHz and 400 Mbps on 2.4 GHz. im not even getting the speed of 2.4 GHz on my 5GHz channle so i was wondering is it something ive done wrong or i should do differently or its just a lie what is written paper can you plse help me out?
