currently i have this router with an iphone 6. i have all the wireless configured manually, 5ghz VHT80 channel 161 , 2.4ghz channel 11 and 40 i believe for the mhz. anyways on the 5ghz and my iphone 6 if i walk outside my house and do a speedtest i get 30mbps, if im inside my room i get my full 180. heres where it gets weird. if i do that and walk back inside i still only get the 30mbps, only way to get it back up to the 180 i pay for from my isp is to disable wifi on phone and reconnect. any reason this could be happening? its like the link rate speed doesnt auto refresh when technically im closer to the router once ive come back into the house. thanks
