I have upgraded to 300 mbps line from Airtel in Delhi. Now airtel has changed the regular Huawei modem with some cheap chinese modem cum router (GPON HGU brand). I want to connect my Neatgear Nighthawk router which I was using earlier with my old plan. I am able to connect it but am not getting the speeds. If I use the chinese moden/router I get 300mbps on its 5G band and around 30mbps on its 2.4G band. But in the netgear I am getting only around 100mbps on both 2.4G and 5G. I do not see any option to specify speeds over lan in both routers. Any suggestions please ?
