Hi, some of laptops coming with pre-installed software like Dell with SmartByte (if you found uninstall or disable it) . So these will not let you use your full network speed.
And my recommendation if you still getting your poor speed. Try to not separate your bands. Leave them with the same name and password. And your devices will connect to the better one. For me this helps.
