I purchased the Archer AX50 yesterday but I'm finding the speeds are slower than my old google wifi router on iPhone 12, iPhone 11, and iPhone X. I get a maximum of 250mbps if I'm lucky! On my old mac

Hello . I've just got my archer ax50. i did the set up and i did a speedtest and on 2.5ghz i've got 250 mpbs so far so good. and then i changed some settings and the 5ghz and 2.5 ghz went down to 5ghz
