Not at all...These LCO and even ISP is misleading us...The speeds depends upon the wifi PHY speed...Yes we will get below or up to 50 in wifi 1,2 versions...They all say about 5MHz dual band routers to get full speed...If we connect using LAN cable then we will get full speed...I have posted speed tests in my RN10 Pro ....U can check there...It's having wifi 4 PHY 150...But it's up to 150 Mbps..
All depends on
