I have two ax50 routers and started having issues with the newest one purchased.  I have tried a lot of things to resolve the issue, factory reset, adjustings settings, etc.  I have used both routers and upgraded firmware on both, they are both v1.6.  Recently I have started to have issues with speed and they were not an issue before.  Speeds are slow on ethernet as well as wifi and nothing seems to help.  I don't know where to go from here other than buying a different product to avoid this issue all togehter.
