I have seen increased speed on my AC wirless since installing this router.  I did try 2 different AX wireless adapters, they seem to start at higher speeds-1.0-1.2Gbps, Often setting around 960Mbps.  All of which I was fairly happy with. But often times they drop quite significantly, someteimes down to 500Mbps.  It got to the point that it seemed that my wifi AC adapter was actually consistantly faster than either of the wifi AX adapters (1 TP-Link, 1 Wavlink) I tried.  I did some research, ran a wifi analalyzer and tried to set better channels.  Tried a lot of different things.  Well in the past week I have gone back to my wifi AC adapter, and it has been at 866Mbps pretty consistantly, for about 3 days.  Then it dropped speed.  I put a new firmware update on my router and rebooted the router, now wifi AC is back up to 866Mbps, for about 2 days, then it got slow again.  I rebooted my router again and now it is faster!  I did notice on the router reboot option that it is clearing cache.  So maybe clearing cache resets arp, etc and gains bettere speeds on wifi?  I really don't want to have to reboot my router every 2-3 days.  Is there a fix for this?  Or would I be better off getting a different router?

Thank you.
