I've owned the Asus AC66U router for a couple years now, running John's fork 374.43 V17E5. Have had no issues other than the random reboots (which seems to be common for these routers).
Now, we recently moved back from Germany (where the router was purchased). After moving into our new house and getting internet setup with the ISP, we bought a cheap TP Link Router to hold us over until the Asus showed up in our household goods shipment. The TP Link worked great and gave consistent speeds throughout the house on 2.4ghz. We have 100/10 internet and the TP Link was showing 40-80 mbps speeds depending on which room you were in. Perfectly acceptable, but I figured the Asus would easily out perform it.
Well, our shipment arrived yesterday and I quickly hooked up the Asus. I first had trouble establishing the internet connection (because I forgot to turn off the IPTV settings that were required for our internet in Germany) but once I sorted that, it was working great for a couple hours. Getting consistently higher speeds than the TP Link throughout the house at about 55-95 mbps depending on the room.
However, by the end of the day something had gone wrong and the 2.4ghz band is now crawling at roughly 1-4 mbps but never going above 5. This has been tested on speedtest.net as well as the ISP's speed tester. This is consistent on several devices (phone, laptop, and PC). If I connect to 5 ghz, I can be in ANY room and it will show roughly 100 mbps every single time.
Things I have tried:
-using different channels (1,6,11, auto)
- switching between 20, 20/40, and auto
-NAT acceleration on/off
-tried different combinations wireless modes (N Only, Legacy, Auto)
-Toggling "Optimize for Xbox"
-Factory Reset using the reset button
-Disconnecting every client except for one (trying to determine if a specific client was slowing down the entire band)
-Flashing latest firmware from Asus' website followed by another factory reset
It seems like something is limiting the link speed on the 2.4ghz band to 5.5mbps but I can't figure it out. QoS is turned off as well. There are several wifi networks visible in the neighborhood, BUT I can hook up the TP Link router and get the normal 2.4ghz speeds I was seeing before, so it doesn't seem related to congestion or interference.
Is this a sign of a dying 2.4ghz radio? Or is there anything else I should try?
EDIT: I have attached a photo showing a TX rate of 5mbps on all of the clients connected to the 2.4ghz band.
