Upgraded to 384.6 on RT-AC68U
-noticed incredibly slow upload and download speeds on 2.4ghz, and 5ghz. Usually pull 280Mbps down and 14Mbps up when paired with PCE-AC88....Getting 7Mbps down and 1.4Mbps up.
-flashed to
384.7_alpha1-g192753589 hoping it included 21140 asuswrt architecture. Experienced the same issues.
-Direct LAN connection speed still at 300Mbps down/25Mbps up
Just in case, I factory reset to default version and did a safe clean install to ver. 384.6
-Problems persist and I seem to be getting a highly fluctuating ping now as well over WAN.
As for troubleshooting,
- I've double checked to make sure non of my cat 6 cables were loose or bad
- Attempted turning off STP, NAT acceleration, turboqam, explicit/universal beamforming (in different combinations and set as default)
- Made sure the control channels were free and isolated
- Made sure there were no conflicting Mac addresses or IPs
- Rebooted modem and RT-AC68U
- Swapped out PCE-AC88 for PCE-AC68, still same results
