High Latency over all Wi-Fi bands on RT-BE96U

[savage24x]

Hi All,

I have been having issues with my RT-BE96U ever since I purchased it. I am upgrading from a RT-AX86U due to having a 2gb down/200mb up plan from my service provider and many Wi-Fi 7 devices. All devices have a high latency issue over all wireless bands. I have focused my test on the 6G band with a Qualcomm FastConnect 7800 card. I also test with my Intel BE201 and BE202. Online gaming and streaming is completely impossible. Has anybody ran into this issue before?

1. Tried multiple firmware versions (OEM and ASUSWRT): 3.0.0.6.102_32882, 3.0.0.6.102_34488, 3.0.0.6.102_37024, 3.0.0.6.102_37031, 3.0.0.6.102_37038
2. Exchanged router for new one at local retailer
3. Separating wireless bands (2.4G, 5G, 6G)
4. Creating a new MLO network
5. Restoring to default settings and followed quick setup
6. Connecting to ethernet (issue resolved)
7. Replaced RT-BE96U with RT-AX86U, no latency observed with the latter.
8. Verified no channels conflicting with neighboring networks.
9. Ping test to router on 6G band (changed router to 192.168.1.X subnet. (see above screenshot)
10. Disabling Both beamforming options, WMM APSD, MU-MIMO, and Airtime fairness.

Speedtest directly on router:
