@David-TP Hi, I'm using 1000Mbps broadband and the average download speed is about 500Mbps. After upgraded to 1.2.3, my upload speed is about 1.9Mbps compare to 396Mbps whilst using the router...

After upgrading the firmware version 1.2.3, the upload speed became very slow. Is anyone experiencing the same issue? Any chance I can downgrade to the previous firmware version?
