My wifi router is AX4200. The wifi download speed is fast but upload speed is slower.

Hi. I just bought AX4200 for my apartment.

Our apartment have apartment wifi, but sometimes it makes me annoying so I bought new wifi router, which is AX4200 and I installed it.

The download speed is increasing 250 to 500 but the upload speed is decreasing 230 to 50.

I checked my firmware version but it says it is latest version.(1.0.11.112_2.0.77)

Does anyone who can fix this problem??

Thank you!

Seems you have a very old firmware. Latest firmware for RBR750/ RBS750 is 4.6.9.11.
