[Help]: High latency with Mediatek mt7921 and Model: COMFAST CF-952AX #501
Comments
What about a different channel? Is it the same with 40Mhz? |
Hi @HuaZ Some questions: What numbers are you seeing for latency and how are you testing latency? You do realize that you are using the most modern version of the firmware with a version of the driver that is basically the very oldest version? What RasPi hardware are you using? I see you are using a 32 bit version of the RasPi OS (Raspian at that time possibly) which may indicate a very old RasPi device. I have seen cases with very modern usb wifi adapters where the RasPi simply could not keep up with the adapter... CPU limitation. |
thanks, "192.168.50.1 is the gateway IP address which base on the Route Netgear RX80. |
Hi @morrownr thanks
To ping the gateway ip address 192.168.50.1, the below is the result , one is 2.5ms, the next is 328 ms.
Yes, I followed the solution for a similar issue as described in the following link to upgrade the firmware, but it doesn't seem to have achieved the desired effect.
yes, it is armhf version. I also tried to disable the power-saving mode of the chip, but it doesn't seem to have any effect. |
Update: |
If this becomes a problem, check back in with a report. Keep in mind that various things beyond the control of the driver can cause ping issues. |

What happened?
I used COMFAST Model:CF-952AX with MT7921u driver on the Raspberry Pi 4B
which works, but with really high latencies。 I have also tried some older firmware versions, and the situation is the same.
Any suggestions? thanks a lot.
