Flint 2 slow wifi speed

[KrZ]

I previously had an Asus AX3000 v2 router and achieved 750Mbps Wi-Fi speeds. I recently purchased a Flint 2 router, and the maximum I could achieve over Wi-Fi was 550Mbps on each client (AX200, Honor Magic 6 Pro, Mediatek Wi-Fi 6E MT7922). I have firmware version 4.8.3. I'm running 160Mhz on the 5GHz band, and the devices connect at 2402/2402 (Mbps). I can achieve maximum throughput over Wi-Fi on my LAN, but the internet speeds are poor.

My connection is 1000/300Mbps PPoE.

Try enabling network acceleration and setting it to hardware mode.

[KrZ]

Network Acceleration → Hardwarde Mode → ON

Packet Steering → ON

and I even enabled Hardware flow offloading

I have no idea how to get higher speeds on this router

Try using the openwrt24 version. Same results??

[KrZ]

op24 the same result wifi speed, op24 wifi range is weak

Strange, I get quite good speeds on Wi-Fi on Flint2 op24 version.

2 Gbps symmetrical.

This is PC running on Intel® Wi-Fi 7 BE202

This is S25 Ultra

I have no idea why mine is so bad, does anyone have any ideas on how to fix it?

Do you get higher speeds with a physical connection?

[KrZ]

Ethernet LAN

WIFI 5GHz 160MHz - 1 meter from the router

Can you once try at 80mhz mode with channel set to auto?

[KrZ]

why wifi AX mode doesnt work? because the same result on 5GHz 160MHz

[Aashish.007]

At this point I guess only a router firmware reset would help? This same problem is faced across all devices right?

Also for 80mhz 2x2 you can get 1200mbps link speed.
