RT-AX88U Pro Max Wifi Speed

[lawk]

Hello,

I now have 1Gbit symmetrical WAN from my ISP.

I noticed that my Wifi speed caps out around 750-790Mbit up and down. Test is performed within 50cm of router. Is this normal or can I achieve higher speed with some setting?

Current setting is to seperate 2,4 and 5ghz ssid. 5Ghz has 160mhz enabled. There is one additional 2,4ghz ssid for IoT. I also have a wireguard server enabled, but all tests are done without using it obviously. My laptop with Intel ax210 caps out on WAN speed tests 780Mbit.

Same goes for iPhone 11.

on wired LAN it reaches around 930Mbit.

Can I suggest you install iPerf3 on a PC and the same on your laptop and test using that? It's much more reliable than going via the internet.
On my RT-AX86U Pro I could hit close to 1000 Mbps testing like that using my phone and Magic iPerf, having 160 MHz channel bandwidth enabled.

"wlink" is a shell script which gathers and presents connection information, the rest should be self-explanatory.

WAN LAN and WAN Wifi Speed improves when DISABLING WireGuard Server.

For some reason with a Wireguard server running, the WAN Upload is capped at 500Mbit on IPv4. IPv6 seems not affected.

As mentioned, iPerf3 is a good way to test. I've found that I get better results when including the -w 4M option. Another method that might be easier to implement for some is to run an OpenSpeedTest server on one of your LAN devices and test against it. If memory serves me correctly my Pixel 8 Pro would do around 1400 Mbps using a 160 MHz wide channel.

Same goes for iPhone 11

No 160MHz support on this client. About 800Mbps is excellent.

Are you using a standalone router (+AP(s)?) or multiple in an AiMesh?
