I had an old router that worked pretty well with other pc's but in Mac OS (using itlwm/airportitlwm) the speed was about half for some reason.

If you have another router try it and check the speed.

@amirgi73 @johnpapad24 Have you tried disabling IPv6? (See #805)

It's known issue in Ventura, see #799 #823 #830.

It's the same with another Router! My primary is TL-MR6400 with OpenWrt and the secound one is a Huawei TD-LTE with stock firmware...

@amirgi73 @johnpapad24 Have you tried disabling IPv6? (See #805)

disabling IPv6 won't help. (setting ipv6 to local link only in Mac os settings and/or disabling ipv6 completly in my reouter)

[johnpapad24]

@usr-sse2 testing was done using Mac OS Catalina back then.

Your Wi-Fi is running in 802.11n 2.4GHz mode, so that might be the expected result. Does it differ a lot when compared with other OSes?

Yes it does differ alot! The is speed 1/3 or even 1/4 compared with linux or windows

-novht: Disables 802.11AC support
-noht40: Disables 40MHz when using 2.4GHz (Use this option if the network with this config causes instabilities. BRCM cards disable 2.4GHz HT40 by default)

try to add this in boot-args. it helped me. even with only -novht it performs well (77 mbps vs 7 mbps)

-novht
-noht40

Now the RS version is merged, please test.

I have the exact same problem , in windows/ Linux the speed is 150 mbs WiFi 600-700 mbs Ethernet , in Ventura 16-17 mbps WiFi max 100 mbps Ethernet

[zxystd]

@cyrushaze try this version to see if it can improve wifi performance?
