Description Slow Network Speed compared With ethernet from the same Modem. I'm using a 2.5 GHz network as my Modem doesn't support 5GHz. Speed Test using Wifi: https://www.speedtest.net/result/14044564420 Speed Test using Ethernet: https://www.speedtest.net/result/14044550925 I've tried using Airportitlwm kext with no luck! (Wifi icon appears but it won't find any newtworks to connect to, and shows scanning...)

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 https://github.com/OpenIntelWireless/itlwm/issues/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)
@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)
same isssue and i fix buy -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
@cyrushaze try this version to see if it can improve wifi performance? Ventura.zip
I try it , an are result is the same, some times great speed an some times dog shite ,its driving me bananas
I thought I had problems with the kext, tried -novht, -noht40, and disabling ipv6. No luck. Found out it was a DNS problem, changed it to 8.8.8.8 and now it works fine. If you're experiencing network slowdowns, check your DNS first.
