Slow Wi-Fi on Zorin OS 18 Core

The Issue

Speedtest.net results for my PC are 7.07 Mbps download and 2.75 Mbps upload with idle latency of 20, download latency of 524, and upload latency of 54 (all in ms).

On an iPhone (from roughly the same location) I have 490 Mbps download and 11.2 Mbps upload with idle latency of 51, download latency of 145, and upload latency of 48 (all in ms).

What I've Tried/Checked

It should be noted that there seems to have been several UI changes/file name changes that rendered a lot of previous advice/troubleshooting tips difficult to follow. As such, there may have been execution failures of some things on my end.

  1. Turning off the powersaving by changing the value wifi.powersave = 3 to wifi.powersave = 2 (and also to 1). I restarted the PC after these changes and double checked the config had been successfully updated by reopening the file.

  1. Disabling IPv6

  2. Disabling metered connections.

  3. Opening in "Wayland" mode in the user login screen.

I am wondering if it is defaulting to 5 GHz channel. Whilst 5 GHz is faster it is not as stable as 2.4 GHz (it has difficulty transmitting through walls etc.). Can you disable 5 GHz at the modem/router?

The downside to 2.4 GHz occurs if you have Energy Smart Meters which transmit on the same frequency of 2.4 GHz which can interfere with wifi.

Welcome to the Forum!

I would suggest to try it with going back to an older Kernel. To do that, choose on the GRUB Menu the Option ''Advanced Options''and choose there an older Kernel to start with.

No se trata de eso , leiste lo que cuenta el usuario dice que el esta sentado en la misma mesa con su telefono y le da 490 Mb/s o algo similar y 11.2 mb/s upload asi que no son las paredes le llega bien tiene que ser otra cosa para mi creo que es el driver como yo he tenido dificultad pero lo aregle como pues es secreto y lo resolvi con la ayuda de una IA hizo un driver encontrado por ahi lo integre y ahora tengo mi propria libreria en gitHUB va te mostrare no me cuesta nada GitHub - bogdansaniuta/BE6500-Zorin-WIFI7-Driver: Driver experimental para WiFi 7 BE6500 en Zorin OS (basado en rtw89) · GitHub y recuerda no son las paredes jejejeje es el driver supongo pero debera tener este producto si quere hacerlo funccionar en zorin os 18.1 pro en la final de la pagina de gitHUB vera el producto y si lo busca por amazon o PCcomponentes en espeña tambien se puede comprar y estoy super feliz.

But Your Driver an't help here because the Wifi uses an Intel Chip:
