I have both 5GHz and 2,4GHz wifi networks configured at home (same router, different SSID). I can connect to 5GHz without any issues with my laptop running eos, but I cannot connect to 2,4GHz network unless I use:
options iwlwifi 11n_disable=1
However, when I do this, the speed for both networks is slow (20Mbps vs. 160Mbps download speed for 5GHz).
Is this slowdown a general byproduct of using 11n_disable=1 or is it possible to somehow make my computer use 2.4GHz without speed sacrifice for 5GHz network?
What wifi speed standards do your router and your computer support?
Also, are you using the router in a place where there are several other wifi routers nearby?
I apologize for delayed answer:
- laptop: Intel Dual Band Wireless-AC 7265 supports 802.11ac standard
- same goes for my router: TP-link Archer 6
In fact, I was running both 2.4GHz and 5GHz nework on this laptop before running windows 10, so I don’t believe it’s the hardware issue
Can you show the output of this command:
I was able to finally solve this issue by using iwd as the Wi-Fi backend:
restart NetworkManager service (sudo systemctl restart NetworkManager.service)
After these steps, both my 2.4GHz and 5GHz networks are working as expected without the need to 11n_disable=1
Great that you got it working!
