So, Hi
Third install as have had the same issue 3 times.
Can log into the normal 5G home WiFi but unable to browse at all.
I have an InvizBox 2 router, separately & can log into it’s WiFi, with no issues. (shows as wlo1)
02:00.0 Realtek Semiconductor Co.,LTD RTL8852BE PCIe 802.11ax Wireless Network Controller [10ec:b852]

Not a big issue but is a tad slower than my normal home wifi.
Thanks && let me know if you need more info :slight_smile:

Welcome to the Garuda community @Blackwolf_Oz :waving_hand: :smiley:

Ensure your router has different names for the 2.4 GHz and the 5 GHz bands. Only connect on the 5 GHz band to prevent signal problems caused by repeatedly swapping between bands. Try locking your Wifi connection to your AP’s 5 GHz SSID in network manager. You can do this in Network Manager’s “Wi-Fi” tab in your WiFi connection’s properties settings.

There is a “BSSID” drop down field where you can select and lock your home Wi-Fi to a single BSSID.

Also try disabling Network Manager’s WiFi power saving features with the following command:

echo -e "[connection]\nwifi.powersave = 0" | sudo tee /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

A setting of “0” will totally disable power saving features in the WiFi adapter.

A setting of “2” or “1” will be less aggressive, but still leave power saving enabled.

Good luck with those suggestions, and again welcome to the Garuda forum.

After modifying Network Manager’s configuration, reboot both your router and your computer.
