Hey 🙂
Since 1h, i'm facing a weird problem : My laptop refuse to connect to the 5Ghz wifi. The 2.4 works. I'm a beginner, and i can't find easy step to diagnose and maybe reset my driver...My phone connect on it (5Ghz), and my wife's laptop connect on it.
Network:
Device-1: Intel Cannon Lake PCH CNVi WiFi driver: iwlwifi
IF: wlp0s20f3 state: up mac: 44:af:28:7e:29:f8
Device-2: Realtek RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet
driver: r8169
IF: enp7s0 state: down mac: 8c:8c:aa:17:ac:54
I think it's not my wifi card because i can connect on the 2.4 band.
