Bridged networking problem | no ip address

[Galois]

Hi all,

I have a networking issue. My guests doesn't receive an IP address in bridged mode (over wifi). I'll show my logs

My Host: Kubuntu 18.04, kernel: 4.18.0-25-generic
Tested on VirtualBox 6.0.10r132072 and 5.2.18. (Of course, i had done a clean install before I've tested it )
Guests and tested in:
Windows 10 1903 (OS Build 18362.239)
Windows 7 7601
CentOS 7 3.10.0-957.21.3.el7.x86_64
Debian 10 4.19.0-5-amd64
And several BDS'

Last update: What did I discover? If I am connected to a 5 MHZ Wi-Fi, I don't receive any ip address. But I'll receive an ip address, if i am connected to 2.5 MHZ Wifi. Nat works well.

Hope you can help.

Then stick with that. Easy...

Bridged over WiFi doesn't always play nice. Bridged networking is outside the WiFi specification. It may or may not work. If it works on some of them, it's because the manufacturer chose to ignore the specification. Some combinations of Routers/Access Points, WLAN cards and drivers work, some don't.
