Hello community,

i got the problem on my acer aspire 575g that i cannot connect to the wifi @ my school which has a mac filter on. It first asks me a few times to type in the password and after a while i kinda connect but no internet access, it just shows a questionmark. I already tried to create the file "/etc/NetworkManager/conf.d/100-disable-wifi-mac-randomization.conf" with the content:

[connection]

wifi.mac-address-randomization=1

[device]

wifi.scan-rand-mac-address=no

But without luck, still can't connect. This is happening on any linux distro, tried ubuntu, debian, fedora, suse. THO! The wifi connection works on Windows 10. This is so weird, maybe there is a driver problem?(Qualcomm Atheros QCA9377)

I really need help here!

You shouldn't need that file. The first option I think is wrong anyway and deprecated. The second option should be unnecessary because it only uses random mac addresses for scanning, not for connecting. Have you checked that the mac address is the same in windows and Fedora?

yep, it's the same mac-address in windows and linux. I tried connecting to the network with the laptop of a friend (has the same one as me) and it didn't work either. Others with linux can connect to the network.

Do you remember if there's a captive portal on that Wifi? It'll be like a page that loads with a consent-to-monitor banner/payment. Well if one of those are setup, it's quite possible that you're connected to the network yet have no internet access because you haven't consented. Usually, Admins will intercept DNS requests and automatically redirect you to that page. Windows devices will automatically call out to the following domains to test connectivity after a network change: http://www.msftconnecttest.com/redirect (Windows 10) or http://www.msftncsi.com/ncsi.txt (Windows 8.1 and earlier). It is common for network admins to check for these connections and redirect you to where you need to go.

What you should do is connect to their Wifi, then open up a browser and navigate to either of those two domains. There's a good chance that you'll be redirected to the captive portal page you need to successfully gain access to the network. Then you should be good.
