Created attachment 1643703 [details] nmcli debug log Description of problem: I'm no longer to connect to our internal WPA2 Red Hat Wifi. Downgrading to 1.22.0-0.1.el8 works fine. Version-Release number of selected component (if applicable): NetworkManager-1.22.0-0.2.el8 How reproducible: 100% Steps to Reproduce: 1.connect to Red Hat Wifi 2. 3. Actual results: Expected results: Additional info:
hm, are you sure that 1.22.0-0.1.el8 works? That would be unexpected, but if you are sure, quite some important information. Without this piece of information I would have said this is a wpa-supplicant or driver issue... Could you also attach a level=TRACE log with a working case? Thank you.
Created attachment 1644352 [details] old nmcli debug trace Successfully connected with NetworkManager-1.22.0-0.1.el8
It seems the new internal DHCP client implementation times out when requesting a lease: [1575993447.6522] dhcp4 (wlp2s0): sent DISCOVER to 0.0.0.0 ... [1575993485.4081] dhcp4 (wlp2s0): request timed out The old client based on systemd is working well instead.
I can confirm this, if I use dhclient option with NetworkManager-1.22.0-0.2.el8, I'm able to connect. $ NetworkManager --print-config # NetworkManager configuration: /etc/NetworkManager/NetworkManager.conf (etc: 99-dhcp.conf) [main] # plugins=ifcfg-rh # rc-manager=symlink # auth-polkit=true dhcp=dhclient [logging] # backend=journal # audit=false # no-auto-default file "/var/lib/NetworkManager/no-auto-default.state"
Also, the Wi-Fi settings for wpa-supplicant differ. Which is odd... Jiri, cuould you please also show the profile in question? First, identify the file in which it is stored: nmcli -f UUID,NAME,FILENAME connection show Then, attach the corresponding file (sanitizing private data first!!). Probably it's in "/etc/sysconfig/network-scripts/ifcfg-$NAME". In that case, make sure to include all relevant "/etc/sysconfig/network-scripts/*-$NAME" files.

Created attachment 1644489 [details] nmcli debug log (In reply to Thomas Haller from comment #5) > Also, the Wi-Fi settings for wpa-supplicant differ. Which is odd... As part of debugging, I have deleted the old profile and created new one from scratch. This output is from the profile I have pasted and the same I used with the -1 build.
Hi Jiri, could you please capture packet traces when NM tries to connect, first with dhcp=internal and then with dhcp=dhclient? You can use a command like: sudo tcpdump -i any -w wifi-internal.pcap You can send the output files via email to me if you prefer. Thank you.
