I run Debian testing on a Lenovo Thinkpad E531 which I bought in June. I have been running Debian for the last 14 years, and have used the testing stream on several machines for the last seven or eight years.
I have never used network-manager to manage my wireless connection, depending instead on my own customised interfaces file. I do not use DHCP. About three weeks back, after a dist-upgrade, my wireless connection refused to come up. I checked everything possible - routes, dns etc. There was nothing wrong with any of these parameters.. I reinstalled the wireless drivers (the card is a BCM43228), and recreated the wpa_supplicant.conf file, all to no avail. I went through the debian-user lists for September but could find nothing similar to what I had encountered. The only similar complaint was this [1] but the user appears to be utilising network-manager already. To fix my problem, I had to bite the bullet and install network-manager. My wireless connection works now. But I would rather uninstall it and go back to what I was using. Having read what is available, it looks like this is due to a problem between systemd and wpa-supplicant; an older version of wpa-supplicant seems to work well with systemd, not the latest. But this conclusion could be wrong. I have checked the debian-user lists for both September and October before posting and cannot find anyone with a problem similar to mine. Any comments would be welcome. Please copy me in as I am not subscribed to the list.
