To follow-up for other readers: I've set the bssid= option in wpa_supplicant.conf to forcibly connect to the 5GHz wireless lan. This works much better and it turns out that other devices automatically switched to the 5GHz band. I thought that leaving out the bssid option would also switch automatically but that did not work so well. I am still wondering why the 2.4GHz band is not working anymore but I don't have access to the AP itself (it looks like there are no interfering APs except this one; but perhaps, something else is causing it trouble). -- Christian Barthel <bch@online.de>
