Package: iw Version: 3.17-1 Severity: important Dear Maintainer,
My network manager (wicd) lost the ability to connect to my unsecured wireless router when I upgraded from the 3.16-0-4-686-pae kernel to the 4.1.0-1-686-pae kernel. It still works normally when I boot into the 3.16 kernel. This computer has a Qualcomm Atheros wireless adapter using the ath5k driver. See further details in the command line output below. On another computer of mine, wicd lost the ability to connect when upgrading from the 4.0.0-2-686-pae to the 4.1.0-1-686-pae kernel. (On this computer -- the one I'm preparing this bug report on -- I upgraded directly from the 3.16 kernel to the 4.1 kernel, so have not tested the wireless connection on this computer when running the 4.0 kernel.) On that other computer -- the one on which I lost wireless capability on the upgrade from the 4.0 to the 4.1 kernel -- I have an Intel Ultimate N Wifi Link 5300 adapter using the iwlwifi driver. Since I have the same problem with two different devices, I assume this problem is not specific to a particular adapter or driver. Sorry if I'm reporting this bug against the wrong package. From the command line I can't connect using either the iw or the iwconfig utilities, and I don't know how to narrow the problem down any further. Below are a series of commands that I ran under both the 3.16 and the 4.1 kernel with the corresponding terminal output, showing that both the iw and iwconfig commands successfully connect when running the 3.16 but fail when running the 4.1 kernel: _______________________________________________ OUTPUT WHEN RUNNING THE 3.16 KERNEL: root@kitchencomp:/home# lspci -k <part of output omitted> 00:0d.0 Ethernet controller: Qualcomm Atheros AR5212/5213/2414 Wireless Network Adapter (rev 01) Subsystem: D-Link System Inc AirPlus DWL-G520 Wireless PCI Adapter (rev.
