I'm running Sid on my ThinkPad X200s, and after an `aptitude upgrade` the WiFi is experiencing intermittent problems. Pretty sure it's not the hardware, as I've never experienced these issues before and this started happening exactly after the upgrade.
It's an Intel Ultimate N 5300 WiFi card: % lspci | grep WiFi 03:00.0 Network controller: Intel Corporation Ultimate N WiFi Link 5300 Sometimes it works: % iwconfig lo no wireless extensions. eth0 no wireless extensions. wlan0 IEEE 802.11abgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off % rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no Sometimes it doesn't work: % iwconfig lo no wireless extensions. eth0 no wireless extensions. % sudo iwconfig wlan0 txpower on ; sudo ifup wlan0 Error for wireless request "Set Tx Power" (8B27) : GET failed on device wlan0 ; No such device.

Any suggestions regarding how to get WiFi working again would be much appreciated.
