Hi! I've been trying to help a friend out with wireless on his Thinkpad X220. The identifier is:
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01) Now, according to http://wiki.debian.org/rtl819x the drivers should work for the kernel (2.6.39 bpo.2). However, while wlan0 is displayed, he is unable to configure his network, and dmesg output says this: [ 2069.228798] rtl8192ce 0000:03:00.0: PCI INT A disabled [ 2085.887165] ieee80211_crypt: unregistered algorithm 'WEP' [ 2085.887174] ieee80211_crypt: unregistered algorithm 'CCMP' [ 2085.887181] ieee80211_crypt: unregistered algorithm 'TKIP' [ 2085.887187] ieee80211_crypt: unregistered algorithm 'NULL' (deinit) [ 2143.973876] ieee80211_crypt: registered algorithm 'NULL' [ 2143.973885] ieee80211_crypt: registered algorithm 'TKIP' [ 2143.973892] ieee80211_crypt: registered algorithm 'CCMP' [ 2143.973898] ieee80211_crypt: registered algorithm 'WEP' [ 2143.973921] [ 2143.973923] Linux kernel driver for RTL8192 based WLAN cards [ 2143.973929] Copyright (c) 2007-2008, Realsil Wlan [ 2326.698887] ieee80211_crypt: unregistered algorithm 'WEP' [ 2326.698897] ieee80211_crypt: unregistered algorithm 'CCMP' [ 2326.698904] ieee80211_crypt: unregistered algorithm 'TKIP' [ 2326.698910] ieee80211_crypt: unregistered algorithm 'NULL' (deinit) [ 2343.256604] rtl8192ce 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 [ 2343.256624] rtl8192ce 0000:03:00.0: setting latency timer to 64 [ 2343.266633] ieee80211 phy1: Selected rate control algorithm 'rtl_rc' [ 2343.267260] rtlwifi: wireless switch is off In spite of having switched the WiFi on, Network Manager doesn't see anything. iwlist scanning gives: Failed to read scan data : Network is down Also, rfkill showed: 2: phy0: Wireless LAN Soft blocked: yes Hard blocked: no An rfkill unblock removed the soft block, but that still did nothing. I've run out of debugging ideas, and am looking for suggestions. Could you let me know how I should go about this? Thanks! Kumar -- Sigh. I like to think it's just the Linux people who want to be on the "leading edge" so bad they walk right off the precipice. -- Craig E.
