I am experiencing difficulties with an Intel wifi module installed in a second-hand X230 Lenovo laptop and may need your help to make it work. I'm using 11.2-STABLE (revison 339256), wlan-related modules are linked in kernel, I flashed the latest Lenovo firmware, the device is enabled in the BIOS, hardware switch is on the "on" position, and the antena led is lighted. Identification: # lspci -nn | grep Centri 03:00.0 Network controller [0280]: Intel Corporation Centrino Wireless-N 2200 [8086:0891] (rev c4) Loading the iwn module yields: # kldload /boot/kernel/iwn*fw.ko # kldload if_iwn # dmesg | grep Centri iwn0: <Intel(R) Centrino(R) Wireless-N 2200 BGN> mem 0xf1c00000-0xf1c01fff irq 17 at device 0.0 on pci2 # sysctl net.wlan.devices net.wlan.devices: iwn0 At that point all looks good, however the expected clonable wlan0 network interface is not created: # ifconfig | grep flags em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 vboxnet0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 Is this device actually supported? If it is, what could be the curlpit? If it is not, could you recommend a replacement supported PCIe module? -- %!PS -- Bertrand Petit /D{def}def/E{exch}D/G{get}D/I{2 div}D/U{dup}D/L{roll}D/Y{setgray}D/N{newpath}D /O{N 0 0 moveto}D/P{pop}D/T{translate}D currentpagedevice/PageSize G U 0 G/w E D 1 G /h E D w I h I T 0 Y 1 setlinewidth 0 1 2 { P 120 rotate 2 4 w U mul h U mul add sqrt I 50 add {N 50 0 3 2 L 0 360 arc stroke}for}for/s{O true charpath pathbbox exch 4 -1 L E sub I 3 1 L sub I} D /l(bp)D 0.94 Y /Helvetica findfont 22 scalefont setfont l s P(x)s exch P T O l show showpage
