Hello I am working on a WLAN client on an embedded system and I am facing a problem using WEP. I am using the b43 driver with a BCM43222 mini-pci card and kernel 3.10.55. The card works fine with WPA and without encryption. Using WEP results in a weird situation where dhcp requests can be sent across the wireless link, but a dhcp reply is never received. The only error I could come up with is AP# ip link set wlan0 up AP# iw event -f & AP# iw wlan0 connect scoobly keys 0:abcdefghijklm wlan0 (phy #0): scan started AP# wlan0 (phy #0): scan finished: 2412 2417 2422 2427 2432 2437 2442 2447 2452 2457 2462 2467 2472 2484, "scoobly" wlan0: new station f8:1a:67:56:42:96 [ 417.886167] b43 ssb0:0 wlan0: failed to set key 0 wlan0 (phy #0): auth f8:1a:67:56:42:96 -> 00:1a:2b:5f:61:11 status: 0: Successful [frame: b0 00 40 01 00 1a 2b 5f 61 11 f8 1a 67 56 42 96 f8 1a 67 56 42 96 00 00 00 00 02 00 00 00] wlan0 (phy #0): assoc f8:1a:67:56:42:96 -> 00:1a:2b:5f:61:11 status: 0: Successful [frame: 10 00 40 01 00 1a 2b 5f 61 11 f8 1a 67 56 42 96 f8 1a 67 56 42 96 10 00 31 04 00 00 01 c0 01 08 82 84 8b 0c 12 96 18 24 32 04 30 48 60 6c dd 18 00 50 f2 02 01 01 85 00 03 a4 00 00 27 a4 00 00 42 43 5e 00 62 32 2f 00 dd 09 00 03 7f 01 01 00 00 ff 7f dd 0a 00 03 7f 04 01 00 06 00 40 00] wlan0 (phy #0): connected to f8:1a:67:56:42:96 AP# tcpdump -i wlan0 -s 1500 -w /tmp/foo & AP# tcpdump: WARNING: wlan0: no IPv4 address assigned tcpdump: listening on wlan0, link-type EN10MB (Ethernet), capture size 1500 bytes AP# dhcpcd wlan0 dhcpcd[4335]: version 5.2.11 starting dhcpcd[4335]: wlan0: broadcasting for a lease dhcpcd[4335]: timed out AP# tcpdump -r /tmp/foo reading from file /tmp/foo, link-type EN10MB (Ethernet) 08:49:56.270834 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:1a:2b:5f:61:11 (oui Unknown), length 314 08:50:00.395859 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:1a:2b:5f:61:11 (oui Unknown), length 314 08:50:07.559542 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:1a:2b:5f:61:11 (oui Unknown), length 314 08:50:22.958262 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:1a:2b:5f:61:11 (oui Unknown), length 314 AP# iw dev wlan0 link Connected to f8:1a:67:56:42:96 (on wlan0) SSID: scoobly freq: 2427 RX: 537892 bytes (7445 packets) TX: 3639 bytes (21 packets) signal: -76 dBm tx bitrate: 1.0 MBit/s bss flags: short-preamble short-slot-time dtim period: 0 beacon int: 100 The dhcp request is received at the dhcp server and is being answered to.
