I agree with the problem being related to WPA. On a dual boot Windows XP Pro & Ubuntu Gutsy Dell Latitude D830 machine, using the Intel 3945, connecting to a Watchguard Firebox e10-w, I have no problems connecting with WPA on Windows, but get many dropped "ping" packets when in Ubuntu. For example, pinging my default gateway gives me:
[EMAIL PROTECTED]:/etc# ping 192.168.20.1 PING 192.168.20.1 (192.168.20.1) 56(84) bytes of data. 64 bytes from 192.168.20.1: icmp_seq=1 ttl=64 time=1.63 ms 64 bytes from 192.168.20.1: icmp_seq=2 ttl=64 time=1.62 ms 64 bytes from 192.168.20.1: icmp_seq=3 ttl=64 time=1.60 ms 64 bytes from 192.168.20.1: icmp_seq=4 ttl=64 time=1.50 ms 64 bytes from 192.168.20.1: icmp_seq=5 ttl=64 time=1.75 ms 64 bytes from 192.168.20.1: icmp_seq=6 ttl=64 time=1.66 ms 64 bytes from 192.168.20.1: icmp_seq=7 ttl=64 time=1.36 ms 64 bytes from 192.168.20.1: icmp_seq=8 ttl=64 time=1.63 ms 64 bytes from 192.168.20.1: icmp_seq=9 ttl=64 time=2.14 ms 64 bytes from 192.168.20.1: icmp_seq=12 ttl=64 time=2.63 ms --- 192.168.20.1 ping statistics --- 13 packets transmitted, 10 received, 23% packet loss, time 12001ms rtt min/avg/max/mdev = 1.361/1.755/2.634/0.352 ms If I turn WPA off, I get no dropped packets. I'm running kernel 2.6.22-14-generic, WPA_SUPPLICANT 0.60+0.58-0Ubuntu, and have set the mode using iwpriv set_mode to 4 and 2, (changing the Watchguard to match) as well as changing the power using "iwpriv set_power 1". I've configured the network with network manager and manually, with slightly better results setting manually, but still a 20%+ rate of dropped packets. My /etc/network/interfaces file is shown here: [EMAIL PROTECTED]:/etc/network# more interfaces auto lo iface lo inet loopback auto eth1 iface eth1 inet static address 192.168.20.99 gateway 192.168.20.1 dns-nameservers 192.168.20.1 netmask 255.255.255.0 wpa-driver wext wpa-ssid homer wpa-ap-scan 1 wpa-proto WPA wpa-pairwise TKIP wpa-group TKIP wpa-key-mgmt WPA-PSK wpa-psk 8e46a434f28a43547d2f32836a6d9b2ec46c37b18470db3d8fc64bdc89692c74 I've tried WPA(1), WPA(2), both with TKIP and AES. All result in dropped packets of more than 20%. Again, this whole setup works fine when the system is booted into Windows, or if I'm not using any authentication or encryption. So, it appears to me that there is clearly a bug somewhere. -- ipw3945 Wifi connection is very slow https://bugs.launchpad.net/bugs/103210 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
