This bug persists with wireless-tools 29.pre22. This is a softmac bug, with a simple workaround: don't attempt to set the ESSID before bringing the interface up. Subject: Re: ESSID truncated sometimes
This workaround cannot be used with DHCP.

I suggest you use a DHCP client that doesn't mess with interface state (e.g. http://dhcpcd.berlios.de/) DHCP clients that bring the interface down will cause you other problems even if this bug gets fixed. Such clients are not compatible with softmac-based drivers and a few others. >------- Comment #4 from dsd@gentoo.org 2007-07-02 12:08 ------- >I suggest you use a DHCP client that doesn't mess with interface state (e.g. >http://dhcpcd.berlios.de/) > >DHCP clients that bring the interface down will cause you other problems even >if this bug gets fixed.

Well, indeed I have random system bug when Internet ceases to work and pinging my router (192.168.0.1) produces something like "Network unreachable" error. I'm lost what's its cause. I hope that these network hangings will disappear as soon as truncated ESSID bug will be fixed.

Make sure you use a DHCP client which also doesn't bring the interface down, otherwise this will cause you problems (including the truncated ESSID) > Well, indeed I have random system bug when Internet ceases to work and > pinging > my router (192.168.0.1) produces something like "Network unreachable" error. > I'm lost what's its cause.

Use the workaround: always bring the interface up before using it, and don't use any software which brings it down. >the workaround: always bring the interface up before using it, and don't use

OK, it works with this workaround. Here is the real example of working /etc/interfaces for a DHCP managed zd1211 wireless network card:
iface eth0 inet manual
up ifconfig eth0 up
up iwconfig eth0 essid default mode Managed ap 00:C0:02:0A:C7:3E
up dhclient eth0
pre-up iptables-restore < /etc/iptables.up.rules
This requirement will persist in mac80211-based driver as well. |
