Things are partially solved by updating the firmware on the router. But I'm still have trouble at start up. DHCP on startup reports that it has successfully got the IP address for wlan0, but ifconfig (I added some points in rc5.d to log ifconfig) reports no IP address until the init.d hits the start script for postfix when ifconfig shows the address above. This causes problems with postfix and fetchmail starting up. To resolve the IP address I need to
ifdown wlan0 ifdown lo rcfetchmail stop rcpostfix stop ifup wlan0 ifup lo rcpostfix start rcfetchmail start
Once done everything works ok.
Any ideas why the IP Address is not getting set at startup correctly?

I'm having some strange problems with my networking..
First some info. I have a Belkin F5D5070 USB 11g which appears to be working perfectly with linuxant's driverloader behind a Dlink DSL-G604T router. But for some reason I'm having 2 problems.
1st is that on boot ifconfig shows wlan0 Link encap:Ethernet HWaddr <NIC MAC> inet6 addr: fe80::230:bdff:feaf:1a5c/64 Scope:Link UP BROADCAST NOTRAILERS RUNNING MULTICAST MTU:1500 Metric:1 RX packets:6 errors:0 dropped:0 overruns:0 frame:0 TX packets:13 errors:2 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1720 (1.6 Kb) TX bytes:2176 (2.1 Kb)
even though I have USE_IPV6="no" in /etc/sysconfig/network/config
Looking at the DHCP info file I can see that it does indeed get an ipv4 IP address /var/lib/dhcpcd/dhcpcd-wlan0.info contains the following ipv4 info IPADDR=192.168.1.3 NETMASK=255.255.255.0 NETWORK=192.168.1.0 BROADCAST=192.168.1.255 GATEWAY=192.168.1.1 HOSTNAME='zeus' DNS=192.168.1.1 DHCPSID=192.168.1.1 DHCPGIADDR=0.0.0.0 DHCPSIADDR=0.0.0.0 DHCPCHADDR=<NIC MAC> DHCPSHADDR=<ROUTER MAC> DHCPSNAME='' LEASETIME=3600 RENEWALTIME=1800 REBINDTIME=3150 INTERFACE='wlan0' CLASSID='Linux 2.6.8-24.5-default i686' CLIENTID=<NIC MAC>
Performing an "ifdown wlan0 ; ifup wlan0" appears to fix this. Why doesn't this work at start up?
Next problem I have is ipv6 in general. Having looked at lots of mails on the subject I see that some routers don't like ipv6 DNS requests. I can see this is a problem for me as YOU and Firefox both have problems resolving names. I can fix this on firefox in the about:config page - but how to fix for YOU.
I did try the 9.1 fix which was to update /etc/modprobe.conf with "install ipv6 /bin/true" which does prevent the ipv6 module from loading but also kills my network configuration - in particular neither the loopback or wlan0 get IP addresses despite the dhcpcd info file remaining as above for wlan0. Forcing a static IP configuration has no affect and ifconfig continues to show:
wlan0 Link encap:Ethernet HWaddr <NIC MAC> inet addr:192.168.1.3 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST NOTRAILERS RUNNING MULTICAST MTU:1500 Metric:1 RX packets:15 errors:0 dropped:0 overruns:0 frame:0 TX packets:24 errors:7 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3875 (3.7 Kb) TX bytes:4317 (4.2 Kb)
At this stage - things are getting very annoying and I've run out of options. I can't use YOU because of ipv6 and I can't appear to turn off ipv6 without disabling my networking. Any help would be greatly appreciated.
Also - FYI I've configured the router with no security - a risk I know, but this just keeps things simpler until I get this working.
TIA -RikD
