well to start off, I use wpa_supplicant to connect to the internet because it's simple and for me it "just works"
when I boot up my laptop and log into my desktop environment I start up wpa_gui and I see it's already connected to the nearest network that I have saved (up to there everything works). now after a while, after associating with any wireless access point, it obtains an obscure ip address
For example, at home I have a linksys router with a gateway of 192.168.1.1 and it assigns ip address from 192.168.1.2-192.168.1.50 and I know because I set it up and it works correctly with windows and all my other wireless devices
then after wpa_gui shows that it has associated it obtains an ip address of 169.254.70.226 for example which I've read in a bunch of forums is some sort of default in the event it cannot find a dhcp server or something? a similar problem occured in this forum http://forums.gentoo.org/viewtopic-t-91 … art-0.html which might explain better
Searching though my home directory I find 2 symlinks that are highlighted red with white letters in it (don't know if that means broken symlink or normal or if it's even supposed to be there)
here I provided some pastebins to some config files to see if there's anything I could have missed
/etc/conf.d/dhcpd
http://bpaste.net/show/48742/
/etc/conf.d/ip6tables
http://bpaste.net/show/48743/
/etc/conf.d/iptables
http://bpaste.net/show/48744/
/etc/conf.d/net
http://bpaste.net/show/48745/
/etc/conf.d/net
http://bpaste.net/show/48746/
_______ and then /etc/dhcp directory
/etc/dhcp/dhclient.conf
http://bpaste.net/show/48747/
/etc/dhcp/dhcpcd.conf
http://bpaste.net/show/48748/
/etc/dhcp/dhcpd.conf
http://bpaste.net/show/48749/
I also have the dhcpcd.conf file in /etc and I don't know if that's normal
_________in /etc/init.d I have
/etc/init.d/net.eth0
http://bpaste.net/show/48751/
/etc/init.d/net.wlan0
http://bpaste.net/show/48752/
/etc/init.d/netif.lo
http://bpaste.net/show/48753/
/etc/networks
http://bpaste.net/show/48754/
Here is something REALLY weird
/etc/resolv.conf
http://bpaste.net/show/48755/
got overriden by my university's wireless apparently but it MIGHT be what's causing the problems but I'm not sure
and here is /etc/wpa_supplicant/wpa_supplicant.conf
http://bpaste.net/show/48757/
rc-update shows that I have net.eth0, net.wlan0 and netif.lo and netmount all in default run level
anything else you need let me know

Add

dhcpcd_wlan0="--nolink"
to /etc/conf.d/net. If it does not improve the situation, remove it. If it does improve the situation, remove
Quote:
dhcpcd_wlan0="--noipv4ll"

best guess: flaky NIC
Code:
grep -i CFG80211_DEFAULT_PS /usr/src/linux/.config
if you get
Quote:
CONFIG_CFG80211_DEFAULT_PS=y
changing your kernel config to
Quote:
-> Networking support (NET [=y])
-> Wireless (WIRELESS [=y])
-> cfg80211 - wireless configuration API (CFG80211 [=m]
[ ] enable powersave by default
and recompiling might help stability.
