Hello all,

I'm using a Centrino 6205 wireless NIC, and can't seem to find any networks. After installing the appropriate firmware, I am able to see the NIC in the ifconfig output:

Code:

# ifconfig -a
*SNIP*
wlp3s0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 10:0b:a9:c1:51:98  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0


However, when I try to use it in WICD, I just see "No wireless networks found." Also, when I look at 'iwconfig' I see:

Code:

# iwconfig
enp0s25   no wireless extensions.

lo        no wireless extensions.

wlp3s0    no wireless extensions.


Here's what I see in dmesg:

Code:

# dmesg | grep iwl

Any suggestions on how to continue troubleshooting?

Thank you!

last time I played with a Centrino6205 it needed
Code:
grep -i wext /usr/src/linux/.config

Quote:
CONFIG_WEXT_CORE=y
CONFIG_WEXT_PROC=y
CONFIG_WEXT_PRIV=y
CONFIG_CFG80211_WEXT=y


in menuconfig as
Quote:
-*- Networking support --->
-*- Wireless --->
<M> Generic IEEE 802.11 Networking Stack (mac80211)

then new kernel compiled and saved and reboot to it
or
make modules_install and modprobe -r cfg80211 and modprobe cfg80211 and restart wicd

Thank you very much, DONAHUE; that did it. I didn't have WEXT support in my kernel.

Cheers,
Nathan Zachary
