Hi,
I also have a linksys: mine is a WAG354G. I'm also using WEP, almost
from the days of kernel 2.6.18. These days the bcm driver was so bad
that WPA was not usable, and I haven't tried recently. WEP instead
worked almost always for me.
Anyway, on my router configuration I have:
Basic Wireless Setup:
Wireless Network Mode: Mixed
Wireless Network Name(SSID): CASA
Wireless Channel: 3 - 2.422 GHz
Wireless SSID Broadcast: Enabled
Wireless Security:
Security Mode: WEP
Default Transmit Key: 1
WEP Encryption: 128 bits (26 hex digits)
Key 1: [26 hex digits, without
'0x' prefix]
Then, on the PC, if I do a:
# ifconfig wlan0 up
# iwconfig wlan0 enc on channel 3 key (x) essid CASA
(x) [same 26 digits as above, without '0x' prefix]
(casa means 'home' in italian, original, don't you think? :-))
# ifconfig wlan0 192.168.1.13 up
Some simple hints to troubleshoot it are:
- try configuring the device by hand, with the commands above, and
playing a bit with iwconfig options.
- try first with a static IP.
- if doesn't work, try:
# ifconfig wlan0 down ;rmmod `lsmod | fgrep bcm`
then redo the configuration. Sometimes reloading the driver does the
trick.
Configuration with system-config-network is very simple: in the
wireless settings tab I have:
Mode: Managed
SSID: Specified: CASA
Key: [same 26 hex digits, WITH 0x prefix!]
For the record, lspci -nn tells me this about my wireless card:
02:02.0 Network controller [0280]: Broadcom Corporation BCM4318 \
[AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] \
(rev 02)
Not a solution, I guess... but I hope this somehow helps!
