I have been having a "flaky" connection with my wireless. I have the same laptop as my co-workers and they have not been having an issue, so I know it is not a question of wireless strength.
My setup:
ThinkPad T43
Slackware 10.2
2.6.15 RC 2 kernel
ipw2200 drivers
wpa_supplicant 0.4.7
What happens (problems):
- I often get a timeout during if up (I have to restart my eth0 several times on occassion for dhcpd to be able to get an IP address)
- My signal strength, usually around 90% will drop to 0% for sometimes around a second, sometimes much longer.
I haven't been able to find out why (I am not too familiar with wireless on linux enough to determine how to debug well).
This problem happens when I am in a WEP environment and in a WPA environment
When my signal strength is 0, here is the iwconfig output:
Code:
eth0 unassociated ESSID:"..." Nickname:"..."
Mode:Managed Channel=0 Access Point: xx:xx:xx:xx:xx:xx
Bit Rate=0 kb/s Tx-Power=20 dBm
Retry limit:7 RTS thr:off Fragment thr:off
Encryption key:... Security mode:open
Power Management:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
Here is the setup of my card:
/etc/wpa_supplicant.conf
Code:
#ctrl_interface=/var/run/wpa_supplicant
#ctrl_interface_group=wheel
#eapol_version=1
#ap_scan=2
#fast_reauth=1
network={
ssid="..."
key_mgmt=NONE
auth_alg=OPEN
wep_key0=...
wep_tx_keyidx=0
priority=5
}
network={
ssid="..."
psk=...
}
/etc/rc.d/rc.inet1.conf:
Code:
# Config information for eth0:
IPADDR[0]=""
NETMASK[0]=""
USE_DHCP[0]="yes"
DHCP_HOSTNAME[0]="..."
WLAN_WPA[0]="wpa_supplicant"
One of my co-workers is on Debian with the same Kernel, and same ipw2200 drivers but does not use wpa_supplicant and has not issues.
Any idea on what the problem is or at least suggestions on how to debug it?
