problem: D-Links DWL-g650(A) won't connect to gateway.

distro: Slackware 10.1
kernel: 2.4.29.
drivers: prism54 latest CVS(also tried latest stable) and latest firmware (tried all firmwares).

The card used to work fine for about 2 months, but now it can't find the gateway.

dmesg doesn't show any errors. Neither does /var/log/messages and /var/log/dhcpcd.log.

I've tried changing the powerusage with `iwconfig eth0 txpower 1`. also tried `iwconfig eth0 essid X` and `iwconfig eth0 channel X`. But that used to work automatically before.

The 3com wireless gateway is correctly configured. Nothing has been changed. There is still no encryption and all MAC's are allowed.

I think i've tried everything... the card is detected and the lights are blinking when searching.

is it broken?

Did you change anything before it stopped working? Also, what are the outputs of ifconfig and iwconfig? Finally, check lsmod to see if the prism module actually loaded.

no, nothing has been changed


1. /etc/rc.d/rc.pcmcia start
2. modprobe prism54
3. ifconfig eth0 up
4. /etc/rc.d/rc.inet1 start

this is strange..... i just turned on my laptop (been off for 1 day)... now the card works!!! but for only 1min... now it's dead again... i waited 10min.... it's works again, but for 10sec... :/ heat problem?

wow.... i tried pulling and pushing the card up and down while inserted into the pcmcia slot.. what do you know, it works!!! :O

seems to be a damage on the card...

Yeah, that kind of sounds like hardware is the trouble.
