Wireless w/ ndiswrapper; fails to get ip from dhcp

Abecedarian · 2006-08-28 05:16:19

I've got a DWL-G510 and I recently used ndiswrapper to install the win2k drivers. It confirms 'driver installed, hardware present', iwlist can scan and pick up my access point, put in the WEP key, and associate the access point successfully (It comes up with the MAC Address of the router). However, then I go the old

ifconfig wlan0 up
dhcpcd wlan0

and it fails to receive an IP; it just sits there for a few minutes, does nothing, and downs the interface in ifconfig. And yes, DHCP is set up, as ethernet connections work fine. The wireless also works in windows, so it's not with that either. Is there any step that I've missed? (Yes, I've read the ndiswrapper installation wiki page)

what's the output of iwconfig?

also, post the output of "iwlist wlan0 scan" please

I boot:

[root@archbox tom]# ifconfig

I modprobe ndiswrapper and scan the networks:

[root@archbox tom]# iwlist wlan0 scan

I associate the access point:

[root@archbox tom]# iwconfig wlan0 key ########## essid homewlan

I check to make sure it's configured fine:

[root@archbox tom]# iwconfig

I dhcp it:

[root@archbox tom]# dhcpcd wlan0

ifconfig then returns to its initial state (ie. without wlan0 as active).

You forgot

iwconfig wlan0 essid homewlan

dont waste your time using ndiswrapper, theres a reasonable chance it's supported by a native driver.

Googlin shows that theres been a few revisions of this, it might be a good idea for you to post the lspci -vv output so we can identify which chipset it uses.

From madwifi's page, it says that it uses atheros, supported with the 'madwifi' driver in the repos. pacman -S madwifi
http://madwifi.org/wiki/Compatibility#DWLG510

Also mentions ralink, which would mean the rt2x00 series, which is constantly improving, and worth giving a shot, it's in unstable 'rt2x00'. If you dont have any luck with that, get the older driver from their site, but beware that some of them do not support as much, or crash on SMP. (rt2500 and rt2600 are fine afaik)
