WIFI card problem!! Scan works, no connect.

Hello,
I'm a brand new Linux user and I recently finished installing Arch on my Vaio Laptop. Everything is working accordingly except for my wireless card.

My Wireless Card:
Linksys WPC54GS

I originaly used only ndiswrapper but did not work, I then used bcm43xx but the link was very poor, I'd have to spam iwlist scan just to see my router.I then used bcm43xx-fwcutter to extract the firmware from bcmwl5.sys and moved it to the according directory and ndiswrapper on the inf file, this method works much better then the previous attemps.

The Wificard is visible and responds to "iwlist scan" but I am not able to connect to any of the access points using "iwconfig eth1 ap ----". I've also tried using wifi-radar but that does not work either. /etc/rc.d/network start does not work with wifi only.

Re: WIFI card problem!! Scan works, no connect.

I thought the wireless driver would automaticly connect to the Access Point with the best connection, but try:

#iwconfig eth1 essid "LMB"

To connect to the access point, and:

#dhcpcd -n eth1

To get an IP address.

> If dhcp doesn't work, try setting the IP manually (man ifconfig)

> Have you managed to connect to your router with another os/distro? It *might* be an error in the router.

> issue: ifconfig eth1 up, then request ip from dhcp, if dhcp is enabled in the router.

> Not sure how you set your iwconfig up, but don't forget to set anyhing, like channel or so. i.e.
iwconfig essid "LMB" channel 6 mode managed

Re: WIFI card problem!! Scan works, no connect.

Thankyou for your input! I'm sorry I wasn't able to respond sooner.

Okay, the other day I took my laptop to a public ap and used dhcpcd as suggested and everything worked fine! I'm still having problems connecting to the home router tho, I will try the manual IP setup and see what happens.
