Hi All,

I am trying to get wireless working and have hit a road block (it doesn't connect).

I am using an SMC2802w wireless nic.

I know that the NIC is working because when I run "iwlist scanning" I get the following output:
eth0 Scan completed :
Cell 01 - Address: 00:11:59:41:54:31
ESSID:"BobSacamano"

But I can't connect to my router (ESSID: BobSacamano).

When I run iwconfig, I get the following:
eth0 IEEE 802.11b/g Mode:Managed Frequency:2.432 GHz
Access Point: 00:00:00:00:00:00 Bit Rate:0 kb/s Sensitivity=20/200

and when I run ifconfig I get the following:
eth0 Link encap:Ethernet HWaddr 00:04:23:63:AA:FF

I can even ping my wireless IP adress and ssh to it (so I thought I had things working) but connection is lost when I disconnect the wired NIC.

I would really appreciate any insight into where I have gone wrong here.

Thanks again,
jpummill

are you using wep or wpa if so have you entered the 26 digit key if it's wep, if it's wpa you'll have to google for it, I've heard of people getting wpa working, but I haven't dug into it myself to figure out the details.

Ok, first problem solved. I finally had a chance to look at this today and figured out that the MAC address was wrong. Now if I can get my WEP working I should be ok.

wep should work fine just add the line

wireless_key 26digithexkeyhere

to the /etc/network/interfaces file.

If you set MAC Filtering on your router so only certain MAC addresses can connect is WEP/WPA really needed? Other than slowing down your connection it really isn't needed unless you are paying your bills, etc via that wireless computer right?

It's another layer of protection. Requiring a key creates another roadblock for ppl trying to access your AP.
