Re: Setting up WiFi on PB with AirPort Extreme

Ebrahim,

A couple of things to look at;

1. Do you have a default GW assigned (typically your router)? /sbin/route -n look for some IP and the letters GW.
2. Can you ping 192.168.1.1? If so the network card is working
3. Then check /etc/resolv.conf for a nameserver entry. It will be the DNS from you isp and should look like nameserver xxx.xxx.xxx.xxx where xxx.xxx.xxx.xxx is the IP address of the DNS.

good luck
bart

Dear list

I setup my internal AirPort Extreme wireless card using the "script" shown below. I am, however, unable to send/receive e-mail or bring up web pages. Some details and diagnostics:

The KWiFiManager application shows green bars for the signal strength with the following parameter values:

Interface eth1

Connection Speed:---------------->11

Signal strength: 100

Local IP: 192.168.1.104

Frequency[channel]: 2.462[11]

Two questions concerning the setup of my Linux WiFi connection:

Q1: If I prepare a bash script of the command sequence above, where do I place the script in order to automatically activate my W-Fi connection at startup?

Q2: I cannot bring up a webpage in Firefox. I get a "Server not found" error. Why?

Comment: I cannot log out after this. I was obliged to disconnect the laptop battery in order to reboot.

Any ideas on why the wireless connection is still not working. Thanks in advance.
