IP address starting with 172

[stroked]

I just started a new job at a trucking company, and I'm having problems connecting to their wi fi. My 1.33 Ghz iBook will not connect to the internet, even though it has four bars. My older tiBook will connect, although it shows no bars on the wi fi. This would be ok, but it is real slow with it's weak signal. They both have an IP address starting with 172. I haven't ever seen this before. A good connection has always started with 192. Can someone help? I would like to use my iBook, when I'm at a terminal.

The 172 class of IP is just another private class, just like 192.168.x.x and 10.x.x.x. That should have no bearing on your connectivity. You might want to check your DNS settings and verify that they are correct for the network you're on.

Can you explain how to do this? Both laptops look the same to me.

You need to check with the network administrator and see if your DNS settings are correct. Do you know if the DNS is static or dynamic? And is your computer set up to match the routers settings?

I doubt if the network administrator is here on the weekend, and if he would even care if a driver with an old mac couldn't connect. My iBook should be able to connect easier than my tiBook. The iBook has Airport Extreme verses the tiBook's Express.

Network protocols are exactly the same regardless of operating system or device. Can your laptop connect to other wireless networks and get to the Internet?

It's also possible your work is using MAC address filtering and you may need to have the MAC address of this laptop added to the list with your network administrator.

Yes it connects to other wi fi networks, including the one at their motel, but not at their terminal. If they have MAC address filtering, then why can my other Mac connect, without being added to the list? This is an open network, for any employee to use.

I'm not saying they are using MAC address filtering; how would I know anyway? I am merely showing a possibility.

You'll have to contact your network administrator and let him help you.

My solution, put the powerbook in target disk mode, and restarted iBook with the Powerbooks HDD. Now I have fast internet.

A few days ago, when I started driving again, I told my co-driver, that my laptops were so old that I needed two.

Sandbox, thanks for trying to help me.
