Mac Forum / General / General / May 2008Side by side, but they behave differently..
I have described this problem before in this newsgroup, but it is still baffling me: I have two G4s which each has an Airport Extreme card fitted. Both suffer from the same problem, tho' the one, an iBook far more than the other, an aluminium Powerbool. The problem is that when started up, the don'r receive an IP address from my Netgear wireless modem router, and so self-assign one which means I can't get onto the net. Now the iBook does this far more than the Powerbook and is, in fact doing so right at this moment. Both were fired up at the same time, the Powerbook gets an IP address and connects to the net, the iBook doesn't. Why not? Before it has been suggested that there was something wrong with the Netgear wireless modem, but that can't be the case. Both laptops as sitting side by side as I write, one connected one not. Please, someone help me out.

PP The first thing I would do is take a look at the system and console logs to see if any network-relevant errors are logged there. What happens if you turn Airport off and back on? Does it automatically connect then?  SignaturePlease send all responses to the relevant news group. E-mail sent to this address may be devoured by my very hungry SPAM filter.

Why not? Did you tell us anything the first time about which Mac OS version you're running and whether it's the same on both? Did you tell us specifically which Netgear router model you're using, whether you've updated it to the latest available firmware, and whether you've tried resetting it? > Before it has been suggested that there was something wrong with the > Netgear wireless modem, but that can't be the case. And you've ruled that out how exactly? By trying both Macs with a different router and determining that the problem exists with that router, too? By updating the firmware and resetting it?

This doesn't mean that you personally need to get your hands on another router to test it. You can bring both laptops to a location with public wifi access. If they're fine there, I'd strongly suspect your Netgear.

Both laptops as sitting side by side as I write, one > connected one not. Please, someone help me out. PP I would try assigning a fixed IP address to the iBook. To do this right, you need to know what IP addresses are valid in your network and what addresses can be handed out by your router. If you can't figure that out, you can make some educated guesses. Check System Preferences -> Network and look at IP Address, Subnet Mask, and Router on the Powerbook (when it successfully connects to the net). Let us know what those numbers are. In the meantime, you can try assigning an address to your iBook that is somewhere between the iBook's IP Address and Router address. If you pick the wrong one, it might cause problems in the future, but you might get away with it for a long time. Before you actually assign a fixed IP address to your iBook, use the Network Utility to ping the selected address and make sure you don't get any return packets. If you do, pick another address and try ping again.

I forgot to add that you should copy the Subnet Mask, Router, and DNS Server entries from the one that is working to the one you are assigning a fixed address. SignatureJim Gibson |
