My B&W is behind a router which is sharing the internet between my three computers. Prior to 10.3.2, this setup was working just fine. The internet now no longer works on the system I upgraded to 10.3.2. Any suggestions? I've tried restarting several times, turning off AppleTalk and fire sharing, DHCP renew...nothing seems to work.

[Seamus]

OK, I've been playing around with this some more...even when I directly connect the cable modem to the computer, it's only assigning itself an internal IP address. It's behaving as if there's no ethernet cable going into the machine at all.

Very very frustrating. That's what I get for updating immediately...

Is the LAN light in the cable modem on, indicating a connection between it and the mac? Do you know if the cable modem has a built-in router? If so, set your IP manually and set the cable modem IP as your router. Other than that..repair permissions..can't really think of anything else.

Yes, and when I have the machine connected to a router, it can see the other macs on the router and it can connect to them. But it can't access the internet.

Sounds similar to the 10/100 networking bug introduced by OSX earlier. Maybe 10.3.2 is killing networking again?

I'd have to (and all of you too) seriously question Apple's QA team if this is the case.

You don't already?

This looks like either a dns problem, or a gateway problem.

Is the info shown in the network preference pane correct ?

Can you access the web by ip addresses ?
appleinsider (and macnn) is at 216.22.45.53

Before deciding that Apple has spontaneously disabled your networking, how about posting some real troubleshooting info? Like the output of ifconfig -a, netstat -rn, the contents of /etc/resolv.conf, a sample ping by name and a sample ping by address?

The resolv.conf file is empty and pings to both yahoo.com and its IP fail completely. The physical connections are all fine because I can access any of the other computers behind my router.

What kind of router are you using?

[Y3a]

Shut down your machine, and Zap the PRAM. This resets ethernet and other ports.

I am using an AGP 400, not a B&W G3. I thik I remember that you have to turn on networking from several different screens.

I am using a Linksys Wireless-B Broadband router, model BEFW11S4.

Tried this, still doesn't work. I also did an archive and install of 10.3, and I STILL had the same problem. I just upgraded to 10.3.1, and that doesn't fix it either.

Then it is extremely unlikely that it had anything to do with 10.3.2 other than coincidence. I just installed 10.3.2 on my laptop with no change in networking whatsoever.

What you are getting is a link-local IP address which is the result of either no DHCP server responding or you aren't physically on the network. I would first check that you get a link on both sides (the router should have a light, and the Mac should say. In OS 9 it used to show up in TCP/IP - I am not sure where it is now. If the link is there on both sides, try a static IP - just make sure you get it set up correctly.

Didn't I just see a firmware update for that model in the last few days? I'm pretty sure I did.

Edited: I just checked Linksys, and I was mistaken. Last firmware update was in October.

One of their wireless models just got a firmware update, but I can't find the article.

Have you tried contacting Linksys? They are pretty good about customer support.

I am certain that there is a link on the router, the light is on and I can connect to other machines on the network. I tried to connect the computer directly to the cable modem, and that was no-go. I also tried a static IP, and that also failed to work. The only solution I can think of is to have one computer share internet access over ethernet, but that's highly unelegant. I'm going to try and do a clean install on my machine, and if that doesn't work, I have zero things left to try.

How can you connect to other local machines? Using FTP, AFP, Web, etc? Can you do this when you have the link-local address (169.254.207.48)?

Does your router use NAT? Maybe we can get this worked out with the following info:

1 - What is your routers internal IP address?
2 - Can you give us at least one other configuration that works? (IP, subnet mask, gateway address, DNS address)
3 - What did you try when you set this up statically? (numbers)
4 - What numbers did this system have before (Same as for question 2)
5 - What interfaces does this mac use? (Ethernet, Airport, etc).
6 - What communications do work? (be specific, preferrably use communication with the machine from (2) as an example)

It is interesting that you don't have any traffic bound for a gateway other than local. I am not sure what link#4 is, but my system has link#4 AND my gateway as destinations, so that is probably your problem if you can communicate with others on the subnet but can't get out.

no problem here so far.

Using Airport on my iBook as a software base station to the MDD (Ethernet).

[mintcake]

I'm using the exact same router as Seamus, a Linksys Wireless-B Broadband router, model BEFW11S4. Before I install 10.3.2 on my 12" RevB AlBook, can anyone with the same router confirm that they *have* managed to install it without problems?

[Back up 15 and punt]

I had a similar problem. After installing 10.3.2 I ran into a number of problems. I had three kernel panics after trying to wake from sleep and my internet was inconsistent. I could receive mail but I couldn't access certain web pages and not all pages downloaded completely (ie Apples web page, most of the new web pages). I also couldn't download any other Apple updates except from my .Mac account where I downloaded iTunes 4.2. I was planning last night to call Apple this morning but I got a little surprise about 7 PM last night. Everything suddenly started working.

[wadesworld]

Crap like what? How is someone supposed to troubleshoot a problem for the guy when all we got was "Apple hosed my network connection!"

We have no what the problem is, or what caused it. Yet the assumption is, Apple released an OS update that is buggy and completely hosed the guy's computer. I think that assumption presumes too much without evidence.

[wadesworld]

While I don't appreciate your tone at all

My tone is that you're blaming Apple for something which may in fact, not be their fault. I'm asking you to gather evidence first. If that's "mean" well....

I tried to connect the computer directly to the cable modem, and that was no-go. I also tried a static IP, and that also failed to work.

How is your network setup? Does the router get a DHCP address from the cable modem? Does the router then hand out DHCP address to the machines on your network? Does the router do NAT? How is the NAT setup?

How did you connect to the other machines on your network? Are they OS 9 machines? I won't be surprised if you're connecting to those machines over AppleTalk, which doesn't require IP.

As for connecting directly to your cable modem, you probably have the wrong type of cable. You would likely need a crossover cable to do so.

As for assigning a static IP, what IP did you try to assign? What gateway address did you try to assign? You can't just run around assigning static IP's on a dynamically addressed network unless you're sure of what you're doing.

net 169.254.207.48 netmask 0xffff0000 broadcast 169.254.255.255

As was pointed out, this is an auto-assigned address, that gets assigned when DHCP fails. Is the router responding to DHCP requests? Have you checked the log on the router or turned on debugging output?

It's quite possible that what has happened is that your router is refusing to hand out an address for some reason. This wasn't a problem when your machine was booted before - it had acquired an address a while ago when the router was working and when you rebooted for the 10.3.2 install, the machine tried to acquire a new address and failed.

I have no problems.
