Is there any way to make DHCP log back in automatically?

My computer is on DSL behind a router that uses DHCP. The connection was dropped this morning and Mac OS X's DHCP did not log back and in and get the new information from the router. I had to change the Network preferences to BootP, close the panel, and then return and select DHCP again. OS X logged back in to the router.

that's odd
my cable modem uses DHCP, and i've been playing with a local network to put my new laser printer on - yesterday i cut the connection several times from the cable modem to the mac, and every time, OS X re-established the connection within seconds. i even checked the IP's, and they were different each time...

I have a similar problem - I work in an enterprise that has DHCP servers all over the campus. When I go from one physical location to another, I'd like to put my PB/G4 running OSX to sleep, and wake it up in the new location and gain a new DHCP lease.

I fixed my DHCP problem, but boy do I feel foolish.

Did you find the BSD networking command to force DHCP to drop/renew an IP lease??

Hmm. Sounds, for one thing, like the first poster wasn't noting a problem so much as how smoothly DHCP works for him. DHCP is *supposed* to give you a new address if you cut your cable modem connection, especially since there are so many people on that same system starting up/restarting/etc. their own computers. There would be quite a bit of IP shuffling.

I'm getting similar problems with 169.x.x.x
I've got a DSL line running through an ethernet switch.
When I first hooked up my new powerbook it got a good address, but after disconnecting it then reconnecting it later, it hasn't yet been able to get a good address. When I only had os9 on my B&W G3 it had the same problem - I tried trashing the TCP/IP prefs, to no avail! Now that I've upgraded the B&W, it got a bad address the first time I tried connecting. I switched to PPP in the Network panel, hit "Apply Now", switched back to DHCP, hit "Apply Now", and it momentarily showed 0.0.X.X, then got a good address. Interestingly, when I get a bad (169.x.x.x) address, the subnet mask is set to 255.255.0.0 and I don't get a router address.
Could this be a problem with the DHCP server? Is there a file to edit or trash in OS X that has DHCP settings or info? Does Apple's use of DHCP with AirPort have anything to do with this?

I personally would like to know what the answer is... I don't shut my system down and would perfer to put it to sleep but getting a 169.x.x.x address instead of the proper router DNS address is a pain.

Check to see if you have set your router with enough IP addresses to hand out. Something that says starting IP address range to ending IP address.

Sounds like another case of an open transport issue. Funny thing if this was a "standard" wireless device (res. gateway) it wouldn't try pushing a 169.x.x.x ip first and wouldn't cause things to screw up. Just like OS10.x open transport problems. |
