Right, this is doing my nut.

I don't have any issues connecting via wifi, however whenever I try to
connect to my router via ethernet, I have a host of problems.
Whether trying to use DHCP or assign IPs staticaly, I get the following -

Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::ed42:547:5d1b:20ef%9
Autoconfiguration IPv4 Address. . : 169.254.32.239
Subnet Mask . . . . . . . . . . . : 255.255.0.0
Default Gateway . . . . . . . . . :

If I've set it manualy, often, when I go back to IPv4 properties, the
gateway detals have been erased. If I then try to add them again, windows
warns me about adding a second default gateway. If I proceed & ignore the
error, Vista does indeed add two defalt gateways. Either both being the
correct IP or one being correct the other being random.
The correct IP should be 77.75.xxx.xxx with a 255.255.255.248 subnet. The
above IP & subnet are completely random.
(I'd like to note now, that I didn't used to get this issue, so I presume it
may have something to do with the Vista updates)

I've tried disabling IPv6 (as someone mentioned earlier) & it has made no
difference. This occurance is not subject to my router alone. Working in IT,
I'm frequently going between different networks & different equipment, this
is making my job impossible.

Cheers,
Doug
 
Since you are using 77.75.xxx.xxx, I assume you use ISP modem without router. In this case, these are some of options:

1. Disable IPv6.
2. Upgrade NIC driver.
3. Upgrade the modem firmware if it is possible.
4. Disable the DHCP BROADCAST flag in Windows Vista
5. Install Microsoft update for the Vista.

I actually have my own IP stack routed to me. I'm using a Vigor Draytek
router with latest wares, so that shouldn't be the problem. Likewise with my
Intel NIC.
Will try the reg tweak when I have a second.
I've got all of the updates Vista has requested. Are there more?

I'll have a look at the rest & report my results.

Right, I haven't yet made any changes, however earlier tonight I had the
issue again & this time with both my wireless & my ethernet.
I went into the registry & manually deleted these random IPs & subnets & it
seems to have done the trick.
What could be the cause of these IPs getting set?

I exported the registry before I made the changes. I presume I could chop
out the appropriate bits if anyone is interested in having a peek?

Anyone else had/heard this problem?

Doug

You're seeing the default IP when the NIC can't get the DHCP connected. If
you wait, it may be fine. Otherwise in the TCPIP properties-advanced, put in
your router's IP as the gateway.
 
?
As I said, static IPs don't (or didn't) work - which includes the rollback
IPs.
After a little research, it appears windows does assign random 169.254.x.x
addresses when it has DHCP problems.
It can then occasionally be rather hard to get rid of them.
I view this as a bug in Windows. If it can't find a broadcast IP, then the
loopback should suffice. It then highlights another issue with the default
gateways.

The microsoft page shows you how to get around this bug, but not fix it.
If people still get issues, the following may be of interest:
