I have a similar problem. I have a home office wireless/wired network. Router
connected to SuddenLink's cable modem.
I am writing from my laptop which has internet wirelessly & wired - I
checked both.
I have a Mac attached to the same network. I have internet there as well.
My new Vista 64bit machine that I got in July has worked fine and I haven't
had any networking issues with it. I plugged the cable in and it was ready to
go...
Now, as of 2 days ago, I have no internet, and am connected to a public,
"unidentified network" with limited and local access. I cannot connect to my
other computers anymore either.
Troubleshooting I have done:
* I have taken wired connections from the laptop/Mac, known to be working,
and plugged them in the Vista machine. Not the cable.
* I uninstalled the driver for the NIC card. When restarted, it detected the
adapter and reinstalled the drivers. Not the NIC card.
* I pinged 127.0.0.1 with success. I can ping the auto IPv4 address
169.254.247.64 with success. I get error code 1231 with 192.168.1.1 (router) .
* I had all the auto stuff selected for both IPv4 & IPv6, so I did the
opposite... I put in all the manual DNS/gateway entries (192.168.1.103 –
laptop was on 101 & 102, 255.255.255.0, and the 2 DNS entries it had listed).
When I ipconfig it still shows an auto configuration for IPv4 at
169.254.159.231 and a subnet mask of 255.255.0.0 and no gateway. I did a
release and a renew. Same thing. I check the device manager & it still has my
manual entries. Incidentally, I had made the change AGAIN to “private” vs.
“public” for my unidentified, local, limited network. Nothing. So I restart.
I'm back where I started: I’m “public” with the same autoconfiguration
numbers and in the device manager my IPv4 is again set on Obtain
Automatically versus the manual entries I had saved. Every time I reset the
network to "private", it resets itself back to public after a restart.
* I did a netsh int ip reset and a netsh winsock reset
* I have unplugged both the router and the modem and even reset the router
and reconfigured.
* I restored to the last system checkpoint before the issue occurred - which
incidentally was before some Windows update was installed (hmm...)
I'm lost - and I don't know who to call. It doesn't appear to be a hardware
problem (Dell or LinkSys) or an internet problem (SuddenLink), but it could
be a software problem (Microsoft) to which I have found NO SOLUTION to on the
Web.
