OK. I'm gonna jump on the bandwagon and ask for help with my connection issues.

I've got an HP laptop with Vista Business on it. I've been connecting to the internet through a wireless network (Netgear router) for about a month with no issues. But suddenly, out of the blue, no more connection:
- "Local only" access to an unidentified public network (Huh?)
- "Limited connectivity" to an unidentified public network...

No external interference. I have 2 computer next to each other: one connecting, other not...

What I've done so far (to a point where I'm ready to throw my computer out the window... ):

- Release and renew ipconfig : "Unable to connect your DHCP server"
- Specifying a static IP address (for Internet Protocol v.6 and v.4)
- Uninstalled and reinstalled my WLAN adapter (Broadcom 802.11a/b/g WLAN)
- Pinging : transmit failed, error code 1231.
- Uninstalling my Norton anti-virus software
- Restart my computer MULTIPLE times.
- Disabled my firewall

Nada.

This is what I get when I run "ipconfig /all" in my DOS command prompt:

I am at wit's end. Please help! Does anyone have a definite answer for this issue?

Thanks!

Definite answer? Probably not. We can suggest some steps that may work to solve the issue.

TCP/IP stack repair options for use with Windows Vista.

Start, Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

In the command prompt window that opens, type type the following commands:

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.

Thanks for the suggestions. Tried them, and outcome: It didn't work.
Still have only "limited connectivity".

Got more suggestions?

I've even considered going for the "File > Restore Defaults" option in the the Computer Setup (F10 during startup), but I don't know what might happen...

I don't mind resetting settings. As long as my content stays intact, I'm up for anything.

Thanks!

[JohnWill]

Did you try a system restore?

[AntiDot]

Like from a backup? I'm really bad with backups... The latest backup I have is of when I first got my computer, i.e. factory settings.

Like I said, if I can be sure that all my content will be save and waiting for me when I'm done, I'll do almost anything. But I'm not tech-savvy enough to trust myself with these kind of decisions...

[JohnWill]

No, a system restore, not a complete copy. You do know about System Restore in XP and Vista, right?

Take a look at this: http://www.bleepingcomputer.com/tuto...torial143.html

[AntiDot]

Have never done any hardcore computer maintenance, so no, not really... (I know, I know. A lesson well-learned...)

But I know about it now, and I've restored my system to a point where I know everything was working still working. And guess what?!

My internet seems to be working again, and my personal docs are OK!

Thank you for your patience. I really appreciate it.
Enjoy the weekend!

I was having the same exact problem with my new custom built desktop except it has dual-ethernet. I uninstalled Comodo Firewall and everything went back to normal.

Glad we could help.
