Win7 doesn't realize TCP/IP is already on DHCP ???

12/09/2010 04:00:29 PM · #1

ETA: I think I've found the solution. See post #18, below:

Every time I reboot on the wired network at work, I lose my internet. Network drives can be mapped and everything on the network can be pinged, but I cannot get out onto the internet.

Looking at IPCONFIG, there was an extra gateway "0.0.0.0" in addition to the actual gateway listed. I changed the PC from DHCP to static, then Win7 found a problem and fixed it. Voila, I have internet, and the PC is magically back on to DHCP which somehow works, while it didn't before.

Is there a fix? Windows 7 is seeming kinda suckish to me so far.

I have only connected to my home, wireless network once, no reboots, so didn't find a problem there... yet.
Here's a video showing the problem.

Oops, when I say "network" in the video, I actually mean "internet". :-/

I had that problem regularly on Vista, including after waking from sleep. I ended up writing a batch file to delete the 0.0.0.0 gateway on login, because Windows kept trying to use it as the default gateway. After I upgraded to Win 7, the problem disappeared, and I assumed it was Vista-only. Sorry to hear it's not. I have since moved to OSX at home. Changing NAPs worked for similar funky wireless network issues.

Hmm... I just unplugged it & packed it up. But then I had an idea to turn off IPv6 and only let IPv4 run, so I unpacked it, pugged in the network cable, but not the power. Turned it on and it worked.

There were some Windows updates that ran on my last shutdown... my only explanation. We'll see what happens on my wireless at home tonight, and wired at work again tomorrow.

Hmmm... I can honestly say that I have had no such issues with five different machines running either Vista or Win7 on my home network (either wired or wireless), and have not had the issue with two laptops running Win7 on any network I have connected them to.

It got onto my home network with no fanfare just now. Maybe it's decided that it's just not worth messing with Slippy. >:-)

when you ipconfig it will show all adapters, so if you were running wired, the 0.0.0.0 was probably your wireless card. If you could access network resources but not teh internet at work it was probably your company's isp

i had a bitch of a time with windows 7 and my notebook, turned out it was my wireless router. static IPs are the key.

i cannot not for the life of me get win7 to network with all my pcs in the house. this was so, so easy in xp.

i dont know what happened or why they felt they need to make it "easier" which only complicated matters.

they like to make things "easy" for the average mom and pop, which usually means its going to frustrate IT people. For instance, I actually like Win7 quite a bit but it drives me crazy that I cannot simply right click the icon in the tray to get ip info anymore

I did have the wireless adapters turned on at one point, but turned them off at work to make troubleshooting the wired easier. I'm pretty sure it had to do with the extra gateway listed in the IPCONFIG. I though maybe it was from IPv6, but didn't get a chance to test it. I should've videotaped the IPCONFIG to show what it looked like.

maybe a dumb question but is you router set to be a DHCP server.

Yes, but it may be set to limit the number of connections, I'll check tomorrow, good point.

Though the DHCP does work after I do my 'fix'. But I fully expect it to just work straight away tomorrow. I think the bug has somehow worked itself out... very mysterious!

ive always found static IPs to be the savior, there is always one device on my network that is determined to use an already taken IP.

i have one device that cant do dhcp so i set the ip to 192.168.1.100. and don't you know out of 998 other ips available one of my pcs was determined to use that one on occasion. go figure.

made them all static, no more problems, now if i could just share files...

You should be able to share. Browsing for the shares doesn't always work, but as long as you set up a shared folder on one PC, you should be able to map to it manually using the IP number of the PC... "\\192.168.0.xxx\share"

IP addresses don't work that way. You only have 254 addresses per octet. ie: 192.168.1.1-255

The problem was probably caused by Adobe CS3.

Here's a link.

Here's another link that lead me to the previous one.

So I can either do that fix, or, apparently, installing iTunes will update the Apple Bonjour Service so it will stop adding the extra gateway in my ipconfig.

I was thinking about iTunes, as I have a lot of drive space, and it would be nice to separate my list from my wife's and all the crap she has.
