Windows 7 Home - Network connects EVERYWHERE but my work - but then again - sometimes it does!
New lap top just 2 months ago. Windows 7 Home. Connects to my new Linksys N Router. Connects to my old office hard wire to the router. Connects to McDonalds hotspot, etc,. etc.I get to my new place of work - they have a wireless g. I got it connected. I can see all devices - I can even print to the printer. Internet will not connect. I notice that the active network connection keeps getting a different name:GRSCH1 1GRSCH1 2GRSCH1 3etc., etc.If I plug in the hard wire - same thing. I can see all devices on the network - but ZERO internet connection.Then one day - the computer was just sitting there both plugged in and wireless both turned on and connected - and I noticed my Exchange server connected. I HAD INTERNET. Lasted for about 1 minute then shut off again. This happened intermittently through the night. I also notice if I reset the company router - the computer has internet for about 1 minute - then goes away again.Another night - just a couple days ago - it seemed to have connected and was holding the connection for awhile. SUPER fast connection here hard wired - by the way. Anyway- I unplugged and replugged to see what would happen - nothing. COnnects to the network - I can see devices - BUT NO INTERNET!!!!!This is very strange and 4 IT people here - including the head goat cheese - say it's my computer. They don't have any fancy firewalls, etc. There are at lest 20-40 people that bring in their own laptops and plug into the live wire or connect wireles - all have no problems. They were always plug and play.So perhaps there is something going on with my computer - why is it naming the same network connection with different numbers?HELP!Thanks!

You posted bunch, but nothing to use to trouble shoot.Make / model / firmwarelaptop / router / wireless cardrouters / switches need to support windows 7http://www.microsoft.com/windows/compatibility/windows-7/en-us/default.aspx

David, Sounds like the "head goat cheese" is right (BTW I think you gave plenty of info to get started, but the other data would be helpful too). Your PC is the only variable that is consistent between the problem and the "control" group. It is really interesting that it connects everywhere but work, and you can see the work network. What are you using to test connection to the internet? I am going to go out on a limb and assume that you are either using a Browser (Not that reliable) to go out to internet sites, or you are using the network connection status (much more reliable, but not 100%) to see this. I realize you are probably saying "what's the difference?", but the difference is "can you not connect?", or "can you not connect to some services?" (or using some applications). Lets take as much out of the picture as we can, and simplify things as far as we can. I am going to ask you to try a couple of things while connected via hardwire to your company network. Please post the output here (where applicable), so we can see what is going on. These should at least get us any low hanging fruit. -Make sure your network drivers are up to date -From a command-prompt run the following (record and share output): ipconfig /all nslookup microsoft.com telnet <IP> 80 -Use the result from the nslookup for the IP in the telnet command. If you do not get a result use 207.46.232.182 and/or 207.46.197.32 NOTE: you may have to install the telnet client on Win7 here are some instructions how to install and use the client: http://cbfive.com/blog/post/Using-and-Installing-the-Telnet-Client.aspx -If the above fail (or you are not sure if they failed) boot the computer into safe mode w/ networking (by pressing F8 during boot) and test both of these again, as well as just trying to browse to any public website. Let us know how things go. If you need extra help, you can reach us at: InitialAssist@cbfive.com See my blogs at http://www.cbfive.com/blog - Jared Crandall

I have a new HP ProBook 4510s (Windows 7 32-bit) that is experiencing this same problem. It worked perfect for two weeks. Then yesterday morning, coincidentally after I updated the firmware of our router (Linksys RV082), this one computer could not reach out to the internet via the wired connection. Symptoms: -Can connect to any shared file on the network and print to network printers -Can ping the gateway, but cannot load the http interface of the gateway -Cannot ping any outside ip address (I use Verizon's 4.1.1.1 because it always replies back) -Wireless adapter can reach out to the internet, only wired connection is affected. Troubleshooting steps: -Connected to other ports on the router -Uninstalled network interface and reinstalled -attempted update of driver version of interface, but already have the latest version -Reset Router to factory defaults, restoring previous firmware version -Attempted tests in Safe Mode with Networking, same problem -No proxy server redirection set in Internet Options -Hosts file (and others neighboring it) is set at default values -Nothing unusual found in Windows Firewall (I'm not that familiar with Win 7 Firewall, there may be some new menus I don't know about) -HP support found nothing wrong with the computer -Cisco (Linksys) support found nothing wrong with router configuration Final Thoughts: I would hate to think my last resort would be to re-install Windows and start from scratch. But at this point that would have been the quicker solution. The biggest problem is that wireless doesn't exist where this computer normally resides.

I forgot to mention that I also did a system restore to two days prior when the internet connection still worked.

Okay, before anybody answers... I have a second computer with the same symptoms. It is also a newer HP Notebook computer and the only other computer in the company with Windows 7. I haven't looked at the details of each network card to see if the dirver matches but both network cards are Marvell Yukon.

The Linksys RV082 is not compatible with windows 7, you can try to disable IP binding on the NIC. I have the RV082 as well I use static IP's and have no issues, if I use DHCP of the IP's I have flaky Inet access
