Windows 7: Cant set network location to private/no internet access

20 Oct 2009   #1

Cant set network location to private/no internet access


I have a test machine that had a wired gb nic installed. I've removed that and installed a D-LINK DWA-547 rangebooster. I want to move the PC to my 2nd lounge room which is uncabled and connect it to my plasma TV.

Note that I have a PS3 running in that lounge room. Despite having a line of sight from PS3 to wireless router over a distance of 17 feet only, the signal strength wanders between 35 - 50%.

Please forgive the length of this post, it is a reasonably extensive set up I have here.

Anyway, back to the problem;

I have a netgear WNR3500 gigabit wireless router. It connects to a motorola cable modem. Port 4 of the router connects to a DLINK 16 port gigabit switch, and there to 7 PCs, a network printer and an IP camera.

One port of the dlink then connects to a D-LINK 8 port DGS-1008 gigabit switch in the primary lounge room which then connects to a PC connected to the first plasma TV, and to a BeyonWiz PVR.

Each of the machines, printer and IP camera uses a static IP address, With the exception of one PC running Windows XP SP3, all PCs are running Vista Ultimate SP2. Each machine reports a Gigabit connection.

The Windows 7 PC is running RC 7100. I have disabled searching/indexing, homegroups and offline files support.

As all data is stored on the XP machine with 4.5TB of storage, and everyone in the family has mapped drives to the server and understands the structure I have no need of the above services. Although, disabling indexing and offline files causes problems with shell folders on network locations.

Once I added the wireless NIC the connection configured itself automatically as an "unidentifed network" as a public network.

For the life of me I cannot set it to private. I want it to be a home network. As a public network it blocks internet access.

I've tried everything from deleting the wireless network, to running the diagnostic tools, to reinstalling drivers, manually setting up the network, checking I have the latest firmware for the router and so on. Nothing works.

When I go to "choose a homegroup" I can select "Home" as a location, (and this is the only place in which I can do that), which then takes several minutes to attempt to configure the network, and ultimately fails.

A second problem encountered whilst trying to resolve the first problem, When I run the diagnostic and troubleshooting tools I note that the ping time to a random website (, jumps from 20ms to 400ms (as seen from another PC on the network), and stays there until I reboot the router. My son reports that ping times in counter strike jump up to 800ms. Cancelling the troubleshooter's doesn't fix it I have to reboot the router. At one point, it killed the network connectivity for everyone completely until I rebooted the router.

So, what I'm trying to achieve is to get wireless internet and intranet access working on a Win 7 PC so I can map drives to my server, and connect to the internet, using a 50" plasma as a monitor.

Again, sorry for the length of the post.

Can anyone help?
