Specs: Windows 7
I’m having a real nightmare with my Windows 7 Install. Pleeeeeeeez help.
Andy.

 Running a Sony Vaio VGN-A317M
 Have a DLINK DSL-G624T. On the DLINK web-site this model is NOT one of those listed as Windows 7 compatible. I can’t seem to determine if this is the problem right here.
 Have also got a Samsung XP laptop, running and connecting perfectly.
 Complete new install of Windows 7 Home Premium (from XP) on the Sony
 Windows 7 Upgrade Advisor said I would have to look at:
o Intel PRO Wireless 2200BG Network Connection
o TI PCI7420 Integrated Flashmedia Controller
o Norton Antivirus
o I installed anyway !
 Install seemed to go just fine
 I have not installed any other software. No Firewall. No Virus Protection. No Nothing ! Just standard Windows 7 Install software.
 With internet connection got:
o Local Area Connection" “doesn't have a valid IP configuration”
o Have also got Unidentified network / Public network settings and CANNOT get these to change
 I’ve tried various fixes from various forums but CANNOT get an internet connection
 I’m now plugged in via an Ethernet cable to my DLINK router (have tried with 3 different Ethernet cables)
 The router is working fine with my other (Samsung) laptop, using http://192.168.1.1
 CANNOT connect to http://192.168.1.1 using the Sony
o “IE cannot display the webpage”
 I “pretty sure !” I’ve updated the Realtek PCI GBE Family Controller driver properly, by downloading MANUALLY (via other laptop), but it *was* called something else before I updated the driver (can’t remember exactly what it was called before)
 Also, when I was trying to fix the problem I think I disabled the Wireless Connection (to simplify the network situation !), and now I can’t see it, or re-enable it any more. It’s not listed in Network adapters in Device Manager.
 Anyway, can’t connect to my DLINK router with the Sony, but I can with my XP Laptop using http://192.168.1.1 All seems normal there.
o DHCP Info is:
 Starting IP Address 192.168.1.2
 Ending IP Address 192.168.1.254
 Primary DNS 192.168.1.1
o LAN ( not WAN) info is:
 IP Address 192.168.1.1
 Subnet Mask 255.255.255.0
o WAN Info is:
 IP Address 79.156.190.238
 Subnet Mask 255.255.255.0
 Default Gateway 192.168.153.1
 DNS Server 80.58.61.250
 I’ve tried to set a static IP address as follows, but this did not work
o IP Address 192.168.1.22
o Subnet mask 255.255.255.0
o Default gateway 192.168.1.1
o DNS server 192.168.1.1
 After trying all of the above my config/all is as follows:
Microsoft Windows [Version 6.1.7600]

Ok so first open CMD (command line prompt) and try:
ping google.com

If this doesn't work, try:
ping 74.125.77.104

If this will work, you have a DNS problem.
So check the routers setup and figure out the DNS server, the router got from your ISP.

Then configure DNS server manually in your windows 7 and give it the ip address, you figured out in the routers setup.

The try again pinging the above addresses.

Hi Paulep, thanks for your reply.

On Properties / TCP/IPv4 I set the DNS server to 80.58.61.250, which is what i see on the DLINK router on my other laptop but still could not ping 74.125.77.104

I tried both "Obtain IP address automatically" and "Use following IP address" options in the TCP/IPv4 setting window.

Any other ideas ?

Thanks,
Andy

Oh just saw, that you have also Norton Antivirus installed. Is this including a firewall?
If so, you might have to deinstall and reinstall the Norton things.
Last time I often heard of problem with Norton Firewall, concerning network connections.
