Here is a list of Network Connection Fixes I have read about.
(Ignore the html coed)
<P>1. Click "Start" and type "Fix Net" and press enter to let windows try to diagnose and repair problems.
<P>2. Verify network drivers are up to date for your adapter... (upgrading may
use old Vista drivers that are not compatible with 7) Click Start and type
"Device Manager" and look for any driver errors.. usually a yellow triangle.
<P>3. Click Start and type and enter "ev" and it will run the Event Viewer. Look
under Custom at the Administrative logs. Problems with initializing drivers are
logged here at startup.
<P>4.Click Start and type "perfmon /report" and press enter... it takes 60 seconds
to gather a comprehensive diagnostic report and then it presents resolutions.
<P>5. Disable NORTON and all AV programs and Firewalls. Norton 360 is NOT
compatible with Win 7.
<P>6. Reset the router and test
<P>7. Bypass the router, connect directly to modem and test - not exactly a fix but narrows the problem.
<P>8. Go into your device manager. (Control Panel --> Device Manager) and open up the
drop down list under Network Adapters. Find your network controller(s), right
click it (them) and uninstall. After uninstall is complete, click any other
device in your Network Adapters and choose "Scan for Hardware Changes". Windows
should automatically detect and reinstall your network controllers.
<P>9. Go to Task Manager /services /services
and Disabled the "Function Discovery Resource Publication" service
Note: Windows 7's new "HomeGroup" connectivity requires this service.
<P>10. Remove the Bonjour service if you have Apple/iTunes
- Click Start and enter and run this command: "C:\Program Files\Bonjour\mDNSResponder.exe" -remove
- Navigate to the following folder in Windows Explorer. "C:\Program Files\Bonjour"
and Rename the mdnsNSP.dll file in that folder to mdnsNSP.old
- Restart your computer and DElETE the "Program Files\Bonjour" folder
<P>11. Fix for NVIDIA USB Enhanced Host Controller Interface (EHCI) chipset BUG

<P>12. Cannot get IP address
http://support.microsoft.com/default.aspx/kb/928233
<P>13. Unidentified Network
Go to the NIC properties and uncheck these things:
-Internet Protocol Version 6 (TCP/IPv6)
-Link Layer Topology Discovery Mapper I/O Driver
-Link Layer Topology Discovery Responder
<P>14.Make sure that all wires are connected (for example, make sure your modem is
connected to a working phone jack or cable connection, either directly or
through a router).
<P>15.If you're trying to connect to another computer, make sure that computer is on
and that you have enabled file and printer sharing on your network. For more
information, see Networking home computers running different versions of
Windows.
<P>16.If your computer has a wireless network adapter, Windows will automatically
detect wireless networks that are nearby. To see a list of wireless networks
that Windows has detected, click the Start button , and type "Conn" then click
Connect to netwok. If Windows does not detect a network that you think is in
range of your computer, open Help and Support and search for "Troubleshoot
problems finding wireless networks."
<P>17. Still not working? Did you do a clean/custom install?
Upgrading frequently fails for too many reasons to list.
<P>18. If these steps don't solve the problem, look for a specific problem in the following list.
