I have a WNDR3400 router that works great on wireless, also works great
when another PC is plugged into LAN port 2 BUT will not hold an internet
network connection on my main PC using LAN 1 with Win7-64. It tries to acquire
& does so briefly but disconnects after 4 or 5 secs. Network 2 using
just the modem connects OK. Network 3 with the router installed will
not hold an internet connection after 5 secs. Troubleshooting tells me
there is an ethernet cable disconnected but it works with modem only.
I have tried many different cables but results are always the same.
It does not seem to be a hardware problem. Probably a corrupted file
somewhere in windows. In my "Network & Sharing Center" screen, to the left shaded area I see
Control Panel Home at the top, followed by "Change adapter settings" &
below that, "Change advanced sharing settings". At the left bottom, I
see HomeGroup, Internet Options & Windows Firewall. In the middle
white part of the screen, I see W7-PC (my computer) with a line going
over to the internet with a big red X in the center. To the right of that,
I see this "See full map" Below that should be the Network if it was
working. To the right of that is "Local Area Connection 2".
At the bottom is the topic saying "Change your network settings"
and it list 4 of them. If I try to troubleshoot or create new networks,
it ALWAYS says I have a ethernet network cable unplugged and to plug
it in or change the one I have which I have done with about 6 different
cables. Network 2 (modem only) works good but Network 3 with router
tries but can't maintain the internet connect???

I had the same problem with a WNDR3700 and it drove me crazy. It started with me after a firmware update. Tried EVERYTHING....firmware rollback, W7 rollback, factory reset etc etc. I only got the router to work normally again by flashing DD-WRT (HTG has a great "how-to"). Hope this helps.

I'm not sure what you are trying to tell me with the above post.
flashing DD-WRT ? (HTG has a great "how-to")?
I think that the problem lies somewhere in the Local Area Connection
with network address connections. This is where I think the fault is:

Local Area Connection 2 Properties:
Connect using: Realtek PCIe GBE Family Controller.

1. Client for Microsoft Networks
2. PANDA NDIS IM Filter v.1.6.0.42
3. QoS Packet Scheduler
4. File & Printer Sharing for Microsoft Networks
5. Realtek Teaming Protocol Driver (NDIS 6.0)
6. Realtek Vlan Protocol Driver (NDIS 6.0)
7. Realtek NDIS Protocol Driver
8. Pure Networks Device Discovery Driver
9. Pure Networks Wireless Driver
10. Internet Protocol Version 6 (TCP/IPv6)
11. Internet Protocol Version 4 (TCP/IPv4)
12. Link-Layer Topology Discovery Mapper I/O Driver
13. Link-Layer Topology Discovery Responder

All the above 13 connections are check-marked

In the Network Connections screen, it has the Local Area Connection 2
but next to the big red X it says, "Network cable Unplugged"

Make sure the cable is plugged in properly, and if that doesn't work, try a new/different cable.

I have 6 different cables & have tried them all.
They all work with Network 2 (modem only)
but just acquire briefly with Network 3 (router installed)
On Network 3, the signal is acquired & I get the internet
briefly but disconnects after about a few seconds. The
connection tries but can't stay connected on Network 3.

Have you tried RESETTING the router to the initial state?

Network 2 and 3 are just settings... the fact Network 2 works to the Modem probably means the network card's connector is OK. Network 3 goes to the Router and fails. Your still using the same cable connector though.

That doesn't mean you network card is OK though. For instance it might work OK at 100Mbps but not 1Gbps?

What are the various speeds of the cards you have? The modem lan connection speed? The router Lan connection speed, and the other computer that connected to Router connector 2?

If there is a mix of 100Mbps and 1Gbps connections and your problem is with 1Gbps, there could be a bad cable, works fine at lower speed. You can also via the Network Card settings make it run at 100Mbps as a test.

This problem has been going on for about 2 weeks so powering up, down or sideways
has already been tired numerous times. Both Net 2 & Net 3 work !!! B-U-T,
only Net 2 (modem only) will keep the internet connection. Net 3 (with router)
acquires & keeps connection for about 3-5 seconds before terminating the internet.
I have tried a 7 cables I have in all positions & the result is always the same.
Fact of the matter is: Both Networks see the ethernet cable connection but only
1 of them keeps it. Net 3 tries to acquire about every 35-45 secs with router in
but never keeps the internet longer than 5 secs. I think the problem is windows
software. Netgear thinks it is too but Microsoft in their infinite profit scheme
won't help without some $$$ being thrown their way. I think the problem is here:

Local Area Connection 2 Properties:
Connect using: Realtek PCIe GBE Family Controller.

1. Client for Microsoft Networks
2. PANDA NDIS IM Filter v.1.6.0.42
3. QoS Packet Scheduler
4. File & Printer Sharing for Microsoft Networks
5. Realtek Teaming Protocol Driver (NDIS 6.0)
6. Realtek Vlan Protocol Driver (NDIS 6.0)
7. Realtek NDIS Protocol Driver
8. Pure Networks Device Discovery Driver
9. Pure Networks Wireless Driver
10. Internet Protocol Version 6 (TCP/IPv6)
11. Internet Protocol Version 4 (TCP/IPv4)
12. Link-Layer Topology Discovery Mapper I/O Driver
13. Link-Layer Topology Discovery Responder

All the above 13 connections are check-marked
In the Network Connections screen, it has the Local Area Connection 2
but next to the big red X it says, "Network cable Unplugged"

The cable is NOT physical unplugged, win7-64 just thinks it is !!!

I have updated the "Realtek PCIe FC driver already.
What do you refer to when you say NIC drivers?

I updated AFTER the problem occured. I just tried to download & install some
Intel NIC drivers but in the middle of the install, it informed me that i had
no Intel Adapter installed & could not proceed. I wish NSM would put out
a product that they would stand behind, not just junk to make $$$....

welcome FAdmiral ,
my suggestions
1. turn of router/routers
2. unplug the cables
3. wait for 2>3 min ,
4. turn on router , plug the cables in

ACCORDING TO ME :
THE PROBLEM LIES HERE
:1) OPEN ITNERNET EXPLORER
2) CLICK ON TOOLS>INTERNET OPTIONS> CONNECTIONS tab
3) SELECT THE NETWORK CONNECTION U WANT AND OPEN ITS SETTINGS
4) THEN U SHOULD PROBABLY FIND "Use Auto Disconnect" , and u know what to do ...

Welcome mysticgeek123,
Unfortunately just turning off everything for long periods of time has
already been tried by me many times to no avail. In internet Properties,
Connections tab, I have only the setup button for dial-up first, below that
is the big white box for dial-up & Virtual Private network settings (box is empty)
with add & add VPN buttons on the side. Below that is a grey out "Never Dial a
Connection" checked. Below that is the Local Area Network (LAN) settings.
When I click that button, I get 3 choices:
1. Automatic detect settings (checked)
2. Use automatic configuration script (unchecked)
with blank address box below greyed out.
3. Use proxy server for you LAN (unchecked)
and all boxes below greyed out

I believe that somewhere in the "Local Area Network 2"
that displays is a corrupt file that reads "Network 2" (modem only)
just fine but thinks that "Network 3" (router installed) has the cable
unplugged. It tries to connect & does so briefly but can't maintain
the connect for more than a few seconds. Every indication points to
software rather than hardware but just where the problem is ???
This is what I am trying to find out.....

OK, could not solve the problem with direct wiring to the ethernet port on the PC
SO I purchased a Netgear WNDA3100 wireless connector & got into the internet that
way from my PC. So this problem is solved somewhat now I have internet access....
