I have a problem with setting up an ethernet cable through a Netgear XAV2001 adapter that runs from my modem through the mains power lines. I have access to my email and just downloaded windows updates, but cannot access the web with IE or Chrome.
I have reset the modem several times, did a ipconfig/renew; turned off the wireless connection on the desktop.

The ipconfig settings look like this......

Any suggestions?

I would suspect DNS settings. Check if it is resolving addresses correctly or try connecting with some servers by IP.

I am not sure if I am checking the resolving addresses issure, but I can put either URL or IP addresses in the browser heading and still get "unable to to access the network"

In trying to check on this resolving issue I discovered that in my Contorl Panel Network Connections, the Advanced tab for my ethernet connection status, which has a list of Property that are enabled or not enabled, shows Value NOT Present for Network Address. Should there be a network address for that property?

No, this field usually has the value "not present".

Go to your realtek NIC properties. Select IPv4 and hit properties. Leave the obtain IP automatically selected, but change DNS to manual. Fill it with appropriate addresses from:

See if that helps.
If not see if you can connect with your modem. In your web browser address bar enter 10.0.0.138.
If it is not successful ping this address from command prompt.

Well no happiness there ... I can not access the modem with the 10.0.0.138 in the browser address bar, but when I ping it in a command line, I get:

Pinging 10.0.0.138 with 32 bytes of data:
Reply from 10.0.0.138: bytes=32 time=3ms TTL=64
Reply from 10.0.0.138: bytes=32 time=4ms TTL=64
Reply from 10.0.0.138: bytes=32 time=4ms TTL=64
Reply from 10.0.0.138: bytes=32 time=3ms TTL=64

Ping statistics for 10.0.0.138:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 3ms, Maximum = 4ms, Average = 3ms



I gather that is just mysterious--the ping seems to work OK, but the browser address line does not. What next?

I really appreciate your time on this....Thanks

I'm at a loss here. Your ipconfig seems to be ok, there is connectivity with your modem, so network is working. There has to be a problem with some software setting. Some wild guesses:

0. Set DNS back to auto if you haven't already.

1. Disable your wireless network card in device manger. Reboot. Test.
2. Disable IPv6 (Untick it in realtek card properties). Reboot. Test.
I don't like those tunnel adapters for ipv4<->v6. If they don't disappear after unticking ipv6 do the following from command prompt:
netsh interface ipv6 isatap set state disabled
and
netsh interface teredo set state disabled

3. Make sure that your web browsers network settings are ok (no wierd proxies etc)
4. Ping or traceroute google.com from command line.
