That article shows you what a normal IPV4 configuration should look like. IPV4
is the Internet Protocol that has been used since IP was developed, 20 or so
years ago.

With Windows XP, Microsoft added IPV6, which is more complex and offers much
more addressing possibilities. Using IPV6, unfortunately, requires a network
running IPV6, and other computers doing so. So computers running IPV6 have to
run several flavours of IPV6 - Teredo Tunneling is the most common - so they can
work over an IPV4 network.

So the computer that works - "Dads" - appears to be only setup for IPV6 and
Teredo Tunneling. The problem computer - "Keiths" (yours?) - appears to be
setup for IPV4 and Teredo Tunneling.

Your IPV4 is whack too.

Your computer, and the subnet created by the router, appears to be on
10.10.1/24. Yet your DNS server is 192.168.1.254. Now, 192.168.1/24 is a
private subnet, so the only way that this should work would be if your WAN
connects into that subnet.

Yet you say that you were setup by a BellSouth tech, which implies that you have
BellSouth DSL? Who setup Dads?

Are these - Dads and Keiths - truly the only computers in your house (this is a
house, right?)??

OK. First, I uninstalled the IPV6. Booyah. Major difference immediately.
Major. It's almost like I have internet again.

Second. yes, I have Bellsouth internet. But the Bellsouth guy never touched
my computer. All he did was hook me up. They sent me the stuff through the
mail, but I couldn't stay connected. I called them and they sent a tech out.
He spent 2 hours running a new CAT6 dedicated data line, then found out my
problem was a defective modem. He tested the new modem using my computer and
we both noticed how slowly it was browsing. He then connected his computer
to it and declared it to be working fine. He was kind enough to tell me
there was something wrong with my computer, then got in his truck and left.
(I had the last laugh, though--he ran off and left his toolbelt.)

The computer named Dads--I just plugged the external USB antenna in and
started browsing. Nothing has been changed on it at all.

These are the only two computers in use on this network, unless someone has
hacked onto it. Possible, but unlikely where I live. There are 2 unsecured
networks in my neighborhood that I can pick up with irregularity, and most of
my neighbors are quite elderly. I did set up the security on the Linksys
router that I installed.

I'll be honest. I didn't understand the paragraph you wrote about my WAN
connecting to the subnet. Sorry. I'm more of a nuts-and-bolts kind of guy.
I can turn the wrenches OK, but I don't really have a clue what I'm doing.
As I said, I changed the IP to 10.10.1.1 at the direction of the Linksys tech
with whom I spoke.

I do know this, though. I have browsing speed after uninstalling the IPV6.

Thanks.

OK, removing IPV6 probably works because with IPV6 in the picture, your computer
was trying to contact an IPV6 name server, failing, then timing out, and only
then going to the IPV4 DNS server. So that's a good start.

Now, you really should resolve the DNS server issue. My guess is that your DSL
"modem" is a combined modem / router, and it's serving as your DNS server,
192.168.1.254. Then you have your WiFi router connected to that, as a second
router. This is called double NATting, and is a bad idea in the long run.

What make and model is the modem, and the router? Maybe that will give us an
idea if we should stop here, or if we can continue. Of course, it's your
network, but at least knowing what you have setup may be useful in the future.
