Re: Cannot simultaneously share DSL connection

Hi
Did you typed the ID and PW of the Internet provider (ISP) into the WAN DSL
menu of the Linksys, and uninstalled the ISP's PPPOE software dron the
computers?

PROBLEM: We cannot simultaneously share a DSL internet connection on our
home network.

We have 2 computers in a home network connected with a router. Each
computer can see files on the other computer. The newer computer also
prints
through the other computer, because the printer has an old-style plug.
Each
computer separately can connect to our DSL server and access the internet
and
email. However, we can never connect simultaneously. Neither computer
can
access the internet or email while the other computer is connected.

When Computer 1 is connected to the internet and Computer 2 attempts to
access a webage, Computer 2 gets a message that says "Internet Explorer
cannot display the webpage." When Computer 2 is connected and Computer 1
attempt to access a webpage, it gets the message, "The page cannot be
displayed."

HARDWARE & SOFTWARE

Computer 1: Dianne
HP Pavilion a1630n, running Windows XP, Media Center Edition, Version
2002,
SP2
Newest computer, purchased 10/2006. When the problem first began, we had
a
different computer. Getting a new computer made no difference in what
happens when we try to share the internet connection.

Computer 2: Nancy
HP Pavilion 504n, running Windows XP, Home Edition, Version 2002, SP2

Anti-virus and firewall: PC-Cillin Internet Security 2006 (by Trend
Micro)
on both computers. Windows firewall is turned off at the Windows Firewall
screen.

DSL Modem: Westell C90/610014-06 provided by ISP

Router: Linksys BEFSR41 vers 4.1
________________________________________________________________

HISTORY OF THE PROBLEM:
This problem began last summer when we switched from a dial-up ISP to DSL.
With the previous dial-up connection, we had used a Linksys 5-port
workgroup
hub to connect our network. One computer connected to the internet as
host
and the other computer was able to simultaneously access the internet.
This
worked fine for several years. The hub did not work with DSL. Both our
new
ISP and Linksys told us we would need a router in order to have internet
sharing on a DSL connection. So we purchased and installed the router.

Several things happened at about the same time as the change to DSL.
Computer 2 was finally upgraded to SP2 (from no service packs) at that
time.
Also, PC-Cillin had just been updated to the 2006 version on both
computers.

WHAT WE'VE TRIED:
We started with Linksys, because our first sign of a problem was the
router
setup disk. It goes to step 6, checking the router's status, then it
hangs
up on "checking your computer settings." It asks for a password, then goes
back to "checking your computer settings," then asks for the password
again,
and on and on in an infinite loop. We spent long hours exchanging emails
and
in live chats with Linksys support. Linksys support had us download
software
to reconfigure the router. The software could not "find" the router, even
though the computer was using it to connect to the internet. Next,
support
sent instructions to manually configure the router. We can't get past the
first step, which is to enter the router's IP address 192.168.1.1. That
always results in a "page not found" error. Support suggested hard resets
and clearing browser settings before the configuration, but 192.168.1.1
still
cannot find the router. Finally, Linksys support decided the router must
be
defective. We exchanged the router. The new one does exactly the same as
the old. We have not recontacted Linksys because they don't seem to have
a
solution to offer if typing in the IP address gets no response.

Initially, we could not make our home network work at all. We have
gradually worked through various problems, such as with the registry, and
have gotten the network to the point where everything is shared except the
internet connection.

We suspected that the anti-virus software could be causing the problem, so
we did the scary experiment of turning it off on both computers and
attempting to access the internet. There was no difference. PC-Cillin's
firewall setup screen has an option for "home network" profile, and that
is
what we use. We called PC-Cillin, and they said that if turning off the
software doesn't eliminate the problem, then their firewall is not the
cause.

We've run the Network Connection Wizard a zillion times on both computers.
We use the second option, connecting to the internet through a residential
gateway or another computer (although we've tried the first option too).
Running the wizard always turns on Windows Firewall, so we've learned to
turn
it off again after running the wizard.

Computer 2 initially had several anti-spyware programs loaded on it.
Those
have been uninstalled, in the hope that they were somehow setting up a
firewall. No difference.

Since we've been banging our heads against this brick wall periodically
for
months (we stop when it gets too bloody, then try again) we may have
forgotten what else we have tried unsuccessfully.

We don't know what else to try. Can anyone help, please?
