TCP/IP configuration.

I bought a Linksys wireless router to use with the laptop at home and can't
get it to work. This is a little lengthy and I apologize in advance.
I am running the following;
Qwest DSL with a Arescom NetDSL 800 modem
When I originally set the system (DSL) up, I connected through the USB port.
To install the router I needed to change to ethernet connection. The only way
I can get the ethernet connection to work is by manually configuring the
TCP/IP settings. Linksys is telling me that I need to have to system set to
auto detect settings but it won't work. Auto detect gives me nothing. I've
tried everything to make it work but it seems that whatever tells XP and the
computer to do it has been changed somehow, and not by me.
My laptop works fine with this connection and modem and will detect auto. I
went into the registry editor and there are differences in the settings
between the two computers. The desktop doesn't seem to have defaults set like
the laptop does.
I'm pulling my hair out on this, not to mention the bucks I have wasted on a
router thast I can't use. Not computer stupid but this one is killing me, any
help is appreciated.

This is not an XP problem. Go to www.dslreports.com, enter the Qest DSL
forum. Check the FAQs that will guide you in your qwest for
connectivity and post questions after reading the FAQs. www.qwest.com
might also have a user help section.

Are you in an area were Qwest has PPPoE enabled? Most of Qwest expects
PPPoA, but most SOHO routers do not support a PPPoA session; so you may be
out of luck. However, some Qwest users have connected with a PPPoE session.

As a test, set up the router to use PPPoE. Enter your userID and password
in the appropriate fields on the router. Try your userid both plain, and as
an email address. If it doesn't work, either way, you probably need to get
your money back on the router; assuming the retailer allows returns.

I've been working on this problem for two weeks and don't think the problem
is with either Qwest or Linksys. Just to see, I installed the router on my
laptop this morning and it went great, no problems with setup and I had
internet connection through the router. Since I was using all the same
hardware the desktop uses, I think it's what Linksys told me, that I need to
have the computer auto detecting TCIP/IP settings.
Thanks for the help though and anything else you can find is appreciated.

You didn't say which model Linksys router you have, but the ones I'm
familiar with have 5 ethernet ports on the back. Four of these normally
are connected to your local PCs and the fifth (the "WAN" port) normally
is connected to the DSL or cable modem. Note that "normally" does not
mean "in all cases."

Just to be clear:

A. You connect your laptop's ethernet port, via ethernet cable 1, to
one of the four LAN ethernet ports on the Linksys, and then connect the
"WAN" port of the Linksys, via ethernet cable 2, to the ethernet port of
the NetDSL 800, and you get onto the Internet.

B. All you do to setup A is disconnect ethernet cable 1 from the laptop
and connect it to the desktop, and you don't connect (unless you
"manually configure the TCP/IP settings").

The ONLY difference between A. and B. is the computer to which cable 1
is connected (e.g., you haven't changed any setup parameters for the
Linksys router).

Where are you doing this manual configuration, and what are you making
the settings?

In the Linksys configuration screens, if you click on the "Setup" tab
and select "Basic setup", what have you selected in the dropdown box for
"Internet Connection Type"?

By the way, is your Arescom NetDSL 800 an MSN-configured unit, or can
you configure the NetDSL 800 yourself via the NetDSL Manager utility?

Hooking directly between the modem and the laptop, I get an internet
connection with the LAN properties/Internet protocol properties/"obtain an IP
address automatically" checked. If I do this when hooked directly to the
desktop computer, I can't get a connection., I have to go back to the
properties box of the LAN connection and under TCP/IP, check the "Use the
following IP address" box and enter all the numbers manually. This is where I
am doing my manual configuration.

I have changed nothing permanenetly on the router, doing so makes no
difference. It has been reset to factory defaults after any changes because
they make no difference. I was able to do the entire setup on my laptop via
provided software with NO input from me. On the desktop, it won't go any
farther than trying to get an interent connection, which it can't obtain.

After multi calls to Linksys and Qwest, they determined that I need that
automatic obtain IP function. The only difference I can see between the two
computers is in the Registery Editor.
Under the following;
MyComputer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{A54CC940-B217-441F-AFEF-549B09D3F10D},
my desktop shows the DhcpIPAddress, REG_SZ, as 0.0.0.0 and on the laptop it's
listed as 192.168.1.2 which is the correct number. On the DhcpSubnetMask,
REG_SZ, it's 255.0.0.0 on the desktop and 255.255.255.252 for the laptop
which is once again the correct number set.
Acording to the COMPAQ help system, those are not changeable numbers (REG_SZ
numbers). Despite that, the Registry Editor gives me the option of changing
them, I'm just worried about screwing up my system. In a nutshell, it seems
as though the laptop has a default set of IP numbers assigned and the desktop
doesn't.

Sean,

This sounds like a variation in DHCP settings provided by the ISP, based upon
MAC address of device connected to the modem. Does your router support
"cloning" or "spoofing"? If so, hook up the modem to router to laptop. Then
clone the laptop MAC address onto the router. If that works, then connect the
desktop to the router, with DHCP enabled.

Or does the modem to laptop only work by USB cable? If so, you'll have to work
with Qwest to get the modem to accept the laptop connected by Ethernet, again
this will be a MAC address issue I'll bet. The Ethernet and USB (with drivers)
ports on the laptop will each have different MAC addresses. Qwest very likely
uses MAC address validation.

Two things: download winsockxpfix.exe (google for it) to repair a
corrupted TCP/IP stack. Also check TCP/IP properties, Advanced button,
Options tab, TCP/IP filtering properties. Make sure all ports and
protocols are Permit All and not Permit None, then disable filtering.

I've been busy, and haven't been able to get back to this thread since
Monday, and the issue may have been resolved. If it has, please post
back with the solution.

If not, from the 6:20 pm post on 10/16, it appears as if the router
isn't part of the problem. Rather, you can't connect your desktop to
the modem via ethernet without manually making the address settings. If
that's so, you're not likely to be able to get much help from Linksys.

Q's suggestion to repair your TCP/IP stack may help. I've never used a
USB network connection, so I don't know what your "network connections"
display might look like. What's listed there? Perhaps you need to
delete your old USB network connection. Or maybe Chuck is right, and
the one successful connection with your laptop has now "locked" your
connection to its MAC address. If this was so, however, I would have
expected Qwest to have mentioned it to you by now.
