Windows XP won't connect to Internet through router WAN port

[Guest]

I have a frustrating problem. I just installed a NetGear WGU624 router. Two
Windows XP machines (I will call them M1 and M2) are connected to the LAN
ports, AllTel DSL is connected to the WAN port. AllTel requires PPPoE, so I
configured the router using the user name and password. Both machines have
internal 10/100 ports, and are configured for tcp/ip, MS client for networks,
MS file sharing, and the QoS packet manager. M1 and M2 see each other on the
network and file sharing works fine. M2 can access the internet through the
router WAN port with no problem. However the identically configured M1 cannot
see the internet.

When IE is started it shows the browser searching for proxy settings (normal
for AllTel), but then a page not available error message appears. It acts
like the user name and password are not getting passed to AllTel from M1, but
are getting passed by M2 and/or the router. I have tried every obvious and
not so obvious fix, with no success. My questions, is the router responsible
for passing the userid and password, or do both the router and the individual
machines have to “sign-in� If M1 has to pass the user info to AllTel, where
in XP do I find a place to put the logon info? All I see is logon info for
dial-up and not broadband.

Is there something else that might be going wrong? I shut down the Windows
Firewall and Norton Firewall on the machine before trying to connect. Also,
the internet connection was working before the LAN was attached. Plus I have
a couple other small LAN’s working fine with the same router / system
combinations. Any help would be appreciated.

The router passes the userid and password to AllTel. The computers
don't -- they get their Internet connection by Ethernet from the
router, and they don't even know that the router's Internet connection
uses PPPoE.

M2 shouldn't be searching for proxy settings. In IE, click Tools |
Internet Options | Connections | LAN Settings and clear all of the
boxes in that window. Reboot and try Internet access again.

If that doesn't solve the problem, compare the TCP/IP settings on M1
and M2. Right-click each computer's LAN connection and click Status |
Support | Details. They should show the same subnet mask, default
gateway, and DNS servers, and they should have different IP addresses
in the same subnet.

Thanks - I will try those suggestions in the morning - they are exactly what
I needed.

Steve - I tried the suggestions but still can't get IE to connect to AllTel
on the one machine. The router shows normal traffic from both machines except
for IE traffic from and to M2. The only difference that is left between the
machines is the MAC address of the LAN adapters. AllTel says it does not
track MAC addresses, but they say the Orckit/Fujitsu modem has been known to
block MAC addresses. I have 2 other Fujitsu modems with multiple machines
that don't block, but that is the last item for this setup that makes any
sense.

My question - should/can I spoof the MAC address for M2 to match M1?

Thanks, Paul

Power cycle the modem, router, and computers. Remove power for a
minute, the repower the modem. When the lights stabilize, power up the
router. When its lights stabilize, start the computers. This should
clear the modem's MAC table, register the router' MAC as the log-on
computer (if you set username and pw in the router web configuration
page!) and then allow both computers to have internet access. Both
computers should have IPs like 192.168.1.X or .Y.

If this does not work for the problem computer, google for the app
winsockxpfix.exe. This will fix the layered services that if one is
corrupt, will prevent internet access.

If there is still a problem, look into TCP/IP filtering properties in
the Advanced TCP/IP properties and disable filtering.

Thanks - I finally got everything working by combining Steve's and your
advice. The regular power off, rest, power on cycles did not work. I let the
modem rest 4+ hours to clear any MAC entries and then did a hard reset on the
NetGear router, then everything worked. I think using the reset button on the
router and the modem clearing (Fujitsu/Orchkit modems apparently are bad for
MAC problems) got things straightened out. The hard part was that everything
was normal when viewed using the router browser. Thanks again to both of you
for fixing the mess.
