ICS problem - LAN works, but no internet connection

[Jhon Smith]

Hello,

I have an ICS problem. After searching on the net how to solve it, I
and am running out of ideas -- help would be *very* appreciated.
Here follows a description of the situation.

I had setup a connection between the two computers and everything
worked. For no apparent reason, one day I had lost internet access
from the client computer. The connection between the two computers is
OK: I can read/write each other shared folders.

The client computer recognizes that I have an internet connection; it
appears in the "network connection" folder. But when I try to connect
to an outside site, I get an "could not find server or DNS Error"
error.

Host: win XP Pro. Internet access works.
Client: win XP home

I have removed all firewalls. I am working with administrator accounts
on both computers.

I have done "netsh int ip reset netsh.log" on both computers, to no
effect.

On the client side, if I go to
MyNetConnection->Properties->advanced->settings, I get a message that
"port already used, chose an other one". This happens for whatever
port I chose; cancel doe not work. I have to manually kill the window
to get out of this.

Here are the ipconfig details:

Hmmm - I thought you had to have the client set to "Get IP Addresss
Automatically" for ICS to work? Also I have found that setting the host to
"Get IP Address Automatically" then enabling ICS works best.

Good Luck

Routing is enabled on the host. Here goes the results of ipconfig

Thats the way it is set up. "Get IP Addresss Automatically" is on for
both Host and Client.

Good - and after you have enabled ICS your host should be set to 192.168.0.1
and non-auto?

Yes, thats how its configured.

Everything between the two computers works fine. But from the client,
I can't go beyond the host.

I have posted the results from ipconfig -all in a reply to Rober L in
this thread -- maby will clarify things for you...

Thanks for trying to help.

No problems Marc - seems to be only you and I left! - I have a similar setup
here and have had trouble in getting it stabilised too - all over now ...

For a start I would suggested removing and reinstalling TCP/IP protocols on
both machines before installing the whole OS again - easier anyway!

My setup is much the same - if you want, I could send you the
windows/properties for my network adaptors etc ...

I wonder if the trouble started after an OS upgrade or software install? -
that might give us some pointers.

I alwready tried that, after searching on the internet. Whell, thats
what I think I did by:
netsh int ip reset netsh.log

For me at least, I didn't do anything speciale. One day it worked, one
day it didn't. I wonder if it could have somthing to with my ISP ? Can
they see that I have 2 computers and try to sell me a more expensive
connection ?

Before reinstalling everything, I will try to install windows on a
spare partition I prudently made on each computers, and see if it
works between "new" windows installations.

Hope you solve your problm to.

I am having a similar issue with ICS ...

I have a Comcast Cable connection for the Internet ... works fine.

I have a peer-to-peer wireless(Belkin) network between the desktop(XP)
and laptop(98). ... works fine.

Configure ICS on the Internet connection and I even see in the
configuration that it will try to share it with my Wireless LAN, but
does not work.

The next day the Internet connection starts to say I've lost contact
with the network and would I like to connect via a dial-up connection.
Things get to flaky with my Internet connection so I restore back to
pre ICS point.

I'm currently looking for some support ... Belkin says talk to
Microsoft ... Microsoft says give me ~$100. I'll probably revisit
the isssue in a few days.

 

[brlarue]

I'm wondering. Are you supposed to have 2 NIC adaptors running.

I'm thinking I need a regular Ethernet card in place along with my
WiFi Network ... so ICS looks to the Ethernet LAN as the main and the
WiFi is a sublan under the Ethernet LAN ... ???

I saw some instructions on some Networking Help site that showed a
dropdown when you click on ICS and then there was a second drop down
list below that where the example showed a WiFi in that list. I do
not see a dropdown list when I click ICS ... and all I have is the
WiFi network and of course my Broadband connection

Hmmm

You tell ICS which connection to share by enabling ICS in that
connection's Properties | Advanced settings.

If your computer only has one other LAN connection, it will
automatically use the other one for the home network, without asking.
If your computer has two or more other LAN connections, it will ask
you which one to use for the home network.

Thanks for the info ...

I still have issues with ICS.

If I turn on ICS and do exactly as it says I end up with a flaky
Broadband connection that keeps timing out and I no longer have file
sharing on my WiFi network.

I have tried several variations with ICS turned on with about the same
results. I'm sure one day I'll get it to work, but I'm guessing it
will have to be some magic, not found in the normal places, procedure.

PS - If anyone out there has shared their Broadband using ICS on a XP
with a Belkin WiFi network with a Win98 Laptop as the client ... pls
respond.

You didn't give any details of your ICS setup, so please forgive me if
I make suggestions that you've already tried:

Make sure that you're enabling ICS on the right connection: the one
that connects to the Internet, not the one that connects to the home
network. So in your case, enable ICS on the broadband connection.

That will automatically set the IP address of the WiFi connection to
192.168.0.1. If the other wireless computer(s) use a different IP
subnet, you'll have to change them. The easiest way is to run XP's
Network Setup Wizard on the other computer(s). If your WiFi network
is Ad-hoc (computer-to-computer), that's all that's needed.

If your WiFi network is Infrastructure (uses a wireless access point
or router), you must:

1. Disable the wireless access point's or router's DHCP server, and:

2. Connect the host PC to one of the router's LAN ports, not to its
WAN port.

To protect your network from Internet hackers, enable XP's Internet
Connection Firewall on the broadband connection. To allow file
sharing, disable the Internet Connection Firewall on the WiFi
connection.

I'll follow your latest suggestion and post the results.

I was enabling ICS on the Desktop, which is connected to the Internet
via a broadband connection. I'll post the ipconfig data from both
machines and how I enable ICS.

This is continuation of issues with ICS and wireless connections ...
Host is Windows XP Pro ... Client is Windows 98SE
Both have Belkin Wireless Adaptors ... connected Peer-to-Peer

Here is the IPCONFIG info from both PCs.
I notice that DHCP is OFF on the HOST and ON for the Client(Laptop)
Also I notice that there is Lease Obtained info on the Client info.
I don't know if that's a Broadband thing or ?
I turned off all my Firewall protection and it is still unable to find
a server when trying to connect from the client.

Amazing ... I have made some progress on this ...

After I had things set up as best I could determine on both the Host
and Client WiFi Adapters I ran the Network Wizard again and told it to
work it's magic for a home office network. It went thru it's magic
and then said it had problems. I turned off the Firewall setting on
the Host/Desktop WiFi Adapter and ran the wizard again. This time it
completed successfully.

Question? ... If the Wizard fails where do you look for the possible
errors ???

I can ping the IP address of the WiFi Adapter on the Desktop. ... from
the client Laptop

I can ping the IP address of the Client/Laptop from the Host/Desktop.
I can also ping the Default gateway for the Broadband Connection from
the Client/Laptop. The Default Gateway on the Broadband Connection
changes each time I turn on the Broadband modem.

I can see the shared directories and printers on the Host/Desktop from
the Client/Laptop. The Client has Lease type information ....

I just can't see the Internet ... I get dns page not found ... on the
client.

I notice on the WiFi adapter on the Host/Desktop that it does not use
DHCP and there is no Default Gateway ... So I'm wondering how the
networking makes the leap from the WiFi network to the Broadband
network.

Is this the problem ???

 

[brlarue]

OK ... more info ...

I can ping the IP address for yahoo.com or any other site in the
Internet. I just go to them with the domain name ... e.g.
www.yahoo.com ... so what is wrong with this picture? Something with
DNS on the client, but ? I clicked on ... use DHCP for WINS
resolution and I tried with that clicked off ... either way ... no
luck.

 

[brlarue]

Well I have the network working and I can ping any IP address, but it
can't find names. I have tweaked the DNS settings on the client with
a variety of possiblities, but it still gets the "host unknown" msg
when I try to ping say www.yahoo.com rather than it's IP address.

 

[brlarue]

I finally got the ICS with my peer-to-peer working last night. The
last thing I did was turn off the McAfee Firewall service on the
HOST(XP) machine. Now it works. For all the pain and suffering I
went through I would reccommend that you not bother with ICS. I would
go with a WiFi Broadband Router. Thanks for the help. I didn't
really get the complete answer via this thread, but by reading some of
the other threads and their links to various sources I was able to
piece things together.
