View Full Version : Internet Connection Sharing Doesn't Work, but File

I am running a peer-to-peer network, using a Netgear USB adaptor on the host and a Netgear PCMCIA card on the client.

If I run the networking wizard on the client, it sets the IP to 169.254.155.150 with a subnet of 255.255.0.0 which I believe to be a (deliberately) invalid address
(according to Netgear's Tech. Support) that is generated when there is a poor connection.

However, if I manually configure the IP addresses as follows, the network will allow me to share files between the two machines:

IP: 192.168.0.2
Subnet: 255.255.255.0
Gateway: 192.168.0.1
DNS: 192.168.0.1

With this configuration though, Internet Connection Sharing simply refuses to work. I have followed the MS Help & Support Tutorial for networking, and doesn't solve the problem, only telling me what I already know.

Does anyone else have this problem, and any insights into it would be greatfully appricated.

Incidentally, everything (file and internet connection sharing) did work before I took the laptop on vacation, where I was plugging it into a hard-wired ethernet
network, although I don't see how this would affect anything. I have even gone to the extent of repairing Windows in case of registry errors. When connected to
the hard-wired network, it also gave Internet Connection Sharing problems (at initial connection) but after several refresh attempts in Explorer it started to work.
However, this practice does not work for the wireless setup.

Using the ipconfig /release and /renew commands report that the DCHP server is unavailable. I know (well, think) that this is a router function, but as the network is peer-to-peer surely Windows would assign an address in the 192.168.0.x range, or whatever?

Any help really would be appreciated! :think:

Does the laptop connect to your network off the router or via the PC that is connected to the internet?

Although you don't say what operating systems your using,I'm going to take a guess with XP,make sure you have LMHosts lookup unchecked in the Local Area Connection

The laptop connects to the PC which is connected to the Internet (there is no router).

I don't know why by OS came up as "Pleads the 5th" when I set it to XP-HE when registering. Both machines have this OS. I have now disabled LMHosts (that image helped big time) on the client. What are LMHosts (never heared of them before)? I presume that I ned to do this on both machines (I've done it anyway)?

Do you have two Network Cards in the client PC, one connected to the internet and the other connected to your laptop? If so, have you tried checking the NIC connected to the laptop to make sure it has not gone bad?

Crazily, I went out and bought a new Netgear NIC (PCMCIA card) for the laptop and USB NIC for the desktop (previously, they were both Belkin, which are notorious for XP-incompatibility), only to suffer the same problem!

Like RB asks Do you have 2 NICS in your desktop pc and 1 NIC in your laptop


169.254.155.150 should be your internet IP on the desktop pc

this should be your network IP for laptop

IP: 192.168.0.2
Subnet: 255.255.255.0
Gateway: 192.168.0.1
DNS: 192.168.0.1

should be network IP for desktop pc

IP:192.168.0.1
subnet:255.255.255.0 (sometimes that last .255 will read .254 nothing to worry about)
gateway and DNS should be left blank

In addition
make sure that:
1. all PC's on the LAN have the same Workgroup name...
2. each PC on the LAN has a unique computer name...
3. all PC's on the LAN have their adapters (NIC's) installed properly...
4. all PC's on the LAN have their clients (Client for Microsoft Networks)installed properly... and
5. all PC's on the LAN have their services (File and Printer Sharing for Microsoft Networks) installed properly

If it were my box,I would get rid of USB and go with a regular NIC

When you say NICs are you referring to PCI cards?

In that case, I only have one ISDN card, and no others. I used to have a Belkin PCI card which I got rid of (because I thought it was at fault). I am now experiencing the exact same problem with USB!

Those are my exact IP settings. I can pefrom file sharing, but not ICS.

Has this configuration ever worked? I always thought you had to have two NIC's, Network Interface Cards, in the client PC with this type of configuration. One NIC connects to the internet and other connects to the host PC, laptop in this case.

The configuation which did work at one point was:

Belkin PCI Wireless Network Card (Host)
Belkin PCMCIA Card (Client)

This stopped working, and was replaced with:

Netgear USB Adaptor (Host)
Netgear PCMCIA Card (Client)


When the internet is accessed on the client, the network activity symbol (WinXP) in the notification area on the host flickers to indicate activity, and the packet count increases accordingly. This leads me to suspect the problem is with the host and not the client.
