Hi Folks, maybe someone here can help me before I pull all my hair out.

I have a small home network as follows:

1 pc running Windows 7, and connecting to the internet with a CellC speedstick

1 pc running Windows XP

1 laptop running Windows 7

1 Mega 100WR ADSL router used as a hub to connect the 3 machines. The ADSL is no longer used; the two pc's are connected to it by ethernet cable and the laptop via wireless.

So far, so good; all three machines can see and ping the other two, as well as ping the hub (10.0.0.2)

I have set his up as a "work network" in Windows 7; I cannot use the Home group facilty as one machine is on XP.

Now, my problem is that although the main machine connects via the CellC speedstick to the internet without problem, and the connection is set up for Internet Connection Sharing (ICS), the other two simply cannot see the connection and obtain internet access. :mad:

I've spent the past few days on Google, disabled and uninstalled and then re-installed all the connections, verified that IPv4 is activated, that Client for Microsoft Networks is activated.
Should this setup be possible? Any idea how to get it to work? :confused:
 
ICS requires the primary machine to use 192.168.0.1 probably as IP address,however your old adsl router is giving out IPs and itself as the gateway,which means you'd have to reconfigure the router to either hand out your machine as the gateway,or entirely disable DHCP and configure all your machines manually

Frankly the level of pain required in correcting this - while entirely doable - can cause many headaches and is not really worth it
I'd rather just take out R380 bucks and get a router like this
 
Thanks for your response. It seems that your suggestion to use a different router will be the way to go.
May I ask: the specs for the router that you mention includes 4 10/100Mbps LAN ports, so I'll still be able to network my three machines locally for transferring files, sharing a printer and so forth, in addition to sharing the 3G connection?
 
Yep,thats why I suggested it ;) should be very little adjustment to the new setup
 
As far as i know when you activate ICS the Ip address on the machine sharing the internet will automatically be made 192.168.137.1. The problem now is that all the other machies are still on the Ip range which the Telkom router has given them i.e. 10.0.0.2-10.0.0.254.

So.. unless you are going to buy another router to share the CellC modem you will have to config the modem to allocated IP addresses starting from 192.168.137.2-192.168.137.254, the routers ip must also be changed to be within the range (just not 192.168.137.1). After which you will have to change each individual pc so that its default gateway is 192.168.137.1.

But like PsyWulf said buying a modem who can share the connection makes the most sense and is not too expensive.
 
Okay, there's more than one way to skin a cat: What I eventually did was to install a proxy server on my main machine and configure the others to use it - quick, easy, does all I need, and it costs nothing. I rest my case.
But thanks anyway for the help and suggestions, I've learnt quite a bit in the process.
 
Ugly solution,but hey if you're happy it's all good ;)
 
I'd like to piggyback on this thread if ya'll don't mind.

Would setting it up like Psy says work with OpenElec (linux) using Samba? I tried connecting my HTPC the other day and thought screw this, I wasn't in the mood to struggle with IPs :)
 
why do you want to use samba?
If you have linux it is pretty straightforward although you can download packages which make things easier.
Create a default route out your 3g interface.
use IP tables to route incoming traffic and NAT to 3g interface or other routing software
start up DHCP deamon on linux box and set an ip range to give out with the box IP as the default gateway.
Turn off DHCP on your router or other layer 3 device.
all computers that connect then just obtain IP address automatically and there we go.
linux is so much better than windows when you actually wanna make the box to do stuff
