I'm stumped trying to share a connection

tinofapples

Here's the plan:

I have BB with Vodafone at home, the modem/router is downstairs but my desktop is upstairs in the house. I have wifi on my laptop and have created a LAN between my laptop and my desktop so that I can share the internet connection. Now I can't for the life of me use the internet on the desktop even though the LAN seems to be connected fine.

Any suggestions or help please ? I have had a look at youtube tutorials and read some threads here but can't get it:mad:

Can you post the results of 'ipconfig /all' for the laptop & desktop (preferrably while the laptop still has Internet access). How are the laptop & desktop connected, e.g. via a switch, a cable?

tinofapples

Thanks for the quick reply, I've got them connected by cable. I've run the ipconfig/all on both machines.

How do I copy and paste the results here ??

Simplest way (i.e. shortest for me to type) would be :

1. Redirect to a text file. For example 'ipconfig /all > c:\ipconfigfile.txt' redirects the output to a file in 'c:\' called 'ipconfigfile.txt'. Open the file, copy and paste.

Your laptop's ethernet port has no IP address. You've got it set to autoconfigure but as far as I know you'll need to give it a static IP address. Check that part of whatever tutorial you were following.

tinofapples

Now I am all fuked up. The IP addresses cannot be the same but what then do I use.

The TCP/IP properties of the desktop read:

IP address 192.168.1.1
Subnet Mask 255.255.255.0
Default Gateway 192.168.1.2

What do I need to make these on the laptop to allow them to be "match" ?

I've tried following so many tutorials (Some not even in English) that I don't know which one is good and which isn't.

Thanks again for your time BTW

Hang in there! Can you post one tutorial that you've been following? That might make things easier to follow. Alternatively, just stick with the Microsoft one here for the moment.

Anyway, there are 3 important IP addresses :

Router (192.168.1.1)
Laptop (192.168.1.2 obtained via DHCP from router)
PC (192.168.0.x obtained via DHCP from laptop)

When you enabled Internet Connection Sharing on the laptop's wireless connection, the laptop's LAN connection is assigned an IP adress 192.168.0.1 (as long as it's connected to something that is). This 192.168.0.x network is a separate network from the 192.168.1.x LAN that the router and the laptop's wireless are using.

So the laptop LAN connection & the PC are one network and the laptop's wireless & the router are on another. Kapeesh?

So, if you're still awake, undo everything you've done, step through the Microsoft tutorial and see how you get on.

Why not just add a wireless usb dongle to the desktop? It would be far easier.

You have set the desktop to a static address of 192.168.1.1, this is the same address as your modem and so therefore there is no route to the internet as there is an IP conflict, give the desktop a static address outside your DHCP pool and try again. It might work but it would not be the solution I would favour!

Do what munster cycling said. I don't understand really what way you have this setup. If you have ticked the box for internet connection sharing on either of these systems, I would turn it off.

Your laptop has a wireless connection but your PC does not (from what I can gather from your ipconfigs). The laptop is going out directly through the router. The PC is not going anywhere. Is the PC connected to the modem via an ethernet cable? If so change take off the internet sharing option if its on, set DHCP to yes. That should do it really.

Read the OP then

"...the modem/router is downstairs but my desktop is upstairs in the house. I have wifi on my laptop and have created a LAN between my laptop and my desktop so that I can share the internet connection."

What they want to do is access the Internet from the PC via the laptop. It's doable but just needs to be done carefully.

JDxtra

Errr, again - as MunsterCycling says - buy a USB dongle for the desktop (<€20). Job done.

You don't need to setup fixed IPs, have the laptop on and connected, or setup internet connection sharing etc etc. Let the router issue the IPs via DHCP.

Surely this achieves the same end goal, only better.

Yes that's an alternative way of getting Internet to the PC and it might be what you or I would do.

However the OP has asked specifically about how to do Internet connection sharing.

JDxtra

Yes agree - but this may be because the OP was unaware that a simpler solution is available.

MunsterCycling

Why re-invent the wheel, I deal with situations like this every week and tbh just get a USB dongle and your life can go on... LOL

In response to you all chaps, I know I can buy the wireless dongle but I would ideally have liked to do things the other way just out of curiosity. Ah well maybe I'll just but the dongle

Yes but from the ipconfig and the OPs post, it doesn't say how the PC is physically connected to the laptop. Creating a "LAN" can be done via cable or wireless so I don't know what the OP has tired to do.

The laptop has a wireless connection to gateway 192.168.1.1, the ethernet connection doesn't have an IP in the same subnet as the defined gateway so doesn't look like its connecting to anything.

If the PC and laptop are connected via a hub/switch/crossover cable (which hasn't been said yet) then the PC should be set to obtain an IP over DHCP. This will give the PC an IP address, subnet mask and gateway that will work.

The PC is phsically connected through the ethenet cable (LAN). BTW I have previously tried a Belkin G Plus MIMO adapter on the PC and it's rubbish.

Tinofapples, have you tried that Microsoft tutorial yet and if so how have you got on? What you're trying to do is an interesting way of bringing Internet to another computer so it'd be good to get it working.

Dude ........ with a little bit of dickeying about got it sorted handy enough, believe it or not uncheckking the ICS box and rechecking it again seemed to do the trick along with "Obtain Ip automatically"

Working now anyway, thanks a million for your time in particular and of course all other contributors !!
