Sharing Internet between new Desktop and Laptop

One good way would be to invest in a Netgear DG834G Wireless ADSL Modem router.

This would replace the blueyonder modem with the router. It would then be able to connect to the computers through wireless OR cable.

Would need to make sure both computers are wireless enabled. If not you can get hold of Wireless PCMCIA cards for laptops, or wireless PCI cards for pc's... If you don't want to get your hands dirty with PCI cards you can get a USB Wireless Adapter but don't expect super fast speeds with it....

When setting it up make sure windows firewall and software firewalls are turned off on both computers otherwise it will block the connection and cause problems. Nearly all router problems are caused by this

Good luck, if you need any more help I'm just a PM away.

Right then, for a start an ADSL modem would be good but it wouldn't work Blueyonder uses 'real' broadband as I call it and your connector for it is an rj45 or a USB cable.

Lets start right now by saying we are not going to get rid of the blueyonder modem, this is a bad idea and there aren't that many decent integrated cable routers, as the cable that comes out of the front of your house is coaxial cable

This is what I thing you should do. You need to purchase a Wireless CABLE router.

There we go, that one will do perfectly for what you need. Then you need to purchase a patch lead (you should allready have one if you have a cable modem. The patch lead is going to be used to patch your desktop PC into your brand new router! As your laptop allready has a wireless thing on it there is no need to purchase anything extra.

Before we start we need to do a step for later. Goto dos and type ipconfig /all and note down the mac address of your CABLE MODEM. You will see why later.

Once the router installed, log on to both the main machine and the laptop, find there network connections (Start - My Network Places - View my network connections) right click on the connection, goto properies, click tcp/ip and goto properties and change it to obtain an IP address automatically and obtain a dns server automatically. Thats your two machines setup.

Using steps in your router manual, log onto your router from the desktop machine, and configure DHCP from within the router config page (It will tell you how to do this in your manual)

Now you need to configure the router so that It will 'route' your internet. Go onto the correct page as stated in the router manual and choose the correct connection type. Just to save you future reference blueyonder does not have a static ip, but it assigns ip's to customers, I can't remember what the connection type is but I will find out when I go home. This is where the mac address comes in, the servers at blueyonder will ONLY authenticate you if you have the correct mac address for the cable modem, so use the mac address you wrote down before and put it in the correct place, which will probably be on the screen you were just on.

Once this is done, it should tell you somewhere that the router is sucessfuly sharing the internet (probably on the main screen of the router config page) proceed to the wireless config section. Using advice from the manual choose an SSID and an encryption type, and put in an encryption key and right it down. Oh and for added security you can use mac addresses so that only machines with the mac addresses you enter can connect to the network, mac address can be found by going into dos and typing ipconfig /all its the one that looks like this 00-34-ff-56 etc... you want to choose the mac address from the network card section (the one that is active on that machine) do this for the laptop as well and find the mac address section on the router and add the mac addresses and bingo your security is sorted

Restart your router.

Once this is done, on your laptop do a search for wireless networks, and select your network and connect to it. Now then, go back to the desktop machine and log back onto your router, using advice from the manual again setup the hardware firewall that will be on your router.

Restart all the machines and bingo you have a wireless network

:T

EDIT 1) You won't need the blueyonder drivers that they supplied you for any part of this

Oops my bad.. thought blueyonder was adsl

*kicks self*

Its just blueyonder is an ISP like BT, AOL or NTL. Its there cable broadband Very much like NTL as far as i am aware.

It's possible to share a connection between two machines, all you'd have to buy is a wireless adapter for the desktop. The wireless adapter could be PCI, which you have to open the PC to install, or USB, which just plugs in. It's reasonably simple to share a connection this way but the machine with the modem obviously needs to be on whenever you want to browse.
