What is the way of getting net connection with both systems?...

try wifi connection of your laptop but buy router with wifi connection.

It is very simple buy a wireless routere then youcan run your laptop on wi-fi and desktop on the cable , router willcost you about 1500p. and that is it.

I have similar problem with you. We have desktop but I prepare to work on my laptop so I used a cable to connect my laptop from the cable of my desktop. I have plan to buy a router so we can enjoy wifi.

It would be best for you to buy a good wired and wireless broadband router here. There are some models that has a modem built-in which you can lessen some hardware and additional configuration that comes along. Just remember to check your requirement before deciding which type of router would best suit you. I believe you will need to connect your PC via wire to the router while your laptop would be the latest model that is WiFi enabled which means you can connect wireless with this gadget. Router is best for the job being that the access speed will not be compromised or affect the overall performance when both are accessing the internet.

The cost of hardware will depend on your existing hardware. For example the kind of connection you're already running, DSL, Cable, ADSL etc etc . You may just need a wireless router if your internet and computer is able to go wireless. You could also just use a router and plug your modem and then machines into it. They range from anywhere like £20 for something cheap - £90 or more (generally) Using a simple cross-over cable is a very cheap alternative. Obviously it has much bigger cons though A: Cable being one length after its setup B: Main computer (internet one) ALWAYS has to be turned on C: Not always reliable, but then again what network is Heres a simple guide to it if you wanted to try it out. Bit old but its should be pretty much the same today. http://www.hardwaresecrets.com/article/How-to-Build-a-Network-Using-a-Cross-Over-Cable/426/1 Page 3 is when the author starts setting it up.

A laptop is designed to be moved, so I would avoid to use a crossover cable if I was you. The easiest solution would be to buy a wifi router and to connect the desktop to the router with a cable, and the laptop with wi-fi. If it is too expensive for you, you can buy a wi-fi card for your desktop and use the desktop as a hotspot -- there are software available for this -- to connect your laptop to the internet, but with this solution the desktop has to be turned on to be able to have an internet connection on the laptop.

Why not make us of a wifi connection? The cost of the modem depends on the brand and quality.

Usually,laptop has wireless net card,so,I guess,the easiest way to connect them is to buy a wireless router,you need an additional cable to connect the new wireless router and your modem,both of them will share the bandwidth via router.
