I had a wireless connection for a few months now. It can use both 3G and Wi-Fi, but I am using 3G right now. However, it is really bad and drops all the time. I use it for a mobile device.

I was now thinking of buying a Wi-Fi modem too and of using it for both my mobile device and my laptop (I normally use ADSL2+ for my laptop).

I know this question is pretty simple, but I never had Wi-Fi before.... Sad So after I buy the Wi-Fi modem, what do I do? Just connect it to my laptop and mobile device, or do I have to set it up in one of the two?

Clarification Request
Sorry but please give an example of a WIFI MODEM.

I think it's the usual MIFI or other cellular to wifi thing but those have the same issues here.

I saw an ad...

... on the window of a shop, but I don't know the brand or anything. I was on the bus. I can ask for more information if I go by or email them.

What is internet

I think key question is which connection you want to use for your internet.

You have 2 from what I can tell, 3g and ADSL.

Either will work. The simplest is place a normal WIFI router on your ADSL connection and have your PC and other device use this router. Your PC can use a cable if you like.

The harder one would be if you wanted to use the 3G connection as your internet. You need a very special router to do this.

The WIFI setup is the same and is not hard just follow the instructions, mostly its set a SSID key, select the security and set the secuirty keys.

I was thinking...

...of using the ADSL connection for that. Apparently I will also need a key to unlock WIFI?

And once it is all set up, does my laptop have to be on for WIFI to work on my mobile device? I suppose it has, if the mobile device has to use the router.

They have a router for only 19 dollars where I am, so I thought I could try it, as 3G is not always the best, as I said in my OP.

Thank for your reply!

I will be very simple in case there is a language problem.

Mobile device can use WIFI.
Laptop can use cable OR WIFI.

Most ADSL routers can run both ethernet and WIFI at the same time.
