@ Son of Science: He said 'IF he brought'
@ Distrance: I've only recently gone 'wireless' so I'll give you my experience of how easy/hard 'setting up' was.
- I get my internet access through VirginMedia Fibre-optic cable and NOT through a telephone line, so they supplied me with a Cable modem - which was originally connected to my PC via a standard LAN cable.
So I brought a suitable WiFi Router that was compatible with 'Cable Modems' - you may need one for 'telephone line' - the one I brought was a 'Belkin F6D4230uk4 Wireless N150 Cable Router'
I followed the quick guide that came with it which basically was
- Disconnect the cable going INTO the cable modem from my PC & plug into one of the ports on the back of the Router
- Using the supplied (yellow) cable, plug into the 'modem' socket in back of router & plug the other end into the cable modem
- Switch on the Modem & wait until it boots up
- Switch on the Router & wait until it boots up
- Switch on PC & insert supplied CD (which will boot up)
- Follow instructions on screen
>> These instruction basically asked 'Have you connected the modem/router up', 'what Country are you in', 'What's your ISP'
Note that in my case My ISP didn't exist in the list of ISP (VirginMedia) but since this company took over from 'NTLWorld' & that WAS on the list - I selected that one instead
Once answered - the software 'transferred settings to Router' - & that was it. I was set up for WiFi & my PC still had internet access
All I needed to do then was type in a IP address on my Web browser (supplied with the router) which had options down the side - one of which is 'Security'
Selecting that & you get a page where you select the type of security you want - the best one to have is 'WEP'.
Once selected you supply a 'password sentence' - which could be anything you like (e.g you could have something like '
If you want to connect supply this line') - & any devices that wish to connect to your WiFi will need to enter the EXACT same 'password sentence' to be allowed to connect to it
As for the range... well the router I have has 'up to 300m' range
I have managed to connect to my WiFi network when I've been outside the house ~80feet away with no problems & 'full signal strength' - so I can't see you having much problems if you're only upstairs
Hope this helps
