Hi and Thanks everybody for your help.
All the offer ones on pc world and dixons etc were out of stock.
So got one at Argos just now, a Neatgear one on offer for £49.99 and the usb adapter (although i dont think i need it) on offer for £9,99 instead of £29.99 as i bought the router with it.
If i dont need it then i can take it back for refund. I dont think there is anything plugged into back of my desktop pc, ie some sort of aerial i may need, so will phone Medion helpline on Monday to see if i need anything, although it is already wireless enabled.
Getting there slowly! Think i will stick with the 2meg when they install the cable modem later on. At least the Netgear router will be able to be used through the tv drive box for the moment though (fingers crossed!!)
Have just ordered a Pizza for tea because this has took me ALL DAY..will need a lie down now.
My son is playing live on xbox 360 on a neighbours unsecured network so at least he is happy for now.
Thanks again, and i will be back later with up update, or even some more help!!
Cheers
Lorraine
