Hi, My very first post. I hope someone can help I've currently got my 1.8 Sony Vaio NR laptop connected to an O2 (thomson) wireless box, running VISTA. Interface type: 802.11b/g Actual Speed: 54 Mbps Band: 2.4G HZ Bandwidth: Up: 1,057 kbps Down: 4,480 kbps I'm waiting on delivery of a new PC. Intel Core2 Duo processor E7500 2.93ghz 3gb DDR3-SDRAM 500GB sata 3G hard disk drive Nvidia Geforce G210 card Intergrated 10/100/1000 Gigabit Ethernet Lan. Now....My new pc is equiped with Windows 7 BUT doesnt have a wireless card, so i'm in need of a card as soon as possible but i'm unsure of which card make to buy, which is compatible with my computer AND O2 router, and i'm also unsure of which are compatible with Windows 7? Any help would be very much appreciated.
