Hello Could some one tell me what the difference between Wireless-G LAN card and Wireless-N LAN card ? and which one is better? thank you in advance
The short answer is that Wireless N is faster than Wireless G, but you need to have access to a Wireless N router to get Wireless N speeds. http://compnetworking.about.com/cs/wireless80211/a/aa80211standard.htm Wireless G is faster than most broadband connections, so unless you are moving files across an internal network, the difference is moot.
