Few laptops come without a wifi card. Why did you add such a card? Why not use what the machine came with?
Also, to avoid repeating the same advice for each post we have a sticky post with preferred router settings. Your post doesn't tell how your setup differs.
i recently got a new laptop, and a Netgear wireless internet card.
after several attempts, im still struggling to manage to maintain an internet connection to the router in my home for longer than 4 or five seconds, before the wireless card starts scanning for a connection all over again, and repeats this cycle.
this is not a problem that occurs with any of the other laptops in my household, only mine. and even then it only happens with my router, not in my other family members homes.
Does anyone have any idea how i can solve this?
