Do you have the card and the router set to N mode and not mixed?

are you sure already download/update correct firmware for your router. i think your d-link router it's not support if you change the G firmware. coz the type of your d-link only support for N.

 

 Peace

how do i set my card to n? my roommates are both running n fine but i'm still running g, theres aren't dell

i'm still confused on y i'm not getting n speeds, the router works for my 2 roommates and says mode n for them in the router panel but mode g for me. i did update to the newest fireware and i'm pretty sure the 1500 card should work for n, if it doesn't then i think dell owes me my money back cause i upgraded it after the service rep recommended it

Read this I think the prob is that the 1500 is dual band and the router is not so it falls back to a slower speed..
