Hi,

I've recently bought a new wireless routeur (Belkin wireless G+ Mimo router F5D9230-4 ver. 3000fr). I also owned a wireless notebook network card (model F5D7010 ver.1314uk) which I bought a few years ago.
I recently decided to buy a more modern card thinking that it would improve the performances of my connexion (model F Card model F5D9010 ver. 3000fr).

My laptop is running on windows xp SP2

My problem is that I am getting a much faster connexion (factor of 2 to 3 in download) with the old card than with the new card although I used TCP Optimizer on both of the cards.
Here is what I get with TCP analyser for both cards

Card model F5D7010 ver.1314uk:

Could someone tell me what is wrong with the new card? Why can't I get better performances with the new card or at least as good as with the old card? This is crazy for me

Thanks in advance for your precious help
