Now I am not sure if this is a Vista problem or a Intel 4965agn issue but I have only encountered it in vista/windows7.  When I download a file say Windows 7 beta I get to about 60 odd MB and the connection drops off.  Not completely but I lose internet access but still have local access.   To resolve it I need to turn off and back on my wirelss connection.  The other way to overcome this annoyance is to plug in an ether cable and disable wireless and all is good.  This happens no matter what download and around 60MB seems to be the coommon denominator. 

I have a HP DV9612TX which came preloaded with vista ultimate and also has the Intel 4965AGN network card.  I have SP'd  and updated the Intel drive from the Intel site, The windows update and from HP and each time have the same problem.  I downloaded Windows 7 last night hoping the problem would be resolved but alas once again it appeared when I was downloading the windows updates.

Has anyone else had this issue?
Is it vista/Windows 7?
Is it the Wireless card?

My Dell Laptop (Latitude 620) has a b/g card and running XP and has never had the problem.  I have had two new routers and from what I recall the problem still happened.  I have gone back to my original router (US Robotics 9106) which is a bloody reliable router.

Has anyone got any ideas as I am stumped other than faulty Wireless card.

Thanks in advance.
