strange problem with wireless N on dlink dir-615 / toshiba laptop

Should encription like wep / wpa etc be any different if your laptop
is connected in Wireless N mode v's G or B etc.
Here's whats bugging me at the moment. I have a new toshiba laptop
with wireless N capabilities and a dlink DIR-615 router. The DIR-615
has a setting which can force "wireless N only" mode which i turned on
just to test out the wireless N speeds etc. With encription turned off
it connects ok (speed was 150mbs ..5m across the room). The minute i
turn wep or wpa or wpa2 on my laptop wont connect (yeh im putting in
the same passcode into the laptop etc!). Yet if if change the router
to accept all speeds (ie wireless N G B etc), it connects ok wiht
WEP/WPA etc but only connects at 54mbit G settings ..not N. Basically
if i use any encription ie wpa/wep etc it wont connect with wireless
N settings?


Any ideas?

Meanwhile, at the alt.internet.wireless Job Justification Hearings, bitz
chose the tried and tested strategy of:

Update firmware on the router and make sure you've got the latest wireless
drivers. Try either a different router or a different client PC/wireless
adapter to prove it off.

Hi,
I had similar issue with Belkin N+router. It is a design fault of WiFi
radio chip in the router. Maybe your D-link router uses same chip.

wow - thanks for posting -
will have to remember that for future....
does the actual "N" spec now allow for these encryptions ?
