Dell Wireless 1505 Draft 802.11n WLAN Mini-Card faster using G than N
I have two laptops (7 month old Inspiron 1520 and 5 month old Inspiron 1525 - both Vista Home Premium and up to date with Windows Update) with the Dell Wireless 1505 Draft 802.11n WLAN Mini-Card.
I purchased a Linksys WRT160N router. I have a 6 year old dell desktop direct connected to it and the laptops connect wireless with WPA2 Personal and AES
Here is the problem I am having with the wireless.
When connected with my old WRT54G router or the new one set to "G only" the network status shows about 36-48 Mbps. When I go to CNET Bandwidth Meter (http://reviews.cnet.com/7004-7254_7-0.html) it shows about 600 Kbps.
Now, when I set the new router to Mixed (g & n) or N Only the network status shows about ~75 Mbps. However, when I go to CNET Bandwidth Meter (http://reviews.cnet.com/7004-7254_7-0.html) it only shows about 200 Kbps. Copying a file from my desktop seems faster, but browsing the internet and downloading files is noticably slower.
I found that if I change to WPA with TKIP, the speeds picked up. But I want to use WPA2/AES.
I have also tried the same with a Netgear Dual Band WNDR3300 with the same results.
So 2 laptops with 2 different routers have had the same issue.
It doesn't make sense to me that browsing with wireless N is slower...
Is there anything I can do to get the Dell Wireless 1505 Draft 802.11n WLAN Mini-Card to run faster with WPA2 Personal and AES and wireless N?
Is this working for others??

We can assume you have the most updated drivers? Wireless speeds and trying to document them are witchcraft at best, especially with N. Unless you have the most current drivers, zero inteference, and the latest equipment, anything can vary.
You rely upon a web based utility to compare two products whihc is a little faulty becasue you have no control over the traffic in and out of that server.

I burned another 3 hours and did some more tests last night.
Here is my wireless card in my Inspiron 1520:
- Dell Wireless 1505 Draft 802.11n WLAN Mini-Card
- Driver Provider: Broadcom
- Driver Date: 10/12/2007
- Driver Version: 4.170.25.17
Note: I moved the laptop closer to the router (~15').
Inspiron 1520 - N Only w/No Security
- Speed: 78 Mbps
- CNET Bandwidth Meter: ~250 Kbps
Inspiron 1520 - N Only w/AES Security
- Speed: 117 Mbps
- CNET Bandwidth Meter: ~250
Inspiron 1520 - G Only w/AES Security
- Speed: 54 Mbps
- CNET Bandwidth Meter: ~590 Kbps
Dimension 4300 Desktop - Direct Connect
- CNET Bandwidth Meter: ~660 Kbps
The Dell Wireless WLAN Card Utility shows the router as b,g,n with a speed of 270.
If I go to the dell1505 card configuration and set "Disable Bands" to "Disable 802.11g/b", then the card cannot find the network at all. As though N isn't working for the 1505 card.
I tried this on my son's XPS M1530 which has the same 1505 card and driver version and my wife's Inpiron 1525 which has the same card but older driver and pretty much got the same results.

The only thing I can add is to say is that is does not make sense that your connection is slower with no security.
I think you are now seeing the reason that N is not widely accepted especially with third party cards. Sorry I can be of no help.

oops, that was a typo.
The speed for no security was the same as with security.
