Dell Wireless 1505 Draft 802.11n WLAN Mini-Card Can't get draft-n speed out of it.
I recently upgraded my Inspiron 1525 with a Dell Wireless 1505 Draft 802.11n WLAN Mini-Card from Windows Vista 32-bit to Windows 7 64-bit and while the wireless connects, it is only at 54 mbps. I check on my Dlink DIR-655 and under the wireless clients. It says that it is connected 802.11g. When I was still on Windows Vista 32-bit, I was able to connect at over 100mbps most times.
I am sitting next to the wireless router 5 feet from the thing, and I can still only get g speeds.
I assume that this is due to the driver, which is the Broadcom 5.30.21.0 driver from 10/1/2008.
Is there another driver that I can use to re-enable wireless n speed?

I have the exact same issue. I'm on a Inspiron 1525 with Windows 7 x64, using driver: 10/1/2008 4.1766.75.21
I just bought the 1505 card to get 802.11 N on my laptop.
I've tried to change some of the Advanced properties, but nothing results in N speed . I'm connecting to an Asus RT-N16. I've tried the latest firmware, and even flashed it to DD-WRT, none helped with the connection speed.
Can we get info on an offical Dell Win 7 driver for the 1505 802.11 N WLAN mini-Card?

I'm getting N speeds now, after switching the two speed properties for b and g speeds to "Auto" ( they were on 54 ). Why this affects N, I don't know. but i'm bouncing now between 168Mbs and as high as 250Mbs.
I'm using the greenlight preamble, and i have the 40MHz intolerable disabled.

Thanks for the update McMalakai. I have the greenlight selected and 40MHz intolerable disabled, but don't have an "Auto" option for the b and g speed, just "Best Rate" and the settings are called Rate (802.11a) and Rate (802.11b/g). Should I be looking for this speed setting somewhere else?
What are all your settings on the "Advanced" tab of the Dell Wireless 1505 Draft 802.11n WLAN Mini-Card Properties window.
My driver has the same date, 10/1/2008, but the version is 5.30.21.0. If you have another driver, where did you get it? Is it the original 32 bit driver?
I appreciate your help.

Uninstall that driver. That driver came as an optional Windows Update drive for all broadcom cards with that chipset. Unfortunately, I never get above 54Mbs with that driver. The Original driver that comes with Windows 7 works, and has 'auto' in the dropdown instead of 'best rate'.
I've updated to that driver twice and it always kills my N speeds. I don't have the original driver's version number right now, as i'm not on that machine. But somewhere else in these board is where I heard the trick about using the original driver only.
Still even the original driver gives me 'flaky' N speeds. It seems to be trying to increase the linkspeed on demand, and that can cause latency jitters in many bandwidth heavy apps.

Worked like a charm, driver 4.176.75.21
I'm still only getting up to 117MBs, but that's still better than double. Weird though, it still has "Best Rate" for the a and b/g speeds. Whatever, It's still better, and I can now think about transferring files across the network, and have a better remote desktop connection to the other computer on the network.
Thanks again!

I am having a problem with my card I believe that is somewhat similar to you. I can connect at 270 mbps but when I go to transfer files I am only utilizing 8-15% of the network topping out at 40-50 mbps. My driver is 5.10.38.26 dated 10.22.2008...where do you go to get different drivers. I am on WIndows 7 32bit. Thanks in advanced.

Hi Jayjasu,
Sorry, but I'm not sure that I can help with that problem. When I uninstalled the updated driver, (can't remember the driver number, because I don't have that laptop any longer), and reinstalled with the original Windows driver, it connected better.
Usage of bandwidth, however, that's way beyond me.
