Wrong driver my friend.  No compatiable hardware found.  Had to re-install original driver.  Does this adapter support wireless 'n' conectivity as the description says?

Midnight251,

The Dell Wireless 1501 Wireless-N WLAN Half-Mini Card adapter works on 2.4GHz ONLY. It uses dual streaming to get the faster speeds.

Please continue with DELL-Nikhil D and see if he can get your adapter to get the dual streams.

I have purchased 5 Latitude E5520's over the last year for our company, and all these have the 1501 card in them, and apparently will top out at 74MBS.  Our access points work in the 2.4 GHz range only. They are Trendnet TEW-653AP's.  Found this post:

It looks as though Dell has had some issues with these cards.  I would like all of these cards replaced by Dell.  It looks as though a lot of people have been getting the run around. 

Just came across a Vostro 3300 I purchased for the company about a year and a half ago which has the same card. Getting a whopping 52Mbps on a 'n' network...........

Rick, thanks for the info.  Nikhil, any info on this?

Real easy question folks.  Can this card connect at N speeds?  

Hi Midnight251,

Specifications of 1501 wireless-n card.

Hope this helps.

How is it 802.11n if it doesn't support 40 MHz channels at 5.2 GHz?  I thought the whole reason for these 802.11 standards were to ratify STANDARDS.  I think the IEEE should force manufacturers to support 40 MHz in the 5 GHz band for 300 Mbps in order to receive 802.11n certification.  Otherwise if your only running in 2.4 GHz, why not just call it 802.11g then.  And likewise if you're running in 5.2 GHz, but don't support 40 MHz channels, call it 802.11a.

All of these hidden sub-specs of 802.11n defeat the purpose (and lower the value) of the term Wireless-N.

Kjstech, your right on.  We had purchased some E5520's and according to the specs they supported 80211.n.  Imagine our supprise when we upgraded to 802.11n and the laptops would not support it.  Let's just say our company has not purchased another Dell product.
