DW1501 Wireless-N Wlan Half-Mini Card

This question is not answered

Cant' seem to find any updated drivers for this card.  Just installed new AP's supporting wireless 'n', and can't seem to get the speeds past 54MBS.  AP's are configured properly.  Under the setting in device manager I can see the rate setting for 802.11(b/g), but not n.  If this card is not 'n' compatiable why state that it is.  Hoping to get an updated driver .  My version is 1/7/2011.

  • 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 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,

  • 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.

  • The spec sheet isn't what we are after here.

    We need a solution to the problem!

    I have a Dell Precision with this card and can't get over 30MB/s. This is not acceptable.

  • I have a Dell XPS 8300 that contains a DW1501 Wireless-N Half-Mini card. My wife & I recently moved to a location where my computer is farther from the router than it used to be. In our previous home, even when the XPS 8300 was directly adjacent to the router, even touching, the best reception displayed was 4 bars and now it is 1-2 bars. After reading the posts on various forums, I decided to replace the DW1501.

    I bought a TP-Link TL-WN822N, which is a high gain USB wi-fi antenna system.  The signal strength was immediately healed; it now shows 5 bars versus the former 1-2 bars in our new home. I have Cox internet and when I run Speedtest, it shows anywhere from 15-40 M bits down and 6-15 M bits up.

    The speed is fine but occasionally it misses packets for anywhere from 2 seconds to several minutes. In these situations, the link to the router is usually strong but is loses the internet. The customer support line at TP-Link said the problem was the system sometimes confuses adapters and sends the data to the DW1501 even when the USB based wi-fi is the one which is selected.

    I've disabled the DW1501 and uninstalled the drivers. Also, I've unplugged the black and white wires that connect the DW1501 to the power supply. The frequency of these errors is now low but is extant. I think(hope) the remaining problems will be solved if I actually removed the DW1501 from the motherboard. Also, whenever I reboot, the DW1501 drivers automatically re-install. 

    Does anyone know how to remove the DW1501 from the motherboard?



  • Its quite easy to remove, have a look at the Service Manual:
