USB-Wifi key driver

    Hello.


    We are looking for any USB-Wifi key and chip driver for windows CE 6.0 that is available on the market.
    We were using a USB-Wifi key to connect to a WLAN access point in our application using the RT2870 driver, but since several months this chip is not sold anymore in the market and the RT3070 is replacing it. We didn't find any driver for that and we are really stuck with this problem now as our product includes this USB-wifi driver.


    We really need help on that matter.
    Thanks for any advice.

    Hello,
    i assume that you will get driver from ralink (http://www.ralinktech.com/) without problems. In general you won't find any wce drivers on their homepage for direct downlaod but i know from other customers the they get drivers and updates on request.


    Please give us a notification of the result of your request.
    Thanking you in anticipation.

    Here are the results of all my research up to now since mid-March 2010.


    First, I tried to contact RAlink to get the drivers, but it was almost impossible to get in touch with them (no answers to emails, impossible to get through the responsible person, line hanging up, etc.. for many many calls).


    I looked on the internet about this driver for Windows CE 6.0 and there was absolutely nothing apart of the RT2807 driver that I already had.
    I got an information on several posts (including Microsoft's official answer) that the RT3070 driver was available on a particular CD shipped with a 150Mbps wifi card and that this was tohe right was to get this driver. This is the famous link everyone says the driver is available on:
    <!-- m --><a class="postlink" href="http://www.amazon.com/150mbps-Wifi-Wireless-Adapter-802-11/dp/B0030D74BM">http://www.amazon.com/150mbps-Wifi-Wire ... B0030D74BM</a><!-- m -->
    We ordered this CD (not able to ship in europe anyway), but the contents was not as advertised and they removed the winCE drivers and left only the drivers for XP, Vista, Seven and Linux. So you can forget to buy this product to get this driver.


    I also tried to contact D-Link who are selling this chip inside their DWA-140 Wifi-usb dongle (B2 hardware version uses the RT3070 instead of the RT2870 for the B1 version). No answer at all, they don't want to be asked about this question and do not provide the drivers.
    The same with Linksys (Cisco) for the WUSB600N-EU key. The FCC ID WUSB600NV1 uses also a RT2870 and the WUSB600V2 uses a RT307x chip. But the support is very poor and they don't provide at all the driver for windows CE, they even don't know what this OS is and are very rude by not providing anything at all. No way to go further with them.


    Finally, I got a pretty good contact with RALink, but they say taht they don't provide any driver for windows CE if we don't order more than 500'000 pcs/year, which is not our case at all. They invoke many reasons with engineering problems, etc.. as a reason to not provide the driver and this time I am sure that I got the right people. They don't want neither to accept an NDA to go further into this question. One technician wanted to provide me the driver but he was stopped by the marketing.. Go figure, I really think that they are hindering this driver distribution for any reason, and this makes it very difficult to get it.


    Microsoft doesn't put anything on their hardware compatibility list and they even don't seem to be aware that there is a driver done for the latest generation of the wifi n keys using the RT3070.
    Contacting many other windows CE specialists, only the latest key available was a USRobotics key but they say that it is also obsolete and that no other driver is available. It could seem that Wifi isn't supported anymore under USB for Windows CE...


    I will post more information if there is something interesting.

    Hello.


    Finally I got another company which eventually provided me the RT3070 driver.
    It is a bit confusing as it is still called RT2870, but the release date is from december 2009 so it is pretty new. Also in the driver it is written that the RT3070 is supported which was not the case with the driver dated 2007.


    Thanks for the link you provided Thomas, the driver I have is about the same packaging, except that mine is a bit newer.
    I tested my new driver with the D-Link DWA-140 Hardware version B2 wifi-usb adapter and this is working very well.
    So now at least we are able to make some usb-wifi key to work.
    Definitely, the link provided by Thomas is the easiest way to get the driver quickly, thanks for that.


    I suggest that if someone has another driver for windows CE for another chipset he would provide information on how to get it on this post, it would be helpful for everyone.


    Thanks,
    Daniel

    After some testing, here are the different USB-Wifi dongles that we have seen working well with this RT307x driver:


    - D-Link DWA-140 B1 (30€)
    - D-Link DWA-140 B2 (30€)
    - D-Link DWA-125 A1 (22€)
    - Planet WNL-U554 V4 (10€)


    The last letters are the hardware version and you must ensure that you really get this version else there is no guarantee that they didn't change the chipset in between.

    Hi,


    I have recently tried to connect a WIFI device based on the RT2870 chipset to my PicoCOM2 system, the device cannot create an NDIS instance does anyone know how to fix this??
