    USB-LAN adapter not recognised


    The following notebook/laptop does not have a LAN port:

    Lenovo 100S-14IBR

    Hence I have purchased a USB-LAN adapter as I do not have wifi where I live.

    The adapter I am using is:

    Sitecom USB LN-030 v3 001

    The adapter is not being recognised by the laptop.

    If you have any suggestions as to how I can resolve this matter, I would be grateful for your help.

    What I have done thus far:

    (1) I have reinstalled Windows 10.

    (2) I have installed the relevant drivers from the Lenovo website.

    (3) According to the Sitecom website as well as the seller from whom I purchased the mentioned adapter, no drivers from Sitecom are required in regard to Windows 10.

    Where do I go from here?

    Thanks in advance,

    To get the built in driver activated, you may need to run windows update.

    Can you take the laptop to a public WiFi area, connect to adapter and search for a driver online?

    I like to use something like this: TP-LINK TL-WR702N Wireless N150 Travel Router, Nano Size, Router/AP/Client/Bridge/Repeater Modes, Up to 150Mbps, USB Powered: Computers Accessories

    Advantages - use a cheap USB wall charger for power and your computer needs no extra hardware or network cable so you can move your computer around mostly as you please. Also makes WiFi available from your wired network for your other devices like a cell phone.

    When you travel, you can take it with you and power it from computer USB port.

    Hi there

    Usually the really cheap USB-->Lan adpters just work - the cheaper self powered ones are better than the more expensive ones. Ensure the Ethernet cable is connected to AN ACTIVE NETWORK as if the network isn't active the signal might not be be recognized so the computer won't detect your hardware. In general connect to a USB 2 port if you have one.

    Windows (most releases from about Windows 95 onwards) have some sort of built in generic ethernet driver built in -- this will be enough to connect to the Internet if you need a better driver. LAN protocol has been around ever since "Pontius was a Pilot (Pilate)" so complex drivers are unnecessary.

    Usually also there's a light which often will be Green if it detects a 1Gb/s LAN or yellow / Orange if it drops to 100 Mb/s but that will depend on the hardware.

    Believe me the real cheap and nasty plasticy ones work much better than the smooth metal colured expensive ones !!!! In fact the more obscure the make the more likely it is to work !!!!.

    Another solution is to buy a cheap Wifi extender -- you don't need a new router -- plug the extender into your LAN connector and now you can use your OWN Wifi !!!!. I think this would be the best solution as you can then use the Wifi from the extender to connect other devices such as smart phones / tablets etc or even another computer or two.

    NavyLCDR's suggestion is also quite good although you'd get much better transfer speeds using a dedicated extender espcially if you can use 5GHZ Band for wifi --probably cheaper too.

    Please verify the model ln-030 v3 001 - I couldn't find v3 on
    The ln-030 has a few HW revisions - please post a screen shot of the label

    There are older drivers for the v1 HW, but no drivers for the v2 HW

    Arc's suggestion to use Windows Update and Jimbo's suggestions to connect a cable to your USB LAN adapter and to your network + use a USB 2.0 port are good places to start.
