    Internet connection is strange after installing wifi usb stick


    Hello everyone,

    I wanted to create a wifi hotspot using wifi usb stick connected to my desktop.

    So I connected it, installed drivers (Rlink or RaLink, basically chinese noname) and tried to set up the hotspot. It worked, but my android phone was stuck at "Obtaining IP address". So I installed Connectify, set up Internet connection sharing from the main adapter to the wireless adapter and it worked fine.

    But since then the internet connection is wonky, for example right now I'm downloading 350MB file for the fourth time because it had always been interrupted. And the download usually stops for 10-15 seconds, then downloads really fast and stops again. I use Backblaze for backup and I can see the the average upload speed is 0.13mbit/s, before it was cca 0.35mbit/s.

    I uninstalled everything, drivers, connectify, 3 Cisco things which were installed together with Connectify (Cisco LEAP, Cisco PEAP), uninstalled the main network adapter and reinstalled it using drivers from Windows update (Realtek PCIe Family Controller). But there is no improvement :/.

    Any suggestions would be appreciated....

    Actually Ralink chips are used in a lot of name brand stuff. so that's not specifically good or bad in and of itself.

    The first thing I would suggest in an attempt to help prevent 'wonkness' would be to make sure the usb port is not set to go low power or sleep.

    To Disable Selective Suspend:

    open the control panel
    go to power options (you may have to set view to small icons)
    click change plan settings
    in the window that opens:
    click change plan settings
    click change advanced power settings, expand usb and ensure usb selective suspend is disabled.

    edit: you may also want to consider disabling ipv6 as some lower end devices don't really support it.

    Thank you for the reply.

    Right now I have the USB stick and everything that went with it uninstalled, so right now I'm dealing with a "wonkness" of the main adapter. But I checked that when it was installed and the suspend was disabled, it is also suspended in the main adapter settings.

    Should I try disabling IPv6 of the main adapter?

    Well if the problem is across multiple devices and the behavior is the same you might want to look at other possible causes.
    It seems you are using your smartphone for the wifi.
    Have you tried revers tethering?
    It allows you to share the connection directly via usb.
    and is much more stable. I believe there are two or three free apps and a ton of pay ones on android market for that.
    ...the phone will need to be rooted.
