How to troubleshoot a WI-PI

Former Member

Hey folks, my WI-PI only worked for one Day, I got it up and running yesterday, and today the blue LED wo'nt even light up. Can anyone suggest a troubleshooting method?

  • Hi Daniel,

     

    First of all it's probably worth making sure that you have a dedicated power supply (i.e. not from a laptop) to make sure it can draw enough current. Which operating system are you using?

     

    What information do you have in the interfaces file? In the end I just used this and nothing else (assuming you're using WPA):

     

    allow-hotplug wlan0

     

    auto wlan0

    iface wlan0 inet dhcp

    wpa-ssid NAME

    wpa-psk PASSWORD

     

    In the more recent Raspbian distributions there is also a GUI for setting up USB Wi-Fi dongles which might help.

     

    If you don't have any luck try calling tech support and hopefully they can help you out!

     

    Cheers,

    I just bought my Wi-Pi today and I plugged it into my Raspberry Pi 2.0 and I turned it on excited to finally get internet access with my Raspberry Pi.  When I turned on my Raspberry Pi, the blue light on the Wi-Pi isn't on and the settings to set it up with my wifi won't show up.  I downloaded the NOOBSlite on my raspberry Pi and have updated everything on Raspbian to the latest version, I even deleted it and re-installed it today to see if that would work.  I really want to get it up and working as fast as I can.

    Hi Chase,

     

    What happens if you type lsusb from a command line window?

    You should see something like "Ralink Technology, Corp. RT5370 Wireless Adapter" appear if your Wi-Pi has been detected.

    If you can't see that, then try unplugging the adapter and re-inserting it (while the Pi is running), and then retry typing lsusb

     

    If you don't see the Ralink text then there may be a power supply issue; worth trying a different power supply that is rated 1A or more.

    I do see the Ralink text, what should I do now

    Hi Chase,

     

    I think the wi-pi is functioning if you can see that text. However, the WLAN settings now need to be configured. I presume you're using WPA? Could it be a password issue, or something like that?

    It could be a password issue, I can't find the settings to configure the wifi and I tried following a guide from your website that I found.  Now on the startup it says failed under the wilan0 and its sending out a ping on something. What should I do

    The easiest may be to double-check your wi-fi password by (say) trying to connect a smartphone/tablet/laptop or something to your Wi-Fi network, so that it is 100% confirmed what settings work.

    It really should be as easy as https://www.raspberrypi.org/documentation/configuration/wireless/ so if this isn't working, I suspect it is a password issue.

    (I'm assuming your router is configured for WPA2 (or WPA-PSK) and not  WEP. If you're using WEP (obsolete 10 years ago) then it needs replacing).

    Alternatively, for now just use an Ethernet cable plugged directly from the Raspberry Pi to one of the switch ports on your router, but that is merely a temporary option until you get the wi-fi password sorted, if the

    location of the router is inconvenient.
