i just got a wifi pineapple mk7 yesterday and when i first got it it worked fine but today i tried to connect to it using the usb ethernet and it says cable not connected. sometimes i can connect to it for a few seconds and then it stops working again but most of the time it just doesn't work at all i dont know how to fix this the led on top acts as normal it blinks blue for a few seconds when i first plug it in and then it goes to solid blue
