Re: Power LED not working on Pi 3

This is quite wierd, as the power LED should come on regardless of the presence of a uSD card or OS. Does the RPi boot into a desktop? LEDs do rarely fail but I suspect it is a PC board issue. That the activity LED behaves normally, if you get to a desktop or a command prompt it would indicate that ...

Re: Pi's no longer in Windows 10 Network Dispaly

Sounds like a router configuration problem to me.

Add only the settings you absolutely need to the router config. See Netgear's instructio...

I have no help with regard to the VNC issue but once installed, the 18b20 needs to be connected during boot. I use one on my RPi based water heater controller but it is always on, 24/7.

Re: wifi not working on raspberry pi 3 model B

As you are new to Linux and the RPi, I suggest reformatting your uSD card and loading a fresh copy of Noobs from the raspberrypi.org pages. Your RPi3 should communicate with your wifi system automatically, finding the available SSIDs and asking for a key to be input if it is secured. The icon on you...

Re: No space left on device

It sounds like you might have a counterfeit SD card. Run f3write/f3read (linux) or hwtest2 (W$) on the SD card and see if it has its advertised capacity. Cheap SD or uSD cards are often counterfeit and don't have the advertised capacity. These utilities will overwrite all your files on the card, so ...

Re: Extreme slowness

It is hard to offer any help with the lack of information you provide, such as model, type of internet connection, if wifi, how far from the router or AP, etc. Without knowing any better, you are probably connected to the Pi with wifi and too far away from it. Wifi speed is directly related to signa...
