The symptoms: Without the card when plugin the power, the green LED blinks with a repeating four blink pattern (this is Ok I think)., with the card I get a red ...

After installed a fresh, newly downloaded copy of Raspbian I am getting "no wireless interfaces found". ... What "waveband" does your WiFi (router) use - 2.4GHz or 5GH...

Re: Black Screen of Death

Previous response is all irrelevant. I should add that I've seen many similar references to this problem on the forum, so the problem is by no means unique to me. It's not a problem at my end. I just hope the developers can fix it - although, to be fair, it is merely an annoyance, not a show stoppe...

Re: Raspbian Buster from desktop back to headless?

Another approach might be to: a) Uninstall some of the recommended software (that will free up space). This is probably easier with using the Add/Remove software GUI from the Preferences menu. then b) change the boot option to be to the Command Line rather than the Desktop (gives you the option to u...

What can I do to get the Pi4 working headless properly.? Are you trying to access the console desktop via VNC? If so, as I understand it you'll need to tweak config.txt on the 4B to "convince" it that a monitor is connected. If no monitor is detected at boot no frame buffer is created so there's no...

Re: Raspberry Pi 4 B will not connect to 2.4Ghz wifi

Perhaps this is the source of my problems as well. Just got an RPI4 and getting horrendously slow throughput on Wifi, unusable for web browsing. Possibly because the 5Ghz band has less range, and it won’t connect to the 2.4 Ghz band. Would be very interested as to why this is the case. Are you (all...
