Re: Raspberry Pi Over voltage

Which model Pi do you have?

Wait 24 or more hours and then then try to reboot. This should allow the polyfuse time to reset.

Re: RaspPi 4 WiFi Range?

Wifi is a radio transmission and is effected by the usual objects. I have seen Wifi being blocked by temporary walls in an office building since metal 2x4s were used. The issue was resolved by adding range extenders or additional access points.

Re: Pi power input (solder points? I)

All grounds are the same ground, just a copy closer to power or other specific pins. For many versions of the Pi you are avoiding the polyfuse and run the risk of damage from over current faults. Note the polyfuse can reset after tripping with time unless really damaged. Use this approach at your ow...

Re: RPi4 wake up after power failure

The power button most likely prevents the restart after a power failure. Some consider this a benefit since the device is powered off during the period of many power spikes when power is restored and the many heavy draw devices power up causing power surges.

Unless you are a root user, you must use the "sudo" command to install that package or any package.

"apt-get" is the command to update and upgrade raspbian, so I find it hard to believe it does not work.
