How to enable ZRAM on Raspberry Pi

How to enable ZRAM on Raspberry Pi

Most Linux systems tend to use a little bit of storage on the hard drive as swap space, where temporary files can be stored by the system and then easily recalled later. This speeds up operations, without needing to take up any space inside of the physical memory (RAM). On a Raspberry Pi, this same convention can prove problematic due to the majority of devices relying on an SD card as the primary (or only) storage device.

Set static IP on Raspberry Pi

Set static IP on Raspberry Pi

Setting a static IP address for your Raspberry Pi will ensure that the device can always be accessible at the same IP address on your network, since it will never change. This is ideal for a Raspberry Pi being used to host a service such as a gaming server, web server, etc. It makes it more convenient when applying network configurations, since you know that the Raspberry Pi can always be found at the same, predictable IP address.

How to check WiFi signal strength on Raspberry Pi

How to check WiFi signal strength on Raspberry Pi

The latest Raspberry Pi models have WiFi chips built in that allow the device to connect to a wireless network. If you are connected to WiFi on your Raspberry Pi, but experiencing poor speed or dropped connections, it is time to check the WiFi signal strength to begin troubleshooting the issue. Generally, the little WiFi chip built into Raspberry Pi 4, Raspberry Pi 3, or Raspberry Pi Zero W models is about as strong as the one you would find in your mobile phone, but checking the signal strength will tell you if you are close enough to the router or hotspot.
