To build a routed wifi network using Raspberry Pi we will use hostapd and dnsmasq software. In this example, our home network is 18.104.22.168/24 and the new network we will use for wifi is 22.214.171.124/24. Please note that throughput on the Raspberry Pi wifi interface is limited and you should not expect speeds higher than 25-30Mbps.
To start the installation, download the Raspberry Pi Imager from the official Raspberry Pi website. Insert the SD card (min. 8GB) and select Ubuntu Server 20.04 LTS from the list of the available operating systems. Once the write and verify is complete, insert the SD card in the raspberry pi, connect the HDMI, network cable, and power source.
After you have connected DS3231 to your Raspberry Pi, edit the /boot/config.txt file and add the following lines:

When you attach custom ISO in your Update Manager, and scan host for upgrades, you will be presented with the result “Incompatible” and in the error detail, there will be message: Continue reading “Upgrading to VMware ESXi 5.5 Update 1 fails due to conflicting VIBs”
