This page describes how to configure the network interfaces for a Raspbery Pi running as a Wi-Fi Access Point (AP). This is just one step in a larger list of instructions, which can be found on the page Raspberry Pi Wifi Access Point. The instructions here do not include the routing, which is covered later. […]
What a difference a year makes. Last year I made a time-lapse video of the Vernal equinox in Wooster Hall by standing next to a wall and taking a photo about once a minute for an hour. This year I have a much nicer video from a raspberry pi camera which captures an image every […]
I have an old iPad which has been dropped so many times that a piece of wire fell out the side, and I think that wire was the WiFi antenna. The iPad can only connect to WiFi when it’s close to the access point or when the signal is very strong. I figured out that […]
This is the last step required to turn a Raspberry Pi into a WiFi Access Point. If you want to see all the previous steps, start with “Raspberry Pi Wifi Access Point“. When you get to this page you should already have done the following: Configured both network interfaces, Set up hostapd (a daemon which lets […]
DHCP stands for “Dynamic Host Configuration Protocol”. The DHCP daemon is the process which assigns IP addresses to computers when they join a network, and gives them other important information about the network, including DNS server addresses. A local network used for a wireless Access Point usually has a DHCP server associated with it. […]
The daemon hostapd is a Linux service which enables a “host” computer to become a WiFi Access Point (AP). Thus “host” + “AP” + “d” (for daemon) gives the name hostapd. I originally learned to set up hostapd from instructions on Pastebin written by user Dryfire117,1 andlater found useful instructions on the Raspberry Pi […]
Whenever I flash a new SD card with a Raspbian image, there are a number of configuration steps that are needed to tune the configuration. This post is just to record the steps for my own future reference. It’s based on the latest (as of this writing) release, which is Raspbian Stretch. Edit the […]
