In this episode, I show you how to take a Raspberry Pi, and make it a great custom home router, better than what you can buy. A Raspberry Pi 4 comes with plenty of improvements over a stock router, like a better ARM CPU, more RAM, increased storage and two 2.0 and 3.0 USB ports. There are drawbacks with using a Raspberry Pi as a router, as it only has 1 Gb ethernet port, and smaller WiFi chip / no WiFi antennas, reducing potential WiFi coverage. However, these drawbacks are overcome with a network switch and access points. Another way to overcome them is by using different single board computers (SBCs), such as a Raspberry Pi CM4, Banana Pi BPI-R2, ClearFog Pro, Seeed Odyssey, and many other SBCs. With OpenWrt https://www.youtube.com/watch?v=fOYmHPmvSVg openwrt with vlans. https://www.youtube.com/watch?v=csI19aOJEik and https://www.youtube.com/watch?v=TdUxWEyafUg wifi 6 1.5gigs by Jeff geerling https://www.youtube.com/watch?v=w7teLVwi408 Take a look at the two smallest Raspberry Pi Routers in existence: The DFRobot IoT Router Board Mini and the Seeed Studio Routerboard! Along the way, learn about networking, OpenWRT, and how these two routerboards stack up against each other. I believe you can get really good value switches or routers but, having a RPI like this to play with OpenWRT is heaven on earth Low power consumption, ability to use part of the router in other projects (I'm talking about the CM4 board) and the software supports that will keep on growing over time is very nice! Also, did you have a look at Banana PI R2? https://www.youtube.com/watch?v=km81ph7pZz8 by Networkchuck refs https://github.com/RoganDawes/P4wnP1 P4wnP1 is a highly customizable USB attack platform, based on a low cost Raspberry Pi Zero or Raspberry Pi Zero W. https://www.youtube.com/watch?v=jlHWnKVpygw In this video, I built something I actually used on my family road trip….a Raspberry Pi ROUTER!!!! It is the perfect VPN travel router and it kept me and my family secure while we were on the road. In this video, I walk you through every step to build your very own Raspberry Pi Travel VPN router using NordVPN esp32

https://github.com/open-mesh-mirror/batman-adv and https://www.open-mesh.org/projects/open-mesh/wiki, https://www.open-mesh.org/projects/batman-adv/wiki Batman advanced is a new approach to wireless networking which does no longer operate on the IP basis. Unlike the batman daemon, which exchanges information using UDP packets and sets routing tables, batman-advanced operates on ISO/OSI Layer 2 only and uses and routes (or better: bridges) Ethernet Frames. It emulates a virtual network switch of all nodes participating. Therefore all nodes appear to be link local, thus all higher operating protocols won't be affected by any changes within the network. You can run almost any protocol above batman advanced, prominent examples are: IPv4, IPv6, DHCP, IPX.

Batman advanced was implemented as a Linux kernel driver to reduce the overhead to a minimum. It does not depend on any (other) network driver, and can be used on wifi as well as ethernet lan, vpn, etc ... (anything with ethernet-style layer 2).

In this video, I explain what this standard can be used for, the different chipsets available and full products that use it. Thanks for the comments, everyone! I'm really surprised at the amount of attention this video has got and it's keeping me motivated while I work on other video projects. I wanted to answer a common question: The 900MHz band (906-928 MHz) is unlicensed (Usable by the general public) in North America, South America, and some other places. From what I can tell, Australia can use 915-928 MHz. If you live elsewhere, like the EU, you will want to check your country's specific regulations and rules before using 900MHz equipment as it could be possible to cause interference with cellular networks or public safety radio systems. In the EU, 863-870 MHz is available with a 1% duty cycle limitation and some TXW8301 modules are able to make use of that band, although I'm not sure if the chipset does anything to self-police the duty cycle limit. https://github.com/PirateBox-Dev
