the board in okay but i'd rather have a smaller metal enclosure so how does it work as a network router though both boards are perfect for openwrt so my next step was installing it i'll start with dfrobotsport right now openwrt doesn't have a full version that works out of the box with the compute module NUMBER_TOKEN so until that happens dfrobot offers a custom image based on the latest development snapshot and there's a link to it on the router board's wiki i downloaded that image to my mac and decompress the image file then i inserted the microsd card i was going to boot the pi from and wrote the image using dd with the command you see on the screen i popped the micro sd card into the router board and plugged in the pi to boot it and well this is a little weird if you're used to using a monitor with your pi this board doesn't have a display output so there are only two ways you can get openwrt setup first you could use a serial console through usb on another computer or second you could plug the ethNUMBER_TOKEN port directly into a computer and access the openwrt web interface at NUMBER_TOKENNUMBER_TOKENNUMBER_TOKEN i wanted to access the web interface but which port is ethNUMBER_TOKEN it's not labeled on the board itself but at least it's in the documentation i wish the ports were labeled on the board though it would save me having to look it up whenever i plug in the board anyways i plugged the router board straight into my mac using a separate network dongle and went to the router's address in safari the default login is root with no password and i was in the first thing you should do is set a root password once that's done you can also log into the router via ssh in terminal or using putty if you're on windows the login is root at NUMBER_TOKENNUMBER_TOKENNUMBER_TOKEN the usb NUMBER_TOKEN type c port on the side is actually disabled by default but that's not the fault of the router board that's a limitation of the pi you have to manually go in and add this configuration line in the URL_TOKEN file and reboot if you want to use that usb port openwrt also doesn't expand your boot volume to use all the available space on the pi's storage so if you want to have all that room available you have to adjust the open wrt route partition manually with all that setup work done it was time to start digging into the system first i plugged in my internet connection in my case for this test the rest of my homeland into the ethNUMBER_TOKEN port on the right and i installed pci utils so i could check out the ethernet chip with lspci and there it is with the rNUMBER_TOKEN driver loaded for the realtek gigabit ethernet controller now let's do some tests to see how well it runs first the most basic test i unplugged my NUMBER_TOKEN gigabit wired connection from my mac and turned off wi-fi so all my network and internet connections would go through the router board i ran a few speed tests on URL_TOKEN and my cable gigapower connection actually lived up to its name giving me around NUMBER_TOKEN megabits of bandwidth that's the same result i get over my normal home gigabit network so there's no
NO_SEGMENT_TOKEN
