    Set the router clock with a GPS receiver for under $70

    And it's important to note the major difference, that a microcontroller is an entire computer on a chip, while the 8086 is only the CPU piece.

    Set the router clock with a GPS receiver for under $70

    The "Nano" is an ATmega328P 16 MHz 8-bit microcontroller. There is no operating system. The program has one main loop. This unit is about the size of my little "pinky" finger, from the knuckle to the tip. See all the Arduino models here: https://www.arduino.cc/en/Main/Products I briefly...

    How to access modem at 192.168.100.1

    Change the Subnet Mask to 255.255.0.0. Now he can see me from from 192.168.0.0/16.

    Set the router clock with a GPS receiver for under $70

    My latest update is to use Arduino Nano with a real-time clock. So I follow this project with some tweaks. Soon, it all goes into a little black box. In some parts of the world, they arrest you for bringing it to class. Specifically, I have these pieces here: Arduino Nano (CH341 UART)...

    Updated How-To? TM-AC1900 (T-Mobile Cell Spot) to Merlin Firmware Guide?

    I think it is possible to re-flash the CFE with JTAG of the RT-AC68U. Or, it is possible to use pogo pins with point tips to reprogram the flash directly without desoldering it from the board.

    N66U Mystery Reboot after 50+ days?

    Possible causes and solutions: 1. Drawing too much power through the router's USB port. Try using an external AC to 5V DC USB power adapter for any USB-powered devices. 2. Overclocked CPU might be causing system instability. Reduce the CPU clock speed if you are overclocking the CPU. When...

    How to set a Random WAN Mac at each boot?

    This sample code will put a random MAC address in a variable, for an Asuswrt-Merlin router. However, I don't know what the next step is? AUTOMAC=$(m=$(/usr/sbin/openssl rand -hex 6|/usr/bin/tr [a-z] [A-Z]) && /bin/echo ${m:0:2}:${m:2:2}:${m:4:2}:${m:6:2}:${m:8:2}:${m:10:2}) echo $AUTOMAC Next...

    Exercising a new router for remote deployment

    Know the ambient room temperature where the unit will be deployed because a busy router without any additional cooling will get 60C degrees hotter than the ambient room temperature.

    OpenVPN with static key for all local network clients

    Is it broke? This post will show you how to customize the VPN routing script. Just in case you want to try. http://www.snbforums.com/threads/openvpn-policy-routing-guide.24384/page-3#post-199658

    How to disable Windows 10 tracking using ipset + Entware

    Yours is an ARM router, so you must change "--set" to "--match-set" in the script. Here's an auto-detect logic to pick the correct one. I have not tested it. # Apply iptables rule if [ $(/usr/sbin/iptables-save | /bin/grep -q Win10tracking > /dev/null 2>&1) -ne 0 ]; then if [...

    Entware-ng for arm, mipsel ....

    Thank you. I compiled my little C program and it runs fine. If I needed to build a statically linked version of some program on the router, is this possible? I've cross-compiled Entware-ng on my laptop and it appears to have built all the static libraries (the ".a" files). Can these be used...

    Entware-ng for arm, mipsel ....

    Is it possible to compile a simple C program without the Entware-ng dependency? gcc hello.c -o hello #include <stdio.h> int main(int argc, char **argv) { printf("¡Hola USA!\n\n"); return 0; }

    Overclocking on Asuswrt-Merlin 378.56_2 (RT-AC68U and RT-N66U)

    I cannot answer about the RT-AC66U. However I see this, https://github.com/RMerl/asuswrt-merlin/blob/1431f2518b2f8c2e1f241e86cc5cf4f38f5eaab2/release/src-rt-6.x/cfe/build/broadcom/bcm947xx/compressed/rt-ac66u_nvram.txt

    Force LAN port 4 to use the Guest network for Asus/merlin RT-AC68U

    Now I see how ASUS uses ebtables to set up the Guest Wi-Fi networks. The ebtables filter table seems to be where the device isolation happens. 2.4 GHz Guest Wi-Fi is on interface wl0.1. 5.0 GHz Guest Wi-Fi is on interface wl1.1. ebtables -t filter -L --Lmac2 --Lc --Ln -i wl0.1 -j DROP -o...

    Force LAN port 4 to use the Guest network for Asus/merlin RT-AC68U

    I need to learn more about this. It seems that the Guest Wi-Fi 2.4GHz and 5.0GHz networks (wl0.1 and wl1.1) both use this same brouting technique to make a Guest Ethernet network. A Guest network means that the computers cannot see each other. ebtables -t broute -L --Lmac2 --Lc --Ln

    Wireless and VLANS

    Here's my guess for RT-AC68U router. If you have a different router, it may number the ports differently. In this sample code, the RT-AC68U router will expect VLAN tagged data from the switch. So if nothing else works for you, give this try. /jffs/scripts/firewall-start robocfg show | grep...

    Overclocking on Asuswrt-Merlin 378.56_2 (RT-AC68U and RT-N66U)

    Yes, I care about my laptop temperatures too. When compiling Asuswrt-Merlin I must sit my laptop on a box with dual 120mm 5V DC fans inside, directing air upward toward the laptop. If I don't do this, the GPU fails due to the high temps, causing the screen to go black. For larger builds, like...
