**So happy my [Particle Featherwing Hack](https://community.particle.io/t/mesh-hello-world/45985) works at home.** I now have a stable mesh network at school and at home. The new (version 26) Android App trys to force your Xenon with the featherwing to be a gateway and only one gateway is allowed per mesh at the moment. The hack allows a Xenon to have the stability of the Ethernet without being a gateway. My Argon has always worked at home, but the Xenons rarely were stable for more than 30 seconds. With one stable Xenon and the Argon, my home mesh network is completely stable. Note: No Xenons can as of yet help a flashing green (for more than a second) Xenon get back on the network, that Xenon must still be brought close to an Argon or other gateway. I hope a solution for this is coming soon as that makes the mesh network incredibly fragile and user intensive to restore connectivity. .. oops. . Oh, too funny.😂😂😂 The new found stability at home has little to do with my Xenon and the Featherwing. The new home stability is totally to do with the version 26 firmware that came out today. **WELL DONE PARTICLE. THE NEW VERSION 26 HAS MADE SOME HOME MESH NETWORKS MUCH BETTER.** Also at home getting much better range than at school. Less concrete and metal. Looks like about 80 to 100 meters, but because the breathing cyan is so stable, it is sometimes hard to tell when you have made 2 separate mesh networks or one network that communicates. I got 150 m from home with the Xenon stable but not talking to the Argon. That is why [my Mesh Hello World](https://community.particle.io/t/mesh-hello-world/45985) program is so useful. Hey @RWB looks like there is code to activate the Antenna. I will try some Antenna range measurements tomorrow > [@Mesh range / external antenna?](https://community.particle.io/t/mesh-range-external-antenna/45595/37): > > There will eventually be a setting to set and save the selected mesh antenna (internal vs. external). However, if you want to play around with it now, you can just copy and paste this function and call it to select the external (u.FL connector) mesh antenna. The setting is not saved. The default is internal. void selectExternalMeshAntenna() { #if (PLATFORM\_ID == PLATFORM\_ARGON) digitalWrite(ANTSW1, 1); digitalWrite(ANTSW2, 0); #elif (PLATFORM\_ID == PLATFORM\_BORON) digitalWrite(ANTSW1, 0); #… --- _[View the full topic](https://community.particle.io/t/high-school-robotics-course-using-the-particle-io-mesh-devices-blog/45692)._
