I’m quite familiar with openwrt and gl’s line. I have been using them for years in all kinds of edge cases where flexibility is needed. I’m certain a VPN is needed.
The system I’m designing is not for technical network administrators, it is for employees who’s job it is to install and configure solar systems. They just need it to work and wouldn’t know what a ssh was if it was taking a nap on their lap. I have already mapped it out and validated the configurations.
I’m curious does the ar300m ext model actually give more range with the external antennas? There will never be much load/connections on these. But in some cases stronger 2.4ghz will be necessary. I think we can use a mix of devices. Possibly the n300 for sites with good signal and the ar300m ext for more complicated sites.
Any plans for a new usb router stick? That would be ideal in some cases.
