I have an office network being run by a Linksys WRT1900AC, and I'm experiencing significant, but intermittent issues. I have between 15 and 20 devices connected to it, including computers, phones, printers, and chrome cast devices.
Upon a restart of the router, everything will work will for a short period of time, but performance will rapidly degrade over time.
Ping tests will start to reveal intermittent packet loss, both to external destinations and to internal destinations (though ping tests to the router itself, for some reason, are always fine, with zero loss). The issue some time ago, but has increased in severity of late.
Where should I start looking?
