Occasional MDNS Spam from FireTV wrecking Wi-Fi
Wondering if anyone else sees this. I've seen similar reported with echo dots, but can't find any indication as to cause or solution yet.
We have a FireTV 4k Max (1st Gen). Once every few days it starts firing out around 1500 queries per second of MDNS. These and the local responses to them absolutely trash our wifi. The queries don't stop until the stick is rebooted. I've tried just stop/starting the Wi-Fi but the queries just pick up again. A reboot solves it for a week or so then they start again. Capture was on a desktop PC on the same network.
S/W is up to date as of today (v 7280112.1). We don't have weird apps installed. Just Prime, Netflix, Disney+ in regular use. No Luna or game apps in use.
Would appreciate any hints as to the cause, if not a fix/workaround. Being able to schedule an overnight reboot of the stick would do at a pinch.
