Reporting here: since installing FW 8.1.0 (update from FW 8.0.2) , browser speed tests cause my Soho Mark III to crash during the upload speed part of the test.
This happens every single time I run a speed test (I’ve done about 15 this morning).
I have Google Fiber that ordinarily has equal download and upload speeds. The problem is that a higher (for U.S. residential) upload speed (anything > 55 Mbps) sustained only for 5-10 seconds causes the Mk 3 to crash every time.
I have no way of rate limiting my own upload speeds and this is causing me serious issues with my ability to telework.
I have not enabled any of the new features in this update.
