I've setup/installed an RUT240 as a replacement to satellite internet for a family friend. So far it has been flawless with the exception of Netflix which completely stops working on all devices on the LAN. All the other streaming services and general internet browsing works fine when the problem is occuring. Rebooting the RUT240 fixes the issue temporarily but re-occurs generally within a few hours. It's quite literally only Netflix and occurs on all devices connected to the network. I had discovered people ran into issues when DNS rebind protection was active and so I disabled it, but the problem returned the following day.
I've updated firmware, tried static IPs and DNS settings. I'm getting kind of desperate so any help is much appreciated.
EDIT* Just in case anyone comes across this in the future I wanted to provide a final update. In the end it was the operator, specifically Optus in Australia. I tested a Telstra sim and the router worked perfectly for 3 days straight (including netflix). I've also noticed the connection is considerably more stable as well. I spent hours trying to get the Optus sim to work, but in the end it wasn't worth anymore of my time.
