If you could - please do answer vogon’s question as well, as the information would be valuable.
Usually, you would leave the values as they are, but you can try changing the MTU to 1420(increments of 20), for example, not recommended to go lower than 1280, as it may break connections even more.
No, but IPv6 isn’t widely supported yet - I would recommend forcing the PDP type on your mob1s1a1 interface (I presume you use mobile) to use IPv4. To do that, you would head to Network → WAN → “Edit” on the mob1s1a1 interface → PDP Type: IPv4 → Save & Apply
By default, there are 2 interfaces for the WAN, specifically, which are WAN and WAN6; one is responsible for IPv4, the other for IPv6 - you can disable the WAN6 interface.
Could you please confirm what firmware version is in use currently? This can be seen in the top right corner of the WebUI, or under Status → System - if you don’t have the latest, please upgrade. Next, please clarify - how often does this happen exactly? More specifically, does it happen, say, every 2 hours, or happens completely randomly? Do you have any kind of firewall/traffic rule-related changes made on the device? What power supply are you using with your RUTC50?
We can move to a different channel, of course. I’ve sent you the form, which you’ll receive in your email inbox. Simply fill it out with your contact details, and in the TICKET ID field, fill out 17452, which is your Thread ID.
How are you able to see the drop rate? I’m not using the Wi-Fi interfaces on the router itself, but the router is connecting to repeaters (DECO) inside the house. Router is set as NAT and repeater on AP mode.
Once the form is filled out, a ticket gets created in a separate system. Afterwards, we need to reply to the said ticket for you to receive an e-mail, to which you can then reply. If you haven’t gotten anything, means I haven’t replied yet.
