Since I bought that router I'm experiencing disconnects from internet every 5-10 min. I tried to research this problem but to no avail. Everything is fine if I connect my old D-Link DIR-615.

FW version: I tried last stock and last Merlin .40 and .39 (current)
HW acceleration: OFF

This is debug log of what happens:

So, rcvd [LCP TermReq id=0x5f] means termination request sent from my provider? Or that router tells provider that it will now disconnect? What exactly is 0x5f? Why is it happening out of blue?

Go in to WAN settings, and change the last option from Aggressive to Normal.

This has been discussed dozens of times on this forum.

Switched off router for the night and then it worked without disconnects for 440 minutes. But after that again...
