The next situation surfaced final week and I’m not certain anymore if this occurred earlier than or after I upgraded to Monterey.
I’m utilizing a VPN connection for work however since final week this connection solely lasts for 60 to 90 seconds. Within the first 60 seconds all the things is working. The machine is linked and has web. After these 60 seconds the web connection stops working and round 30 seconds later the VPN shopper tells me that the VPN connection has been terminated.
Now, after some attempting round it was advised to me to attempt to entry the web from one other connection so I switched from my house router to a cell scorching spot.
And there you go. With the cell scorching spot all the things is working fantastic for hours.
Clearly, this makes the router the primary suspect however I’ve been working with it for months now and since I did not contact it, I discover it onerous to consider that it’s the trigger.
I’ve searched the web for this situation however I could not discover something helpful. Is there something I can do? At the least to get extra details about the place this situation actually originates from?
I took a have a look at the /var/log/ppp.log file and in contrast each instances. The principle distinction, and what catches the attention, are these traces right here:
