Have you made the changes suggested in this thread?
Ronski, am taking this a step at a time just so I can see where I get to.
Previously I had modem mode enabled and I would lose the internet for approx 1 min at least once an hour. After switching to router mode I did not lose internet anymore but as per my graph I am sure it could be better!
Steps taken so far...
1, Factory reset on pfSense
2, Factory reset on SH3
3, Switch SH3 to modem mode
4, Set on "All IPv6 traffic will be blocked by the firewall unless this box is checked" - I don't use ipv6
5, Added icmp ping rule on WAN
6, Tested ping from external
7, Reconfigured BQM
I will post my next BQM in 24 hours and will put side to side to ones above.
Only diff to before is I am on 2.4.5 p1 instead of 2.4.4 p3
Will be interesting to see if I get drop outs tomorrow when working from home.
In reality, I am aiming for my neighbours graphs - yours is pretty perfect - did you actually use the internet that day!?
