Do you know what all those tiny spikes are from? A combination of web and default. It looks like some device or devices are communicating briefly every 15-20 minutes.
It is nowhere near to saturating your line based on your 300/30 connection. When this happens again, check your Gateway Graph at Status->Network (others). This graph should be pretty smooth almost all the time if QoS is working well. If you see tall spikes centered around the time you are having problems, that probably means that some buffer somewhere is getting “bloated”. However, if the gateway graph looks smooth and your QoS graph shows bandwidth use well under your ISPs limit, it could also be that something outside of your control is responsible for for the pixelated video (or whatever issue you are experiencing). Meaning, it could be on the ISPs end or any hop between you and your destination. If it was on Christmas Day, it could’ve been due to congestion from everyone else in the world using it at the same time.
My son or wife will sometimes complain that the internet is slow, or keeps dropping. Whenever I check IPFire during those times, it’s usually the case that everything on our end is fine and whatever they are experiencing is originating on the remote side.
White (blank) gaps in the gateway graph indicate no connectivity with the ISP gateway. Here is what an ISP outage looks like:
If you don’t see those, you know you are successfully pinging the gateway and there are no “drops” occuring between IPFire and the ISP gateway.
Tall spikes on the gateway graph indicate slow pings to the gateway, which usually means buffer bloat is occurring.
Your first post inspired me to update my 10 year old post on QoS customization. Have a read here:
Yes, the N5105 is capable of 300Mbps with QoS on. I have that cpu in one of my IPFire devices.
