For a few weeks I've been getting random packet loss throughout the day which is only really noticeable when gaming as it only lasts a few seconds.
I used to run my Super Hub 3 in modem mode connected to Google WiFi but have since reverted back to router mode to try to rule out any other hardware being at fault so my current setup is just my super hub 3 plugged directly into my PS4 and PC. Other 2 ports going to a switch which connects a couple of other devices and a wifi access point.
I've started logging any drops using an application on my PC so this is from running the application this evening so far:
It's worth noting that there have been many many issues in my area (area reference 31) over the past year and everyone in our area regularly gets complete internet outages which seem to go on every day for a week or two, then suddenly gets resolved for another few months only to return so it may be related to that.
SNR I believe is just in spec, but looks to be very much at the low end of what you'd want to see, power levels seem within spec, but have quite a wide range from +2.5 to -3, and the error performance is a concern. Reboot the hub (this should reset the error counters) and see if they keep climbing over the next day or two, if they do hold on until the forum staff come to this post, because you'll need a technician to sort out the line. In the meanwhile make sure that the connecting cable between hub and wall box is securely tightened at both ends, if it is loose than can cause problems. I wouldn't be surprised if your speed is a bit down, and latency may be poor due to all the errors.
For comparison, my Hub 3 has a nice even SNR of 38.6 to 38.9 on all channels, power levels +2.9 to +4.5 and the error count after two weeks uptime is about 40 pre-RS (corrected) errors on each channel and a single post RS (uncorrected) error on one channel.
You may also want to set up a Broadband Quality Monitor at Thinkbroadband.com to continuously monitor the performance of the connection. As that is pinging your Hub 3's modem, it is entirely independent of your wifi arrangements.
