You have a lot of T3 timeouts, which is not good, but your stats are okay.
Try a full factory reset of the Hub as below. You will need to split the SSID again after this.
Remove any ethernet cables from the Hub and hold the pinhole reset switch for 60 seconds. Do NOT reboot the Hub, just let it do it's thing. Note you will need the passwords from the bottom of the Hub afterwards, so make sure they are legible.
Other than this, I'm out of ideas. VM will need to check why the T3's are occurring.
