Hi,
I'm getting really slow speed from my M500 on hub 3. I get downloads of around 5mbps and uploads of 11mbps. This is on wired connection. Also I see the internet light green and blinking continuously. I tried rebooting several times but no avail.
Please help.
Thanks

I did check for known faults and it all shows nothing wrong. I have now changed hub3 to modem mode and connected it to my eero 6 but no difference in speed. Still getting pathetic 10 Mbps. Last night was even worse at 1mbps. At times I'm unable to use YouTube!

@athlon2005 OK that connection has just failed completely. It's probably worth trying a pinhole reset of the Hub (if and when you call up for an engineer visit, they'll probably insist on you doing this anyway), hold the reset button in for a good 60 seconds, let the hub reboot itself (don't reboot it yourself afterwards). Also just check that all the cables are nice and tight.
I don't actually have too much hope that this will resolve anything and you'll end up having to get an engineer visit. You could try calling in or waiting for a member of the forum team to get to this thread and offer to contact you directly.

Thanks @jem101. How did you figure out the connection failed from the logs? Also, does a failed connection lead to slow internet or complete loss of internet - because I have slow speeds.
