Hub 3000 Ethernet Switch No Longer Working

[SoftwareEngineer]

I called customer service and there was a firmware update to my modem a couple of days ago. After the update, my ethernet switch stopped working. At first I thought it was my ethernet switch, but I had bought a new one which was working fine within the first 5 mins.

After those 5 minutes had rescinded, the internet stopped working, even on devices that were connected onto other lan ports on the modem. From what I can tell there are no system error logs. I also tried to manually change the dns to match googles' 8.8.8.8.

The other weird thing is that I had configured to turn off my wifi in the bell modem, and keeps auto turning on each reboot.

Thank you for your questions. What is the current version of your modem software? With respect to wi-fi being turned on, that is normal for rebooting a modem. The modem default is Wi-Fi and Whole Home Internet on. You do have to manually turn Wi-Fi off after a reboot. There are still hidden Wi-Fi channels you can not turn off.

Hey DKS,

I called bell technical support to replace my modem to the giga modem, and I am still having the same issue. It worked well for the first 5 mins.

When I go into the modem intranet, I can see all 15 of my ethernet ports are connected. So just too summarize, I changed all of the cables, changed the switch, and changed the modem. Switched the DNS to google DNS. 

I now have a Giga Hub with firmware 

1.19.6

I've been calling bell technical support but they haven't been able to help me. I was wondering if the issue was ipv6 related.

Wifi and direct lan ports are working fine.

When I call the technical support line the "robot" says that there was an issue with my phone line due to a misconfiguration and was fixed on May 27. Coincidently that is also when my ethernet switch stopped working.

If there are no error codes displayed on the modem, try a power cycle and see if it comes alive again.

If this ethernet switch is a managed switch, make sure it's not configured with a static IP in the same range as the home hub's DHCP range.

I have the same issue.  Had to go back to the HomeHub 3000's WIFI but all the devices connected to the switch won't connect to the Bell Modem.  It was working for 2 years straight - then everything failed all at once. Tried everything to factory and set up again - nothing.  DHCP/Static on the switch - nothing. No STP - nothing. Frustrating part is it's basically acting as a hub - no routing or port forwarding or anything.  About to replace Bell.  Anyone fight though this issue and no have it working?  NetGear managed switch GS418TPP.

If it's a managed switch, make sure it's configured properly and the DHCP server is not using the same address pool as the home hub etc...

Easiest thing to try for troubleshooting purposes is to remove the switch. If you have internet connectivity after that, the issues is with the configuration somewhere.
