I am experiencing issues with my internet connection. The connection has dropped approximately 10 times.

A speed test was performed, showing a download speed of ₄₅ Mbps and an upload speed of ₆₀ Mbps.

The modem was reset, and a direct LAN connection was tested. The diagnostic tool did not detect any abnormalities.

Is there any information that UPC can provide from their end?

Thank you for any assistance.

hutt Everything is fine with the modem signal. We see that you are using a Gateway USG? Does this device have an integrated firewall? If so, you could set your Sunrise modem to bridge mode according to these instructions.

hutt

Daniele_Sunrise Correct. Yes, it has. Is there any relation between the speed issue and bridge mode?

Daniele_Sunrise

hutt No, you have the same speed in bridge mode, but no more double NAT, which can also slow down the line. Please test it once and report back here.

Daniele_Sunrise Apart from devices connected to USG, we have devices connected to UPC modem via LAN directly too, would that be still okay to use Bridge mode?

Daniele_Sunrise

hutt No, all devices should be connected to your router / firewall in bridge mode, otherwise you will have too few public IPs and some devices that are connected directly to the UPC modem in bridge mode will not come online.

I cannot use the bridge mode because we have to use the LAN of the UPC model due to distance issues for a few devices. Thank you so much anyway for your explanation.

In order to sort out the double NAT you should just setup a switch where the USG is.
And let the UPC Box in Router Mode.

maxell182 it is in router mode. Disabling NAT on USG would be also an option?

If you don’t want to get a switch, you have to disbale: DHCP (forward the DHCP), NAT, DNS on the USG and konfiugure the WAN Port to Static IP from the UPC Box.

BUt, no clue if this would work. If you google this setup (USG behind router) there are some posts which state, that its not working out of the box and you have to ssh into the USG and make some config changes.
