Intermittent loss of internet connection RBR 350
I have the RBR350 with two satilites. I was getting the odd loss of internet on WiFi message. Rebooting the modem/router, a Sky Broadband Hub, worked. This was happening every couple of weeks. Now itâ...
Sorry for all the questions. Should I select static ip or dynamic from ISP ?
(sorry, I've been away from the computer)
Using the Dynamic Host Configuration Protocol (DHCP) has been around since 1993
(https://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol )
It is very common for devices to hand out a leave for 86,400 seconds (one 24 hour day). The protocol expects that device to attempt to renew the lease when 50% remains (12 hours), and to keep trying until it finally expires. This situation gives an impression that communication with the Sky Hub is not behaving correctly. Could be the Hub. Could be the RBR350 router.
I'm a bit puzzled, because the typical pattern is for the lease to expire 24 hours after it is issued. No one is likely to be on hand to reboot the router immediately after a lease expires, so one would expect the expiration time to shift.
It would be helpful to know the IP address on the Orbi router WAN interface. On the Orbi web browser interface, the Advanced Tab, under Internet Port the "IP Address". If it is a private IP address, then there would be no problem changing the router to a Static IP.

No need to apologise my friend I very much appreciate your help. We all need a life outside our computers đ
I was a network engineer and then project manager, I retired in 2016, so I am a bit rusty.
Bit more background. I got the Orbi in June, very impressed, then around September I think there was a firmware update and I started to get loss of internet via wifi every couple of weeks. Then when the firmware updated again a short while ago it changed to a daily event. So I blame the firmware which looking at other members who are having the same problem seems to be a bit of a thread. But yes, static IP is the answer. If it will work with my modem/router. Anyway first things first
Under Internet Port , IP address is 192.168.0.62
Took a leap of faith and change IP to static as 192.168.0.62. Everything is working OK, so far. Connection status has disappeared under Router Status, Show Statistics and no sign of "Lease timeout"
Did I do the right thing ? đ
What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.Your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktopTry option #2 first...

As FURRYe38 remarked, when the Internet Port is a private IP address, that is an indication that the ISP device is also a router (not "just a modem"). Which means....

This is not correct. If the ISP device was in modem only mode, the public IP address would appear on the Orbi router.
Being connected to a router creates that dreaded "Double NAT" situation which can interfere with specific internet applications. When this happens, the user is acutely aware that a specific thing they want to do won't work and the solution is to do one of the things suggested.
It is hard to understand how a protocol that has been essential to computer networking since 1993 could be failing. If setting the Orbi router to a Static IP "fixes the problem" (which you should know in a couple of days), then you have some choices:
- Leave things as they are (Static IP) and stop fussing with the Orbi.
- When new firmware comes out, change back to regular DHCP and see if things have improved.
- Take steps to remove the Double NAT and see what happens next.
- Try to get either Netgear or the ISP to admit that their device is faulty. For example, I would tap the Ethernet connection between ISP router and Orbi router and use Wireshark to capture all the dhcp packets to see which of them is not acting correctly.
If the problem remains even with the Static IP, then the problem is "something else".
Why I asked about the model# of the modem/ONT and to confirm the format of the IP address seen on the RBRs internet port.
