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...
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

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.
Thanks guys. I had turned the WIFi off on the modem/router which is an ISP supplied one. I'm in the UK and it's a Sky Broadband Hub. I have the options to turn off the WIFi AP, and broadcast SSID which disables the Wifi. With the Orbi set as router. Not forgetting the Orbi was working fine until the last two firmware upgrades
I'll get back to this tomorrow but again I really appreciate your help
Turning off the WiFi radios doesn't put the modem/ONT into bridge mode or set modem only mode on this unit. Just turns OFF the wifi radios, still leaving the router portion running and enabled. Why it's important know what the RBR is getting from the ISP modem. If the modems router is still running, this maybe causing your problems. Try the option#2 to see if it helps any.
I would out of this modem has a actual bridge mode that is supported. If not, then you'll need to use the DMZ on the modem or set the Orbi system to AP mode. Something else to try to see if the Orbi system sees this loss of internet while in AP mode.
Thought I would update, especially given the great help I've received
Firstly apologies to anyone reading this who is in the UK as you'll know all of this
Some background in case you don't already know this. I'm in the UK and the broadband/phone supply is very different. Original ALL phone services were supplied by British Telecom, BT. In the 80s they were privatised and had two divisions Openreach for infrastructure and BT for everything else. They were awful as basically a state run then private company monopoly and customer service was poor.
However once competition kicked in it became more interesting. But today most backhaul infrastructure is still run by Openreach but they now have to open their exchanges to everyone to install their own equipment. Also most wire or fibre to cabinet or premises is still owned and maintained by Openreach.
Apart from a couple of fibre (cable) to premises companies, BT, Virgin Media and Trooly and maybe a couple of small ones, most homes have either copper wire to carry phone and broadband or fibre to a local street cabinet and then a short run of copper to your home. The latter limits speeds to typically 70Mbs but varies. Most ISPs use PPPoE as a DHCP authentication method. But one, just one, the one I use Sky use MER (Option 61). Oddly in Ireland Sky use PPPoE, go figure. So unless the modem/router has Sky MER as a choice in the ISP menu in setup it won't work. As it can't communicate with the ISPs server. Some do such as the TP Link VR range. Crazy as also ISPs in the UK don't allow their supplied modem/router to be set in bridge mode. Unless you buy your own modem/router of course but again you have the MER authentication issue if you are with Sky who are one of the biggest broadband suppliers in the UK.
I didn't realise that a mesh system needs this ability as well to act as the router but now I understand that they do. This I believe is my problem with the Orbi. It can't re authenticate the IP with Sky so will drop until rebooted and a new 24 hour IP lease is issued. Repeat ad nauseam.
I could set the Orbi router to AP mode and that would work without much loss of important features. Even if I chose a TP Link modem/router which do have the MER option I would still have the same issue although it could then be set in bridge mode unlike the Sky device. Not sure even then if that would solve my issue though...does anyone know ?
So at the moment I am stuffed without a lot of messing around so have sent the Orbi back to Amazon. I am gutted though as when it worked it was brilliant. I can't explain why the drop out issue got worse after the firmware updates. But it certainly did as for the first couple of months I didn't have an issue.
So long post but thank you for your patience and help. I will switch supplier in the new year that uses the more common PPPoE DHCP system Then I'll be back to Orbi
