Thanks for your input. Optus came out and replaced the router, the technician had seen many similar cases and suspected it was the flacky Sagemcom and that if it happened again to connect by desktop PC directly to the NBN Arris Box. The router worked OK for sometime. Then in the evening it started dropping out and eventually lost connection. The same situation the next morning and decided to connect directly to the NBN box (as suggested by the technician and your goodself). At once my link to the internet was established, steady and at good speed. After 1 hour, I disconnected and relinked via the Sagemcom to test it out. Again my PC failed to connect to the internet quickly and experienced the same dropouts. Optus said they're going to send me another replacement router (3rd one) to try. Somehow, I do not have much faith in it anymore. Although I must admit my phone line and WiFi thru the Sagemcom has never failed.
Do you have any solution? I was thinking of getting an ethernet splitter or switch and attach to the cable from the NBN box and then connect the Sagemcom to one port of the splitter/switch to provide phone and WiFi service and connect my desktop PC to another port to provide Lan access. Is this a viable solution for my situation? Looking forward to your response.
Should work fine.
Just use the WAN port (different colour) in the SageCom. Set your IP addresses so they don't clash.
I did this too with a cheap switch that just split the NBN cable to other devices.
Optus has sent me another of their Sagemcom F@ST 3864V3 router (3rd one) to try. As before it worked initially when first connected but the Lan started dropping off after a day or two. Eventually only the phone and Wifi worked consistently.
Had to seek my own solution and as suggested before bought a TP-Link Switch. Here are the steps:
1. Connected the NBN (red) cable to a port on the Switch.
2. To get internet on Lan, connected an ethernet (yellow) cable from another port on the Switch directly to my desktop PC, bypassing the Sagemcom router.
3. To get phone & WiFi, connected another ethernet (yellow) cable from another port on the Switch to the Wan port on the Sagemcom router.
Everything worked fine after that. Effectively I'm not using Optus' Sagemcom Lan to connect to the internet but directly to the NBN box via the Switch.
Optus should look at replacing all their Sagemcom routers with something more reliable and avoid unnecessary headaches and less work for their technical support staff.
My internet drops out minimum 10 times a day.
The only advice Optus give is to cycle the router.
The most pathetic service team, I've asked multiple times to review my router and why they can't see the drop outs.
It's really good when you're on a zoom trying to work from home and you switch to hotspot.
G'day @PCmoderated, its not great to see that your NBN is dropping out. Thanks heaps for running through the reset on your modem. Sometimes after long periods of usage, routers do require some further maintenance.
I would suggest clearing the line that your modem is currently connected too, just to reduce any interruptions caused internally by other devices. Once the other devices have been disconnected, please connect the modem directly to the designated socket and perform a power cycle
Simply unplug the power cord from behind the modem, doing this should turn all lights off. From there, just allow at least fifteen minutes to pass before re-plugging everything back in the correct ports.
Once the services have returned, simply connect your devices and see how you go. Just in case you have not done so already, could you also please connect your modem via the Ethernet cable provided. Generally speaking, an Ethernet connection almost always provides both a stronger and more reliable broadband service -Quade

I had bypassed the Optus Sagemcom router by using a cheap ethernet splitter connecting my desktop directly to the NBN router. For WiFi and landline they go thru the Sagemcom router which is connected to another port on the ethernet splitter. The splitter is therefore the only device connecting to the NBN directly.
Please read my earlier posts in July 2019, in particular my solution posted on 20-07-19 which Pete Gillespie agreed is acceptable.
Since then I had not a single drop out and been happily accessing my internet via desktop PC, WiFi and landline phones as well. It indicated the problem was with the black Sagemcom routers of Optus. Can't wait till Optus come up with a better more robust router.
