And the other interesting thing - on the Sagemcom website there is no mention of a product called 5366 TN. There is a 5366, but it isn't a TN and it looks quite different, and it's for FTTH, not FTTN. So maybe this bit of hardware is very new? That could explain why there aren't that many complaints about it. Yet.
Today we found there were firmware updates outstanding for our two wifi repeaters. Downloaded the updates, updated the devices, they wouldn't adopt. After much stuffing around, realised this was the same problem again - the DHCP in the modem wasn't giving them an IP address. Turned the modem off and on again - all OK. Just looks as though we have to turn off and on again about once a day to avoid connection issues. Not what I would call a satisfactory solution.
I think I must be a masochist. I tried the Optus chat line again. They have promised me a call from a real live person in the morning. They also gave me a contact number for sagemcom. Just in case anyone else wants to have a go, it's 133 937.
I'm having the same problem but it only seems to affect connections on the 2 GHz WiFi.
My iPhone can connect on the 5 GHz band, but not the 2 GHz band.
There are only 12 devices connected right now (which may suggest that the "16 DHCP device" limit isn't correct".
I am also having a similar issue. My internet (FTTN) was working fine except that the upload speeds were not what they were supposed to be. I was getting 43/10 instead of 47/15 I then contacted Optus Technical Support and was told to do a RESET to Factory Settings. I then went to 0/0 (Status: Disconnected).
For the Optus technicians please see reference number: 22522919
This is the second Optus Router in the last 2 weeks. I have also had both NBN and Optus technicians visit. The NBN technician said that they were measuring 50/15 all the way to my router.
This has got to be a software/firmware issue as the as the hardware has been replaced an was actually working for a while.
Please let me know if there are any updates on this issue.
Thanks for providing the ticket number, third_miles.
Last update was from Saturday when they made contact with you performing various troubleshooting.
Monitoring the various devices over the weekend with a follow up call back scheduled (not specified).
