Orbi 850 running V7.2.8.5_5.1.21 dhcp issues
Hi I recently switched my Orbi 850 back to router mode from AP mode as I have a new ISP. What i've found within a day is that the dhcp function on the Orbi 850 (+1 satellite) running V7.2.8.5_5.1...
It appears to allow the amount of devices to connect via wifi when NOT a DHCP server and it is the DHCP server function that is the issue when in router mode.
....and yes I did factory reset it. ...twice.
Regarding the connectivity etc. I have worked in telecomms and IT networking for over 38 years. I understand networks, routing, subnets and DHCP servers. There was no ISP router in the new connection when initally connected to the Orbi "WAN" port. To resolve the issue in the interim I've installed an old ISP router, which now acts as the DHCP for 192.168.1.0/24 and reverted the Orbi to AP mode. It appears to have stabilised for now, but you can never tell whether all devices are working. Unfortunately that old ISP router only allows up to 32 IP address reservations.
I should also state, that over the years I've had the orbi I do have to reboot it every few weeks to keep it "reliable".
What's the size of the home in sq feet?
It is currently approximately 125 square metres, Single level 3 bedroom apartment. Previously we had in a 100 square metre two storey apartment. I'll come to the issue here, which is the DHCP function when in router mode. I can live with AP mode and rebooting every few weeks or so, but the DHCP router mode function was abysmal, and from what I've read I'm not the first person to report this issue.
For that size of home/apt. having the RBS maybe too much wifi and thus causing devices to disconnect then reconnect, ping ponging around due to over saturation of the wifi signal and to much wifi signal overlap between the RBR and RBS, causing DHCP services to get up in a bind while having that many devices connected, going on and off line.
Distance between the RBR and the one RBS?
