Deco M9 router on bridge ISP box does not work at all
Hi,
At first very satisfied by the stability of the M9 wifi network, I've lost an entire weekend trying to configure my network to no avail. I need help, otherwise I'll just send it back to the vendor since I cannot make use of it...
Setup : ISP Free with Freebox Delta and Devialet player, a simple TPlink switch, a synology DS220+ and connection cables all checked (and some replaced).
First try : What worked somewhat well was to add my decos on top of the existing network. I deactivated the wifi on my ISP box, plugged the decos in available slots, configured (router mode and default settings), and voilà. Wifi worked well except the double NAT configuration was troublesome to access my synology over wifi, and connect devices with my home assistant software running on the syno...
This was just to test it out, wifi stability and range was a lot better than the ISP box. Now I had to remove the double NAT roadblock. That's when trouble started.
Second setup :
- Only plugged the main Deco on the ISP box that was set to bridge mode
- Plugged the switch on the Deco's second plug
- Deactivated temporarily all antivirus options fearing it may block some things (probably not but wasn't sure)
Result was stable network, but synology completely invisible. Impossible to find in any way. The Deco did not see it, the synology assistant neither, the ISP box neither, all domain names and IPs pointing to it unresponsive.
Found that the Deco's network was 192.168.68.xx while the syno was on 192.168.0.xx so I supposed that the Synology was maybe stuck to its old IP (static but only from the ISP box settings so I don't know why it persisted). Of course tried to restart everything from the synology to every router and the box.
Also tried to reset the network configuration of the synology, no change, it stayed invisible.
Third setup :
- Changed LAN IP of main deco to 192.168.0.1 and DHCP to include syno's old IP so from 192.168.0.2 to 192.168.0.250. Rebooted everything
Result was VERY unstable network. Every device connected to either wifi or cable had trouble connecting to the internet, sometimes it worked sometimes had weird errors like timeouts or DNS not found. Tried to add 8.8.8.8 to Deco DNS setting, no change.
Figured it was probably an IP address conflict, so I tried unplugging every device
Fourth setup :
- Only the Deco plugged to the ISP box.
Result was : No change !! Could not believe it. Tried everything from reboots, trying every port on the ISP box thinking "maybe that one was reserved ?", to resetting the Deco to factory settings.
That last one broke something. I don't know why but since then the Deco only shows a red light. Cannot get the wifi up again it just won't connect.
At that point I gave up.
So, Have done everything wrong ? And if so what exactly ? What else can I try ?
Edit : I've just found the synology network reset deleted my Virtual Machine, so now basically I have to start my Home Automation again from scratch and I'm thoroughly pissed at the decos...
Thanks for any help !
