For wired Backhaul this is what I follow & has worked always

Thanks a lot for this

Yes, wired backhaul will most definitely give you the full speed. Wireless backhaul will have to share the available bandwidth, I don't think there is a dedicated radio for backhaul on the X20. Secondly as you said, the master room has a known issue with wireless signals in general, could be something blocking the signals from propagating properly.

So if you have existing conduit from the main deco to the master room to pull a cable, by all means go for it, you won't be disappointed.

Cool thanks once again

One final query, would you have any idea if the resonate 12V router UPS will support this switch?

or can you suggest any router UPS for this switch as i see it needs separate power coz all my decos are connected to router UPS for un-interrupted power supply

IIRC Deco devices have a dedicated wireless backhaul. There is also some settings in the App regarding dedicated wireless backhaul. Not sure though.

Also, having a dedicated wireless backhaul doesn't mean you'll get full speeds. As @MrGordon said, it depends on a lot of factors, mainly the wireless signal strength and interferences.

Instead of buying a new switch, you can also use the C5 as a switch. Just don't use the WAN port on C5. If you want, you can reset the C5, set it in AP mode and disable the wireless radios on it. Then it is just a unmanaged gigabit switch.

And yes, getting wired connection will definitely give you 400Mbps speeds since you're already getting 400Mbps at the other 2 Decos.

So

1- Power on the C5
2- Reset with a sharp Pin
3- Connect C5 with ethernet wire to Laptop/Desktop (Minus WAN port) while ensuring Laptop/Desktop isn't connected to Deco internet
4- Go to admin webpage with its ID Pwd of C5
5- Disable WLAN
6- Put operating Mode as Access Point
7- Connect with Main Deco now via any other port minus WAN port
8- Take connections out of of remaining ports minus the WAN port

Am i correct here?

@tartarus That particular switch uses a 5V DC input based on the specifications. So a 12V router UPS will not work. I think most basic switches would use 5V.

However, you could also repurpose the C5 as a switch, with everything disabled.

May be ill buy a normal router UPS and use C5 as switch then since it will make things easier for me

@tartarus I would suggest a slightly different approach.
1) Power on C5.
2) DO NOT RESET
30 Loginn and turn off Wifi Radio
3) See if you change tp AP in Settings, if not then reset the C5 after taking a back up of the settings of the device
4) The above step will let you have a back up in case something fails at a later day
5) Then steps 7&8 to close it

The UPS i think you will need a 500 or 600 KVA for both the C5 and Deco X20 and then oakater for others will work better

Hi bro once again you, Gordon and John have been life saver for me

I completed converting the router to switch, so will be using Amazon Basics/Oakter 12V UPS now

Parked the C5 as is, just in case this setup acts up someday and ACT guys blame me, i can put the C5 back on

I saw some videos on YouTube and I had an old Tenda AC1200 which i converted to switch,
Connected Tenda to Desktop via LAN port
Just disabled DHCP, assigned an IP to it, basically Tenda had default 192.168.0.1 and primary deco had 192.168.xx.a so i made Tenda's IP 192.168.xx.b
Manually assigned a temp IP to desktop instead of Auto going into Network settings after changing IP of Tenda since it wont load as DHCP was disabled and Tenda could no longer assign Desktop IP
Then disabled Wi Fi
Changed Network settings (IP assignment) in Desktop back to Auto assign
Connected Ethernet from Primary Deco to LAN port 1 of Tenda
And Done

I did check other devices connected to Deco so as to not duplicate an used IP

Let me update the thread tomorrow once the ACT guy completes wire routing to room and i connect the 2nd Deco in wired mode from Tenda

john1911 said:

You should set the local IP of Tenda outside the DHCP range of Deco.

BTW how much did you pay for the Deco X20 3 pack?

How do i check the DHCP range?

And its same as on Amazon 13K i think

john1911 said:

GM

In the Deco router configuration page, under LAN settings, there would be DHCP range -

Router IP: 192.168.1.1
DHCP Range: 192.168.1.2 to 192.168.1.100

or something like will be there.

It means that the router will assign any free IP from 192.168.1.2 to 192.168.1.100.

So any static local IP should be outside this range to avoid any probable IP conflict.

Will check this after work today

Also @john1911 instead of that wont it be better to use the addresses reservation in Deco app under more and then advanced setting

It allows to assign one particular IP to one particular device forever

@MrGordon @john1911 @kiranrss

Happy to report all the rooms are now wired backhaul and getting the promised speed by the ISP

Thanks for all the help and i hope this thread helps someone else in need in future and also thanks for helping me save some money by not buying an extra switch
