If you used Deco in Router mode (+1 NAT layer) behind another router (+1 NAT layer) := Double NAT, of course will be slower....

If you want to keep using another as router, then no need to use your Deco as a router behind the other router.

if your router is good/have many functions, use the m4 as AP

take a pic of your setup and post it here. easier.

can change just like this??? will it work?

It works, i am using ap mode. can change back any time. Like other mentioned if you have pic of setup may be it will be easier to see.

yeah i just change the deco to AP mode... seems working fine.. done a speed test speed quite fast faster than router mode.. i guess its setup problem

Deco M4 CPU is so underpowered even stock router is better than that at routing. Better just use it as AP instead of router mode.

understand. thanks bro

shud be 1 AP, 1 router.

agree. even my deco m9 is the same. very limited function. everything needs to be done in the app. cant even set access control, mac binding etc with it.
so better to set it as AP, and let another router handle the rest. lel

choose router
also go in settings and enable auto reboot daily and choose the right time

i always update and no problem for me

I use M4, I use only AP mode as well

and turn off the wifi on default maxis router

It is always best not to let the router do everything from a firewall, AP, routing, and file server.

The same goes for mesh.

In your case, if u already have an existing router that works, just change the operation mode of M4 to AP. Ensure u also disable DHCP on the M4 if enabled by default to avoid double NAT.

Once the router works and is online, disable WiFi too. This way, u plug off 1 potential security hole.

All WiFi businesses let the M4 handle it because u can monitor it using the Deco app.

Seems like i when i set router mode ( default) do speed test very slow.. then change to AP mode do speed test super fast. Also somehow when in router mode printer not working properly ( printer connected via wifi to the tm provided router - the black color one) when switch the deco to AP mode then printer works liao... seems like AP mode is the solution let tm provided black router do the job la while deco gives me extended wifi connection even in toilets/backrooms/kitchen etc... and also before this... the DEco M4 always lost connection by itself... and family always complain slow la etc etc.. so now i set to AP mode let's see.... did few times speed test seems ok

If on AP mode, cannot use parental control.
