Hi. Is there any way to enable guest wifi in AP mode on deco M4? Both of the unit are connected with Ethernet backhaul.

If possible, pull an ethernet cable to your place and set another access point at your place so that you can avoid speed drop.

Else, get mesh wifi if you don't want messy cable all around the places, but speed drop might happens

Yes. Cause wifi and be affected by many variables such as interference, walls to penetrate and repeating the wifi signal might cause speed reduction etc.

Hi, TP-LINK MY

I have a deco M4 and unifi 100/50 package that is working fine. I have my slave deco connected with ethernet bachaul.

Until recent firmware update of 1.4.2, the slave deco would drops the speed from 100Mbps to 20Mbps without reason after some time. And after reboot, it will back to normal again.

Is there any beta firmware available to fix the problem or how can we downgrade to previous firmware?

TQ.

May I know you're using it in AP mode also?

You're using Deco M4 in router mode or AP mode?

There a beta firmware on Deco M4 now, you might want to check it out.

My temporary solution is to change from access point mode to router mode. After the deco reboots, I delete network from the app. Then set up everything from scratch.

It's been two days or so. I haven't face any speed reduction so far... Will report back in maybe a few days more.

Not sure this method helpful to you guys or not. Hope it helps.

Issue came back after a few days. Not sure is firmware problem or interference from neighbour.

Before update the firmware, same setup and situation also no problem.

I tried. Deco only allows downgrade from 1.4.3 to 1.4.x. Not 1.4.3 to 1.x.x.

My previous firmware was 1.1.0.

This is what they told me.



Snce I already have another router, I only use it as AP.

Fyi, I did reset and set it up as AP, but the problem still exists.

Maybe you can try and let me know.

I just realized they did update the beta firmware with different build number. Maybe you can update again from this link.

https://community.tp-link.com/en/home/forum...c/227662?page=1

You're on 1.4.2 right? You can always downgrade to 1.4.x after you update. Cause the beta firmware version is 1.4.3.

You can. I'm actually using poe to power my m4 node. But I'm using the one from d-link. So far so good.

Blacktubi did the comparison before.

Depending you have big house or not. If you do, I would recommend you get Deco series.

Deco series comes with mesh and fast roaming, which will allow you to have seemless wifi experience when moving around the house.

5Ghz is not able to cover 2 floor. You might get slow speed.

1 unit each floor is better for speed and stability.

E4 only have 100Mbps port while M4 has 1000Mbps. If you signed up 100Mbps and above, then take M4.
