This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hello,
I'm having problems with several devices who are connected to internet via my Deco's. Connections that stop, freezing of streaming, camera's that disconnect etc.
I already reconnected the main Deco to the providers router (connected via ethernet cable directly to this) and I restarted the satelite deco's many times.
Still no change.
But what is weird, when I check the speed up and down on my units it changes constantly from nearly 0 to way above 600 Kbps. First I thought it was only on the satelites, and that it had something to do with the transfer of the wifi signal, but also on my main device I see those weird changes, every other second another speed. But the speeds I see the most remain way under 100 down and under 20 up. I even have 1 Kbps down and 1 up.
Is this normal? Or is this the origin of all the problems with my devices that get disconnected or that freeze?
Thanks for your help!
I will give you recommendations on how to make your Deco mesh work better, and they will be based on what I did at my house with my Deco M9 Plus. But I must say, your Internet speed which is 8Mbps/1Mbps could be too slow to handle two TVs streaming simultaneously and security camera if it uploads video to the Internet.
Other than that, you have good Deco hardware which can support Internet speeds up to 500Mbps.
What you see in Deco app is current network utilization by different devices. This number will fluctuate, and it is not a symptom of issues. If device sits idle, speed will be zero or close to zero, for example.
Deco tries to guess what devices are on the network, and 'Texas Instruments' could be anything: TV, etc. If it is shown as inactive, this must be device which is not always online, or perhaps you had a guest at your house who you let use your WiFi and who left your house.
You can delete these devices from list of inactive devices. If they appear again and do annoy you, I'll tell you how to figure what they are.
There will be multiple steps in tuning your Deco mesh, as I don't want to make one very, very long post. We can start with ensuring your Deco mesh runs well, and next time I'll start giving recommendations on how to improve performance and stability of individual devices connected to WiFi mesh.
This is what I would recommend you to do:
1. Turn off WiFi in your Sercomm Livebox 4. You don't need it, as WiFi should be provided by Deco mesh only.
2. Open Deco app, and each of Satellite Deco pages. Each Satellite Deco reports its Signal Source, example:
If you see three or two blue bars, it means Satellite Deco has good connection to Main Deco. They should, judging from your map, but it is worth to check.
If you see one yellow or red bar instead, that Satellite Deco is too far from Main Deco. When that happens, devices connected to such Satellite Deco will experience connectiviy issues.
3. Sercomm Livebox 4 is a router, based on its description from the Internet. It means, you can let it keep managing your home network and can configure Deco mesh to run in Access Point mode to just provide WiFi signal. This should help with troubleshooting, and also simplifies your home network.
Follow this document: How to set up Deco to work in Access Point mode
After you made that change, you may need to reboot (power off/on) some of devices you have which won't reconnect by their own. This is just one time, after they reconnect they should work just fine.

After you've done with this, let me know and next step will be helping individual devices to have stable connection to Deco mesh.
Sorry, yesterday didn't work to post my info
I have made a drawing of the positions of my Deco's
2.
I have three Deco's
The main Deco is in the hallway, as high as possible, connected to the providers router by ethernet cable.
The second Deco is at approx 4 meters from the first, standing on a cupboard to have it high as well
The third Deco is at approx 7 meters, at the end of the hallway in a direct vision-line with the first, also standing on a cupboard to get it as high as possible.
The walls are approx 5cm thick, no metal or concrete, single brick walls.
3.
I tested their speed with the app on my phone, tapped the globe to get on the page 'all deco's are online', then I tapped each unit and checked their individual speeds.
On the main Deco there are generally 5-7 units listed (depending where we go with our phones), on the second one there's three listed of which one is always active (with a number like a phonenumber but I don't know that number, could be Hue Bridge) and on the third there are three units listed.
On all three there's 'Texas Instruments' listed but all inactive, no clue what these are.
4. & 5.
I have a Sercomm Livebox 4, ADSL connection. Speed 'delivered' by the provider according to their info 1020 Kbits up and 8226 Kbits down. Speed this morning according to Speedtest 0,82 Mbps down, 9,92 Mbps up, ping 27 ms.
I did the speedtest in the app, two times on automatic server and two times on my providers server (Orange France).
Speeds: 6,4 up 1,1 down / 7,0 up 0,8 down / 5,6 up 0,7 down / 7,0 up 0,8 down
So for my there's not much difference I think
7. The problems are really very regular on the two tv's when streaming (freezing or loosing contact for some minutes or even not connecting to wifi at all) but also our security camera's keep loosing connection and reconnect again. One of them is next to a Deco unit, at approx 50 cms so not so far away that it would loose connection.
I hope this gives some indication on what could be wrong or what I could do about it.
Thank you!

You should see "MESH" button for all devices wirelessly connected to Deco, and it will not be shown for devices that are wired by Ethernet cable. We may need to use that button later, but for now keep it enabled for all devices that have it in Deco app.
Texas Instruments company provides chips for WiFi access for devices. You won't see it on smartphone, so this is likely WiFi enabled appliance such as security camera, dishwasher, etc. They connect to WiFi and Deco recognizes them by their WiFi chip.
If 'Texas Instruments' device shown with MESH button, it is connected wirelessly, without - it must be wired. That might narrow the list of suspects.
You can also find what are these devices by placing them in Deco app Deny List, which is under More in Deco app. Add such device to Deny List, and it'll lose Internet connection. See what suddenly stopped working. When you figured what it is, remove that entry from Deny List and device will start working again.
By the way, do you know you can rename devices in Deco app? Comes handy in situations like this: after you figure what that 'Texas Instruments' is, you can give it meaningful name in Deco app.
We are going to use Deco mesh Guest network to improve WiFi connectivity for your devices. Older devices such as security cameras and TVs don't like when WiFi signal is broadcasted on two bands (2.4GHz and 5GHz) under same WiFi network name (SSID). We are going to fix that, by splitting these bands.
The configuration is under More/Wi-Fi. Keep Guest Network enabled, make sure it has password (it can run without it, but you shouldn't let it to) and choose for it same Security as it is on your Main Network. You'll have the following configuration:
Note "Isolated From Main Network" toggle is OFF. Make sure it is OFF in your configuration.
After you've done that, some devices (such as security cameras and perphaps TV) may refuse to connect to Main Network. This is because they can only run on 2.4GHz band. On each of these devices, configure them to connect to Guest Network name (SSID) with Guest Network password.
-------------------
With that, you will be having more stable network. Let me know after you made these changes and the next step will be to deal with devices which still lose connection and reconnect.
Also, in the future TP-Link will release firmware upgrade to Deco M9 Plus which will make this type of Deco mesh tuning much simpler. Till then, alas, this is the only way.
Hello,
I'm working on it. Found the possibility to stop the 5Ghz but as soon as I do that, my indoor camera doesn't connect anymore.
Funny thing is that when I check the app it's connected to the main network and not to the guest network so actually it shouldn't disconnect at all.
Trying to figure out now how to connect it in a forced manner to the guest network. My camera's indeed only function on 2.4, I checked the manuals.
BTW, I found the TI devices, they're my heat pump indoor units, I changed their names now 
.
For the mesh toggles: I only have one device connected with ethernet, our Hue Bridge. But that one doesn't show this toggle at all. All other devices show on/off toggle for mesh.
So I'll continue to get my camera's switched from main network to guest network to connect to 2.4Ghz only.
I'll be back!
Goodmorning @Alexandre.
I give up. Tried tens of times to connect my camera's to the network after switching off the 5ghz.
It really doesn't make sense, my camera's are both connected to the main network, 2.4 Ghz but when I switch off 5 Ghz on the guest network they both disconnect and refuse to get connected again, no matter what I try, not on the main network anymore nor on the guest network.
So I guess optimising the wifi system by setting the guest network to 2.4 Ghz only won't work.
