>i removed every other deco from the network (unplugged - left only main one in use - no difference)

 

Have you tried this with Main Deco in Access Point mode?

I havent, but i dont see how it would change anything? Ill give it a try though, but my previous WiFi routers have all been in router setting and they worked fine!

@Mark_Deco-M9v.2 

 

This may help to narrow issue to either Deco hardware or specific Deco software running in Router mode.

 

If in AP mode the issue does not happen, it is TP-Link software or software configuration issue. In AP mode Deco is not much more than signal booster.

The Huawei 4G Modem is not compatible with AP it seams as switching Deco to AP mode caused a full meltdown! No computer connected to it as there was IP issue and other satelites stayd blinking red and Deco was unreachable (main deco had green light) Finlayy when i was able to log back in Deco had reverted back to router mode (probably due to the issue)

@Mark_Deco-M9v.2 

 

So the AP mode didnt work, as all devices said that there was IP error like everyone was trying to log in and use exact same IP, now got it back to the router mode, but errors have not resolved. Nothing has been changed and now all of a sudden everything is down - very annoyed.

EDIT: Is there a way to pull a log or something - it is just stupid, after restart thing worked for 2 minutes (everything loads super slow and with errors - images not loading on pages etc) and then red light - all decos are offline, then greenlight but im assuming the "boot up" or whatever goes on after the green light comes back up takes so much time and confuses devices that they are pretty much unusable - google might load or might take 2min to load or might give you error no internet connection.

 

EDIT2: This is what the app shows for 30seconds or so when the red light comes on

This could have been good test, but it requires network configuration to support Deco in AP node. Yours is not, so you can't test it.

 

I noticed your Deco M9 formware is version 1.2.11. Mine, in North America, is version 1.4.3 build 20200921. Check if version 1.4 is available in EU for M9, if not yet - perhaps TP-Link Support can provide you with 1.4 beta to try.

Hey, within the app "Update Deco" it says that it's the latest firmware! I have seen so many others having similar issues :/ Yours is working great? I mean mine was also, but since today its unusable, perhaps only as a paperweight.

@Alexandre. 

 

Actually, this is how you could still test Deco hardware if you are willing to give it a try:

 

>4) yes i tried another wifi router instead of Main deco unit and other wifi router has good connection with modem and worked fine

 

1. Attach that "another" wifi router to modem.

2. Power off all Satellite Decos.

3. Connect Main Deco to wifi router.

4. Now that Main Deco is connected to router, you can switch Main Deco to AP mode.

This is latest firmware they have on UK TP-Link web site, for example:

 

@Alexandre. 

 

Yeah I checked - my app shows nothing, i download the update tool and went as per instructions, it said that deco units will be rebooted to complete the update but no update was actually done.

 

App still shows old version, im unsure if its some region thing or what its about.

After the update - same red light error still pops up

Firmware version
1.2.11 Build 20190926 Rel. 55727

Is there a way to get it to update via the app somehow? Anyone from TP-Link support perhaps could help with it?
