@MarvinZH I'm running the Deco M9 Plus as well, updated to the latest beta combined with the 3.0.19 app. I'm using wired backhaul.

We seem to be in the same country, so I did a speedtest and get no real difference between connected directly to the M9 and connected to my ISPs modem.

I'm not using any QoS.

First speedtest = connected directly to the main M9. Second speedtest = connected to the modem. Both through two switches.

There's no speed drop since upgrading the firmware, with other speedtests than Ookla I can easily max out my 1Gbit/1Gbit connection.

I think that the 20-30mbps difference is neglible, if I run repeated tests, I get slightly different values but never such a huge difference as you're showing.

I don't think your issue is due to the firmware.

  @David-TP The speed has dropped since the update to 1.6. I'm doing the speed test through the main M9 deco. QOS is at 1000/1000mbps. When I do a speed test through the app I get this result.

  @Ghostcheeks If I do a wired test via the Deco M9 Plus, the speed is not the same as with another router...?

Can you please add Connection Preference for Guest Network? 

 

This feature is already available for main network, we just need it to be available for the guest network users too, it will be nice to control 2.4/5Ghz and preferred unit for these users too. 

 

 

Please tell us if it's even something you consider adding in the near feature or not?

+1 for this feature.  For security, I have many IOT devices connected to my guest network.  TVs, cameras, other IOT devices that I want to keep separate from my computer network.  These are the devices I MOST need to be able to choose a connection preference for.  For instance, I have a TV that barely functions because it insists on connecting to a node that is on the other side of the house.  Yes I can force connect it by turning off the other Decos and disabling mesh, but I have over a dozen of these IOT devices that I would need to do this with - and more getting added all the time.

 I've been dealing with chronic slowness and dropped connections since updating to 1.6. After exchanging a ton of emails with support, disabling 'fast roaming' in the advanced settings seems to have resolved my issues. Internet is back to being stable, no dropped connections in the 18 hours since (compared to every other minute leading up to it) 

  @David-TP 

I have version 2.8 and it refuses to update from 1.56 to 1.6. I already reboot multiple times and made sure it's the only pod connected wirelessly, set the main deco using the other pod, and disable the third pod. The other 2 pods I have that were version 1.2 did not have this issue updating to 1.6 from 1.56. 

  @David-TP I've started getting frequent slow internet or one of the satellites appearing offline in the app. requiring one or more reboots to fix

  @xQuantum I see that this thread has stopped working. Can you provide more information about the beta or if the official version has already been released? 

  @David-TP 

Thanks for the reply. 

It's getting a kind of funny 😁 that, 1 year (12 months, 365 days) after the previous alfa release, there is still no plan for a next version.

So, your delay in responding is where TP-Link stands for.

Fingers crossed we have an update when WiFi 7 is introduced into the market.

I think it is clear the TP-Link doesn't have plans on providing what THEY EVEN ADVERT ON THEIR BOXES.

300% commercial stuff without a plan and customers are left behind.
