Deco M5 WiFi slow after recent firmware update
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I noticed a significant drop in download speed on my Decos after recent firmware update to 1.4.4. Both 2.4 GHz and 5 GHz bands are affected.
Normally wifi on my modem/router is turned off, Decos are in AP mode.
Topography is modem/router->Main Deco via ethernet cable->Slave Decos via wifi
If I switch off Decos and connect directly to wifi on my modem/router, I get around 86-94 Mbps down and 35-38Mbps up. Before the upgrade, I was getting these speeds with Decos as well. The link is 100/40 Mbps.
After firmware upgrade to 1.4.4, I am getting 48-55 Mbps downloads on Decos. I get these from speed tests on Ookla, choosing the nearest server. When I use the Deco app speedtest, it gets better results, but I don't think they are relevant.
I tried downgrading via the web interface to the older firmware, but the downgrade wan't allowed.
Please helpt to downgrade or fix the slow speeds.

@Tony Thank you. Deleting all the nodes from the network in the Deco app, then restarting everything fixed my issue.

I will try that and report back. Any word on a new firmware version to correct this bug that came with this firmware update?

I have now experienced this same issue on v1.4.4 of firmware and my wifi connections have become erratic and speeds are dropping conistently
I have reset each deco using the nodes reset pin, and reset up my entire network again from scratch (needed to do this anyway as was also experiencing the issue where the mobile app and even the web interface would no longer allow me to make changes!! - i.e couldnt rename a connected device or turn on and off its high priority or mesh function), since restarting the network from scratch I am no longer having the app issues but I am still experiencing these wireless dropouts and erratic speed issues.
There is something not right with firmware 1.4.4

Update:
I have tried turning off the 5ghz channel and this had no real effect to my speeds
But turning off one of the two slaves deco M5's (doesnt seem to matter which one) seems to have made the WIFI far more stable and I am now getting far higher speeds

With firmware there is no current information only that if users experience a slowdown default usually put it back to normal.
Your issues seem to be more than simply defaulting the Deco device. You can try swapping the main Deco with another to see if the problem is with one of the nodes.

If I swap the main device do I need to re-initialise the whole of my network again..... IE lose all my settings and start afresh?
I have run with just the two decos and can confirm it has made no difference.
What has made the network a little better is using all three again but turning off the 5ghz wireless channels
I will try your suggestion on Sunday, when the network will be less in use.
If this fails I will downgrade my firmware to the Nov release and see if that makes any difference....

When you swap the nodes the app should recognize that the main deco is no longer connected so it will prompt you to designate a new main deco. You will need to look below the new Deco to see the MAC address so you know which one to choose as the new main Deco. All the settings will still be saved.

@BigE0n I think it might be my ISP, but when I switched to a different master deco, I got no connection at all. I wonder if my ISP registered the MAC address of my master deco and wouldn't let another one take its place. As soon as I switched back to the first main deco, I got service again. So if you run into something similar, you may need to contact your ISP.

Well I swapped the main deco, and completely recreated the whole setup from scratch again! And all was fine until the evening when again my wireless connections became erratic and my son's Console dropped to 1mb download!
I have found that going into the deco via the web interface and rebooting all the decos sorts the issue out for a little while but then it resserts itself again over time
Did a bit more messing around / investigation, and it's definitely related to the 5ghz channel, this seems to drop through the floor, and devices don't switch to 2.4ghz at all which is now running faster!
Even when this is occuring if I goto the app and run a speed test it shows the deco is receiveing 110Mbs down and 11Mbs up!!! so there is defintatly no issues with my ISP
Whilst messing around I realized that this seems to have manifested since I reconfigured the QOS, from the default standard to my own custom one!
I am going to run on standard for now and see if this helps aliviate the problem
Just a note since the android app updated itself this week, SIP ALG was default back to ON, even though I had previously disabled it
If this continues I will rollback to the previous firmware
I am on deco M5 v1.0s just incase thats of any help
