Slow Deco M3W in a Deco M9 Plus Mesh
I have a Deco M9 Plus 2x pack (1.5.2 Build 20210223 Rel. 35265) running as in a Mesh network.
When come to a "slow Internet speed spot" (not exactly a blind spot) in the house it is slower for some WiFi devices.
And so I purchased and installed a Deco M3W (1.0.7 Build 20210106 Rel. 65893) hopefully to boost up the signal and hence WiFi speed.
After the deployment, to my disappointment, a Internet speed test using my mobile at the "slow internet speed spot" of the house:
- Through the original WiFi of the Deco M9 Plus - 23Mbps/171Mbps UP/DOWN <--- FASTER!
- Through the newly deployed WiFi of the Deco W3W - 23Mbps/52Mbps UP/DOWN <--- SLOWER!!!!!!
What is wrong with the Deco M3W, where it is deployed to stronger signal and hence speed, for 1/3 of the download speed?
It's making it worse than improvement! I don't use QoS nor Fast Roaming.
Any suggestion? Thank you.
If Deco M3W is not helping to speed up I will have to return it.
