My plan is 200 down/Up and I used to get full speed over WIFI by being near the main deco.

But after updating to the latest firmware I'm not getting the full download speed over WIFI even if I'm closer to the main deco unit.

Now that I have done the ethernet backhaul I do get full speed on the computer,

but over WIFI even if I"'m close I don't get the full speed that I used to get.

This has been happening since the firmware upgrade. 

What to do to get full speed over WIFI  which I used to get,

or should I wait for the next update? Thanks.

Also :

1. I have disabled the QoS.
2. The dual-band is on set to both bands and I used to get the whole speed even if it was on both bands

Speed after Backhaul and Connecting the ethernet to my Desktop.
