HI,

I have recently bought 3 x E4 units. The maximum speed I can get from my modem is approx. 80Mbps. I am happy with this.

The majority of the devices I have connected via WIFI vis the DECO units are 5 GHZ compatible.  But I have an older mobile and laptop that only works on 2.4GHZ frequency.

If I do a test in same location with 2 mobiles( 1 on 2.4GHZ, the other on 5 GHZ), the wifi download speed is almost maximum at 80Mbps with the 5 GHZ network and approx 35Mbps with the 2.4GHZ network.

In the firthest location away from the Main Deco unit, the 2.4GHZ frequency mobile often drops out or is very slow. The 5 GHZ frequency devices do not have this issue.

Is there anything that can be done to make the 2.4GHZ frequenct more reliable or is there changes to the setup I need to do?

thanks
