I have a problem with the TP LINK deco M4 on a 1gbp plan for Wifi

See tests:

• HUB4 (Modem Mode) > Laptop (Ethernet) 900mb download speed
• HUB4 (Modem Mode) > Deco > Laptop (Ethernet) 900mb download speed
• HUB4 (Modem Mode) > Deco > Laptop (Wifi 5ghz) 300mb download speed

I then tried reverting HUB4 in router mode and disabling the deco.

• HUB4 (Router Mode) > Laptop (Ethernet) 900mb download speed
• HUB4 (Router Mode) > Laptop (5ghz Wifi) 300mb download speed

On the hub 3 i was getting 350mb on a 350mb plan, so cant figure out my deco is not providing this on laptop via wifi.

Laptop specs:

The wifi is ac and is capable of handling up to 900mb
These devices all received sub 300mb download speeds

• Dell XPS
• Samsung 20 Ultra
• Samsung s10+ 
  
  Any advice on improving wifi speed on deco?

Update post fitting attenuator : Still no improvement on speeds on device

300Mb by wifi is good.

OK I just retested

The Ethernet speed on the HUB 4 is 800mb but the Ethernet speed from the deco M4 is 250mb
Wifi is also 250mb on main node
