@paulnet 

We are almost in the same boat idk why 

i could get easily my full speed through isp wifi 5 router but in my deco xe75 pro wifi 6 i could NOT 

very frus

  @DrAhmed86 - ive got a new a Wifi 6E card for the laptop arriving tomorrow - will report back if it makes any difference - I doubt it. 

  @paulnet 

ur doubts may come true lol

cause ive tested with my pixel 7pro connected to 6hz and still the same issue unfortunately 

  @paulnet 

You can see from my performance tests below that there does indeed seem to be a slight limitation with the backhaul but was surprised to see that the iPhone 16 Pro (Wi-Fi6E) was much better performing but I put that down to iPhone 16 Pro having the latest Wi-Fi chipset and that was the only device on the 6Ghz band using the 160Mhz channel.  It looks like my Win 11 Laptop (Wi-Fi6) doesn't perform too badly on the primary XE75 but struggles a bit on the satellite XE75 but still getting 500Mbps plus download speed based on recent testing, which I'm pretty happy about.  I guess because Win 11 Laptop is old and not using the latest Wi-Fi chipset and don't forget more Wi-Fi users on 5Ghz band?  

Don't forget there is a big overhead when using Wi-Fi and expect to only get 70-80% throughput on connected Tx/Rx rates depending on whether using 80Mhz or 160Mhz channel?  Also, TCP can be an overhead as well as UDP testing is much better?

Note - My satellite XE75 is on a different floor to the primary XE75 and have 40 devices on 2.4Ghz & 5Ghz bands.

Performance results over the last 6 months:

(80MHz channel) - Win11 Laptop Rx/Tx rate 1200Mbps, so max expected throughput 840Mbps

Tool                (Primary XE75 D/U)       (Satellite XE75 D/U)    

iPerf3(TCP)    520Mbps/400Mbps        311Mbps/238Mbps         Using Win 11 Laptop

iPerf3(UDP)    948Mbps/600Mbps        920Mbps/669Mbps        Using Win 11 Laptop

Note - Upgraded XE75s and IoT devices using their own SSID.

iPerf3(TCP)    630Mbps/473Mbps                                                30/09/24 Using Win 11 Laptop
iPerf3(TCP)    682Mbps/652Mbps                                                03/10/24 Using Win 11 Laptop
iPerf3(TCP)    643Mbps/591Mbps        561Mbps/472Mbps         23/10/24 Using Win 11 Laptop

(160MHz channel) - Win11 Laptop Rx/Tx rate 2400Mbps, so max expected throughput 1680Mbps

iPerf3(TCP)    714Mbps/716Mbps        320Mbps/264Mbps          Using Win 11 Laptop

iPerf3(TCP)    803Mbps/740Mbps                                                 01/10/24 Using Win 11 Laptop

(160MHz channel) - iPhone 16 pro Rx/Tx rate 2400Mbps, so max expected throughput 1680Mbps

Tool                 (Primary XE75 D/U)       (Satellite XE75 D/U)

iPerf3(TCP)    953Mbps/800Mbps        783Mbps/537Mbps          04/10/24 Using iPhone 16 Pro

Note - 1Gig switch was probably limiting iPhone 16 Pro download speed as have seen approx. 1500Mbps performance figures on this forum for Wi-Fi6E using the 160Mhz channel.

Hi David, 

The wireless link speed from the laptop is 1201 Mbps(on the main and also on the second Deco)

Yes we have dynamic IP Addresses on Voneus Fibre

I have received your email. 

Thanks

Paul. 

 @David-TP 

Hi David, 

For your information.   I have just tried the connection with my laptop with a TPLink Wifi 6E USB Adaptor connected to the main DECO unit.  The link speed is 2401 Mbps and there is no difference to the upload / dowload speeds to the main or second DECO units. 

Thanks

Paul.
