Model: Adapter  
Hardware Version: V2
Firmware Version:

Hi,

 

I recently upgraded to 1000/100 Mbps, and unfortunately, I'm not getting that advertised "1.3 Gbps" over 5GHz WiFi.

 

The best I got was around 530 Mbps. Upload is fairly consistent at around 97 Mbps.

 

The router is FritzBox 6660.

 

Any tips, tricks, suggestions?

 

Thanks in advance.

Hello @p3r02d3r0 

 

The advertised 1.3 Gbps is the Link Speed or Negotiated speed on the physical layer, and actual 5Ghz Wi-Fi speed could be 40%-60% of the Link speed and also limited by speed comes from router.  How to check the associated/link speed on a wireless client

 

Archer T9UH adapter supports 802.11ac, and to get the 1.3Gbp= 3*433Mbps maximum Wi-Fi Link speed on 5Ghz, it needs to work at 3* MIMO & 80Mhz. 

From your router model spec, it seems Fritz box modem supports 2* MIMO, so at best you should get 2*433Mbps WiFi link speed on 5Ghz. 

 

  • If the link speed is 866Mbps, then your actual speed seems to be reasonable.
  • If Link speed does not reach 866Mbps, try to  adjust Router 5Ghz settings to 80Mhz and see if that helps improve 5Ghz link speed.

 

Hope this helps clear things up.

@Solla-topee thanks for replying. That makes sense.

 

Yes, the router has already been set to 5GHz/80MHz, and with the latest speedtest I'm getting 543.59 / 96.93. So, those speeds are reasonable?

 

Thanks

Hello @p3r02d3r0 

It sounds like the case i mentioned above. Please check if 5Ghz Wi-Fi link speed is around 866Mbps, if so 500+Mbps actual Wi-Fi speed/ speed test is reasonable

@Solla-topee Yep, seems like it.

 

 

Out of curiosity, is there a tweak to get more speed out of it? A repeater?

 

Thanks!
