Hi,
 
I'm currently on Spectrum 940Mbps . I'm getting the full 940Mbps download speed when my laptop is wired directly to the LAN port, but only get about ~600Mbps over 5Ghz wifi despite the laptop being less than 1 foot away from the Archer C5400. Is this normal?
 
Thanks,
Pasquinel

A further look into your link mentioned the following:

 

Two end point devices negotiate the maximum link speed between them based on their individual ceiling speed and the link quality. While for 802.11 wireless, the nature of being prone to interferences combined with various overheads means that the actual transmitting speed is normally 40-60 percent of the associated speed.

 

The wifi chip in my laptop is a Killer Wireless-AC 1550i which is a 2x2 so it only maxes out at 866.7Mbps.

 

So 866.7Mbps X 0.6 (best case scenario) = 520.02Mbps which sounds like it's in the right ballpark for what I'm seeing, so this looks like a non-issue and what I should be expecting.

With computer connected to the 2.4GHz, what is the speed you can get? 

 

Please click here to check the wireless negotiation speed with computer connected to the 5GHz. 

 

Try to customize the wireless settings of the 5GHz, like wireless channel and channel width. 

 

May it help and have a good day.

On 2.4Ghz, I get download speeds that average ~100Mbps.

 

I checked my wireless negotiation speed on the 5Ghz wifi connection from your link and it maxes out at 866.7Mbps, which unfortunately doesn't reach the 940Mbps supported by my Spectrum Gig internet plan. I tried adjusting the channel width from auto to 80Mhz and trying various other channels but the wireless negotation speed ramains 866.7Mbps. I suppose I can live with connecting directly over wired to get the full 940Mbps because the laptop is right next to the router, unless you have any further suggestions?

 

Thanks

Thanks for your clarification.

 

Yes, you are right, the wireless negotiation speed is not the actual speed, instead, the actual transmitting speed is normally 60% of the wireless negotiation speed.

 

Compared with them, the current speed is normal. 

 

If need any further help, please let us know.

 

Good day.
