How do I know speed of wireless adapter?
« on: July 05, 2019, 09:01:56 AM »
Hello,
I have an ad-hoc network this way

the main PC has a built-in wireless adapter ("ac" grade) with both: 1) hosting ad-hoc network 2) connection to internet (unrelated to ad-hoc)
and the second PC has: 1) a built-in wireless adapter connected to Internet 2) and an external wireless adapter (claiming 300Mbps N network speed)

I've connected the 2 PCs with input Director, which has file sharing functionality. the speed of files sharing is around 4-5MB/s

5MB/s is no where 300Mbps claimed for the dedicated adapter, and no where close to the 'ac' built-in adapter (in the main PC)

how do I know the (standalone only) speed of both these adapters? (meaning: what is the full speed of each of these adapters?)

--

if the 300Mbps adapter is the bottleneck, I know to maybe look for a better one
if the ac adapter is the bottleneck, I know I would need to buy another (external) adapter
(I need to know what are my actual hardware speeds to know what to do)
Execuse me for the long post...!

4-5 MB/s = 32 - 40 Mb/s

That's a little low, but you will never get 300 Mb/s = 37.5 MB/s out of that adapter, see https://www.dslreports.com/forum/r32434290- - there's just too many things going on with wireless networking and that "300 Mb/s" is a marketing number.

Sure, you will get faster if you use an ac adapter in the second PC, particularly one that uses the 5 GHz band.  But even then, don't expect what the numbers tell you...AC1200 will not get you 1200 Mb/s.

I highly recommend this article in unpacking the marketing numbers of wifi equipment -- https://arstechnica.com/information-technology/2017/03/802-eleventy-what-a-deep-dive-into-why-wi-fi-kind-of-sucks/

Otherwise, there's nothing like the PITP* protocol...
