Not sure which Category this falls in but it's a general question about differences between 2.4Ghz and 5Ghz.
The obvious things like: higher frequency, less wall penetration, higher bandwidth, etc. of course I know them and for those who don't can look it up on the internet so i don't need to get an answer what's repeated all over the internet already anyway. I'm looking for more depth insight in practical differences.
Both can do 100Mbps easily, so shouldn't be a bottleneck for anything under 20Mpbs I suppose.
Still, here is my setup:
Going from south east Asia over VPN to Europe.
using speedtest.net to Dutch providers.
The internet itself supports (checked with local servers over speedtest) speeds over 40Mbps
I also tested local LAN for 2.4ghz and 5Ghz both easily break the 100Mbps barrier.
So you'd expect the bottleneck be somehow the VPN connection from Asia to Europe and thus there shouldn't be a significant change in speed by choosing either 2.4 or 5 Ghz, right?
Yet I did some testing and found out there are differences, between the testing I kept changing
the 2.4Ghz and 5Ghz to be sure I wasn't doing them all in 1 row (to minimize any effects of
differences between the time the tests were done):
It clearly shows in the upload speed the differences are below anything to break my head over.
But between the download there is a clear difference in speed.
Again, the tunnel to European Server is the same throughout the test. the only thing that varies
is the WLAN frequency.
(yes of course I made sure I was the only one on the WLAN)
How can it be, that both wireless network I can copy locally well over 100Mbps so shouldn't be a bottleneck,
there is still such a huge difference to Europe?
I'm sure there are much more technical detailed differences then just bandwidth and frequencies that have a reason for this. i was thinking, maybe the 5Ghz network changes something in packets which VPN might prefer? As I do know VPN over wireless isn't something VPN likes.
Also I know high ping is a killer for VPN, but the PING is roughly identical as well.
So, anyone with an explanation?
and please no:"no difference, just your ISP" I did this test to find out numbers for something I noticed already
since I moved here. Since I moved it "felt" like 5Ghz was faster then 2.4Ghz but kept waving it off myself as: BS, both 2.4Ghz and 5Ghz can easily do 10 or even 20Mbps so that can't be it.
But it kept nagging me, so that's why I did these tests to get numbers and behold...
Explain it to me please?
ADD: I did write the numbers nice and clean ordered properly in the edit field. But somehow when I click post, save edit, etc it totally screws up the arrangement so I uploaded a screenshot
