Transfer speed to NAS over wifi funnies

Ev0 · 29 Oct 2018 at 20:54

Am trying out a new router at home, Draytek 2762ac to try and replace my EE provided router with an all in one device rather than going with separate stuff for mode, router, wifi.

Testing some file transfer speeds copying files to and from my NAS (QNAP TS-253A) and am getting some results I'm not expecting and am not sure what could be up.

Copying a file from the QNAP over the EE device wifi I get speeds to my desktop of around 35 to 40MB/s.

Copying the same file from the QNAP over the new Draytek I get speeds to my desktop of around 50 to 55MB/s, all good there.

But where it gets a bit funny is when copying something back to the QNAP.

Over the EE wifi connection the file goes at the same speed as the download, 35 to 40MB/s.

But over the Draytek the file transfer sits at around 20ish MB/s.

Any ideas why the Draytek is quicker pulling files, but under half the speed uploading them to the QNAP when the EE unit gives the same speed either way?

Something obvious I'm missing?

Draytek's are odd, I've never liked them.

Wi-Fi is a variable technology, factors such as file size, sources of interference from walls/objects including other Wi-fi networks/channel congestion chipset differences and the channel width used can all contribute, if you care about speed and consistency, use a cable.

Agreed. Even on high end kit data transfer will always be a bit wobbly on WiFi.

Urgh I know use a cable, use a cable, can't be done in this instance though

Just curious that's all as to why with every other variable the same, just the router being different, transfer speeds to the NAS are so different than receiving from it on the Draytek, when not on the EE unit.

The wireless performance on Drayteks has always been a bit naff when I'd tried them in the past, only tried this one out to see if it was any different and was pleasantly surprised when it seemed to be performing well.

Until I tried a file copy to the NAS
