GL-AXT1800 Slate Slow 5Ghz Wifi Upload


I’ve been doing speed tests on the 5GHZ band and noticed that download is around 700 Mbps, but upload is a lot slower at around 200 Mbps. Is this a known issue?


No known issues.

Speed may relate to devices etc.

Can you confirm what is the speed if you test on cable?

Hi @alzhao,

Wired speed test is better, though not as good as I expected:

Slate (wired): 856 Mbps download / 518 Mbps upload
Mikrotik 4011: 881.4 Mbps download / 840.8 Mbps upload

The wired upload speed test on the Slate is better, but still slower than I’d expect. Tests were run on a M1 Mac Mini with latest MacOS. Slate has the latest stable release (4.0.2).

I ran this test with the latest beta software (Linux version 4.4.60 (glinet@glinet) (gcc version 5.5.0 (OpenWrt GCC 5.5.0 r16399+157-c67509efd7) ) #0 SMP PREEMPT Wed Aug 31 08:18:38 2022) and its fixed the upload:

Slate (wired): 812 Mbps download / 860 Mbps upload (

I’m now seeing about half speed (worst) on uploads vs download on 5Ghz.
