Mikrotik WLAN & CAPsMAN - Bad download perfomance
Posted: Thu Feb 21, 2019 9:50 pm
The problem is - and I don't really have any idea what causes it - wireless speed is cut roughly by HALF from what it is supposed to be.
The picture is:
NAS -gigabit> Mikrotik CSS326 -gigabit+PoE> wAP AC -wireless conn 802.11ac 2x2> PC with realtek 8822BE wireless module.
RB3011 is connected to CSS326.
The issue itself? For example, I'm trying to download from NAS a movie - a whole videofile, MKV packed, 30GB size. But instead of 60 MB/s, I have only 30MB/s. And I really don't know what causing the issue - and that drives me mad. Moreover, connection itself is super-stable - it just looks like something caps it at 30-40MB/s.
Next things I've tried:
1) Wired connection gives me ~900 Mbps. So switch is out of question, as well as maybe RB3011.
2) wAPs powered by PoE - cable cat 5e, 8 wires/4pairs. Everything is in working condition.
3) Aside of 8822BE, I've tried killer chipset and Intel AC-9560 - all the same, it just stucks at 25-40 MB/s.
4) Also tried making simulatenous workload for wAP, by downloading the same file on two devices (Killer and Realtek, Intel and Realtek) - speed just divided by half, giving 15-16 MB/s for each device.
5) Local storages are non-issue here - NAS works with two SATAIII HDDs, united in RAID0. Both client devices have NVMe drives with 3GB/s sequential write.
6) As well as it's non computing issue - NAS CPU is barely loaded, not even mentioning the PC's.
All in all, here's the screenshot - I guess, it would help to make thing even more clear, than I could writing all the stuff down....
And here's my expectations, or should I say, just "wish" - Intel 9560 + UBNT AC-SHD
