I know this topic exists a thousand times but I can't get it to work. When transferring from my Windows PC via LAN i get around 105 mb/s but via wifi only around 30mb/s (Macbook or Smartphone (wifi5) - it's never more than 30 mb/s) 

 

My NAS goes directly into my router (1 Gbit/s LAN Port). Also the same low speeds for small and for big files.

 

I have read so many threads and forums by now...

These are my changes:

 

Settings -> SMB ->  SMB Extra configuration :

server min protocol = SMB3_11
aio read size = 4096
aio write size = 4096
strict locking = No
use sendfile = No
server multi channel support = Yes
write cache size = 2097152
min receivefile size = 16384
getwd cache = true
socket options = TCP_NODELAY IPTOS_THROUGHPUT SO_RCVBUF=131072 SO_SNDBUF=131072

 

 

 

And also here here:

Flash device settings -> syslinux config -> global:
 

net.ipv4.tcp_congestion_control=bbr
net.core.default_qdisk=fq

 

What else can I do to improve my wifi speeds? I mean if I download from the internet I can get speeds up to 60-80 mb/s via wifi. Why isn't that possible in my intranet?

EDIT: Seems like this is only happening to WIFI but I wonder why the hell can I download file from the Internet with 80 mb/s via wifi but my home network is only 30 mb/s via wifi and smb?
