Slow SMB Speeds over WiFi
Hello, I need some help optimizing SMB speed when connected to Wifi. I don’t have any problems over Ethernet. Speeds: File transfer from NAS to windows laptop over ethernet 115 MB/s File transfer from NAS to windows laptop over Wifi 15-25 MB/s File transfer from NAS to Android phone with SMB2 60 MB/s File transfer from NAS to Android phone with SMB3 35 MB/s (why slower than SMB2?) Internet speed test with Wifi on laptop 135 MB/s (1g from ISP) File transfers were done with 10GB 4k BD Rip ...
I should be able to go faster over Wifi since my router (Asus AX86u) has been tested to go 600 MB/s on the 5g band, obviously I don’t expect that real world but it should at least beat 1g ethernet. Speeds don’t change much whether I’m writing or reading to the NAS, so I’m pretty sure it’s a networking or SMB issue. Settings: MTU 1500 IPv4 DHCP SMB Multichannel on (I tried it off as well no noticeable difference) Compression level ZLE
