Slow wifi for internal resources but fast on internet with Deco E4
Hi
I have this strange issue with my wifi. If I access my local NAS from wifi either with SMB or FTP I get slow speed (it varies between 10 Mbit/s to 25 Mbit/s). However if i download from internet (HTTP, HTTPS, FTP) I get speed around 80-90 Mbit/s from the same laptop sitting at the same place and testing right after the internal test. Speedtest.net shows 94,36 down and 94,80 up.
The NAS is cabled on a gigabit switch. If I connect my laptop with cable directly to the gigabit switch I get speeds around 900 Mbit/s when downloading from the NAS so both the laptop and NAS are performing fine.
If I connect my laptop to the main Deco with cable I get 85-90 Mbit/s when downloading from my NAS. I am aware that the Deco E4 is capped at 100 Mbit/s on the ethernet port so that is good speed.
I don't understand why accessing my NAS is so slow on wifi when accessing internet is much faster. I expect that I can access my internal NAS with the same speed as accessing internet. I have even tested with the same protocol (FTP).
Hope I can get some help here to solve my issue.
Thank you
