I've been using a Western Digital My Book World Edition NAS with two 1.8TB HDD disks for a couple of years which I describe with RAID1 - Mirroriong.
The NAS is connected to the wireless router via Ethernet,
my laptop secures its data via Wi-Fi on the NAS once a week
now and then I play videos from the NAS on the laptop / TV.
I have always wondered about the slow transfer rate.
If I write a large files on the NAS that runs with max. 3MB / s, from the NAS to the laptop that runs with max. 1MB / s. If several copies are executed in parallel, the transfer rate is divided by the number of copies → Performance breaks.
Can someone tell me where the bottleneck can lie here? WIRELESS INTERNET ACCESS? WLAN router? NAS? Or hard drives?

Disable Wlan, replace it with a LAN connection (cable) and the problems no longer arise.
Wi-Fi is no guarantee for high transfer rates because it is prone to failure and often works with poor connection quality
Thank you, silver fan,
ie but if I want to stay mobile with my laptop in the apartment, I have to accept the slow speed and new router or new NAS bring no improvement.
Correctly.
The silver fan is right. WLAN is a great technology when it comes to mobility, but in almost all cases it is subject to net bandwidth and robustness.
You can optimize the WLAN, of course. Repeaters provide extended illumination, but reduce throughput and latency again. In my hut are 4 WLAN access points via LAN on the net. With 802.11ac I get enough signal strength everywhere so that the girls can watch TV everywhere.
However, I still use a LAN cable for large file transfers and backups. I'm just a traditionalist ;-)
What else you can do: More RAM in the NAS increases performance. The change from 4 to 16G has brought a lot, especially with parallel transfers, because the plates are better cached. The use of multiple LAN ports - if available - as a link aggregation help many users.
