Netgear GS605-400PES 5-Port Gigabit Ethernet Switch

What to do if WLAN is not the data throughput is achieved the expected / needed? Man / woman dodges on cable.
Although we should have sufficient data throughput on our router in the 5GHz band, the result was disappointing.
2. A network cable came to move behind the skirting board for reasons of space out of the question, so I needed a switch.
Data throughput has improved significantly as expected,
When streaming cache is now stable at 99% and there is no longer between buffers instead.
Currently 3 ports are occupied. 1x switch - router, 2 x PC. Thus a total of 4 LEDs light up, 3x + 1x Port Power.
As with many switches in this price range can / must not be configured, just plug in and that's it.
