I have a 500 MBit/s connection from UPC. With this, I first go via cable to a Netgear WNDR4000 "Gigabit Router". Then I have the TP-Link as an extension on the lower floor of my house. The TP-Link is "fed" by the Netgear wireless 2.4 GHz. - I use a strong Dell desktop and a higher-end Lenovo laptop, both with Windows 10.

From Netgear router with cable:

- With my desktop I can get 520 download / 51 upload (shit) at the moment, which is what UPC promises.
- With my laptop I get 380 / 51.

From the Netgear router wireless to the laptop, measured next to the Netgear (display: full signal strength):

- On the 2.4 GHz band there is 62 / 51, on the 5 GHz band 120 / 51.

From the TP-Link wireless to the laptop, measured next to the TP_Link (display: full signal strength):

- 20 / 20 MBit/s

So it's obviously quite a lottery with the achievable speeds. Maybe it's not only related to the devices and their drivers, but also to the settings of the firewall and antivirus programmes.

I would probably have better speeds if I didn't use the Netgear and connected directly to the UPC modem. But I like to have another barrier to the internet.

To be honest, the 20 MBit/s are enough for normal use anyway. For example, I can watch the daily news in HD on the SRF website without jerks. So I don't really notice the slow speed. Only when you want to move large amounts of data around is it a bit cramped.
