Hello, are you already using the WLAN with other devices? If so, plug in the stick, restart the PC, then insert the installation CD again and run it through. Then try to establish a WLAN connection to the router as usual. To do this, you need to know its name and password (this is usually written under the router).
That's exactly what the part is made for, yes. It may be advisable to add a short extension for better reception. I always use this one: Delock USB 2.0 (A - A, 0.50m, 2.0)
The cable has an integrated wire and can be shaped as you need it and then stays in that position.
The part is quite good. At some point, I just didn't want any more cables. https://imgur.com/a/muLsRLR Here, once a speed test is carried out, only 1/4 of the power arrives. Besides, we have usb 3.0 today and the plug gets endlessly hot, so internet failures may be due to the overheated plug. But otherwise this is a fine solution.
According to the website linked here:
SYSTEM REQUIREMENTS
Computer with Windows or Mac OS®
Compatible with USB1.1/USB2.0
Microsoft® Windows 7, 8, 10: (32/64-bit)
Mac OS® 10.9~10.13
these sticks usually get relatively warm
the head pressure should actually be something else, light should be much more aggressive than a wifi signal...
