If I make a lan cable on my 5GHz Wi-Fi amplifier and do that on my laptop, I get 1gbits right?
I don't know about it!
A WLAN only amplifies the WLAN signal. Just buy a Wi-Fi stick.
A repeater increases the range and does not amplify anything.
And no, you won't get a gigabit LAN at 5 GHz. Depending on which 5 GHz standard is available, half would actually be expected.
If you connect your router to your laptop via a LAN cable, you have a chance that your download rate will be better than if you only work via Wi-Fi. Nevertheless, I would not want to guarantee you a gig performance even with a Gbit contract.
There may still be performance restrictions, e.g. Due to Due to the performance of your laptop's network card, the length and lack of shielding of the LAN cable, or due to ongoing background processes (apps, firewalls, virus scanners).
From notebook to Wi-Fi amplifier it is 1Gbit, but then it continues with the WLAN speed. Pure 5GHz amplifier usually 433mbit.
Mine with strengthen, increase the range.
Doesn't bring you much, even if that were possible, since you hardly have a 1 gigabit internet connection.
It makes more sense as he said the lan cable to the repeater
Not necessarily. At the present time you would be right, especially since there are very few providers in Germany that offer the normal consumer a 1 Gbit / s line or above. However, these speeds are usually never reached.
However, if we assume that an effective speed of greater than 1 Gbit / s would be achieved at the home connection, then it would be possible to reach Gbit / s via Mu-Mimo with a repeater. To do this, however, the wireless connections would have to be set relatively optimally and there should be no interference.
If repeaters and routers would support 802.11ax and a Gbit / s line would be effectively there, then Gbit / s could definitely be used. But ultimately, as a normal consumer, it is currently rather unrealistic to achieve with WLAN Gbit / s speed.
