Lan-Kabel verlangsamt drahtlose Verbindung?

ByChangeTime06

Hallo, bei mir und meiner Mutter ist vor kurzem ein Kumpel von mir eingezogen und er hat seinen PC mit einem Lan-Kabel mit unserem Router verbunden, seit dem ist das Wlan schlechter und das Internet langsamer (manchmal so schlecht, dass man nichtmal eine Website öffnen kann). Kann das zusammenhängen oder ist das zufall? vielen Dank…

No.

All “public” services have either been integrated or replaced on the Internet.

Of course, there are networks that are not public and are not directly connected to the Internet. This would primarily be the data connections of the power grids. There is no access to the Internet or from the Internet. This has security reasons. In addition to vital infrastructure, there are also, of course, military data communication that must not be linked to the Internet.

Most of these networks use normal Internet or Network technology. Just because the hardware is proven and is cheap.

The ISS uses a NASA’s own data transmission system. Although it has intrenet access and email addresses, it is then tunneled through the NASA network. Thus, ping times of more than 1000 ms are obtained. Just because this data network is very slow and inflexible.

This is the “Starship” completely different, using Starlink, which is based on Internet technology and is also directly connected to the Internet. In the “Starship” the astronauts could then have Internet with reasonable ping, so also video conferencing and even use simple multiplayer games. The last launch of the starship delivered many great, high-resolution video streams in real time. With the Internet capacity of the ISS, the transmission time of this data quantity would have taken at least 8 months.

So no, there is no competition, there are only systems that do not hang on the Internet (may) and they are built up to a few exceptions with the same technique.

No. The WWW is the most buntest and well-known part of the Internet. In addition, there are, of course, purely professional networks within the Internet as well as the Darknet and the Deepnet. A fairly old part is that Usenet, not to be confused with a Dutch, rather insane service of the same name and content relation to parts of the real usenet. Only older FidoNet.

There are different IP protocols and corresponding parts of the Internet outside WWW:

The most similar was Gopher, one called the totality of all Gopher servers the Gopherspace, the URLs did not begin with http://ec.europa.eu but gopher:// . This is extinct.

Furthermore, there are FTP and related protocols that begin URLs with ftp://Sftp:// e.g., this is also an alternative to WWW to provide content on servers – although not so comfortable and interactive.

In order to log into foreign servers and to work as command-line-orientated, usually under Linux or UNIX, there is ssh (formerly telnet).

A part of the Internet, which is significantly older than WWW, is the Usenet, the URLs begin with news: the protocol behind it is called NNTP. It still exists.

Also the email traffic, the SMTP protocol (or now a newer one), and the totality of all mail servers (MTA, mail transmission agent) is part of the Internet. The URLs start with mailto:

Whether you can also include WhatsApp here is a question of philosophers, I leave it open. The many social media are all part of WWW and not separate networks.

The gate network is still there. In addition, a variety of intranets.
