I have a problem with my charging cable because my PC has a new video card and it runs smoothly and perfectly but the internet is not strong enough despite a very good router which also lets the PS4 play with the newest ones the black ob's could play i would yes like to put a Lankabel so that is better but my parents do not want to put that through this corridor is there an alternative?
An alternative to a LAN cable would be a PowerLAN device, but these are expensive and are not as good as LAN cables, but much better than WLAN
For PowerLAN, the Internet is running on the power cables in the house
Either you use a WLAN amplifier or a DLAN over the power line
With D-Lan / Powerline / Powerlan or as they are now called I have never had good experiences. But there are devices like these here:

These receive a W-Lan signal from the router and you can connect to the LAN port devices that have no Wi-Fi.
If you then use a Lan switch, you can easily connect multiple devices so.
