Your machine is an HP 15-r018dx, its specs

             https://support.hp.com/au-en/document/c04262932

It has

Network Card	10/100BASE-T Ethernet LAN (RJ-45 connector)
Wireless Connectivity	1x1 802.11b/g/n WLAN

Both are very slow in comparison with today standard. CAT 6 is better Cat 5e but for your machine, it doesn't matter anyway because it NIC is very slow.

Your machine was built around 2014 therefore the chance to upgrade wifi adapter is very slim to none. You can use USB options

1. Wifi: You can use an adapter which is similar to the following device

 2. NIC: You can use an adapter which is similar to the following device, you will get 2 more USB ports
