I made this guide if you experience problems such as a slow internet connection or inappropriate bandwidth where the current internet connection uses a router (which is generally used with other devices around at the same time). So it is expected to get maximum results by using only 1 device as a comparison with a router.

Please also make sure that the transmission media from the ISP (Internet Service Provider) is an RJ45 ethernet cable to connect with a PC/laptop device. The topology used in the guide is as follows, and can be adjusted to the conditions in the location:

ISP <–> wall jack <==> router become to ISP <–> wall jack <==> PC/laptop

<–> = transmission media

<==> = cable ethernet RJ45

1. Disconnect the ethernet cable connected to the router and connect it on a PC/laptop. On a PC/laptop, make sure the Ethernet status is Enabled and not a cross, the LAN indicator will turn into an exclamation mark (as shown in the image above), if you still get a cross, you must check the LAN cable and the connected device again.
2. On the Control Panel, select Network Connections.

3. Choose New Connection Wizard.

4. Click Next and select Connect to the Internet – Set up my connection manually – Connect using a broadband connection that requires a user name and password and in ISP Name you can set it with the ISP name and then Next.

5. Fill in the username and password provided by the ISP, then click Next.

6. Check Add a shortcut to this connection to my desktop to make it easier to click from Desktop and then Finish.

7. A pop up will appear as follows (if the User name and Password have been filled in), you can immediately click Connect and if successful, a connected status will appear.

Until this step, we can immediately try the speedtest to make sure the bandwidth is appropriate.

8. To disconnect, right-click the LAN icon and select Disconnect.

If you are still experiencing slowdowns or inappropriate bandwidth, please contact  the relevant ISP. Good luck and a great day.
