The first thing I do when I have computer or equipment problem is reboot. Rebooting clears out your memory and gives your equipment a fresh start. Rebooting is not just for your PC, your printer and network equipment can use a reboot too. If you are having trouble connecting to the internet or you suspect your internet speed is slow, reboot your network.
Rebooting your network equipment should be done in a specific sequence. First power down your network modem and wifi router (if you have a separate wifi router.) If you have telephone service through your cable company, there will be a battery in your cable modem, this battery should be removed to ensure a clean reboot. Then power up your modem and wait until most of the lights stop blinking. Then power up the wifi router if you have one and again wait a few minutes. Finally power up you PC and see if your problem is been resolved.
If your problem persists, you can call your internet provider or contact me at suncitygeek@gmail.com
