To help isolate a problem with accessing the internet first try using a wired Ethernet connection directly into your modem (and reboot your modem).
- If the problem continues, then the issue is with your internet provider or possibly your modem.
If the connection is fine while connecting directly to your modem
- Try connecting to your root Wi-Fi point with an Ethernet cable.
- If the problem continues then it is a problem with your root Wi-Fi point
- If not, the problem is an issue with the wireless connection.
