This article can help you troubleshoot Internet connection problems that are not dependent on your service provider.
It is necessary
(preferably) 2 devices using an internet connection (one over a wired connection, the other over a wireless)
Instructions
Step 1
Check the operation of the second device. If the Internet works on it, it means, most likely, the problem lies in a faulty cable or inoperative LAN / WAN port (less often - from incorrect settings). If you are using a wireless router as a Wi-Fi access point, try resetting its settings to factory defaults, having previously written down the current ones, and restoring them one by one - "by trial and error". It is also worth trying (if the hardware data allows) to connect the LAN cable to another port or replace it. Check if the pins of the WAN cables and ports are loose anywhere.
Step 2
If the Internet connection is also lost on the second device, disconnect the router from the network, disconnect the WAN / LAN cables, first disconnecting all devices from Wi-Fi (if a LAN connection is established, we do not disconnect from the local network). Wait a minute and plug in the cables and turn on the router. Wait for the end to turn on and reconnect to Wi-Fi.
Step 3
If the problem persists, turn off the router for a longer time (for example, overnight) and repeat the entire procedure (only with a longer delay before turning on). It is advisable to replace the LAN / WAN cables, and while the router is disconnected from the network, take the router to an authorized service center to replace the LAN / WAN ports.
Step 4
Is the problem still not fixed?
- Contact your Internet service provider and ask for help setting up your router correctly or explaining the reason for the disconnection of the Internet. Please note that, most likely, the specialist will require your data from the Agreement concluded with the supplier (most likely, only the account number will be required).
