To resolve possible errors resulting from a software update, try the following steps:

1. Reboot the internet modem and router: Resetting the modem and router can help resolve network errors by restoring default settings.


2. Check if the problem is within your control: Ensure that the modem and router are correctly connected to each other and to the service line, that any coaxial cables are firmly connected, and that there is no visible damage to any wires.


3. Confirm the credentials of the internet connection: Verify that the username and password associated with the service are correctly entered into the modem or router configuration page.


4. Disable any security software on the computer: Some anti-virus and security programs can interfere with the network and can cause connection issues. Temporarily disabling the program can help isolate the problem.


5. Check for connection issues from the service provider: Depending on the service, there may be scheduled maintenance or outages that can cause temporary connection problems.


6. Check the available IP addresses: Ensure that the IP address assigned to the computer is within the IP range of the modem/router. If the IP address is beyond the range, reset the modem/router and re-configure its settings.


7. Connect the computer directly to the modem: Disconnect the computer from the router and connect it directly to the modem to test if the router is the source of the issue.
