Why - if one has one's computer hard wired into broadband, does one find on occasion that settings? may be changed where you canNOT go on line - but one can use wireless ??
KCL what OS are you running? Are you logging into the machine as an admin?
While on the wired connection, right click the network icon in the System Tray. Then click Troubleshoot problems.
See what Windows finds.
I was impressed at the long list of troubleshooters included in Windows 10 and while they don't always come up with a solution they have often helped me to see what I should try by naming what is not working.
KCL First disable wifi on the computer then reboot. Recheck for your issue reappearing. If things do not change you can do the following as well:
Try the following steps and check if it helps:1. Click on start and type in cmd in the search box.2. Right click on the command prompt shortcut and select “Run as administrator”.3. Enter these commands one at a time in the command prompt and press enter.
If the issue is not fixed then try disabling IPV6, follow the steps below to do the same;
1. Right click the Network Connection icon in the Notification Area > Open Network and Sharing Center2. On the left hand pane, click "Change Adapter Settings"3. Right click on your Network connection in question (should be called Local Area Connection if hard-wired) > Properties4. Uncheck the box under "The Connection Uses the following items:" that says Internet Protocol Version 6.5. Click OK.6. Repeat for any additional Network connections that are exhibiting the same symptoms.
