Question

Internet connection

My computer suddenly lost Internet connection yesterday. It is still connected to the network (through ethernet, not wireless), but it can't access the internet. I have several roommates who are experiencing no issues with the internet, both through the wireless connection and ethernet. My computer is the only one having the issue. Can anyone help me fix this?

Not with that level of detail.

There are some causes for connection to the router but no internet such as expired antivirus and malware but here we have little to work with. Until you know more, reboot, test then forget this WiFi connection (varies with OS) then connect again.

I have checked my anti-virus software, disabled the firewalls, etc to see if that affects anythibg, with no results. Troubleshooting the network connection simply shows that the connection exists, but it still can't connect to the internet. It isn't an issue with a router or modem, since several other devices are having no issues.

I have attempted disabling, then re-enabling the network adapter in the Device Manager; uninstalling it, rebooting, and letting it reinstall; and checked for updates to the software. The only effect was that, for about 30 seconds after rebooting the computer, the connection display didn't show the "no connection" warning sign, but still could not connect.

Not really sure what else to do, at this point, since most of the information I've found while searching the Web is fairly outdated. What other information would I need to provide about the issue?

"it isn't"?

In reply to: Additional info

As I've seen this happen, how will you know unless you reboot the network gear and do the forget and rejoin?

Remember I'm a bit too seasoned on this area (wrote router code in the 90's) so if you declare it isn't that, then I may have to let you season (wait for you try harder.)

I noted forgetting this connection then adding it. You listed other methods which I hope didn't mess up the machine further.

As a test, go to another hotspot and re-test. If your machine works there, it's the network and not your machine that has the issue.

Let me clarify

In reply to: "it isn't"?

I do not use a wireless router. I use an ethernet connection with my apartment's internet. However, when this stopped working, I switched over to my roommate's wireless connection, which uses an entirely separate Internet provider from the apartment's provided connection (the ethernet connection is through Century Link, and their wireless is through Google Fiber). The issue was exactly the same. With both the ethernet and the wireless, only my computer has any issues. Every other PC, laptop, iPad, etc, connects fine with both connections.

I'll try the forgetting for the wireless connection, but I can't find any way to do that for the ethernet connection.

I went through the forgetting process for the wireless connection with no change. I also cannot get Internet from other wireless hotspots. Same issue where I can connect to the network but can't access Internet.

That's your lead.

(NT) Maybe Knoppix too ?

That's a good test.
