I have an hp Pavilion deskdtop Model m9077c, Intel Core 2 Quad Q6600 processor, upgraded from Vista to Windows 7 X64 Home Premium (Ver. 6.1.7601).
My Internet connection is via at&t Uverse and a 2Wire gateway.
-Recently I downloaded what turned out to be a bogus software (which I have since deleted) and it resulted in a yellow triangle showing up on my wifi icon in the tray, telling me there was no Internet connection. The connection to the router and my home group is fine with strong signal. I also have multiple other desktops, laptops, iDevices and even an EV charger that are connected to the internet throught the same gateway without any problems. Simultaneously, I started to get warning messages from my McAfee that my Real-Time Scanning was turned off. Turning it on manually proved to be ineffective as it would turn off again within seconds everytime.
- Windows Network and Sharing Center shows that my connection to the router is OK, but there is no Internet connection. So I ran Windows Network Diagnostics and the response was: "Issues found, security and firewall settings might be blocking the connection."
- I contacted at&t and they managed to ping and reset my router remotely. In the end, all they could tell me was that the problem was in my computer's setup and that I should get help from Windows or McAfee.
- A suggestion from a McAfee support forum was to uninstall McAfee, restart in Safe mode (which would allow Internet connection), download and reinstall McAfee, and do a full scan to remove any potential virus.
Unfortunately, I did not have Internet connection even in Safe mode! So now the problem still persists and I do not have McAfee on my computer either.
Any suggestions/solutions would be greatly appreciated.
