I have an Acer Aspire 5552 running Windows 7 64 Bit with 4GB of memory. I suddenly can no longer connect to the internet wired or wirelessly. IE won't display any pages and I can't even ping Google from a command prompt! I am able to see all available networks wirelessly and am having the same problems on multiple routers. Other computers are able to connect.

I have run scans using MalwareBytes and Super Antispyware. I have made sure that IPV4 and IPV6 are set to obtain an address and DNS server automatically. I ran a ipconfig /dnsflush command.

I don't know where else to go from here and would greatly appreciate any assistance!

Hi bbr0511
Please download Farbar Service Scanner and run it on the computer with the issue
Make sure the following options are checked:
  • Internet Services
  • Windows Firewall
  • System Restore
  • Security Center
  • Windows Update
Press "Scan".

It will create a log (FSS.txt) in the same directory the tool is run.
Please copy and paste the log to your reply.
Thank You -

Thank you for responding.

I ran the scan and got the message: Windows Resource Protection did not find any integrity violations.

Immediately after the scan completed and the previous message popped up, in the system tray, an icon opened up that looks like the one for Windows updates. It said that Windows was downloading some updates, but stuck at 0% and then went away. I tried connecting to the internet, but my results are the same. I also tried a reboot on the laptop, but there is no change.

Go back to the Command Prompt box (as last time)

If this is exactly the same as you have done, please try them again in case one was missed.

From the command prompt type the following in this order, pressing enter after each line :

ipconfig /flushdns

ipconfig /release

ipconfig /renew

netsh winsock reset

Next Please post a snapshot with Speccy -

This will help us check if your internet card is active -

Ok, still having the same problems after I ran the previous commands. I ran the Speccy program. I couldn't publish the results, because I obviously can't connect to the internet. I saved the results in a .txt document.

Looks like you have two firewalls running either one of these could be interfering with your connection:
Running AVG Firewall
Running ZoneAlarm Toolbar IswSvc


and RPC has been stopped:
Stopped Remote Procedure Call (RPC) Locator

Type services.msc in the start search box, right click on Remote Procedure Call (RPC) Locator, choose properties. In the dropdown box, set it to 'automatic' and start the service.
