    "Limited access" WiFi connectivity after virus removal, registry edit.


    I'm trying to fix my girlfriend's Windows 7 laptop after she had a virus/malware infection. I'm pretty sure we've successfully cleared the virus (an updated/full scan with Malwarebyte's Anti-Malware in safe mode comes up clean). However, we have had no Internet access since the infection. The wireless router/connection itself is fine (I connect to it daily with my laptop, as I am to write this post) but her laptop won't connect to it, we can't browse any web pages.

    I may have made the problem worse in trying to resolve it. I stupidly followed the advice on a forum for some registry edits for Windows XP--deleting WinSock and WinSock2 from the registry and then restarting the computer in hopes they'd re-register themselves. Unfortunately, WinSock2 re-appeared but WinSock did not. I'm wondering if this has created a new problem (or compounded the problems we were already having).

    In diagnostics, we currently get the following report: "Wireless Network Connection doesn't have a valid IP configuration." I just ran an ipconfig in the command prompt and got the following results:

    She no longer has/can't find her original Windows install disc. So with that in mind, any ideas for troubleshooting/resolving this? We'd both really appreciate it.

    I hope not. :)


    You could try a system restore to a point before you edited the registry, which should at least restore the registry.

    As your partner doesn't have a Windows 7 DVD you can create a repair disc, which you can then boot from to get into the recovery environment where you'll have several options to choose from.

    System Repair Disc - Create

    You could also go into the Network & Sharing Center, click Change Adapter Settings then right-click the wireless adapter and choose Diagnose.

    you can also try during boot up press F8 and select last known good configuration.

    Cheers !!

    Sorry, haven't had much time to troubleshoot/respond back. We finally, after some trial and error with other solutions, used system restore to go back to a restore point. It solved the problem. I appreciate the suggestions/help, thank you.
