  1. Hi there, I'm new to this site and not very technically minded.

    This may not be the right place to post this, so sorry if its not.

    I have a Sony vaio with windows vista. I am currently with virgin.

    I can get onto the wifi with my phone and ipad no problem but I can only get the wire connected Internet on my laptop. I have previously been able to get onto wifi on the laptop though.

    Any suggestions what I need to do so I can get the wifi back?

    Thanks in advanced

    *login as an admin
    *get a command prompt; click start->search and enter CMD & hit enter

    now type these one at a time:
    • ipconfig /flushdns
      nbtstat -R
      netsh int reset all
      netsh int ip reset
      netsh winsock reset
    reboot and attempt wifi connection

    Hey, unfortunately this hasn't worked?

    Any other suggestions.

    It says it has an excellent signal strength, limited connectivity, unidentified network?

    hmm; is there a wired connection at the same time - - disconnect it if so and try again.

    No, no wire connection.

    * first verify that the driver is correct
    Control->Admin Tools->Computer Mgmt->Device Manager
    [+] expand Network Adaptors
    there should not be any Yellow marks and your WiFi device
    right-click->Properties should show Device is working Properly

    * next check that the device is ENABLED and active
    (on a Dell, the Fn+F2 toggles the wifi on & off - - check your Sony vaio Users Guide

    * launch Control -> Network & Sharing Center
    on the left, click Manage wireless networks
    for every network shown; right-click->remove.

    *Reboot and look for your router
    a) can you see it at all?
    b) does it attempt to connect?
    c) succeed or failure?

    Ok, let's look for some details.

    Which Windows is this {XP,Vista,Win/7,Win/8} Home/Pro/Ultimate ?

    get connected as best you can and then

    get a command prompt and type into it
    • route print >myRoutes.txt
    then open myRoutes.txt, copy all the contents and paste that into your follow-up

    Please describe your symptom with some details - - are you failing with ALL application (your email application and your browser access to ALL sites) or just one or two specific sites?

    If you can
    and yet fail when accessing

    then we have a browser issue and the TCP setup is fine.
