    Hi,

    I recently experienced a problem connecting to the internet with my Toshiba A-215 S7413 Laptop. I am able to see the wireless signals that are available but when I try to connect to the one I usually use it says "windows was unable to connect to dlink". I never did anything out of the ordinary, it just stopped connecting for some reason.

    I have tried connecting to the same wireless with my other laptops and they do it without any problems at all. Are there any solutions to this problem or do I just need to buy another wireless adapter ? I provided a few screenshots 1 is the device manager and the 2nd one is for the ipconfig/all.

    I have exhausted all search on this fix and I really hope you guys can help me through this.

    Thanks

    Disable encryption on the router and try to connect that way,. If successful you can probably re-enable encryption and reconnect.

    If you cannot connect to an unsecured network try ...
