  1. Hey man! Whats up?
    I have router D-link dir-100 (cable). For about two days ago it blocks my internet connection. When i inpluged the cable and connect it direct from modem to my PC its OK but when i try to connect thru my router its imposible. I tryed to fix the problem rebooting the router or by changing some parameters but i still dont have internet. Please tell me how to fix the problem.
    Thanks a lot.

      The best thing to do in this case is to reset the router back to factory defaults. Use a bobby pin to push the reset button on the back of the router. After its reset, physically connect to it and go through the setup. If that doesn’t fix it, toss it and go get a newer model.

  2. I received a Kindle for Xmas. The only Wi Fi signal I get at home is Castle. I need to know how to suscribe and what the fees are. Hope you can help.

  3. I’ve had my Wi-Fi hacked–I’ve password-protected it twice now. What steps can I take to protect it even further so it is less likeley to be hacked again? So far, we are:

    1. Using WPA2 encryption
    2. using long passwords using numbers, letters and special characters

    Should I buy a new router? Our Wi-Fi antennae is strong–I live in a 3-flat building–we have 1 main PC on the first floor, along w/the antennae and a laptop on the 2nd floor. We are surrounded by apartment buildings.

    We recently discovered one of the hackers sitting by a window–we know, because when we powered off the Wi-Fi, she would pull her hair–we’ve decided to shut down the wi-fi when we’re not using it in the interim. Any help would be appreciated.

    Thank you

  7. Thanks for your U-tube video on the wndr3700. Super clear and clean. Love the no music, lack of wavy camera shots, and coherent presentation. Wish all were like that.
    Tried to leave a nice comment and + but G+ makes me leave my name (!) so came here to compliment you.
