I have comcast.. and heres the Situation.. A few days ago i started having network issues (Router).. Basically my Wireless Cards could never Identify a Network, while my Direct Line (My PC) Did just fine.. Well I went to work/sleep Who knows.. And Came back and My Router had completely stopped working.. I was still able to Connect with my PC With a Cable directly to the Modem.. But the 2 Laptops with Wireless cards, could never Connect Via Cable .. because of DNS Issues. (Even to the Modem) Well basically.. I went though my Router and Checked all Settings, Access list, DNS Settings.. Everything was fine. So i tried the usual.. Power Down Each... Power Down Router with Modem on to Try to connect.. nothing... I even did a /ipconfig renew though my cmd in hopes of IP/DNS Fixes... nothing.. So we call Geek Squad.. They come out... Power down the Router then back on and it works just fine.. And they make 100$. Now heres my Question.. Is there a way for an ISP to send a specific signal to your Modem which enables a Connection though a dirrect line to the modem, but will disable/block any connection attempted though a network? Because honestly, I seems like they called comcast.. said fix it.. Arrived.. Did the "Power Down Pretend Like i did something to anyone who doesnt know computers" deal.. Then Walked out with 100$. Or am I just really unlucky?
