the hardest thing in tweaking and the worst possible scenario that could happen is misconfiguration to the point that you can no longer access your SM via 169.254.1.1 even you try the 169.254.3.3, it happened to me once then I have read a thread about a default plug since you need to buy it what I did is I soaked the plug into a glass of water and it worked stupid me and made a mistake again and now even the glass of water did work this time I have decided to went to my roof remove the strings of wire attached in my pole of canopy and then unplug and plug the cable while my brother was checking if it was working.... ha it went back since then what I did is always right down the steps so I can backtrack it. now here is my speed during so called prime time 7pm
