Hardware reset needed, how?

It should have a reset button on the back, next to the power socket.

If not then it probably has one on the board but the hole is missing in the back of the case (I have seen manufacturers do this before!). The following is not for the faint-heated!... You can open the case & the switch may be there. Even if it hasn't, you can often see the contacts on the printed circuit board where it should be & shorting across those with a suitable implement will do the trick. Be very careful if you have to do this: although there are no high voltages present, there is enough current available to give you a nasty burn (or worse) if you should get it wrong!

I can't reset the huderle .please tell me.

I had this problem and i forgot the answer once.
Yesterday i found it again.. the answer , that is.
one end of the ethernet cable into any of the 1-2-3 or 4th connection in the back and the other end into the cable hole, the one that receives the signal from the wall or the modem.
Anyone please refrase this into something understandable, you won't hurt my feelings.
thank you

CP Port 1 to Internet Port should do the trick.
