thanks
my os is windows 7 and my router is tenda n3
By "directly" you mean using a cable?
Because that sounds like your modem might be dying.
My modem's wifi started acting up some time ago, until finally it didn't work at all.
Like me you'll probably just need a new modem.
But before you do that, did you try all the usual stuff like:
Turn the modem off and wait a couple of seconds then back on, re-plug all the cables and so on...
