Possibly you are doing some procedure that requires the router to be reset.
My PC is connected to a LAN by a link from the main router. The problem is that most of the time, "Receiving" stops -- while "uploading" is ok. So of course, I won't be able to use the internet at all.
Then my link have to be replugged in the router (replugging it in my case doesn't work) in order to bring everything back to normal. Any ideas? I don't know if the problem's in my own PC, the router? or the LAN connection settings.
Sorry I'm not that great at LAN stuff. I hope I got everything clear. Any help would be appreciated.
