Hello

Ubuntu 14.04 Desktop I usually connect to Internet via PPPoE over Wi-Fi signal from my router. The router gets the Internet from Ethernet cable which comes from my ISP into my apartment. So it's not a regular Wi-Fi Internet, WLAN just connects my computer to WIRED PPPoE I get from the ISP. Sometimes what happens is that Internet stops working and wireless signal in Ubuntu keeps disconnecting and then reconnecting by itself. And pppoeconf command can't finf PPPoE over wlan0. Then I have to connect the cable directly to my computer's RJ-45 and re-do pppoeconf and then it finds PPPoE over eth0 and then I get Internet. The problem is that for some strange reason, it works better when I use the former option, i.e. connect the cable to the router and use the wireless signal to connect to the PC. I just don't know how to fix this issue with my Wi-Fi.

SOLVED: Now Wi-Fi is back in order again. Maybe it was a temporary issue with a signal as someone suggested (meaning that maybe it's neighbors' Wi-Fi interfered). Who knows. It happens once in awhile and I don't know why...
