I guess you could disable onboard wifi and ethernet and try some USB wifi stick?
for the last 2 months i have had this red x appear and then disappear on my internet network icon. the net will then cut in and out as the x appears and disappears... i have done google search after search, tried every little scheme that i pray would help and nothing has... why is the happening and what can i do in order to fix it? if you need my specs let me know...
