More internet woes...

SHITTY INTERNET (yesterday)

My rubbish internet woes continue, the SSID on my new router constantly vanishing, and coupled (again) with bobbins speed, i have no idea WHAT to do, apparently the ISP technician tells me there is 40Mbit link to the next "point" my aerial is pointed at, So I SHOULD get perfect internet all day, every day... but no..
