And when i say all i mean all .
Happened yesterday at around 4 pm no net ,thought my adapter had gone legs up ,tried another one same deal would not pickup my router ,WTF tried another router and another modem ,none of them seemed to be transmitting no problems with son's laptop through the Ethernet ports all good ,gave up after 3 hours of removing and replacing things ..
Even my old netgear router would not transmit it's ssid just not there at all .
I checked everything through the interface wireless was on security was on i changed the ssid name the security password to a new one rebooted and nothing had changed no signal swapped cables modems anything i had to findout whats going on but no luck,gave up went to bed ..

Well today it just got stranger as the morning went on .
Seeing as i can hotspot all of the devices we have here i did just that i used 4 different devices and no luck nothing in the house would even show that they were active ,tried the wifes Iphone was the only thing that seemed to be alive in the house ,nothing would connect to that either my Daughters Galaxy note 2 10.1 was next ,well it showed up as a new network but this only showed up on 3 other devices in the house wifes Iphone my pc and sons laptop .
But even after in putting the code to connect it would not neither would anything else kept telling me incorrect password no matter what i did there was no way anything would work ,the network adapter on my wifes pc would not even enable same as mine ,i had a dlink usb adapter to try aswell that sort of worked every just would not work .

My sons laptop would display the hotspot but you couldn't connect to that either there was no way anything would work ,i thought my wireless network had taken out everything in the house ..

My HTC as a hotspot would not even show up ,same as my Galaxy Tab none of them ,and when they did no connection even when security was turned off and made as an open network the only device that found this was sons lappy nothing else ..
I have used these device before as hotspots and they work fine ..

So i went and got a 15 metre cat 5 cable from bunnings ran it from the Billion router to the netgear router to my PC plugged it all in and my wireless network showed up WTF checked wifes Pc sure enough there it is open network connected to it straight away as did everything else disabled wireless on my pc it is running cabled at the moment it connects to the wireless network now no problem at all HAD 2 APs cancels one turned wlan back on on the Billion and bugger me dead it works every device sees it and they are all connected right now ,it was like something had blocked all wi-fi in the house ..

I have had this network setup for around 7 years with no major probs at all except this ..
Everything is running now well most things i have to setup my WD Media centre the WII and my printer just strange ..
