[Win7+] Software Accesspoint

Sometimes you just need to give wireless access to one of your little toys (i.e. Tablets, Smartphones, Raspberry Pis with Wifi – you name it) – but you got no wifi accesspoint with you. Starting with Windows 7, this ain’t a problem anymore. You can setup an software ap in just a minute:

Enter following code into your command line interface to start an software accesspoint with the SSID WiBridge and the password mh28-dyi9-txwt:

netsh wlan set hostednetwork mode=allow ssid="WiBridge" key="mh28-dyi9-txwt" keyUsage=persistent
netsh wlan start hostednetwork

You can check upon your ap via:

netsh wlan show hostednetwork

And you can stop it with:

netsh wlan stop hostednetwork

Update HP Procurve via XModem

console baud-rate 115200

After reloading the switch and configuring our terminal software to 115200 baud, we can start the XModem Upload via:

copy xmodem flash primary

After that command, the switch waits for an XModem datatransfer to beginn. So, just upload your new firmware image via your terminal software, using XModem.

Another reload after copying the image will complete the setup.

But connecting every electronic device to the internet disconnects
everyone’s privacy in reality. This paper examines the current
problems with an normal homebased “Internet of Things” system
and how the information technology industry is more concerned
with profit versus user security. Ultimately, we need to decide
for ourselves whether we want to continue using these types of
