Hey there.

I'm having a strange problem. My goal is to create a "local wifi", which means a wifi without access to the internet. Then I want to access the wifi with a raspberry pi(which basically works, because i set it up with another access point from dlink).
The TL-WA7510N will be used as Access Point. I used the Quick Setup Wizard to set everything up, gave it a static IP and started it. Status looks ok and everything. Now the strange thing is that it doesn't appear in the wifi list of my computer (Windows 7) BUT it appears in the wifi list of my mobile phone (Samsung Galaxy S3). Also on the Raspberry Pi the wifi is nowhere to be found. The command "iwlist wlan0 scan | grep ESSID" only lists the dlink wifi.

Is there somewhere an option i didn't find to set the wifi visible or something? And why can I see it on the Android phone but not on the computer/R-Pi?

Thank you in advance

Michael
