Wifi Direct. Is it a con?

Postby viking777 on Wed Dec 04, 2013 6:29 am

The wifi alliance says this about wifi direct:

Wi-Fi Direct-certified devices can form connections with nearly all the Wi-Fi CERTIFIED devices you and your friends already have. You only need one Wi-Fi Direct device to form a group


Well I have one wifi direct certified device and about 10 various wifi certified devices dotted around the house, and every single one of them turns a deaf ear to my wifi direct device (a samsung galaxy phone) - all I ever get is "No devices found".

I guess that leaves four possibilities:

I am extremely unlucky in my choice of wifi devices - possible but not likely.

My wifi direct implementation on the galaxy is faulty.

I am missing something obvious but crucial - happens often.

The wifi alliance are exaggerating - happens very often, not just the wifi alliance, but every technology I have ever used.

I have viewed videos about how to connect with wifi direct, but they all seem to be about connecting two phones together, very often two phones that are both wifi direct certified. So tell me, has anybody ever succeeded in connecting a wifi direct device to a wifi only device as the quote above suggests is possible?

I would love to know if anyone has WiFi-Direct going on Linux Mint 16.
Seems astonishing that this is not a widespread technology on computers given the number of pics and mp3s that move between phones and laptops !!

Anyone managed it. How ?

I think it is the above. My guess, based on reading this page, tells me that the main problem is in the terminology/naming used to refer to certain things. E.g., "Wi-Fi CERTIFIED" (note the ALL CAPS) doesn't refer to those ordinary wireless adapters the likes of USB dongles, PCI cards, et al. "Wi-Fi CERTIFIED" is a proper name/proper term/trademark.

Wi-Fi CERTIFIED = Wi-Fi Direct = Wi-Fi CERTIFIED Wi-Fi Direct™

So, Wi-Fi Direct only works between/among devices that are marked/certified as Wi-Fi Direct devices. I used Wi-Fi Direct before, to transfer files between my smartphone and my nephew's tablet. Both devices are "Wi-Fi Direct" compliant (both from Samsung).

I have a galaxy II Samsung and installed "Wifi-Files"(free) and it doesn't care about certs, it hosts a webpage and gives you the address so others that are on your network in the home side of the router [or wifi-box] can type the address in their browser and WALA file server shows up. Now safari on an IPad in their infinite wisdom doesn't support file downloading this way, nothing you can do about that accept get a real OS and a real Browser.
