Hi,

I bought a wireless card DWA-547 just a few days ago.
I installed it in my computer, but even after installing the driver from the CD or directly from the website (1.71b09 from http://www.dlink.com/fr/fr/home-solutions/connect/adapters/dwa-547-wireless-n-pci-adapter) i can't connect to my wifi.
It detect it once, at start of Windows 8, i am connected to my box for 5-10s, and then it disconnect and my box disappear from the list, and after 30s all others disappear too.
I have another PC connected by wifi with no problem ...

Thanks for your help, I tried a lot of things found on google, but nothing works

Wireless Configurations
Links>Wireless Installation Considerations and Managing Signal Congestion

• What wireless modes are you using on the main host router?
• 2.4Ghz Routers only: Try single mode G or N or mixed G and N?
• Channel Width set for Auto 20/40Mhz or try 20Mhz only.
• Try setting a manual Channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear.
• What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto TPIK and AES.
• Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?

How far way is this adapter from the main host router?

Hi,

Thanks for your help.
The channel is set to 1, and i'm using WPA-Personal. Nothing change with TPIK only.
2 other router in the area but my other computer tell me the force signal is 20-30%, my main host router is at 85%.

This is my main host router: http://nb4.toosurtoo.com/nb4/presentation.html

Does it connect if you turn OFF WiFi security temporarily as a test?

Same problem, it connect but after a few seconds it disappear

Only other thing to try would be to text the 547 on a different PC  with a different Windows version, with a different host WiFi signal, if the same thing happens then I would presume that the 547 is faulty and needs to be RMA or replaced.
