Can't connect to the internet when I change from WEP to WPA
« on: February 19, 2010, 11:41:22 PM »
Hello This is my first post.

I purchased the Dir-655 about a week ago, I had problems connecting to the internet but after a call or two I was able to get my wireless network to connect with the encryption set to WEP. I want to change to WPA and have gone through the process of changing and saving the settings the problem is once I do that I can not connect to the internet.

Can anyone help me resolve this issue?

Thanks in advance.

Did you power cycle everything?  Pretty much everything (modem, computers...etc.) need to be power recycled after changes like that.  Also you need to go through the configuration of your computers NIC's again.  Did you do all that?

Does your PC OS or NIC driver  support WPA?

Thanks for the replies. Computer/OS support WPA. I power cycled the computer, modem and router. Yet no connection. Changed the NICs as well and still no luck. Any other suggestions are appreciated.

Thanks.

What about EddieZ's comment/suggestion?  Did you find out for sure if your NIC's even support WPA?

I cannot think of anything else that may be causing it.

If it is XP < SP2/3 that that's the cause.
Are you sure the driver is WPA2 compatible? And did you choose WPA Persona in the DIR?


Give us some more exact details on your settings, versions and hardware used. This is looking like a guessing game already, so put some effort in it  ::)

Could you write down the resolution? It might help future users with a question concerning this...

i'll guess, deleted the old wifi profile and reconnected so that windows could properly detect the current encryption being used. Common problem when encryption type is changed and doesn't match what windows expects using the "old" profile it stored.

I had this same problem.  In fact I couldn't even go from WPA to Open security.  My solution was the same, you must delete the wireless profiles in Win Zero.  In my experience this is not required with PROSet Wireless but it was the only way I could get a computer running Win Zero as the wireless client connected.  Becasue all my PROSet clients didn't require this step it took quite awhile to find the problem.
