3CRWDR300A-73, WPA problem

[blnl]

For some reason WPA encryption does not work properly. My computer connects to the wireless access point, but there is no data exchange.



iwconfig reports invalid crypt

eth1 IEEE 802.11g ESSID:"BLNL"

Rx invalid nwid:0 Rx invalid crypt:111 Rx invalid frag:0

What settings are recommended for WPA encryption?



By the way there are no problems with WEP encryption, or with NO encryption. Only WPA does not work.



I also tried upgrading to the latest firmware and resetting to the factory settings. It did not help.

Hello,

it seems that i have the same problem with a vony vaio (wifi chipset Atheros ar9285).

It works with no authentication or without encryption, however, with WPA it only connects ocasionally

¿have you solved the problem?

No the problem is not solved. I downgraded the security to WEP.

I also contacted 3Com support about this issue. This is their answer:

"We don't support the Linux configuration, so we wouldn't be able to help in configuring Linux. The advise we can provide  is to check if you are trying to use WPA and not WPA2, which is a newer standard of encryption his Linux device may have been using. Other than that, if you would like to talk to an engineer,  we can only offer the chargeable one-off  technical support option, we are talking about the connection issue with a non 3Com device that could imply that you would have to send us your Linux device to us to test it."
