I set up an access point at my office with hostapd on a computer with a D-Link
DWL-G520 (Atheros) card. Here are the versions I used (Gentoo ebuilds):
- hostapd 0.5.2
My test client, a linux computer with a Intel PRO 2915ABG adapter is
experiencing some connection instability. It will connect fine, but after a
random amount of time, wpa_supplicant will reconnect by itself. I am using
WPA2 with TKIP (btw I can't associate to the AP using CCMP, but that's
The problem seems to be really random, as I was unable to find a way to

doesn't seem to suffer from this issue, at least not so frequently, if it
Here are links to the config files for hostapd and wpa_supplicant. I have also
uploaded some log files from both. I started hostapd on the server, then
started wpa_supplicant on the client, which connected fine. After about 10
minutes the reconnect issue happened and that's where the log ends, right
after the client reconnect.
As a side note, I left wpa_supplicant running while I was typing this email,
which took about 20 minutes, and it reconnected about 10 times in this period
I have looked thru the archives and searched the web, but I couldn't find
anything specific to my issue. I am sorry if this has been addressed before.
I don't know if the issue is on the AP or client or even both, so if anyone
have any ideas, I would be glad to hear.
Thanks for your help,
