The downgrade to 0.5.2 worked as has the system that kept 0.6 but got the Engenius radio for the AP side. The downgrade still has the DCMA-82 as the 5GHz backhaul and an XR2 for the AP. No problems since the change so upgrading to 0.6.X will neeed some testing to be sure this is fixed. I'll post to the madwifi list as requested to see if the problem has shown up under othe distors using madwifi.

Thanks for the suggestion.

BTW, System A has has _all_ Ubiquiti clients and System B has a mix of Ubiquiti and Engenius CB3 + one Tranzeo (essentially the same radio as the CB3 but different software) so it doesn't appear to be a client related problem.

Hi Edwin,

I was hoping I have time to investigate this but time it didn't allow me to do so within 0.6.1 release time frame. After 0.6.1, I will investigate madwifi issues for sure

Meanwhile, you can post your questions to madwifi project mailing list. The madwifi driver version used by Voyage 0.6.0 is "0.9.4+r3772.20080716-1", which is also the same version from official Debian Lenny.

Regards,

More info...

On System B, I changed the Atheros-based DCMA-82 to one of my older non-Atheros Engenius NL2611 and have been up for 4 days w/o problems. The problem would typically occur a couple of times a day prior so I'm going to cautiously say it's fixed.

On System A, I swapped the DCMA-82 running in 2.4 AP mode for an Ubiquiti XR2 yesterday about 2pm. It has lost connection to the clients twice by 9:00a this morning. Running arp -an shows all the MAC addresses as incomplete (Nagios keeps trying to ping the IPs so the arp table shows the status. "wlanconfig ath0 list" still shows the clients associated but there is no IP connectivity. Doing ifdown followed by ifup immediately restores connection for another few hours.

The one thing in common between these two is VL 0.6. I will be rebuilding a CF for System A with release 0.5.2 and see if that fixes it. I have a number of VL 0.5.2 units with DCMA-82 (5GHz) and XR2 APs with no problems for months.

I'll let the list know my results with the OS downgrade. Any thoughts on how to fix this w/o downgrading would be nice. :-)

Very weird problem here now occurring on two different systems both with fresh and updated loads of Voyage 0.6

A note, I've used the DCMA-82 w/o problems as 5GHz backhauls but these two installations are the first as 2.4GHz APs

System A - ALIX with two DCMA-82 radios, one as 5GHz backhaul, the other as normal AP. System comes up and runs well, good throughput and power but will spontaneously lose all client connections typically within 12 hours. Dropping the interface (ifdown ath0:0, ifdown ath0) and bringing it back up restores function.

-----------------------

This was installed two days ago and has lost AP function three times. Due to bridging, I reboot the board to restore function previously but this morning even that is not working.

I'm going to try an XR2 this morning to see if there's a difference.

Anyone else seen this or used this radio as 2.4 AP successfully?

Thanks,

Edwin
