Flukso unit losing wifi

by aboaboit on

Hi.

After a rather long and faithful service, it seems my unit has began acting weird recently. My router has a scheduled reboot each night and, normally, the meter reconnects automatically. The last couple of times, though, I had to power down both the router and the meter to re-estabilish the link. Last night, the link was lost way before the scheduled reboot.

Router log is full of lines like these:

Router is running OpenWRT r38226 with no config changes in more than a week for sure.
Other devices in the network function normally: a couple of laptops, a desktop with usb stick, two smartphones, an Android minipc, all work fine.

Any clues and checks I should run?

BR,
Andrea.

Hello Andrea,

Your FLM is still running r223. I would suggest you upgrade to the latest r232 firmware. Click on the cogwheels on flukso.net's top right corner. Then proceed to the 'devices' tab and click on the 'upgrade' link. An upgrade will occur on the next FLM heartbeat.

Thanks, I'll let you know if it fixes the issue. Kind of hard to diagnose because it happens very very rarely.

r232 is based on Attitude Ajustment, using an ath5k wifi driver while r223 uses Backfire with madwifi. ath5k looks a lot more stable than madwifi.

Ok, upgrade completed. I'll keep an eye on it. Thanks.
