To TapMyHed - did you have to manually input all the settings when you rolled back to d27? I would like to echo your comment about the timeout functionality which really gets annoying after a while :evil:
Thankfully the router hasn't hung yet but one more episode and I think I'll try d27
Cheers, Mike

Yes. To be absolutely sure everything was right. Billion fan recommends a clean set up after a firmware update.

Some of the earlier firmwares i used were ok, d23. D24 had issues with schedules on ssids and as usual billion fan sorted that right out with d27.

I didn't get a chance to use d27 instead leaving it ages and going straight to d41.

I'm really glad i put in d27 this week and put all the settings back in after a factory reset. It's been blindingly great and reliable and the webpage pops up so quick now so i can find tune the kids connections.

Let's face it, i really like the billion simply because managing kids devices and QoS is brilliant.

When the firmware is right billion can't be beat.

Many thanks for that - from reading other posts on the forum, I think firmware pre d36 has to be manually configured if rolling back. Ah well - I will only roll back if I experience more hangs or if I'm feeling particularly bored ;) Cheers, Mike

My router hung again this evening in the same way as described earlier (ie) it's lit up but no response to pings/loss of internet
The last few messages recorded in the log were:

Can you confirm which firmware version you are running?

Hi Mike

Can you send us a backup of your config with admin password set to admin so our engineers can check your settings
(email it to support@billion.uk.com also if you can answer the following questions within the email)

1.How long does it take for the lock up issue to occur per cycle ?

2.Can you confirm if syslog Log Level and Display Level is set to = Debugging ?
