8800NL R2 gets stuck after upgrading to 2.52.d3

Posted: Tue Aug 22, 2017 5:04 pm

Hello we are talking of:

Model Name BiPAC 8800NL R2
Software Version 2.52.d3
DSL PHY and Driver Version A2pvI042j1.d26q_rc1a

after upgrading to 2.52.d (reset all configuration from previous firmare and configured back from scratch) the router will be unaccessible for some seconds (10-20 seconds) time to time.

The router won't reboot, it is not pingable and the network doesn't work. Then suddendly the router works back again. No other network issue, it must be something related to the router that didn't ever happen before with the previous firmware.

From the log I can see:

How to solve?

Thanks
Do you have any P2P connections running?? (eg torrents)

Try to lower max number of sessions

You can also downgrade the firmware to confirm if the issue re-occurs again http://www.billion.uk.com/esupport/inde ... on-250ad13

No torrent, nothing special. Yes, it is a busy network (about 50 from pc to voip phone to ip cameras) but we don't have this problem with the previous firmware (we upgraded due to other kind of problems with wifi).

Any solution?

Can you submit a ticket on the following link http://www.billion.uk.com/esupport/inde ... ets/Submit

Also if you have IPv6 enabled, try disabling it under 'Configuration >> LAN >> IPv6 Autoconfig' untick the 'DHCPv6 Server' and 'Issue Router Advertisements' options, apply the change and see if the issue re-occurs
