kernel: nf_conntrack: expectation table full

Post by BigDaz » Sat Mar 30, 2013 12:56 am

I'm having trouble with my 7700N, for nearly 2 weeks my internet browsing has been very slow and the router log is full of this error:

Other people have had the same - http://forums.whirlpool.net.au/archive/1698921
Just wondering if anyone has any solution to this.
I've rebooted it, done a factory reset, tried the latest firmware, disabled uPnP and I'm not using torrents.

I have been having this exact same problem for about 1 week now.
I am also constantly having very slow browsing any many browser timeout errors.
After resetting the modem I get about 3-5minutes of good browsing.
As soon as the internet slows down, these errors show back up in the log

Please sumbit a ticket here http://www.billion.uk.com/esupport/inde ... ets/Submit

Please attach your config file, and let us know the firmware version you are using, and finally make sure the username/password is set to 'admin' and 'admin'.

Just for anyone else getting this I think the solution is to turn the firewall on.
It's under Advanced Settings -> WAN Service -> Edit
If it's active already, disable it and then re-enable it.
It should fix it immediately.
