Router disconnecting

[#1]

Every night for the past week I've noticed that the PN router seems to disconnect at 17:58. My son tells me that it happens at other times during the day at the same times.
Any ideas?

Hi there,
I can see one or two disconnections at other times but there does appear to be a clear pattern for the disconnections at approximately 6pm.
Diagnostics don't show anything obvious so unless there's anything perhaps on a timer such as central heating that you can eliminate yourself I'd report a fault: http://faults.plus.net

I seemed to be having them but only on wifi, wired connections were stable. After switching to another router I haven't noticed any drop-outs. Hope this helps:)

Have switched router back to the Netgear D600 I had, this seems to have cured that problem but the eldest couldn't get world of warcraft to work despite port forwarding everything required. However gave it the dd-wrt software and all seems to be fine.
