@naz_eg Only solution for me was send it back and buy something else, sadly.

I tried both the older FW on the site, and some new beta firmware tech support sent me - neither worked, as the issue persisted.

I've had enough and am returning the router.

I'm concerned the issue is linked to the numerous "DSL Training" entries in the logs. The router is somehow detecting that my DSL connection is still in BT's 14 day training period, when it is not....

Still happening. Seems more frequent at times I'm *not* using the internet - it only happened once during the day when I was remotely working, but happened three times this evening and three times...

@DelESC how old is yours?
