Re: when in tandem...
Draytek have released updated firmware
That's great, but I think the router is just broken. Not often a Draytek breaks, but it's not the first time either. I don't have Chromecast or similar in the house, and it was dropping out multiple times a day when I was the only person in the house and I was sitting running a Citrix session. Nothing taxing.
Anyway, Mikrotik is doing nicely for now, although the learning curve to set it up was steeped than Draytek :)
