Its not looking to good right now for the Asus modem routers. In view that both models share some similarity then it would appear that ASUS need to pull their finger out and correct the reported issues if they want this router to continue to sell.
As with the DSL-N66U, Ive now added some further comments.
Their (cable) routers such as the RT-N66U seem to get such favourable reviews, but it would appear very badly let down on the DSL side.
Hopefully issues can be resolved with new firmware updates.

atm the only ones in the running seem to be Billion & ZyXel winning hands down... with TPlink bringing up the rear. I would have loved to have got my mitts on a TG589vn to test one of those.
TPLink's is stable and good value for its price.. but in all honesty they too could have also had a big flop on their hands. Because I beta tested this unit I was able to give them a lot of feedback which to TPlinks credit they listened to and resolved. They delayed shipping until I'd confirmed the new f/w was stable. But if it had gone on sale in its original state then it too would have been bad on a heck of a lot of lines. If it struggled to maintain my 80/20 line (and caused the DLM to kick in for me), then it wouldnt have been a pretty picture in the wild. It is stable now, but unfortunately the Lantiq chipset doesnt quite seem to be able to match the BCM performance :/ In all fairness they do however appear to match performance of the BToR ECI modems.. and they do seem to be taking my comments very seriously about the lack of linestats.
