lxsw20: Using one of the DrayTek DV2710NE modems my self now, so far it's been very robust.
they are, been very happy with mine, gone from resyncs every day or so to holding it solid for 2 weeks (minus the times when chorus pulled our lines again and toying with it :L)
still learning how to use it though.. but when using it right.. im yet to find flaws ... other than it being too secure sometimes! mainly being with netbios over wifi and google play (still yet to work that one out though)
