Some pros and cons from my PoV, having been on the ISP end of things at
one time:
+ modem/router combined means one box, less to go wrong
- it's all or nothing, if something goes wrong you replace the whole
unit
+ modem/routers are good for "normal" (baa-aah) consumers
- if you're not a sheep... sorry, "normal" consumer, it's often hard to
get the m/r to do what you want
+ m/r can do NAT
- m/r traditionally do NAT poorly - too many connections and their RAM
fills up. Sometimes you can just wait for the connection tracking to
fade away, sometimes you have to powercycle the equipment
+ many common problems are documented, workarounds exist, or patches
are in place
- you can't diagnose the uncommon problems, because you don't even have
something as simple as tcpdump
+ you can experiement with a m/r, then switch it into "dumb modem" mode
when you exceed its capabilities.
My choice would be to get an ADSL modem separately.
+ I can connect it to whatever I want that speaks PPPoE
+ If I change technology, I keep the router intact and
only swap the modem
If you go wireless, make sure it supports WPA and RADIUS at the very
least, and run your own RADIUS server. On top of that, stick a
NoCatAuth captive portal between the consumer wireless router and the
Internet connection. Give yourself a free account, and only allow other
people access to the Internet if you know them - regardless of the cost
of traffic, you're still responsible for their usage.
