I was wondering whether there's any maximum (best practice) number of users that should be connecting to ADSL through a consumer-grade all-in-one (eg. DSL-2750U/Netgear DGN2200M) ADSL modem.
Currently there's a Billion in place in the office, serving 40-50 users and the connection is unstable. Put two separate wireless routers in front of it to divide up the wireless traffic so the next thing I suspect is the modem.
Should one need to use a Cisco 800 series/similar? Or should the D-Link/Billion/Netgears cope without much of an issue?
