We have a network with about 200 computers, but normaly only about 50 will be connectod to internet at the same time. We have a cheap ADSL router (a tipical personal router) which hangs several times a day when there are many connections. We are thinking on changing the router and we are thinking on some routers like the following:
Cisco 857 Integrated Services Router puertos3Com Router 3040
there are others like the following but they are fom"home users" or "small offices" and i think they may have troubles too with many connections
NETGEAR RangeMax Next Wireless ADSL2+ Modem Router DG834N
Router Linksys WAG325N ADSL2+ Gateway - Wireless-N (802.11N)
we need ADSL2+, NAT, ethernet 100, we dont need wifi.
