I have a public network with 100+ users. This makes the Centurylink provided Zyxel 660R and 600HW freeze and lock up. I would like to put in a third party DSL modem in its place, but I am reading crappy reviews about a lot of them. If anyone else has suggestions about a modem that doesn't lock up and can handle this traffic that would be awesome. 10M download. Yep thats all that is offered in this area. Weird thing is we also have an SMC cable modem on our second WiFi and that never locks up. However we need both since our network always needs to be up. Thanks
