We had approx. 50 people connected wirelessly to a (Linksys WRT54G) wireless router with a DSL connection (Motorola- supplied by AT&T) and while there are 30 or less people connected everything works fine. When more than that are on, we lose the connections and have to reset the router and modem. Then it works ok for a short while & then same problem. I tried upgrading to a Linksys WRVS4400N router and it worked great for 2 days, then also failed. What can I do short of paying the high prices to have a T1 installed? Is this a router problem or DSL problem? Is there a difference in modems that maybe a new modem would work?
