thanks for all the replies guys! i got my hands full this couple of days so didnt have much time to reply.
like bob leonard was saying, we're trying to make our network as reliable as possible so we can get that headache out of the way. the biggest setups that we usually make consists of a 12 per side FOH(DPDA Vertec), 8 per side SOH(DPDA Vertec), plus we also include our itech amps in the network, which is usually about 7 per side. giving us all 54 network addresses, and we have to be able see how they are all performing at the same time,. now im thinking this might be heavy on the home class router(linksys) that we are using. That's why we end up losing one or two cabinets on the network from time to time but then eventually get it back and maybe that's why the network is sometimes reacting slow. plus we have to connect our tablet wirelessly on the network too, but eventually we lose connection to the router even if we are only 6 feet away.
i'll try to look up on the dell routers/switches and maybe some cisco as well. thanks again for all the suggestions!
