I am trying to figure out the best networking solution for out fraternity house. We recently upgraded from hubs to managed switches. During some parts of the day, the connection is great, but it seems to struggle during times of heavy traffic. Here is our current setup. We have done no software configuration to the switches.
Connection: We have a 20 MB connection coming in to the cable modem. We have speed-tested the connection straight from the modem and get a consistent 20MB.
Router: From the modem, the line goes into a WRT120N Cisco Linksys Router. The modem is not broadcasting a wireless signal that can be used. See here.
Switches: Two lines leave the router. Each lines goes into a Linksys SLM224G. Each switch has 14 lines that leave the switch going into the rooms. See here.
In Rooms: Each room has 2 ports. Some rooms have a Wireless Router hooked up to the ports. Some rooms have hardwired desktops and some rooms have no connection to the ports but use other wireless signals.
Is our equipment/setup sufficient? Or is there something that needs to be done with the Switch configuration? Thanks in advance!
Could be due to "interference" issues, considering the fact that wireless routers can be plugged into the LAN ports in the rooms. One possible solution is to provide a centralized wireless network and disallow individual wireless routers in the rooms, makes traffic management relatively pain free.
Also if the wireless routers[in the rooms] do not have security enabled it could potentially be used by unauthorized users outside the fraternity house.
A wireless site survey at different times of the day could help find the cause......
Do ALL of the users get affected during heavy traffic time? I assume you meant internet traffic. Local traffic that's connected to the switch shouldn't be affect at all.
20Mbit/s cable connection is not a lot to share. You can use something like Ethereal to monitor what traffic goes on during busy hours. Personally I'd setup a proxy server between the router and the modem to control/monitor/cache traffic.

Extra NAT (wireless routers in rooms) will only cause slight additional latency to the end-user, it will not affect the entire network.
