So here is the current setup that I have done. There is a cable modem [Charter] that is connected to a Netgear switch [FVS114]. From the switch, I have ran a 50 foot cable to another 5 port Linksys switch. From that Linksys switch, I have connected a simple Access Point, and another 50 foot cable that goes to another 5 port Linksys switch. That second Linksys switch is also connected to two access points (one located near the second Linksys switch and the other located 50 feet away). All of this was done to cover wirelessly, a huge area [hotel]. For some odd reason, every local ip address I get is prefixed with 192.168.0.?? Why is there a zero in the third set? Usually I can change the gateway to allow that third set to be 1, 2, etc. but in this case, I am not able to change the gateway address in the original switch? Should I be able to change it in a typical cable modem? Also, customers will complain that they can connect to the network just fine, but the connection to the internet fails. I think all of these problems stem from a faulty cable modem. Any assistance would be helpful.
