I had a wireless network professionally installed through a third party that hosted the network. I no longer want to go through them and want my own network. I am trying to set-up a wireless network in large building. I have a cable modem plugged into a router and the router plugged into a 16 port switch. From the switch I am running 8 cat5 cables to wireless routers throughout the building. The routers are from the old network host so they automatically go to its log in site. I have tried to reset them to no avail. I am willing to replace the routers with new ones. My question is that how would I go about doing this? Am I able to buy new routers or access points and just plug them in where the old routers were? Also, would I be better off with access points or routers? Any help would be appreciated. Thanks.
