I have a wired ethernet with an old 3Com switch and an old Cisco switch, each connecting separate floors. My problems began when I replaced my 3G wireless internet access with Hughes Gen4 satellite internet. The Hughes modem is connected to the 3Com switch along with two computer, a NAS and a printer. The Cisco switch downstairs has two computers and a printer.\r\n\r\nI cannot get more than three computers to connect with the internet. Whenever I add one, another one loses internet connectivity. The one that loses connectivity is random.\r\n\r\nWhen a workstation loses connectivity, it connects to all the nodes on the network except the NAS but will not connect to the internet.\r\n\r\nIP's are generated by the Hughes modem using NAT and DHCP.\r\n\r\nThere are no computer name conflicts and no IP conflicts.\r\n\r\nHughes says they have no limitations on the number of nodes that can access it.\r\n\r\nIn my shoes, where would you look next for a solution?
