I have a problem with my Internet staying online. I have a Toshiba PCX1100U Cable Modem, and it's attached to a NETGEAR EN104 HUB, and I have one connection going from cable modem to hub, one from my computer to hub, and one from another computer to hub. All internet works, but I'm having problems keeping a connection. Whenever my computer is idle, or there isn't anything transmitting info (like my clicking on a link), then theres no activity at all, and the PC light on the cable modem turns off. To spark it back up, I usually have to click a hyperlink like 10 times for it to work up. This is really annoying, I don't know if this is an ISP issue or not. But I guess it's been happening for a while. Oh yea, I have an NETGEAR FA311 PCI ethernet adapter, and rj-45 for the cable's. There is a different IP address for each computer (so no ICS) Any help/input would greatly be appreciated.

do you have the latest firmware for the Toshiba and the Netgear hub? Do you have the problem if you connect just one PC directly to the Toshiba?

Yes I have tried everything. Everything except, using USB and RJ-45. I don't know if this will help any, but It was like this when I first got Road Runner. But since I used both, I was getting 2 IP's for my computer, and 0 IP's for the other.

Does your ISP know to give you two IP addresses for the two computers you have connected to the hub or are you just setting up different IPs yourself? With your current network, in effect, both those computers are DIRECTLY connected to the Internet and so they need separate IPs assigned by your ISP. By default most ISPs only assign you one IP. A router, not a hub, allows sharing of a single IP address on the "Internet side" of your router to multiple computers on the "LAN side" of your router. I'm not sure if I explained that clearly. See the diagram here but ignore the "Home PNA" part of the network. This is the configuration you say you have. See Note #3 below the diagram. Maybe you need a router or just connect one PC to the modem and put a second network card in that PC and set up ICS (Internet Connection Sharing) so you don't need a hub at all.

That is not my problem, I have IP's for each of the computers, I'm paying for 2 IP addresses, not 1. But I'm still not getting a stable connection.

if you have tried all the options, and the only thing in common is the cable modem, then it must be the cable modem.

Does the Cable modem support the http://192.168.100.1 access to its configuration and status? If it does, make sure the the Downstream signal strength is well above -15 dBmV (should be near 0 dBmV) and the SNR is above 26. If not, you have a cable signal quality problem (bad cable connections, damaged cables, or wrong type or more than one splitter). Noise and low signal on the Cable side of the line my be making the ISP's HeadEnd modem go deaf to your upstream signal when nothing is being transmitted and it has trouble sync'ing up again. Try removing any source of interference and hook the cable modem up directly with nothing else attached (no splitters) and see if the problem goes away. Also make sure the modem is not close to the system power supply, the display monitor and speakers and speaker wires.
