    I recently connected a wireless router to my desktop pc, which has a cable modem, so that I could access the internet with my laptop . I set up a network and am able to connect/disconnect the laptop from the network without difficulty. However, if the desktop pc is not used for any period of time, it will not acces the internet and has to be rebooted (we leave it on most of the time). (On rare occasions it will connect without having to be rebooted.) I'd like to figure out what the problem is because it is annoying to have to reboot the computer any time we want to use it. Thanks in advance for an help.

    Do you really mean you connected a router to the pc, wheter than installing a wireless router behind a cable modem in order to create a wireless home network? I've got cable internet myself too, but with a motoral modem and a sitecom wireless router behind it I have wireless internet on all wifi enabled devices in home.

    So you need you pc to be on in order to have internet available on the laptop right?

    Do you know if your network devices use a fixed ( static ) ip adress? If a reboot resolves the problem it might indicate there being a ip problem between the different network adapters installed.

    Let's hear from you,

    Yes, that's what I should have said, that the router is connected to the modem. And I don't know if there is a static IP address-how would I go about finding that out?

    Having your network devices have a static ip is only interesting if you're downloading or gaming a lot, it is something advanced users in combination with port forwarding use to get better performance and connection, if you never touched this before it normally set to "obtain an ip adress automatically" and you probably don't have to worry about.

    If not you can check your ip being set as a static ip like this;

    -> Click on "Start" in the bottom left hand corner of screen
    -> Click Control Panel or Settings
    -> Right-click on "Network Places" or "My Network Places"
    -> Click on "properties"
    -> Right click on the network adapter you use for wireless and click "properties"
    -> Double-click on the "Internet Protocol (TCP/IP)" from the list under the "General" tab
    -> Check if it "Use the following ip adress" has been entered
    -> If there is information filled in, then you've got a static ip.

    All network devices set to obtain an ip adress automatically is the most hassle free solution, where windows configures all wireless cards for you, this is probably the case with you unless you've changed anything in the past.

    You could help by sharing;

    - The brand / type of router you're using
    - If you're using windows's built in wireless tool or software from your network adapter
    - Have you've disabled some services in the Microsoft Management Console in the past that relate to DHCP (Automaticly obtaining an ip) or Windows Wireless Zero config (Windows Wireless Tool)
    - If you have secured your wireless network (very important)

    Sorry to take so long getting back to your post. I think I may have solved my problem. The router I am using is a Netgear 108mbps wireless firewall router, but I was also currently using ZoneAlarm as my firewall (maybe a conflict between the two?), so I uninstalled ZoneAlarm and I'm going to wait a little while to see if that did the trick.

    i not sure if this helps but i had similar prob when i added a router to my cable modem (NTL). only i pc at a time (ramdomly selected as well could connect to the net.

    firstly, you have a router which is for cable and has ethernet port as oppossed to phone line i assume.

    secondly, have you cloned your mac address for your router so your ISP thinks you only have one computer (they dont like it when you have more than one, it gives them a excuse to charge you more i guess!!)

    sorry if these arent the answers you are looki for, im only a novice myself too! but good luck, im sure some one ere will sort it for you:D
