Internet persistent disconnection

  galacticz00 14:13 PM 14 Aug 11

Why is it that every time I boot up my desktop PC I lose my internet connection? I have a home network consisting of Xbox (wired), smart TV (wired), laptop wireless, and the PC (wired). This only happens when booting up the PC. My router is ZyXEL supplied by the PO my ISP. This didn't used to occur but now happens every time whether other devices are powered or not. PC windows XP/laptop W7. Any and all suggestions appreciated. Cheers gz00

Go into the Services window ("Start > Run", type services.msc and click OK) and check that the DHCP Client service is started and that its Startup Type is set to Automatic.

If that's OK, giving the PC's "Local Area Connection" a fixed IP address might help. Post back if you need help with how to do that.

Thanks mgmcc I checked the DHCP it is started and automatic. There are a few other network sounding items disabled i.e. DNS Client, could these be a problem?

Re your other suggestion yes I would be grateful for help with a fixed IP address.

Many thanks gz00

The DNS Client service should also be Started and its Startup Type set to Automatic, so try changing that first.

To allocate a fixed IP address, you need to know the Subnet (IP address range) that your router operates in. Run ipconfig /all in a Command Prompt window and look for the "Default Gateway" address, which will be your router's IP address:

Go to “Start > Run”, type…

cmd.exe /k ipconfig /all

...and click OK. This will show details of all network adapters installed in the PC. Make a note of the Default Gateway address.

Now go into the Network Connections folder ("Start > Run", type ncpa.cpl and click OK), right click the Local Area Connection and select Properties. Highlight the entry for "Internet Protocol (TCP/IP)" and click the Properties button.

In the TCP/IP Properties, click the option to "Use the following IP address" and type in:

IP address - 192.168.x.17 (where x matches that of your router's IP address)

Subnet Mask -

Default Gateway - 192.168.x.1 (the Router's address you noted previously)

Preferred DNS Server - 192.168.x.1 (the Router's address you noted previously)

Alternate DNS Server - (leave blank unless you know your ISP's DNS server addresses)

NOTE: To revert to automatic addressing, set both IP and DNS sections back to getting their addresses automatically.

Using the IP address ending in 17 should avoid any conflicts with other addresses in your network but if your router doesn't have an address of 192.168.x.1 then post back with its actual address.
