Getting an autoconfiguration IP address

[happykappy]

On a lan with 10 PCs all XP. Have 1 2K pro PC. Connecting to internet via DSL modem Actiontek. All coming up with IP address of 169.254.xxx.xxxx and subnet of 255.255.0.0. The Actiontek DSL modem has an IP address of 192.168.0.1.
Tried to put fixed IP address and DNS server but unable to ping modem. Unable to find modem. ISP can see the modem. States that 192.168.xxx.xxx comes from windows OS. Is there a way to remove these IP addresses and let the ISP come back with the correct dynamic address to allow PCs to connect to lan and to the internet. Where are these IP addresses coming from.

According to their website, not all Actiontek DSL modems have routing capabilities - what model do you have? Will it route to multiple computers & act as a DHCP server?

 

[happykappy]

this one does not have any routing capabilities and the DHCP server is coming from the ISP

Try the utility discussed in faq779-4625

So, your ISP is providing 10 IP addresses?

Yes the isp is actually providing dynamic address for more than 10 PCs. All of them got the 169.254.xxx.xxx at the same time. I am wondering if it is malwareor spyware. I need to check that.

 

[NortonES2]

169.254.xxx.xxx address is provided by the OS when it is unable to find a DHCP server, not malware or spyware.

If it doesn't leak oil it must be empty!!

If the modem has the address 192.168.0.1 am I right in assuming it is using a 24 bit subnet mask (Default class C or is it using a class B subnet mask)?

If it is using a Default class C then you will need to give your PC's the following addresses:-

192.168.0.xxx

In other words
192.168.0.10
192.168.0.11
192.168.0.12
192.168.0.13

etc

If it is a default 16 bit mask (Class B) then the following addresses need to be employed:-

192.168.x.x

Hope that helps

Thanks all for the input. It turns out that the modem was defective and not allowing any DHCP addresses to be given to the PCs. Upon replacing the modem, all PCs immediately connected to the internet and got on the network. I had done the winsockfix and got rid of the 169.254.xxx.xxx IP address with the 192.168.xxx.xxx. I couldn't ping the ISP nor connect to it. I could access the modem, but not get out to the internet. So another solution to the 169.254.xxx.xxx could be replacing the modem. This was a DSL actiontek modem.
