 ADSL wireless router
 D-Link DSL-G604T/AU V.B3,http://support.dlink.com.au/Default.asp latest firmware installed.

The problem,

After setting up to print using wireless access, printing works fine, there is however no longer any internet access available, wired or wireless ( from PCLOS, Mandriva, openSUSE, win7, or whatever!) To restore internet access requires rebooting the router and turning off the printer (or disabling its networking) similar issues with wired network printing.

The result,

I'm now pulling out my hair faster than it is falling out !!!!
Any ideas much appreciated.

A busy Thread !!!  This is what I have for now.

At this stage the following combination is working for wired.

1.) A static IP address set.

2.) The printer is booted before the the router.

3.) If the printer is booted after the router, a reboot of the router is essential, as is restarting the wireless connection at the PC.

4.) If any of these conditions is not met, the result is "network printer kills internet connection"

I have tested with openSUSE 11,2 and PCLinuxOS 2010.1 only at this stage,

This is my first encounter with network enabled printers, how much of what I have discussed here is standard, or to be expected? What is not?

There's not much to go on here but my first reaction was that possibly there is a duplicate IP address.

Normally, both the PC and the printer would use DHCP to obtain an IP address from the router and thus avoid duplication but you say that you have set a static IP on the PC.
I guess the first step is to find the IP addresses of the PC and Printer and make sure there's no clashes.

Is it possible for two computers on the network to be given the same IP address from the same DHCP server?

My guess is that your printer has a DHCP server and this server is interfering with the one on your router. If the printer has a configuration section, check to see if it says anything about having DHCP capabilities and turn it off if it does.

open the terminal and type "ifconfig" and not what ip address you get when the network works and when it doesnt
