Sorry for what might be a silly question, but are you doing a service network reload or restart after moving into the new network, or just suspending at point A and resuming at point B? I think that If you are reinitializing the dhcpcd and it isn't working, you need to work your way up the OSI stack to troubleshoot. In gkrellm there's a wireless plugin, load that and it will show you the layer 1 signal strength. Then do a service network reload at point B and tail -f /var/log/syslog to see what happens. My guess is that you're going to see a whole lot of shorewall packet-dropping because shorewall is still using the point A address for its wireless zone. > NOTE: of course booting my system into M$'s W2K gets everything up just fine > ... how the H* are they doing that?!? > Depends what they're doing... getting a DHCP address on boot isn't that big a deal, but autosensing that you've moved into a new network, getting a new address, and reconfiguring the built-in firewall to work with the new address is a little trickier. Not impossible or even very difficult, but you'll notice that W2K doesn't have a built-in firewall. > I am sorry - but after having shot my whole weekend, I am tired - mainly - of > the non-standard way of handling wireless networking in Mandrake (inherited > from RedHat, I assume), and also frustrated of having to read each script, > one line at a time, to determine what is being done when, and how, in order > to trace all the problems ... so here is my kind request to you: is there any > kind soul out there able to point me to a document describing in detail the > networking boot-up process for Mandrake 9.0, at least for the new scripts for > wireless?
