Are you able to ping the printer or get to the printers web panel if it has one? if then the current setup isn't working and you be able to print even if you put the printers IP address in when setting up the printer on your machine. You might be able to add static routes on the routers instead of the client machines to route between the 2 IP ranges. then this mean it wouldn't matter if the machine moved from wireless to lan as it should still be able to get to the printer The best solution would be to disable DCHP on the linksys router and turn in to just an access point (I think you might also have make it act as bridge, I am not sure how this would be done on the linksys wireless router, but we have done it at work with some netgear wireless routers) then the linksys router will just pass the wireless traffic on to the lan and from the lan back to the wireless clients without modifying it. It would be a Layer 2 device if you know your OSI model this would then allow both the wireless machines and lan machines to be on the same range (192.168.1.1) While I am not sure of how to do this on a linksys router if you let me know the model number I could have a look at the manual and see if I can work it out. -- Next meeting: C4L and Bournemouth, Wednesday 2010-06-02 19:00 http://dorset.lug.org.uk/ http://www.linkedin.com/groups?gid=2645413 Chat: http://www.mibbit.com/?server=irc.blitzed.org&channel=%23dorset List info: https://mailman.lug.org.uk/mailman/listinfo/dorset

Can you ping the printer from the wired Host? 2. Can you set the default gateway on the Draytek-to-linksys port to the IP address of the linksys port 192.168.1.10 ( Which should be a fixed IP address, not DHCP obtained) and use the port on the linksys that can be set to the default port for the printer-- Forget it - I forgot that it was wireless. Maybe the first half of 2 will work, but then I would be concerned that you lose all connection with the outside world.

> When I connect any machine using wireless the IP address is 192.168.2.x I'd guess you've maybe got two dhcp servers running - check your config on the linksys and draytec units. Maybe one is serving out the 192.168.2.x network without you realising. You could try snooping your network for dhcp packets with something like ethershark or tcpdump or whatever your favourite packet sniffer is, while resetting your printer, to see which IP is serving out the DHCP offer packets. cheers, --justin -- Next meeting: C4L and Bournemouth, Wednesday 2010-06-02 19:00 http://dorset.lug.org.uk/ http://www.linkedin.com/groups?gid=2645413 Chat: http://www.mibbit.com/?server=irc.blitzed.org&channel=%23dorset List info: https://mailman.lug.org.uk/mailman/listinfo/dorset

Serve up dhcp (192.168.1.x block) from the Draytek for client PC's, away from your fixed ip range. This will serve out ip addresses for lan and wireless (through the Linksys) clients. Linksys fixed 192.168.1.x ip address, DHCP server off.
