Is it not possible for you to have just the one network?
Is this really just one network with two Routers on it? One wired and the other a Wireless router?
Two DHCP servers pushing out IP addresses is usually just asking for problems.
Ethernet goes off when the machine goes to sleep.
Probably the solution is to reconfigure the office network.
I got iMac on my office. There is network issue on my iMac Desktop.
When my computer remains idle for long time (sleep) and wakes up again, I can ping into the same network device (say 192.168.0.0 network) but I am not able to ping into other sub net (say 10.2.0.0, printer network).
Restarting iMAc resolves the problem or unplugging the cable and connect to some other Laptops and connect back to iMAc works again (I mean I can access other networks again).
I turned of auto-negotiation and tried renew DHCP Address but it still doesn't solve my problem.
Restarting the computer and unplugging the cable and plug-in back is not a solution for me.
Does anybody has similar type of problem?
I will appreciate your help.
