just want to activate to network cards in same machine
 

i m just trying to activate both network at same time in a one machine

1. Dlink DWL-G520.which have connect to internet via wirless router
2. 3com wired card

problem:

when i activate wired card through system-config-network. browsing on browsing is stop at wirless card. but when i reactivate my wireless card with command service NetworkManager restart and NetworkInfo. the wired card have been deactivated.

My guess without more information is that one of the services loads it's own configuration file, and restarts the network interface; then when the other is used, the other file is loaded and the service restarted. Based on this assumption I would think you would either need to use 1 of those tools to configure BOTH interfaces (or both tools setup the same so both interfaces are in both conf files) OR you would need to do some custom work on the config files directly.
