I'm planning to buy a Linksys router but I would like to know Linksys WRT series router if they need to reboot once changed some of the configuration to take effect. I have a D-LINK DI-524 router. Whenever I change for 1 setting such as open a port, it will restart and redial as I'm using PPPoE connection. All exisiting connection to Internet will drop and reconnect again. It is trouble and create problem to internal network user. Therefore I would like to know if Linksys WRT series and which model do not need to reboot once changed the setting and operate smoothly ? Even not offically support, how about flashing with 3rd party firmware that is feaisbile to do so ?
