I have a WRT54GS v3 router. I just installed DD-WRT v23 alpha on it and now the power LED just blinks. I can't access it through the web interface and I dont see a wireless signal. What can I do to get it working. Or I just want to put the old official firmware back on the router. The documentation says that it will take a while on the first boot but 30 minutes is a long time.
