I've noticed some issues with the 1.01 Firmware.
1. When reserving a DHCP IP, once you do one the router no longer list non-reserved IP's until its rebooted.
2. When changing Firewall rules (Gaming) it says a reboot is required. This was not required on the 4300
3. The OLED seems to have issues swtiching from showing kbps to mbps. The majprity of the time it list my Internet Connection at 999kbps.
