It seems that in addition to the problem with NTP and WDS, the “Real-time Rate” is also broken in the current C64 firmware: It is always "0 Kbps" regardless of the connection type (LAN or WLAN) :(

1: 2: 3: 4: 5: 6: WDS works fine but no NTP sync even with a static route — is this a bug, or how to fix it? :(
