Ran for 5 days this time, then router automatically rebooted. I have not had to do any manual power cycles, but the router has automatically rebooted twice, once after 7 days, then again after 5 more days.
Not really a problem since the router is working fine otherwise. To be fair, I don't use the 4500 wireless much since I wirelessly access via a DAP-2553 access point which shows up as a LAN connection in the 4500....do have a lot of stuff on the wired LAN though.
1.21b02 is still the best for me after losing 1.02
