2 of my oldest rb433AH boards, in service for some 3/4 years or so started to give strange results.
I also have one rb1000 that can't even be upgraded anymore since it lacks sufficiant memory space...? (Yes, I did remove evertything possibe from the disk. Only a small package is accepted. But the 'system' package give the message 'unsufficiant memory')
One rb433AH I actually could revive a bit and is lying on my desk as sort of last resort emergency board.
Last event is a rb433AH working for 3 years now in same spot, in same function. It lost its Ether1 port already over a year ago. The Poe is not delivered by a powersplitter and the data goes in/out through E2.
But since a week or two it can't gets its time client updated anylonger. Settings aren't changed, are exactly the same as its clients and are exactly the same as routers higher up in the network (towards my main gateway, which is premium time server for all routers. Second time server is a server from the internet. I use two different one spread over all my boards. They work everywhere, except now for this rb433AH.
This specific rb433AH is not having any firewall filters enabled, nor are adjacent routers preventing the ntp protocol.
I tried to renew all the 5.24 package I use (system package is having the default ntp client), I reset the ntp settings to default and build them again. Router is rebooted several times. All it says it is waiting another 16second for the next attempt.... and it tries both given time servers....
Since two days this router now also witout reason starts to disconnect its ethernet port. It needs a reboot to make it working again.
This all happens in normal, dry but not too dry mild weather (so no ESD build up I presume).
We happen to have had a rainshower just now, and the board did nothing else than disconnection itself. Now it is dry it comes back on again and seems to stay on a little longer. But by all means, this is not the first rain shower in 3 year! What is happening? (Time is still not updated tho.)
I also have some rb333. when the work they are very good. But the older they become, the problems they give with unstable working (stalling, of failing ports.)
So, are the boards 'aging'? Do I need to start thinking of a lifespan of 4-5 year? Is that not a bit short?
