Hi list
need advice i have found old but working 751U-2HnD
and want to use it as a simple LAN router
but after installing v6 LTS or STABLE version i see that CPU 100 % load on an Idle (2-3 PC – only network browsing)
so i revert to v5 Router OS – better but still not a good choice.
Can I use this device or it is so old that i have to trash it . ?
Regards and thanks for advice
ROS v6 has quite different configuration than ROS v5. If you simply upgraded router while not touching configuration, then the resulting configuration, as created by upgrade scripts, might not be optimal.
I suggest you to export configuration (that’s not backup!) by running command /export file=config_export from terminal window, transfer resulting file to management PC. After that upgrade ROS to latest long-term (as of time writing this it’s 6.47.9) and reset device to factory default (in this order). Then make minimum configuration changes, you can use the exported file (open it in any text editor) as a reminder/template … but be sure to follow current configuration concepts.
If, after doing it, router still can’t cope with workload, then yes, you may have to replace it with something less obsolete.
