hello

I wanna ask about how to downgrade from ROuterOS 3.13 to 2.9.51 ??

*reason = i have problem with hotspot , after i setting successfully without radius option ,... but after some electric down , my client get problem with hotspot connection ... i have restore but still no luck ... so i decide to downgrade to 2.9.51

Upload the 2.9.51 packages to the router and issue the following command from console

Be careful. You need to be able to access the unit by hard ware after you downgrade as it will disable the wireless interfaces.

first make sure your device supports v2.9 - most new RB models dont

Thanks for all advices
it`s work !!!

problem solved

does rb433ah support 2.9?
also, where can i download 2.9 from?
the main download page on the mikrotik.com page doesnt have anything old. all new.

433 does not support 2.9.51

Please send a sup-out to mikrotik support before downgrading so they can fix the issue for the rest of us. Also, try running v3 again in a few months to see if you still have an issue.

These units can run v2.9 or v3:
MIPSLE: rb100 series, rb500 series
x86: rb200 series, x86 PC routers

These units require v3 or newer:
PowerPC: rb333, rb600, rb1000
MIPSBE: rb400 series

If you are trying to run RouterOS v3 on a routerboard with only 16MB of RAM, you might need to disable some features to free up some memory. Do not try to run a Wireless AP with hotspot on a rb112 board, I found out the hard way about this.
I have most of my rb133c & rb112 clients running v2.9 instead of upgrading to v3.

sorry to digrace, what if someone wants to upgrade rb112 from 3.10 to 3.30, i have uploaded the packages and did /system rebbot for it to upgrade it yet, i cant acess thr rb112 for over 30minutes.


thank
