Upgrade using SwOS firmware file “swos-css328p-2.9.bin” from > https://mikrotik.com/download > should be used instead.
Each time I upgrade, there’s endless issues. Resetting resets to 2.0 and then I’d have to pray and hope it’d upgrade to the latest with my settings intact, and then having to restore again.
This is on CSS326. Can mikrotik somehow allow RouterOS to be installed on CSS326 because honestly, SwOS is complete garbage. Yes I’m annoyed. You already have a good 1 year to fix the product and its still garbage.
I have a CRS317 that in version 2.8 often crashed the management, it was very slow access. The traffic flowed normal but the management looked strange.
@RobertF and @abrodkin
SwOS has supported IGMP v1,v2,v3 since v2.5, also many issues have been addressed since then and now in v2.9 there is an additional port option to disable unknown multicast flooding. We are not aware of common IGMP Snooping problems anymore.
If you experience problems using IGMP Snooping in SwOS, please, write to MikroTik support so your cases can be individually investigated.

Yes, the v2.9 contains the latest improvements for 10G → 1G performance issues and they can help regarding Rx Overruns in other setups as well.
Updated my CSS106-5G-1S from 2.8 and all appears to be working. However, after the upgrade, this is what the Upgrade page says:
Firmware
Current Installed Version 2.9 (built at Mon Jan 07 2019 03:04:37 GMT-0800 (GMT-08:00))
Latest Available Version 2.9 (built at Mon Jan 14 2019 02:29:12 GMT-0800 (GMT-08:00))
At the bottom, it says that there is an upgrade available. Tried the upgrade again and it still comes up with the 07 January version and not the 14 January version.
I have not upgraded the other three switches yet.
Upgrading from 2.8 to 2.9 on a CSS106-5G-1S causes severe traffic drop between 1G ports and 100Mbit ports. It’s random from 0 to 40Mbps.
Reverting back to 2.8 traffic increased back to steady 100Mbps.
I can’t any longer access webui on vlan management port… coming from 2.7… do i need to reset settings?.. what settings are required to be able to access webui from vlan99?
