is it related to metarouter that have discussed at another thread about running openwrt ?

Is there a way we can see the changelog for 2.41 ? for us who have devices that it applies to it would be helpful.

Honzam,
If you are using p2p bridge with NV2, then try these wireless settings:
Channel width - 20Mhz - IMO this setting is the most important for connection stability..
HT AMSDU Limit - 8192
HT AMSDU Threshold - 8192
HT AMPDU Priorities - 0,1,2,3,4,5,6,7
HT Guard Interval - any
Adaptive Noise Immunity - Select proper for ap/client
Enabled NV2 Security

It helped me.. (p2p connection over 25 days).

RB433UAH, RB100AH

Problematic is RB433UAH. Seem that my issue disappeared.

RB433UAH very unstable last 2 days.

Before:
1. Noticed very bad sound in SSTP VPN between RB433UAH and RB110AH.(Ticket#2012070666000456)
2. Tried to downgrade RB110AH from 5.18 to 5.14
3. Lost my cert - and can't import it again (Ticket#2012071166000339)
4. Upgrade to 5.15 - same issue
5. Upgrade to 5.16 - same issue
6. Upgrade to 5.17 - imported my cert

Because of my experiments I downgraded RB433UAH from 5.18 to 5.17, to not lose cert. In 5.17 <--> 5.17 I noticed same jitter in SSTP and back to 5.18 on RB433UAH.

As result
1. RB1100AH - 5.17
2. RB433UAH - 5.18 - very unstable(Ticket#2012071766000542) - 5-7 reboots per day with 100%CPU load. I this it depends of traffic maybe, because night it alive. Uptime was 20-39 minutes. Sent ~ 10 supout.rif

Supout.rif file have no indications of any software related issues. Please, check
your power/grounding/ examine board for visual damage.

3. RB433UAH - 5.19 - very unstable.

Now
1. RB433UAH - found my config before downgrade(from ROS 5.18).
2. Restore my config on 5.19 and now uptime is 1d 18h

it's not a bug, it's how it was designed

@Chupaka
Month ago Normis promised me (by mail) that MT will try to fix it.
This bug exists only for sub-menu pages, eg. System/Users,
but not for top-menu pages, eg. Queues.
For me it's very useful to permanently hide some Webfig pages from end users.

What exactly hangs? Can you ping it - what do you see on the serial console if you have access to it?
Do you see a kernal panic - any autosupout.rif file generated?

router can't ping. I can't get access to the router. the only way is to turn off the power and turn it on again.
problem has been resolved after a downgrade to 5.18. Current router is working properly.
7h of works routerboard is up and working fine.

I have the same problem but on X86 machine, router can't ping. I can't get access to the router
the only way is to turn off the power and turn it on again,
I have only few packages: advanced-tools, dhcp, ntp, ppp, routing, seciurity, system.

this is not first time that mikrotikls distribute version with status/comment "stable" for version that give users a very serious errors with stability.. This policy is very disappointing :/

5.16-5.17-5.18 stable version I've had disappointing. Impair the confidence to Mikrotik

if ur trying on x86 maybe its unstable because its never tested on this pc but there is always support

5.17 and 5.18 are stable (except something wrong with nstreme since v5) but there are always bugs and there will be because
Mikrotik is always trying to import a new futures witch need time and money witch in some case is bad
like IP6, UBQ (airmax products) still don't support IPV6
to the point I dont need to use IP6 protocol for P2P link just I need working nstreme or nv2 like in UBQ case Airmax

Upgraded to 5.19 on a RB750 , and have had it on multiple occasions had all the LED's flash to green and just flat out will not respond until a power cycle.Unsure if it is hardware/software/firmware related.

I was previously on 3.38 boot and 5.9 clients and 5.17 AP in nv2 mode. Moved everything to 5.19/3.41 and so far no problems, all boards RB433AH and RB493AH. WiFi is as stable as before if not a bit better (fewer disconnects).

Sometimes it's impossible to test everything in the lab environment. Here's what works for me:

Upgrade 2 weeks after the release, scan forum for issues related to the release
Upgrade one client, no firmware upgrade
If it's stable: upgrade second client ROS and firmware;if unstable: revert or upgrade firmware
If both clients stable upgrade few more
After few hours upgrade AP and check if newly upgraded clients are stable; run in this configuration for a day or two
Upgrade everything else if network stable, roll back if not.

Why u will upgrade?

Security updates, unannounced improvements to wireless and better support (MT support tends to request that you upgrade before offering any help)

Speaking of wireless -5.19 has less client disconnects but falls back quicker during interference and offers less bandwidth in PtMP. I will roll back the AP to 5.17/routerboot 3.38 when I'm certain of that.

Hello Folks!

Majority of our RB411 boards, RB333, RB600, RB750G, RB450G, SXT-5D is now updated to 5.19.
No problems so far, all working fine, noticed little less CPU on some boards to

In 5.18 two times on SXT-5D, we did experience some SNMP high CPU consumptions that took 100% CPU, dieable and enable SNMP solved the case, for returning some month later. Also RoS <5.18 in past we did have same issue on RB333 boards and also on RB450G, it has fully dissapaired in 5.18 and up. Now and then we face an crashed console, nothing that affects any production

Good work MT!

When we downgrade this mikrotik become v4.17, the device become cannot be access.
Trying netinstall, but no luck. Trying to reset, still cannot be access. The only thing that I can found after downgrade become 4.17 is only one beeping sound and then there's no second beep sound heard any more after that.
