5.19 uptime routerboard 9h RB433UAH (power 24V 2A) problem not responding routerboard (graf statistic,stop traffic, no winbox,no telnet,no wirelles, ether,no SMB, no graf statistic!) (=random stop v.5.18) >> power off-on = OK functional again

Same board same problem!
I upgraded to 5.19, then i upgrade firmware to 2.41, after 8/10h of works board is down.
Power off-on don’t works.

Now we are taking it down from telco tower and then we chek it bettere.

I really hope is’nt a problem of 5.19 and/or 2.41 firmware, cause i have a lot of board upgraded with it

happened to me in beta of 5.18… and again in rc1 of 5.19… in a 435g
upgraded the firmware from 2.39 to 2.41 and later upgraded ros to 5.19 rc2 and its working…
had to netinstall back to 5.18 and upgrade firmware before going to 5.19 rc2

Please update changelog. 5.19 include 2.41 http://wiki.mikrotik.com/wiki/RouterBOOT_changelog

No NV2 changes? We have still problem with disconnect…

not for all devices. RouterBOOT upgrade is issued per-device, not universally for all.

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.

*) sniffer/torch + simple queues sometimes could crash router;

Will this improve x86 stability?

Minor Bug: RoS 5.19 NTP Client menu has a spelling error for Dynamic Servers still.

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

@ditonet

WebFig skin bug (direct URL access to disabled sub-menu pages) [Ticket#2012061366000346] still exists

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

your skin decreases the number of links, it’s not a security measure

[ditonet]

@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.

Regard,

normis, How is the device RB751U the stories?

[shrek777]

We have upgrated to 5.19 and mikrotik doesnot came back.
see attached picture.
all our 1500 clients and bgp are down now.
I think Mikrotik must release more stable versions.
Thank you

I have RouterOS upgrade v.5.19 very not stable. ( RB411AH + R52HN )
after 4-5 hours of online suddenly becomes hangs.
power off-on the router normaly again.
previously using version 5:18 no problem.
what’s wrong …???
thank’s for solution.

ccq starts dropping and rb starts to hang after a couple of hours and rbs must be rebooted or interface must be turned off and on

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.

Is there any changes in wireless.npk because in change log there aren’t

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

[msty19]

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

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

[sloth]

Can someone comment on stability of v5.19 on a RB450G?

@liu168

RB450G V5.18 upgrade to V5.19

ip > firewall > NAT table all information is missing.

Has anyone encountered the same problem with RB450G?

[djdrastic]

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.
