The issue with unavailable devices after 2nd reboot has been reproduced and it seems to be related when upgrading from 6.41.4 (or older) RouterOS/RouterBOOT versions. Our apologies for the caused issues, the fix will be included in upcoming releases. So anyone using older than 6.42 RouterOS or Rout...

hi, Do you have the ability to stop customers from upgrading the brick way? If not then withdrawing the release sounds a damn good idea as it is now over a month down the road. Unless you can instruct distributors to accept free returns/swaps of bricked hardware for swap for the duration? It is not ...

amojak

Well, in any case, and especially when equipment installed at customer locations is involved, you need to read the release topic of this forum before doing any upgrade. No matter if it is called stable, .0 releases have usually experienced major problems in the past, and careful users have waited f...

Ok so Files upgraded as expected but when i upgraded the routerboard version on two devices RB2011 access to devices was lost. Device is booting with ether boot displayed - have so far been unsucessful in factory reset and therfore cant use Netinstall iether. They both appear to be bricked. welcome...

They always read the forum, but for support problem, email then at support@mikrotik.com and you will get a ticket number and they will reply. Surprised? Nothing has really changed since when we first got an RB532 and RB112 with Ros 2 , except they now reserve being rude to you in private and ignore...

I still think it is a bad policy to release a new version in the stable channel and declare it the long-term version at the same time. You should move versions to the long-term channel only after they have proven to be free of obvious issues in the stable channel for some time. (I know that long-te...

hi all, Silence seems to be the response to this issue so far, Not sure how the firmware, if corrupt, is able to pass the checksums that are surely done before it is installed? We have just finished visiting customers and replacing bricked routers, fortunately we had NOT updated any infrastructure k...

I updated the firmware on a hPA ac2 without issue. But your mileage may vary. routerboard: yes board-name: hAP ac^2 model: RBD52G-5HacD2HnD serial-number: E5780DC..... firmware-type: ipq4000L factory-firmware: 6.45.9 current-firmware: 6.49 upgrade-firmware: 6.49 Hi, Thanks for this, i am hoping it ...

hi, Don't post often but a HEADS up for Mikrotik here. We have had a collection of RB750 / RB951 based routers brick after upgrading to 6.49 Ros and Firmware. I came here looking for this. I recently pulled an RB750 out of storage to use temporarily. I updated the OS but not the firmware and it see...

hi,

one other thing, how do i disable this potential time bomb, is there a way to cancel a firmware upgrade ?

hi, Don't post often but a HEADS up for Mikrotik here. We have had a collection of RB750 / RB951 based routers brick after upgrading to 6.49 Ros and Firmware. The problem looks to be with the firmware side. Usually they brick after a power cycle at some point after upgrade, we had one RB951 router b...

Hi All, After consuming masses of time chasing a very elusive problem with VoIP , we have finally found out the cause. Router OS 6.47.x basically. Our scenario is we use RB wifi routers, usually in bridge mode at customer locations but also in some infrastructure glue "switches/routers" an...

amojak

hi all,

well this is now 3 years old as a question, nobody has bothered to answer it from Mikrotik, the spec fails to mention if the unit supports 4 pair POE in which it should, so Netonix it has become.

sigh

hi, Why do they call this STABLE, it should be BETA at best. 6.47.1 on a Hap AC-lite and a 951-2hnd have both created a bridge problem where the router cannot be pinged or accessed from the same subnet via IP even when used as a basic bridged access point. It produces two "neighbour" entri...

amojak

interestingly an example exists on the wiki that does what we used to do succesfully basically > Solution Bonding interfaces are not supposed to be connected using in-direct links, but it is still possible to create a workaround. The idea behind this workaround is to find a way to bypass packets bei...

amojak

Hi, We have a problem in that something that did work fine now does not. So either something has broke or what we are doing was not officially supported. This relates to using Bonding and Active Backup to provide a resilient path over 5Ghz for 60GHz links of up to 1.7km. 60G is Mikrotik and 5G is Ub...

amojak

hi, you do not say how far away the power lead is from the battery and powerbox (length) or what the actual wire diameter it is. A cable that can "handle 2 amps" is not what you are looking for, what you need is a cable that does not droop under instantaneous high current spikes. The latte...

6.45.7 fixes the DNS exploit. It also seems to have created a port flapping problem on the CCR1036. What is of interest is that ALL the connected ethernet /SFP ports show the flap simultaneously with the time stamp of when it went "up". but does nto show the down timestamp or add any count...

amojak

hi, always your helpful self normis. i noticed this last night, all previous emails to support hit a wall, primarly as mikrotik decided to block me from their forum , support and even at one point blocked our IP ranges remember? Just after giving me a l6 licence as reward for being a top contributor...

amojak

i right so there are no static entries in the dns setup for our core router. our "ISP" is level 3/centurylink and i find it difficult to consider their DNS servers are hacked To add to this this is occuring on every other core MT router on other connections with other DNS servers too. So i...

amojak

i am not installing it but have a copy of what it downloaded, too big to upload here though

routeros-mipsbe-6.55.6.npk

amojak

the update server reports as 185.162.131.116 , in the netherlands.

something is broke as only the stable release exists and the version number is not real it seems.

perhaps somebody at MT needs to investigate this as it could be a nasty fake firmware attack

bill

amojak

well why does our routers report there is?

amojak

6.45.7 , why does upgrade refer to 6.55.6 ??

is this legit or some issue with your update servers?

amojak

hi,,
as per subject, what is 6.55.6 firmware and why is there no announcement of it?

bill

amojak

hi, An old thread but i was looking to find the same answer. The cost increase in parts is minimal to make POE IN on all 4 pairs, this would make things a lot better for customers who have hardware capable of feeding 4 pairs of power. Ideally a version of the passive injector that supports 4 pair wo...

amojak

hi, no mention of a recent routing bug we have experienced. Simple static routes stop working, to restore them you disable/re-enable them. Had this happen twice on two routers with 6.44.1 on them. One occurred after a power cycle, the other for no apparent reason at all. Has the dev team come across...

amojak

hi all Noticed this thread and have had a few 951's do exactly the same thing recently. the PoE just stops working, the RED LED goes out and nothing brings it back. the router otherwise is working fine. These have all been feeding ~3 watt loads and is proving costly. Perhaps we should dump MT wifi r...

amojak

hi,

oh well, that didn't work, tried 6.34 as well . seems i have a cable issue all of a sudden . does anybody know how to recover from the default password from resetting the config too. I had forgot these have one and I don't have the original sticker to hand.

thanks

hi,

i found the older beta at > https://download.mikrotik.com/routeros/ ... beta28.npk

will see if that restores it.

Hi, I thought i would upgrade to the latest beta from beta28 on a pair of LHG 60G links. the upgrade went through, however one end of the link the ethernet port now only syncs at 100 Mbps , in fact the 1000 mbps tick boxes had become unticked! I re-ticked them, applied and no change, rebooted, still...

amojak

Hi,

They appear to have removed this in the 6.44 beta

, no sign of an mcs option ..

bah humbug

I was going to force a link to MCS 0 as it doesn't need the speed of higher rates and this way i am guessing it will be a lot more stable during fluctuations, birds flying past the aerial etc.

My 2.6Km link does not want to link up. I'm using 64800 as not totally sure about legalities of 66Ghz in the UK yet. Little bit gutted as I expected at least something. We should be getting up to 70 GHz in the UK , will the hardware support this i wonder? There is no "country code" option...
