Hey all,
someone with Chateau 12LTE who was able to get properly working with SIM card?
Modem is very unstable and connection after a while drops.
I just had my hAP AC2 powered down for a period (about 12 hours) - and on turning it back on I found it…wiped. Totally reset to default including wiping the file storage…where I had stored a couple backup configs. And being brilliant as usual I hadn’t downloaded them for safekeeping.
Given that this is my home router re-configuring wasn’t that big a deal. But…dunno if this has been seen by anyone else or not. I don’t think I pushed anything for reset purposes during the startup, and I don’t think anybody else fiddled with the equipment last night.
On the positive side - this theoretically means I’m starting with a clean QuickSet config for Home Dual AP so things should be setup optimally…right?

Are you sure they were in /flash folder, not in the root directory that is mounted to RAM?
I learned something new again. Thanks! Yes - I’m sure the backup files were in the root level - though they were there previously during other reboots.
It is normal that you lose all the files stored in the filesystem and not in the flash directory (and you should not keep a stash of backups there because it fill fill up the small flash space available).
However, it is NOT normal that the unit comes back with all the settings set to defaults. Settings should be always saved in flash.
I have the same problem the C.A falls quickly

Long story short:
- Quectel SoC show CA mostly when you use this link, when you have transfer then CA show up or stay active. This works perfect with EM12-G at M.2 slot.
- MikroTik with this SoC EG12 have problem with loosing CA after 5 minutes from no-speed time, check: https://forums.quectel.com/t/eg12-and-ca-failed-after-5-minutes-or-more-on-dynamic-aggregation/4685 or https://forums.quectel.com/t/em12-loses-band-in-ca-after-a-while-if-signal-is-weak/5150
Hey I do aspects of the Datacenter world in my day job. HW enabled wirespeed L3 routing on a single ASIC is pretty standard fare in that world, and has been so for some time. However, I wouldn’t look for policy based routes, full internet routing tables, smart queues, complex firewall filtering, or anything like that. So its a mixed blessing, and many datacenter network software failure scenarios center on the disparities between the capabilities of the asic and the cpu, which are basically the only two chips on a top of rack or spine switch. Its relatively easy to overwhelm the CPU and the usually PCIE interface to it from the asic. This is why there is so much todo about “control plane policing” COPP with these devices. A few million pps means nothing to the asic but a fraction of it will melt the CPU if its control plane traffic like spanning tree and routing protocol updates.
However you are correct in that only a few vendors provide routers that can forward millions of pps with arbitrarily complex routing policy and flow based shaping and analysis.
I am familiar with how CISCO does in on their MLS devices. Typically for wire-speed routing in the Cisco Switch world Cisco requires three entities to implement multilayer switching: the switching engine (SE), the route processor (RP), and the MLS protocol. The SE performs the switching function, the RP performs the routing function, and the MLS protocol provides for communication between these two devices. This aside, there is one very simple concept that makes it all possible: the flow. A flow can be defined as a stream of packets from the same source to the same destination using the same application. As an example, a flow could be an HTTP session between a source browser and a target server. In a Cisco MLS network, the initial packet in a session is routed via the RP, but all subsequent packets in that particular session are switched by the SE. The SE maintains a cache about these flows and can determine whether or not a given packet is part of an established session. If so, the SE rewrites the pertinent packet info as if it had been processed by the router and then switches the packet. This process is commonly referred to as “route once, switch many.” It occurs at switch speed, not at the slower router speed.
So in terms of MikroTik and RouterOS I do not see ANY functionality that mimics or deals with > wire-speed > Routing at the switch level.
On OSPF, I have mutiple vlans o nmy router. if their are other routers or devices using OSPF on the vlan then the VLAN is advertised to the other routers if not the vlan is omitted from the other routers. as a result have to setup static routes.
It appears to not redistribute the connected routes as it is not seeing them as active.
So have managed to get it to work.
What I had to do was add all my Vlans to one Area. lets say default 0.0.0.0
Before I was able to have default where all my routers connected to each other ie on a backbone vlan and then have an area with different area id for vlans not facing the backbone that are behind the router. now I had to add them all to the same area as temp work around. I think there are some bugs in OSPF. sure they will be resolved in upcoming version.
I think I am suffering from beta withdrawals. Lol
This beta has a lot of bugs in ac2. Is there any way to downgrade to 6.48 but keeping configuration?
You can force a downgrade and then restore the backup you made before you installed the beta (you made a backup, right?).
Or you could make an export of the currently running version and keep that as a guide (download it to a PC and open it in notepad)
when configuring a 6.x version after you have reset it to defaults.
Most paragraphs from the export can probably still be cut/paste into a telnet to the router.
It is the usual somewhat-laborious work of transferrring a config to another router, that is not streamlined well in MikroTik.
Can we expect the next beta version today as it is a Friday and over 2 months since the last beta release?
We’ve got 6.47.6 yesterday. And it wasn’t even Friday. I think that’s enough for this weekend 
micro SDCARD is not yet supported? Tile-Gx OHCI is not listed in usb resources…
Hello Folks
We are running routeros v7.1beta2 on a RBD53G-5HacD2HnD (Chateau LTE12), and have experienced some instability, all we can see when it happens, is one log entry:
router rebooted because some critical program crashed
I am not entirely sure, but I think we can provoke it, by changing port speed on an interface ex. to “100 half duplex” and back to “auto negotiate”.
How can I help the developers debug this, in a meaningful way.
Update:
We can replicate this behaviour 100% of the times, when we are changing port speed on an interface.
While of course a router should not crash under these circumstances, this is a setting that you normally should not touch. It does not work like most people think it would!
When you want to control the speed/duplex, keep the “auto negotiate” setting but remove the “Advertise” checkmarks for the modes you do not want it to choose.

Write directly to support@mikrotik.com or create a case by https://help.mikrotik.com/servicedesk
Attach the last supout.rif, check if autosupout.rif not generate automatically on crash ?
Thank you for your quick the responses.
I have systematically tried changing every possible speed and or duplex setting, it does not matter, the router crashes and reboots.
It will send in the suggested support files to mikrotik support.
Here is a workaround, for those who need might need it before a fix is committed, you can set the advertised port speed and duplex setting via the console, then the router does not crash.
Update:
Settings will not be reflected in winbox, only on the console, but it works!
