Positive: WPA3 is well working!

no him there :), but the problem is in ipv6, the connection state does not work, it will need to remove the check for the established and relayed to the forward.

Bonding 802.3ad Problem :

after i upgrade to this version the Bonding 802.3ad not working ( or stop about 30s ) i have not change anything and it's work without any problem in stable version

no problem with 802.3ad on RB4011

TimurA

After updating in arm an RB4011 has stopped working, there is no response in any ethernet. Nor can I recover it with netinstall since the ethernet ports are not activated when pressing reset.

RB4011, updated without problems.

Colleagues, a question: maybe an attack is being made on your router (wifi)? Does someone raise a point with the same mac address and what else does it do?

colleagues, disconnect Discovery on RB4011 and on neighboring Discovery devices. And check out the work of 5ghz. There is a suspicion that because of this the storm is on L2, and 5ghz has problems. The feeling is that all the problems are due to Realtek RTL8367.

TimurA

You can calm down, there is no difference in the revision of RB4011. Everything is just as bad on the new device.

the one that was tested is released in March 2019, my old one was released at the Sep of 2018.

All symptoms are the same.

not a true statement, on all models since 2012, everything is fine with 802.11d. The AP must broadcast 802.11d. a piece of shit - tp-link even does it. That is a known problem for pre-2012 devices. Your "everything is fine with 802.11d" most likely means that apple no longer uses 802.11d ...

TimurA

Apple's implementation of 802.11d is a real pain in the ass, indeed. And setting the correct country code on the AP in use won't solve the problem in some cases.

what about 802.11d?

This is an old thread.
I believe the correct value for 10ms is 0.01. Not 1.00.

5GHz is falling due to the fact that the client starts to reconnect frequently.
So why it fails when there's no clients at all? After a long period of idle?

My observations show that rts/cts disabling may help. Still investigating.

rts/cts disabling - not help.
look at answer from DanielJB.

I found a way to make at least this piece of shit work. We do the following: in the ACL for 5ghz, we write the rule limiting connection -120 ..-65 (or -67). 5GHz is falling due to the fact that the client starts to reconnect frequently. Mikrotik! solve this problem already, how much can you analyze?

Hello TimurA! What about flapping (link down/link up) ethernet ports with auto neogation ? I have this problem with differnet hardware and different cables.

Interesting find, good work.

I did another experiment with ipv6, turned off the access list in wifi and checked the reconnection from RB4011 to RB962 and back. While working stably. Miracles and only.

PS
RB4011 wlan1 fell again after 10 minutes.

TimurA

Interesting find, good work.

Today I tested the hAP ac scheme (RB962) and wAP AC with ipv6, everything worked fine. Why so with RB4011 - I do not understand: (

I disabled the ipv6 interface, checked roaming from RB4011 to RB962 and back (RB4011 channel 48, RB962 channel 36), there are no packet losses, it works.

TimurA

is ipv6 present on RB4011?
Nope. Also, I did not know about the duplicated MAC with SFP mentioned in the other thread, so it is running ok with the same MAC, but SFP is disabled.

I will try to cut down ipv6, and conduct tests again.

TimurA

I have been running RB4011 for more than a month and never had this reported issue on wlan. Not even when there was no client connected to it for a few days. So it seems it is not happening on all units. Can you export your config (between code tags) for this thread to see what you might be doing d...

TimurA

Those Apple devices are partly guilty, I think. There have been reports before that some Apple devices cause spurious radar detection, and the AP changes to another channel and listens for a while before it gets on air again. When the same device is still present, the same problem may re-occur. And...

Hi pavlov,

TimurA

the most curious know?
I received AirPort TimeCapsule for setting, and after that the data appeared on the switch chip on RB4011, which I showed above.
RSTP has been enabled.
Isn't that funny ?!

TimurA

after 5 overloads, data appeared in the bridge! What's happening?
You looked like before a switch-> host, but not a bridge-> host.

RTSP,

sorry, my mistake. Hardware offload for switch chip that RB4011 uses (RTL8367), while STP/RSTP is enabled, is not supported

TimurA

RB4011, if I turn on the RSTP, the switch chip stops working. By switch chip You mean hardware offload? Hardware offload for switch chip that RB4011 uses (RTL8367), while STP/RSTP is enabled, is not supported. use "protocol-mode=none" on bridge for offloading to work again. See this wiki ...

RB4011, if I turn on the RSTP, the switch chip stops working.

Very interesting, your switch chip works. I have a configuration through the bridge, and hardware offloading does not work .

Can you somehow customize the settings?

After today's 5ghz experiments, the following can be summarized: 1. switch chip does not work in bridge mode. 2. Mac adresss duplication on sfp and wlan1 3. curve driver for wlan1, does not work on 4 chains. 4. 160mhz not working. - This is superfluous, here 802.11ac does not work correctly. Excell...

TimurA, I of course agree with you that with the same MAC addresses on two interfaces this is a mistake of the developers of this Mikrotik model. Moreover, on the box from the device for wlan1 one poppy is written, and on the device itself another. But it all depends on how the device itself handle...

if i'll change the original 2.4ghz minipcie adapter with, let's say, an intel 7260... will ROS recognize it? No, Intel wlan chipsets are unsupported in ROS. Only Atheros may work.

and you think that everything will work when a conflict of mac addresses with spf? I think that this is not critical, because the interfaces with the same poppy are not connected to the same second-level network segment (Ethernet).

Does anyone have a problem that the 5 GHz wireless adapter stops working in the 80 MHz [Ceee] band and at 5180 MHz?

I know its frustrating guys. I will say that the RB4011 router only model is very nice. The Wifi model, at the moment, is just not ready.

3 months have passed, no movement in solving the problem.

Damn it! : D, As I have not found before? !!!! Colleagues, pay attention to the mac address sfp-sfplus1 and wlan1 they are the same! Change to sfp-sfpplus1 mac address. It's all about the same mac address with sfp and wlan1! How could this happen to the manufacturer - Mikrotik?! is another question!

TimurA

The solution was found quite by accident. thanks to the post WeWiNet - (https://forum.mikrotik.com/viewtopic.php?t=146029#p719239). I generalise - you need to set the antenna-gain in accordance with the device specification in the description - (Antenna gain dBi for 5 GHz = 3) - https://mikrotik.com...

TimurA

Any news?

Yes, no what news. Three months have passed, and there is no solution and MT does not even think about solving this problem. Many people ask me whether to buy, I show them this problem. Draw your own conclusions.

TimurA

It can be summed up, the problem is in QCA9984, after reading the forums on the chip, we can conclude that the problem lies in it - in its firmware. Otherwise, the device can withstand the routing load much better than the RB3011.
Only open the question when they fix 5ghz.

TimurA

i'd like to see someone test it in a Faraday cage, to avoid any radar interference.. i bet that will get the very same results.

+1

TimurA

funny, RB962 doesn't have such problems, if RB4011 crashes even with Windows 10, then RB962 at 5ghz does the same thing without any problems. No matter Apple, Microsoft.

TimurA

I now agree. I am seeing strange behavior on the RB4011, but only with the new Apple devices. uggggg......

Today, the MSI laptop on Windows 10, when copying a large amount of data, has crash 5ghz, four times in a row.

terrible device RB4011, and no timing fixes.

Run netinstall 6.44 on RB4011, did not help. The problem is either in ROS or in the device.

I see what you are saying. We have a full dual stack environment as well. All of our radios are set to "auto" for the frequencies and auto (XXXX) for the center channels. Maybe that is why we are not having any issues? We are stuck with US channel space. Tested in XXXX and carried the cha...

TimurA

Now in capsman RB4011 stood at 5240, RB962 stood at 5180. After 10 minutes of operation, RB4011 fell. IPv4 / IPv6. So it's not a problem in the central channel. RB4011 only works steadily if RB962 and RB4011 are on the same channel. the screen shows that 5ghz from RB4011 is not, crash. In general - ...

Either wait for Mikrotik to do 802.11w (doubtful), or lift the second point and configure Capsman for roaming. And translate the network name of the SSID to Unicode - utf8.

Apple uses a new chip, so presumably, a new driver too. This new driver did not follow RFC recommendation in one fragmenting method.

Then why did it work in CAPSMAN? Logically, the iphone xs max was not supposed to work in any mode.

One idea in case this really happens just without CAPsMAN: It sets a few defaults (e.g. WMM) that otherwise have to be set manually. Maybe it's related to that? Just a wild guess though...
