Has the “ospf - fixed OSPF v2 and v3 neighbor election” included in rc been added silently?

3

All included fixes are mentioned in changelog. If fix is not mentioned, then it is not included.

4

The support said me that was supposed to be added in this release. It’s a huge problem that the OSFP has that bug.

5

*) wireless - improved WPA2 key exchange reliability;

What specifically improved? Thanks

6

Please Tell us more about etsi1

7

Update worked like a charm on hEX, wap ac, CRS125, CCR1009, CRS226, RB951G and cap2n - thanks!

8

What this mean?

9

*) hotspot - improved user statistics collection process

Does that mean it will display the statistics in real time?

No, it is not in this version yet.

12

Saleh9416 - No, this fix helps in rare cases when Hotspot service stops working properly due to incorrectly processed coherence between hosts and active users.

13

Problem with SSTP. RB2011 here.

I have 22 clients connecting to various services from their homes using SSTP with cert. After upgrading to v6.40.4 I’m able to establish the connection, but for example - I can’t RDP to Windows PCs. I can’t ping any internal address from my IP pool.

After downgrade to 6.40.3 problem is resolved. Everything works as it should. I can see and connect to any PCs on my internal network.

14

Where is wireless security profile TAB in Winbox?

15

CHR dude 6.40.3 → 6.40.4

all SNMP interface traffic reads are gone, showing ?/?

16

lotnybartek, eddieb - Send supout file from 6.40.4 which would be generated after problem has appeared to support@mikrotik.com and refer to this forum post;
Lakis - You did see this tab under “Wireless/Security Profiles” on 6.40.3 version and it disappeared on 6.40.4?

17

what are you doing?

all modules works of PPP-emulation → PPP-out interfaces stopped working!!!
in systems - ports - the usb interface disappeared !!!
for example sierra wireless mc7304 and other vendors in ppp-emulalation

curent version - not trust !
Fix it !!
sorry for my English :wink:

18

I updated to 6.40.4 one more time and now everything works fine. If smth wrong will happen - I’ll send you the file.

19

I’m also curious about the technical details of this change.

20

I can see it in terminal
/interface wireless> print
…security-profile=default
but not in winbox ->interface wlan1 it should be located under Wireless Protocol
not just on one device, problem appeared after 6.4x.
