I am using L2TP ipsec on iphone 12 pro max ( 14.5 iOS version ) without any issue. Although i am not using tunnel splitting.

Hello,

Please send supout.rif file to MikroTik support.

I guess your best bet would be trying something with similar LTe Category card as huawei. As Ltap is using cat6 LTe card but huawei is using cat9. I suggest you would try this device if you are trying to achieve the best LTe speed possible - https://www.lmt.lv/lv/modems-un-ruteris/MikroTik_LMT_LTE18...

Be aware that new revision CCR use 12V input not 24V!
More than 12V will void warranty and damage any new CCR revision devices.

You are able to see if the seller is official distributor here - https://mikrotik.com/buy

There could be various other reasons for that, for example -
maybe they have a different firewall rules?
Did you fully reset the device when performed script /export and using it on other two devices?
Please check the CPU usage on each device when performing the test.

If you are using the wireless wire kit, 1km would be a little too far for these devices as they are supposed to cover the range of 200m>
Wireless wire dish and LHG 60G works better in this situation.

Please specify what RouterOS version are you using?
What device are you using?
I do not experience such behaviour when inserting "?" in terminal under "/system"

Unfortunately that will not be possible. All warranty/non-warranty related cases must be addressed to distributor from which you bought the device. Is there no other way, or can you let the dealer return the equipment to the factory for repair? I'm afraid that will not be possible. Manufacturer war...

I meant without any other configuration - firewall or something else.I have an ip in the same subnet but the problem remains!!!!!!

When you connect via MAC telnet to the device -
Are you able to ping the IP from the subnet IP you have given to the device you are not able to connect via IP telnet?

kristsd i will try to hard reset and just re-create user admin with my own password and no configuration at all and see what will happen.
It is very strange behaviour!!!!

Without a configuration you woun't be able to connect through IP telnet.. only MAC telnet.

Are you able to connect via Telnet if you re-create admin user with full access?
If you are not able to connect with the newest winbox version, problem could be in the configuration.

i will try what you suggest
but i expect stable connection with high speed 80 90 mbps
as i'm 2m far away from Wireless router

You could try reducing tx-power and setting tx-power-mode=all-rates-fixed
to see if that improves the connection ( bear in mind, it will also reduce coverage )

i suggest the following procedure: make backups try disabling hotspot and wireless package to free ram memory, then reboot to leave the device "fresh" (max free memory available) only copy the packages needed to establish the remote connection in your case maybe system, ppp, security, and...

Two options - 1. Removing packages 2. Save configuration somewhere to later apply it. Remove config from device. ( make sure to save IP address and route to be able to connect to the device remotely ), Make sure "/file" is clear and then make a reboot twice, and you will be able to downloa...

You could try to re-link both of the devices.
Hold 5 – 8 seconds. A new security key is generated. This is needed to remove a PWR-LINE PRO device from an existing PWR network.
after that, re-link -
Hold 0.5 – 3 seconds. For 120 seconds will try to communicate with another PWR-LINE PRO device.

From their webpage source - also twice as expensive, 299$ for a single unit.

Does this happen only in logs every time you connect to the device? Does it also open as many terminals?
To me this looks like a logging issue, could you check your logging settings?
If you can't find anything that could be the cause of it, contact support@mikrotik.com with supout.rif file.

Is there a chance that those phone's that can't connect has been locked to a specific area?
I can't find much information about galaxy s6 wireless module, but all for what i know, my galaxy s7 do support connections to 5ghz band, 40mhz channel width, with 5180/5500/5800 freq.

Try to lock it to 20mhz channel with 5180/5500 frequency. Try to use "Join network" in you phone using your ssid and password, if the network isn't visible, doesn't mean it hasn't detected it. If above options doesn't do much, i would try to create a hotspot from both of the phones and see...

It's simple, to netinstall just be sure you have unplugged the board from any power source, begin holding the reset button, and while you keep holding the reset button - plug the board to the power source, keep holding till you see it show up on netinstall tool.

You should select the right band in order to set the right frequency.

Hello, have you set up your AP correctly?

You could try upgrading through a Netinstall, as i think your total HDD size is somewhat less than it should be, that should fix the issue.

Hey,
To what version of ROS are you trying to upgrade?
