Cant Access my Mikrotik Routerboard

Hello,

I have Mikrotik RouterBoard 750. I can’t access them. Can you tell me how I reset it and how I have to configure?
Which VPN Protocols are possible?

Hello max456, welcome to the forum.

Like other technical forums, it is normally expected here that questions come after searching. If I google “Mikrotik Routerboard 750 reset” for example, I find a link to MT documentation with answers:

https://help.mikrotik.com/docs/display/ROS/Reset+Button

In the same MT documentation and by searching on the forum, I expect you will find your answers about VPN.

If you have any later queries, feel free to ask. If the query is technical, please provide a statement of your aim, network diagram, and export of your existing configuration.

Good day.

  1. According to this page there is not a Routerboard 750?

Perhaps you were thinking about A ROUTER of the 750 series… known as the HEX lineup.
All start with RB750xxx(x) and the xxx tells us which model it is. I provided links to two of them found in mikrotik documents: https://help.mikrotik.com/docs/display/ROS/RouterOS.
You will see the discussion of the reset button which is a good place to start.

  1. If by chance you mean you are locked out and you cannot access the router upon a normal reset, then NETINSTALL is the technique to get back into it.

Suggest you read through this document, the excellent reference that phascogale noted.
https://help.mikrotik.com/docs/display/ROS/Netinstall
and an MT video: MT VIDEOhttps://www.youtube.com/watch?v=gzlLbIf3Dbk

Also this is provided based on practical experience:
Sage tips/advice on NetInstall if having difficulties ( USE ETHER1 OR the port named BOOT ) …
a. Regarding Etherboot for all devices, the most error-free method is - to press the reset button, keep it pressed, power on the device, and wait until the device shows up in the NetInstall window, then release the button. This holds true for the Audience as well.
b. Try to have a direct cable connection between computer and device (laptop to device for example).
c. A trick which helps for some is to only use a dumb switch in between, nothing else connected.
d. Also on THE COMPUTER being used to run netinstall, there may be issues if there are multiple NETWORK interfaces. If experiencing difficulties on the PC, it is best to ensure all other NETWORK interfaces are turned off.
e. Enable NETBIOS, over TCP/IP ( active vice automatic or disabled )!
f. Apparently, some users have success using a LINUX computer vice Windows… hard to believe but worth it if no luck otherwise !
g. A forum post on the subject with some ideas → http://forum.mikrotik.com/t/netinstall-sending-offer-but-not-installing/98794/1

User Comment: In my experience, Netinstall often fails to detect devices after the ethernet link to the MT device goes down and up again while netinstall is running.
Either place a dumb switch between the PC and the MT box to netinstall, so the PC ethernet link stays up during reboot while entering Etherboot.
Or first put the MT box in Etherboot mode, wait for the link to come up and start Netinstall after the link is up
.

User Comment: Use of displayed or entered mac-address vice IP address in winbox needs to be emphasized.

  1. Yes, the Hex series can do wireguard vpn which is the easiest one to setup and is available as an APP for android/IOS etc…
    Much depends on what you wish to accomplish with VPN.

  2. If you do provide an export of your config later, ensure you do not include your router serial number, any public WANIP information (actual ip address and gateway ip address) and any keys (used in vpns).
