MikroTik Routers and Wireless - Products: Groove 52

  • CPE - Short for "Customer Premises Equipment", this term is used to mean a "wireless station". It connects to a (wireless) network, like your computer would, but doesn't create its own (like an access point).
  • Home AP - Simple access point. One SSID, no VLANs, etc.
  • PTP Bridge - Used for setting up a "Point to Point" link. Tends to be used to extend a single network to another site that doesn't have a cable running to it.
  • WISP AP - "Professional" access point ("WISP" is "Wireless Internet Service Provider", I think). It can serve multiple SSIDs at once, has VLAN support (to have each SSID be its own, isolated network, maybe with firewalling and routing between them), and other advanced things.https://forum.mikrotik.com/viewtopic.php?t=87961


WinBox is much more convenient than using WebFig.


Reset

Buttons and Jumpers
 • RouterOS reset jumper hole (no direct access, board has removed from case) – resets RouterOS software to defaults. Must short circuit the metallic sides of the hole (with a screwdriver, for example) and boot the device. Hold screwdriver in place until RouterOS configuration is cleared.

 • RouterBOOT reset button (access through the plastic door) has two functions: 


  1. Power On , Hold Reset Button
  2. at 10 sec release hold button
  3. at 20 sec , beep sound x 1
  4. at 48 sec , beep sound x 2 
  5. can ping 192.168.88.1


用呢個 (boot , 5粒 Wifi 閃完 幾下即放手 ) 
o Hold this button during boot time until LED light starts flashing, release the button to reset RouterOS configuration (same result as with reset hole)

唔好去錯呢個 Netinstall Mode

 o Hold this button during boot time longer, until LED turns off, then release it to make the device look for Netinstall servers.

HOME AP Basic :

Local Network

  • IP address: Mostly can stay at the default 192.168.88.1 unless your router is behind another router. To avoid IP conflict, change to 192.168.89.1 or similar
  • Netmask: In most situations can leave 255.255.255.0
  • Bridge all LAN ports: Allows your devices to communicate to each other, even if, say, your TV is connected via ethernet LAN cable, but your PC is connected via WiFi.
  • DHCP server: Normally, you would want automatic IP address configuration in your home network, so leave the DHCP settings ON and on their defaults.
  • NAT: Turn this off ONLY if your ISP has provided a public IP address for both the router and also the local network. If not, leave NAT on.

Configuring WEP with (40bit) static key
Create new WEP security profile named “wep_profile”:
[admin@MikroTik] /interface wireless security-profiles> add name=wep_profile \
mode=static-keys-required static-algo-1=40bit-wep static-key-1=1234123412 static-transmit-key=key-1
Statically configured WEP keys:
Different algorithms require different length of keys:
  • 40bit-wep (static-key-1) - 10 hexadecimal digits (40 bits). If key is longer, only first 40 bits are used.
  • 104bit-wep (static-key-2) - 26 hexadecimal digits (104 bits). If key is longer, only first 104 bits are used.
  • tkip (static-key-3)- At least 64 hexadecimal digits (256 bits).
  • aes-ccm (static-key-3)- At least 32 hexadecimal digits (128 bits).
Key must contain even number of hexadecimal digits.
