Thanks

What is better version RB112/RB523 for a stable wds point to point ?

cubacan,
yes mipsle is correct packages for RB112.
Do you have wireless connectivity or Ethernet to this router ?
Probably it is possible to access neighbor router and use 'ip neighbor' to access this router with MAC-Telnet.

If router is not displayed in neighbor list. You will need to get local access to router. It is better to take null modem cable and check the console output.

v3 should be good enough to establish WDS link.
