Ok, first of all, I'm new to this forum and MikroTik. I already have read a lot, but I must miss something very basic.

I received the (new) RB2011UiAS-2Hnd-IN as I've read it should be a fine router...

Basic: I can ping the unit
http://IP does not work
telnet IP does not work

First connected RB2011 to my general network, it should receive IP and with my desktop on wifi I should be able to find it and connect to it. I use only Mac's, so the Win admin program I ran by Par. Express.

The software could not find the unit. Guessing it could had to do with router - wifi - emulation ...
Took my laptop (also mac), direct connected to Router ETH1

Can ping, no https or telnet.
Unit gives standard IP 192.168.88.1
I can ping that.
If I enable DHCP server on my laptop, RB2011 receives IP fine. I can ping on that too.
I receive MAC properly in DHCP-server-log.

On the display it mentions ether1-gateway, link-ok- negotiation done

in terminal (OSX):
telnet 192.168.1.24
Trying 192.168.1.24...

in terminal (OSX):
telnet admin@192.168.1.24
admin@192.168.1.24: No address associated with nodename

Maybe this also helps, a traceroute does not seem to reach te unit at the end.

I did expect to run into some problems, running wifi - extenders - and hotspot functions, but not at this stage connecting to it. I tried the back to factory defaults by display.

any help is appreciated

Adition: tested on windows 7, software could not find router

Check "/ip firewall filter". The RB2011 blocks WAN access by default. Add a rule that allows your remote ips through the firewall.

Interesting. On port 6 with IP set, I now can access the unit. This should get me started.

Have you read what is written on the box before running the router?

probably another point to re-write WinBox over Qt framework and make it cross-platform and add both "update RouterOS and firmware"and "reset config" check-boxes right aside login info entering fields.
p.s.
also ability to get printed manual for reasonable price could could be found handy by some newcomers.
or atleast (4-6x paged ?)booklet, covering basic/initial setup both thru webfig and telnet.
