I did that. :--> I have tried every reset procedure I can find on the net, for example 30:30:30 but what I really need is a specific reset procedure that explains how long each step takes as there are MANY reset procedures for the RB411. There's the shorting point where you stick a screwdriver for an unspecified number of seconds while powering up and then you wait for an unspecified set of unspecified color LEDs to light up, and there is the spring-loaded reset button which you press for an equally unspecified period of time while already booted and then you wait for an unspecified set of unspecified color LEDs to do whatever it is that they do. There's also that beep I keep hearing which I don't know what it means. I've been trying everything, for example I tried to connect to the MAC address (which I had written down so I know what it is) of the LAN and WAN on the routerboard RB411 last night using Winbox.exe version 3.37. winbox.exe 192.168.88.1 admin "" winbox.exe 84:1B:5E:AF:BF:CF admin "" I also tried the webfig interface of the RouterBoard RB411 on port 80. http://192.168.88.1/webfig/ I wasn't sure if it matter whether I used the 32-bit or 64-bit winbox version 3.37 so I tried both of them but got the same negative results. At this point I don't care which RouterOS I boot it to as the MikroTik RB411 (like all MikroTik router boards) has a duplicate OS inside it. (I think that's what the Phillips head shorting point is all about.) And I don't care what settings it resets to just as long as I can log into it from Windows on the same subnet (presumably the 192.168.88.xxx subnet). netsh interface ipv4 show config netsh interface ipv4 show config "MyEthernet" netsh interface ipv4 set address name="MyEthernet" static 192.168.88.2 255.255.255.0 192.168.88.1 ping 192.168.88.1 -t None of this works so I think the router is in some stuck state, although it boots up (seemingly) with lights lighting up and blinking at times (blue and green LEDs) and it beeps too. I just need a definitive specific explicit reference for the MikroTik routerboard RB411 with RouterOS on it for how to reset it to a state that I can then connect to the RouterOS on it to set it up as a CPE Access Point. I tried the MikroTik forum but it never sent the confirmation registration mail so I don't think it's still supported as it seems to be dead a while. https://forum.mikrotik.com/viewtopic.php?p=438256 https://forum.mikrotik.com/viewtopic.php?p=454673 https://help.mikrotik.com/docs/display/ROS/Reset+Button https://mikrotik.com/product/RB411 https://www.mikrotik-store.eu/en/MikroTik-RouterBOARD-RB411 https://forum.routerboard.com/viewtopic.php?t=156670 I'll put openwrt on it if I have to but I still need to connect first. https://openwrt.org/toh/mikrotik/rb411 Most of the descriptions aren't specific enough to actually work. https://www.youtube.com/watch?v=OD708qX23eM How to HARD RESET MikroTik RouterBOARD RB411 I will try anything because all I want to do is connect to it. -- Cheers, Rob |

Run a port scanner (e.g. nmap) on the entire 192.168.0.0/16 subnet. Then try the 10.0.0.0/24 subnet if you don't get a hit on 192.168.0.0/16 |

Do I need to put the Windows PC on the same subnet as the RB411 might be? Anyway, I googled for nmap and somehow I ended up with Zenmap on my desktop. https://nmap.org/book/zenmap.html The default zenmap scan is apparently this command. Target: 192.168.1.1/24 Command: nmap -T4 -A -v 192.168.1.1/24 Target: 192.168.88.1/24 Command: nmap -T4 -A -v 192.168.88.1/24 The first nmap command it ran from the Zenmap GUI without the RB411 was Nmap scan report for 192.168.1.0 [host down] Nmap scan report for 192.168.1.2 [host down] Nmap scan report for 192.168.1.3 [host down] ... Discovered open port 443/tcp on 192.168.1.100 Discovered open port 443/tcp on 192.168.1.101 Discovered open port 443/tcp on 192.168.1.102 There were pages of results, so I'm weeding through them first while I'm on my home LAN before I connect the PC directly to the RB411 router. It's a pain not knowing what subnet to put the PC on so I pulled the Ethernet out of the home router and plugged it into the RB411 instead. Then I changed the PC IP address to these two one by one. Win+r cmd {control+shift+enter} netsh interface ipv4 show config netsh interface ipv4 show config "Ethernet" netsh interface ipv4 set address name="Ethernet" static 192.168.1.2 255.255.255.0 192.168.1.1 ping 192.168.1.1 -t (which fails) Then I ran the zenmap GUI with a Target: 192.168.1.1 192.168.1.255 Command: nmap -T4 -A -v 192.168.1.1/24 setup_target: failed to determine route to 192.168.1.0 setup_target: failed to determine route to 192.168.1.1 setup_target: failed to determine route to 192.168.1.2 ... Then I tried the 88 subnet. Win+r cmd {control+shift+enter} netsh interface ipv4 show config netsh interface ipv4 show config "Ethernet" netsh interface ipv4 set address name="Ethernet" static 192.168.88.2 255.255.255.0 192.168.88.1 ping 192.168.88.1 -t (which fails) Then I ran the zenmap GUI with a Target: 192.168.88.1 192.168.88.255 Command: nmap -T4 -A -v 192.168.88.1/24 setup_target: failed to determine route to 192.168.88.0 setup_target: failed to determine route to 192.168.88.1 get_srcaddr: can't connect socket: A socket operation was attempted to an unreachable host. setup_target: failed to determine route to 192.168.88.3 setup_target: failed to determine route to 192.168.88.4 setup_target: failed to determine route to 192.168.88.5 ... I'm not sure what I'm doing, but it seems I get different results if I put the PC on 192.168.1.xxx versus 192.168.88.xxx and then I run that zenmap port scan - but I don't yet know what to make of the results since nothing came back as a really good hit. My googling found also "ipscan" and "portscanner" which I may try. https://angryip.org/download/#windows https://www.eusing.com/ipscan/free_ip_scanner.htm https://www.advanced-ip-scanner.com/download/ The problem is that the search is filled with shills so I don't know which is the right freeware respected ipscanner or port scanner download. Given the syntax is not in the least intuitive (it takes experimentation), does anyone have a recommendation as to which scanner to concentrate on? -- Cheers, Rob |
