If your GPS says “turn left here” but on your left is only the river … do you take the turn ?
I hope not.
Sometimes we have to think and adapt based on what is available and what needs to be done.
Show EXACTLY which netinstall guide you are following.
Which packages (list EXACT name and extension) are you trying to feed into it ?
The manual says, I have to find the switchport where netinstall will run. Sometimes it’s this port, sometimes another. I just try to figure out which one is the best port here…
The manual says, often it’s labeled “boot”. Not here. I have to “think myself”. Aka “try myself”…
What you have made clear about yourself is sufficient.
I’m sorry, but before I get banned for what I could answer you, I better stop writing on this topic.
Addendum: Exact words
https://help.mikrotik.com/docs/display/ROS/Netinstall#Netinstall-Introduction
In short, the Netinstall procedure goes like this: Connect your PC directly to the boot port (> Usually Ether1> , the port labeled BOOT or as otherwise indicated in the product manual) of the device you will be reinstalling.
MikroTik devices are able to use Netinstall from their first port (> Ether1> ), or from the port marked with “BOOT”.
nothing is labeled boot. And booting from ETH1 doesn't show the device in netinstall.
I tried that 3 times now, the last time I hold the button several minutes, as the manual says "hole button until the device shows up"... but there's nothing coming up.
And I know, Port 1 is on the left, lower row 
I wouldn't have any problem with that it's far from what I think about the troubles I have with this "situation"... Day 3 just to get a DHCP working ... finding out that an upgrade is not useful, hearing that there was a bug, making the experience that netinstall isn't working at all,... Believe me, I'd rather throw those pieces into the recycle bin and buy something "easy" ... a Cisco ASA 5508, a Catalyst 2960X,... I manage those devices for a decade now and never had troubles with firmware or manuals... By now I wanted to learn something new, and my hope was to save money...
Boy that went south. Anyway.
I just do NOT see netinstall as being particular important here. If you want to use it, it’s easier to from Linux IMO, since there’s just less steps in setup.
If you used QuickSet originally to set the IP on the factory version — that could cause the 0.0.0.0 dhcp network — which is a terrible bug if your new (and someone likely would be… if there using QuickSet since that make sense to start). And unlikely cisco, RouterOS is way more relational in the configuration – so a “DHCP server” is made up of 3+ different config lines, in different places. And this make it difficult since you might focus only on the /ip/dhcp-server one (and not think there is “dhcp-server network”, which is more like dhcp profile). Etc.
But is anything not working here?
e.g. if it just resetting the configuration, you can use the reset button.
That’s only tricky since take a combo: powering unit off, depress the reset button/pin-hole for ~7 seconds (until “User” light flashes) AND powering on the unit at same time as holding. See https://help.mikrotik.com/docs/display/ROS/Reset+Button – they don’t mention the time, but it more than 5 second and less than 10 to reset to default configuration.
Since you’ve already upgraded to 7.13, it will have the more recent default configuration (e.g. the default config changes with the version – but only used if you do an explicit reset-configuration). I suspect you’ll be able to set the IP address, DHCP server range, etc. using winbox app (you can use the web page, but best if you just use the winbox app on desktop)
less? I need to buy a new computer to install linux, after finding the right distribution, and a way to boot it,… This is everything else than less work for someone who has no linux computer on hand. But I know exactly what you mean. If I had linux PC, I’d use it.
Reset doesn’t work. The cars has the same config as before. Tried a hundred times now…
Same for the access points…
And following the guide the crs112 show boot into netinstall setup. It doesn’t. After power cycling with pressed reset-button the switch starts normally with “my” last config (not the basic config).
There is one other thing I am wondering here …
CRS112 is a MIPSBE device having only 16Mb storage.
Can it digest 7.13 ? Might be better to stick with maximum 7.12-version (it’s smaller, not much but maybe enough to keep it stable).
Netinstall:
can you place a dumb switch in between ? It sometimes helps.
Since you use Windows, are you sure ALL network interfaces except that one ethernet port are disabled ?
If you see it has your config, you can also reset it from Winbox.
System / reset configuration
Tick Keep users and Do Not Backup
Untick Caps mode / No Default Configuration
Hit “Reset configuration”
I bought the device because I wanted to have the features that mikrotik adverts. Some are only available with 7.13
And then the crs112 won’t run that? Shall I destroy it and buy the biggest flagship mikrotik offers? just to get a DCHP server running and to access points managed?
Sorry, but then I will have a look back on Cisco. Their devices are ready to use the software they develop…
I never have dumb switched. So no, not at this moment.
Yes, I’m sure that wifi is off. It’s the only network IF besides eth.
In theory, yes. And seems able to get to the configuration, it’s working.
On the CRS112, if you can get to the configuration, then you can use System > Reset Configuration. You may want to check “Do Not Backup” and also check “Keep Users”. This will get you back to WAN on ether1, LAN on ether2-8 configuration with the default IP 192.168.88.1
System / reset configuration
After attempt #194 reset worked. Could cry… the whole config is gone… (I knew that, but seeing it is really bad) 2 days of work getting those access points running.
To be honest, that demotivates me. After 3 full days I only can reset that damn thing, do the same sh* again and I know I will end up with the same problems, the same situation.
Because we didn’t change anything here 
I’ll have to decide if I give it a second try or if I will send the 400 euro into the recycle bin.
DHCP is just one problem.. there’s no, absolutely NO performance with wifi… out of the box 50mbit to the local lan.
@mikrotik: this is not fair! My cisco Ads from 10 years ago don’t need wifi 5 or 6, they deliver 1300 MBit out of the box, Clustering (management of 6 APs!!) is ONE CLICK! Exactly one click!
Including roaming without interruption …
They same goal with mikrotik will cost me years, if everything runs as smooth as this … stuff.
no WAN on eth1. Empty. Everything.
You definitely got off on the wrong track but for what it is worth in general there is nothing wrong with MT devices.
A steep learning curve, definitely !! Still learning new things at least a week myself.
As for wifi performance: those cap ACs (if properly configured) can reach 400Mbps in a interference-free environment.
Using wave2 drivers it can go close to 700.
But FIRST we need to get that CRS functional.
So I suggest we do that.
How is your WAN port connected to ISP modem ?
Simple ethernet ? PPPoE ?
Can you open terminal and use
/export file=anynameyouwish
Move file to PC
Edit and remove serial number

- The CRS112-8P-4S is a PoE switch, not a router.
- There is a total lack of professionalism in the user’s speeches which makes me believe he is here to act as a troll,
rather than actually wanting help. He took this forum as one vent because he doesn’t know the product. - The device costs me less new than what is written on the MikroTik site (~$200), so how he can pay €400 for it is a mystery.
It can be used as a router. Low performance, yes and it will perform a lot better as a switch, but it can be done.
