Hi
I am having an issue with my newly purchased mAP 2n.
It was working fine for about 2-3 days.
Have tried resetting it using the reset button and also the screwdriver method at the bottom.
When i turn it on, i experience the following :
Anyone had/having this issue ?
Thanks in advance
Same Problem here.
Used it a few days.
Now no connection, no reset possible. NetInstall doesn’t work…
??
I have the same problem with my RBmAP2N
Yep.. exatly the same problem here. Just that it worked for 3 days 
Everyone tried Netinstall and connecting with MAC address? In that case, contact the seller for RMA procedure. We have not yet received any mAP devices for warranty repair, so it is hard to estimate what could be wrong, we would need to have at least one to look at.
I tried to netinstall it, but the device did not show up in the netinstall tool. We will return the router.
Hello,
here same Problem … after a time i think 5 days we reboot the map2n after that same led blinking procedure as described below …
no login, no ethernet, no netinstall, no booting … i think the map2n is bricked …
you have any idea to fix this problem ?!
best regards
Think I have similar problem. Router is at factory defaults, sometimes it works properly but sometimes it wont give out any ip, its not possible to connect by wlan and wifi signal jumps from -95 to about -60db all the time.
Any one solved this yet?
Mine is acting very strange. I can’t get a solid link light half the time, I was able to get in if I reboot it enough times, but after a downgrade to 6.25 after seeing kernel panic messages I was never able to get it to work again.
I guess I’ll mail it back.
Count me in as one of those with a blinking mAP 2n…
Mine only got to live for 5~10 days. 
Found out that my PC doesn’t connect to the device through Ether2 this morning, use wifi on mAP 2n to get connected and reboot the unit through Winbox.
The rest is like everyone else here: Blinking LED in the exact pattern, with no everything.
I purchase this so I could have the same ROS experience when I’m on business trip.
Only it’s now a $45 USD brick.
Or should I say I’m lucky it’s dead before the trip?
Now… Could I continue trusting that RB2011UiAS I bought the same time to replace my home router…!?
(Up and serving for about a month now)
@normis , mind give us some explanation?
same problem here…
after update to 6.28 needs to reboot…
after the reboot same failure… all leds on… usr led off… all leds off but power led on… a second later all leds on again..
i think the map2n is bugy
no reset works
and now ?
same problem here, tried to update to 6.28, rebooted, all leds blinking, no mac, no netinstall, no nothing.
Yes, on my device it was. Exactly when upgrading to 6.28
After that I was able to upload the new version using netinstall
My problems with freshly bought mAP-2n for testing:
A. Long time to be detected by WinBox
B. No access from Winbox to mAP with default config - via IP and via MAC
C. after few attempts netinstalled to 6.28 with “apply default config”
D. Somehow managed to connect
E. LEDs flashes during boot and are all off after boot. mAP seems to be bricked but it works…
F. I resolved the problem with LED. Default 6.28 settings for LEDs are miscofigured and you need to set up them to more resonable settings…one LED for one value
And the biggest problem:
G. Backup files vanish after reboot so there is no possibility to make backups.
Similar issues here. I’ve had my map2n for many months now, configured in AP bridge mode. All of a sudden yesterday, I lost connection to wifi. Sometimes i could connect but ping times would be poor or dropped both to the internet and to my gateway, which is a RB450G. From wired machines on the network, I could ping the map2n easily and without delay, and access the web config. Then suddenly, i could no longer access the web config and there were no SSIDs broadcast. I rebooted the device multiple times, and used both the reset button and the jumper several times. Finally i got a Mikrotik SSID and got back into the thing, configured a wired connection and downloaded firmware to the latest, 6.28. It was at this point that i thought i bricked it because the LEDs stopped working except the power led. After a few reboots and resets i got back into it via the wifi again, and found the setting to re-enable the LEDs. Still, spotty ability to connect to the SSID, it disappears and comes back sometimes after rebooting, sometimes not.
At this point i’ve given up on it, and ordered 2 of the new hap’s which are due to be coming out soon. In the meantime ill try to find some old ap to make work until then.
Mine is not…
Then how did you manage to set up it?.. Never seen that too, though.
It’s a feature of mAP. You need to save all files you will need after reboot to the “flash” folder. For example, you need to write backup file name as “flash/backup”, and it will be available after reboot.
Patience and netinstall
I have processed, configured, and placed about a dozen mAPs in the past several months with no issues. Today, four more arrived, and none of them would netinstall, no way, nohow. I even had trouble getting them to show up in Winbox (both 3 and 2) until I moved the cable to port 2 and let it boot without using any of the special initialization buttons.
These units were shipped with ROS 6.23 in them. The “current firmware” in the units was 3.22, but the “upgrade” firmware (in ROS 6.23, I assume) showed as 3.17, which was just wrong. If you attempted to run a firmware upgrade (which my stock initialization macro does as a matter of course), you received, “cannot change firmware to this version.”
Since none of them would netinstall, I had to upgrade the ROS by hand to 6.29.1 (the version that is available right now) to replace the underwater firmware, then reboot. After that, the firmware versions matched.
However, the units still will not netboot. Holding the side button until both USR and CAP/AP stop blinking does nothing – the unit shows up in Winbox booted normally instead of in Netinstall. Setting the Routerboard settings to “Try ethernet once then NAND” and rebooting has exactly the same result. These are the first mAPs that have ever given me this problem.
There is nothing wrong with my netboot setup – I can unplug the cable out of any of these faulty mAP units and plug it directly into an SXT with the button held down, and it shows up in the netboot window first time, every time.
All the evidence suggests to me that something is very wrong with the firmware in this particular batch of mAPs. At least I hope it is firmware and not hardware, because I would hate to deploy mAPs in the field on which I could never hope to run a successful netinstall in the future.
Hi,
I had similar with my mAP 2n issue after
system package update upgrade
:
After upgrading the mAP stuck while rebooting with LEDs lighting on: PWR, AP/CAP, Wireless, ETH2, ETH1.
Re-powering instantly showed this LEDs and no communication via mac-telnet or Winbox.
I had to reflash the ROS via NetBoot to get the mAP 2n working again (pressing the RESET-Button until USR-LED got off).
This is no a good sign for future ROS-updates in field… 
I was told by your support to RMA my four. Unfortunately, two have already been placed (they go like hotcakes) and I believe another is committed. I will RMA the remaining one for you guys to examine.
