Got a new 532A with a Senaro card in it. Configured it all up with dhcp server, pppoe, pptp. Then at the end I clicked enable on the WLAN card, took about 3 seconds and then powered off the board. Now it just keeps reseting until I take the WLAN card out. When I put it back in, it keeps resetting. HELP!!!

Welcome to the wild, wild world of xMP-8602 cards! (it is a 8602, not a 2511, right?)

Often, it seems, this little bit of joy is related to transmit power levels. If you adjusted the TX-power, that was likely your downfall. If not, you may need to do so (downward!).

To get things stable enough to adjust settings, you need to be quick. There is usually a window of a few seconds after it boots up before it reboots, that's your chance:

You will want to have a nice minimalist disable command ready and waiting on your clipboard, something like: (Be sure to have the newline copied as well, you don't want to have to hit return after the paste, every millisecond counts!)

As soon as it boots up, quickly log in, and paste that command in. With luck it won't reboot.

Otherwise, pull the card, boot it up, do a /system reset, re-install the card, and start from scratch (being very careful about power). Or, just replace the card (perhaps with a CM9 or R52).

It also seems, perhaps sometimes (maybe), to be triggered by having too weak a power supply. If you are using a wimpy power supply, replacing that with something beefier may help.

Good luck,

Ok, set all tx levels to 23dbm, working now. Is that the correct setting? Also is this card junk? Because i will be replacing an already functioning AP with it. and BTW is one 532A enough jam to run about 25 wifi customers while uning ether2 for pppoe to another AP and doing NAT?

Correct is in the eye of the beholder, so to speak. 23dBm should be safe, though.

I wouldn't call them junk, but they are touchy little sobs. I've got dozens running just fine, in one case four of them in a single RB532 (with multi-month uptime). Once you have things tweaked and stable, it should be fine. Just be sure to think twice before adjusting the power once it's working, it really sucks when they start doing this in the field.

As for the 532's capacity, it's probably plenty.

Had the same problem on about 7 EMP/NMP-8602+
Router would reboot about 3-10s after booting up.
After much testing the problem was found only to occur when the cards were set to 5Ghz and enabled.
I program all my units via script, and I found I was enabling the wireless interface before actually programming them. The default setting that RouterOS sets the NMP/EMP-8602+ to is 5Ghz. So when my script started to run it turned the card on and 3s later it rebooted. I adjusted my script to leave the cards disabled until after I set them to 2.4ghz, and now the units have been running for 3 months.

I have repeated this on the bench with numerous RB532s and EMP/NMP-8602+, not all cards to this, and it doesn't seem to occur in RB112s. Power is not an issue I've tried various PoE sources, and TX settings, to not avail.

This is still a problem I don't know why some cards work and some don't, but since I only use SR5s for 5Ghz I was not too concerned as long as they operate stable at 2.4Ghz.

Any word from support on this issue? I had it happen with a unit running 2.9.4, but when I upgraded to 2.9.27 it fixed itself.

if i get this problem i just put the problem card into an rb112 or wrap 2c and reset it's settings back to default TX power and then put it back in the rb532. that stops the endless reboots


there is a big problem on the 532 end that mikrotik will not admit when it comes to 8602 cards..... its ONLY on the 532
