it does not matter in which order you will connect them.

nordex

could it be bridge loop protection ?
either from cisco or mikrotik side.
can you put switch between them so you can debug from which side port flap occurs ?

nordex

DO NOT upgrade it on 2011.
Bricked one from 43 to 43.2., me too.
Remote destination...tommorow will be looong day.

nordex

So why you have not upgraded first to 6.40.7 (bugfix) with old bridge implementation?
Why are you upgraded working hotel infrastructure to RC version? RC is test version so upgrade could fail.

It was a sunny and beautiful day. Murphey was out of the town.

BartoszP, this site(hotel) has 200 ap-s dislocated on premises. I have done previous upgrades from 5.x to 6.x without problems. This particular release has bug in upgrade procedure. Routerboard stuck in reboot loop. It does not have any relation with changelog. Netinstall to version 6.42 works fine....

nordex

Hi, thanks for your simphaty. I've tested it on device that had 6.0 prior to this and I saw it fixed wifi problem. I was so happy. Then I upgraded others(batch upgrade), and this problem happened. I understand this is RC, and I wanted to warn others not to do same mistake, as well as mikrotik to fix...

nordex

BEWARE !
Updating from 5.xx (5.27 I think) to this version will result in inaccessible device ! It will enter reboot loop.
I've done it on 15 pcs of rb751 and rb951-2n.
Netinstall will fix if you mess up.

Mikrotik please update your upgrade procedures

nordex

Ok, CCQ is better.
What about speed difference? Noticeable or not?

nordex

It is probably your OS firewall that is preventing share services to be used from non local subnet.
For the test, disable your OS firewall and check again.

Got my WAP LTE kit today. both has loose heatsink. Luckily I inspected mine before powering it up. the heatsink is rubbing against solder, parts and antenna. pretty sure it will cause overheating or short. We haven't seen similar reports, can you please send us the serial numbers of these units to ...

https://forum.mikrotik.com/viewtopic.php?f=7&t=102908 Most of mikrotik wifi devices (90%) suffer the same problem and Mikrotik lies about it and does nothing to fix it. Access points are not able to utilize full wifi speed on 2.4ghz with most of mobile phones (except high-end models). Phones get lo...

nordex

Heh, wait until you find out that you are unable to surf on that device with full WiFi speed
on 2.4 ghz

nordex

I vote that we make new forum topic with alert to all new buyers informing them that mikrotik does not work correctly in 2.4ghz spectrum.
And with regular bumping we should keep it on top of forum.

nordex

Any reason to go for this over the WAP-LTE Kit ? maybe for three common reasons: 1. device overheating problem (passive cooler falls off) 2. sometimes missing lte interface 3. need for constant reboot to reconnect (automatically with scripts) the device is premature, I believe that this shortage of...

Mikrotik is everywhere.
Should ISIS start complaining about bad WIFI so Mikrotik finally hears its customers ?

The issue is mostly on 2.4ghz and 54mbit max rate and it is software bug (installing openwrt or LEDE, and it works full speed)
Normis, please respond to what users ask from Mikrotik.

This is a HIGH-level issue.
When will this be fixed?

nordex

@honzam - tnx, but then I loose wireless controller, and openwisp controller looks bit complicated @jarda - I really did not think of you, old forum veteran, to give this kind of answer. It's not about notebook issue, read my post again. Only connection from mobile phones are affected. Please don't ...

nordex

Sorry, I must have overreacted because of frustration. Here are some facts: I follow and use Mikrotik since version 2.9.27. That is long. It's not about 200 devices and interference. Take only one mikrotik wifi AP 2.4ghz in absolutely clean wireless area. Take 10 different mobile phones. Do a speed ...

nordex

Ok, let me put it this way. Take one RB, connect it to 2.4ghz, clean surrounding. Try speedtest with 5-6 different mobile phones. Do you get more then 22mbit on all of them ? I bet some of them will have tx rate 54 mbit max on wireless registration tab. THAT is the issue. Mikrotik does not work well...

Hello, I'm seeing speed issues in wireless, 2.4ghz, download direction. Upload works better then download . Download gets 20 mbit, upload goes full. Issue is with mobile phones(most of them, only high end are ok, but its only 25% of them). Laptops seems to work fine. Yes, I've read forum about this....

nordex

Hi, Yes I did notice somewhat more heat then usual. Passive cooler was so warm that glue melted from chipset and cooler fell off. Sim Location and insertion and removal process is painfull. Mikrotik staff, you should have team of product Beta testers which will return objective Feedback info to you ...

what RF elements antenna model would you recommend for ptp ?
except this one which is yet to come.

and which mikrotik board.

nordex

So QRT is better in noise area. ok.
Have you tried to test qrt/dyna vs netmetal+other anntena in same conditions ?
Does rf elements antenna show noticeable performance upgrade vs qrt/dyna.

Hello, can someone please write differences between QRT 5ac and DynaDish 5ac. What are practical differences between them (ignoring license, mounting and size). What are practical advantages/diferences of one over other one. Why is qrt more expensive ? Does it have better antenna for PtMP ? back sid...

I keep getting this loop detection message on EOIP when OSPF annoucments goes through.
I've disabled loop protection but with no success.

Anyone else getting this ?

Hello, I would like to report missing interface on WAP LTE. It was working for 10 days, but with often disconnections. I've set up script to monitor interface status and reboot if it was offline. Now, there is no LTE interface at all. I have tried to install latest rc version and lte package as well...

ok, 50% is 3hrs.

Hi, mUPS sounds interesting. Is it possible to power possibly a PowerBox at which probably 4 wireless systems are connected wit PoE? So is it possible to power 5 routerboards at the same time with one mUPS? Or is the current output limited anyway? 2A current (at 24V) should be ok for this constella...

nordex

1. have you wide knowledge on wireless ? 2. have you been using mikrotik before ? 3. do you have time to buy smaller amount of equipment and test before ? 4. 1200 clients is A LOT ! Things will go smooth with 30-40 clients, but 1200 is a freaking lot. 5. reduce output power on AP in order to force r...

nordex

when you disable/enable interface it will run channel select procedure.

nordex

If someone has stolen your sxt but it's still connected, And other AP is in bridge (not AP bridge) mode then you will see the network but will not be able to connect. Change your encryption keys.

nordex

This should be reported sa bug. Please send it to support@mikrotik.com

nordex

normis,
switch to manufacturer driver when scanning spectrum, and then switch back

nordex

Add temperature/voltage graph.
I know it is possible to add it on dude/snmp monitoring, but sometimes it's complicated, and it should not be big problem for you to add it to the existing graphing routines.
Thanks

nordex

ok.
Then maybe info like

max charging current
max output current
12/24V ?

nordex

don't use it,
known hardware bugs,
EOL
use 951 instead

nordex

I see that you are using 3 chains.
What antenna exactly do you use ?

nordex

Maybe, just maybe:
What is your wireless configuration?
What type od bridge is it?

Maybe your mac address got changed(cloned) when drone roamed to another AP And that confused arduino or PC?
Can you try to delete Arp table while you are on a second AP.

Maybe spanning tree ?

Does three polarity antenna even exists for point-to-point links ?

Hello, can someone explain practical difference between 2 and 3 chain versions of NetMetal 5 for point-to-point links ? For what antenna is that ?

For future reference, it would be nice of you to write down here settings that you have tweaked so other members could find it in the future.
