Maybe a dumb suggestion, but do you have neighbour discovery turned on? I wonder if it's using the Tik version of CDP to go detect port capabilities, and ignoring your settings? On 16 October 2015 at 08:54, Paul Julian <paul@oxygennetworks.com.au> wrote:

HI Damien, sometimes yes, sometimes no.

For example, the one I just had has been running perfectly for nearly 2 years plugged into a RB2011, the Omnitik was hard set for 100M FULL and worked fine. We swapped out the RB2011 for an RB1100AHx2 as it was running out of puff on the site, then we couldn't get the Omnitik to connect up in full duplex again, no matter what we did, then I changed the Omnitik to Auto Neg and the RB1100 to Auto Neg and they are happy, there just doesn't seem to be any consistent setting that works with Omnitiks....

Does a reboot fix it? If so, is it worth using a scheduled script to test it every 10 minutes and reboot the device if it sees it in half-duplex?

Hi Mike, I have only just seen it on ether1, I suppose that's because that's mostly the port I connect to on them, it doesn't matter what connects, even a laptop can do it if you are unlucky, so it's not even Mikrotik to Mikrotik only, it's anything.

Changing from auto to hard set on the Omnitik doesn't help, the last one was hard set to 100 Full, but when connecting it to the new RB1100 in Auto mode it just wouldn't sync up right, even changing the 1100 to hard set 100 full it still wouldn't sync up right, there is something definitely wrong with those Omnitiks I reckon.

Maybe I'm just lucky......but I needed to set both the Omnitik and RB1100 both to Auto for it to work, but having the previous RB2011 in Auto and Omnitik in Auto wouldn't work in this case.

Hi Paul,

That's not to say it doesn't happen, just that I haven't heard about it.

I don't remember all the checks we did last time, but does it happen on all ports, or just the PoE out (or in)? Is it always the same kind of devoice at the other end that shows this behaviour, or does it happen regardless of what other device is on the other end? Can you stop it from happening by disabling the auto-negotiate?

For any outdoor units I ditch the standard floating power supply and use the 24POW30 as it connects the negative power (ground) to the actual earth in the power socket. This lets me follow as close as possible the recommendations by Mikrotik and Ubiquiti for grounding external units without getting into using fiddly earth leads and shielded network cable. I have also put together my own patch arrangement with keystone blocks where 2 external units on a mast are linked over ethernet but also share a single power cable from a 24POW30. This arrangement fits nicely in a small weatherproof PVC box on the mast. So far everything running off the 24POW30 works just dandy - the longest being almost 2 years now. So, in the absence of any other solutions apart from replacement try feeding off a single 24POW30. On 18 October 2015 at 11:33, Paul Julian <paul@oxygennetworks.com.au> wrote:

Hi Jason, perhaps I'm the only one having the issues but I have them at totally different sites so it's not just at one place, again yesterday I had another issue at one of the sites I often see the problem at.

I have 5 omnitiks at that site which form a backhaul network which then have 2.4G AP's hanging off each except the backhaul AP router.

One in particular has been a problem for a long time, all of them are setup identically though. This one dropped out yesterday, again, when I say dropped out I mean I couldn't see the 2.4G AP which was plugged into ether1 on the Omnitik, I could see that the interface was running and connected but could not talk to the RB411 AP, it appeared in neighbour list though.

When it does this sometimes the link shows as 10M half duplex, other times it shows OK as 100M full duplex. I rebooted the Omnitik and then I could get to the 411, nothing else changed. So I upgraded to the latest ROS version and Firmware version on both units, rebooted everything one more time for good measure and it was all good.

Then about 2 hours later I got an alert saying the AP was down, I connected into the backhaul router and the interface was now 10M full duplex, previously it had correctly negotiated at 100M full duplex.

So now the AP is still down, so everything is running the latest of everything and still a problem.

I don't know if it's something to do with POE or just the Omnitik in general, I have plenty out there which don't do this, or haven't done it yet, so I am baffled but these ones, the only thing I do at this site which is a bit different is that I run two POE injectors which face away from each other to power the RB411 and the Omnitik, then a patch lead between the injectors to connect them together, I really can't see any issue with this as the power is only coming out the end where the radio plugs in, there really shouldn't be any problem with that scenario, but the other one I had issues with earlier in the week had nothing like this, just a straight POE connection and then into a RB1100AHx2 on the end of it.

I wouldn't say don't buy them because of this, nobody else seems to be having the issue that has responded anyway, but the Omnitik isn't a bad radio as long as you don't want low noise :-) a sector is always a better option if you can do it.

Interesting idea Jason, thanks for the information.

I had an interesting turn of events today, yet another site had issues, this time we started getting customer complaints about speed to one of our wireless POP's, radio speed was up at 130M and signal very good, but customers only getting 8.5 or 9Mbit's on download and upload tests even though they were on higher plans.

Upon investigating we found that the SXT at that site was synced to the router it connects into at only 10M full. Both devices, the SXT and RB2011 are configured for auto negotiation and to advertise all speeds and duplex options, however they are both claiming that the other device is only advertising 10M FULL and 10M HALF and that they themselves are only advertising 10M FULL and 10M HALF, what the ???

They are both set to auto negotiate, how on earth can they claim to be only advertising 10M and only seeing the other device advertising 10M, crazy stuff indeed.

Time for a ROS upgrade and firmware upgrade for these two as well, looks like the problem is no just Omnitik's now !!

The only thing that is common with all of these devices is that at least one of them is powered by a POE injector or POE feed from the router (as per the one today).

Hi Have you been able to resolve anything. The Omnitik I installed this week has not presented this issue. It is only using port 1 and is powered by a 759UP. Jason Hecker On Oct 20, 2015 2:58 PM, "Paul Julian" <paul@oxygennetworks.com.au> wrote:

HI Jason, I haven't tried replacing cables as yet, the site I have most problems at is a couple of years old, but all joins are inside houses, still, there could be an issue there. The site yesterday has connections in the MDF room, so should be good also.

The one thing which seems common here is they all have POE injectors, I can't help but think perhaps there was/is an issue with the Mikrotik POE injectors intermittently, I think they are all the beige ones which don't do gigabit from memory.

I had an interesting turn of events today, yet another site had issues, this time we started getting customer complaints about speed to one of our wireless POP's, radio speed was up at 130M and signal very good, but customers only getting 8.5 or 9Mbit's on download and upload tests even though they were on higher plans.

Upon investigating we found that the SXT at that site was synced to the router it connects into at only 10M full. Both devices, the SXT and RB2011 are configured for auto negotiation and to advertise all speeds and duplex options, however they are both claiming that the other device is only advertising 10M FULL and 10M HALF and that they themselves are only advertising 10M FULL and 10M HALF, what the ???

They are both set to auto negotiate, how on earth can they claim to be only advertising 10M and only seeing the other device advertising 10M, crazy stuff indeed.

Time for a ROS upgrade and firmware upgrade for these two as well, looks like the problem is no just Omnitik's now !!

The only thing that is common with all of these devices is that at least one of them is powered by a POE injector or POE feed from the router (as per the one today).

For any outdoor units I ditch the standard floating power supply and use the 24POW30 as it connects the negative power (ground) to the actual earth in the power socket. This lets me follow as close as possible the recommendations by Mikrotik and Ubiquiti for grounding external units without getting into using fiddly earth leads and shielded network cable.

I have also put together my own patch arrangement with keystone blocks where 2 external units on a mast are linked over ethernet but also share a single power cable from a 24POW30. This arrangement fits nicely in a small weatherproof PVC box on the mast. So far everything running off the 24POW30 works just dandy - the longest being almost 2 years now.

So, in the absence of any other solutions apart from replacement try feeding off a single 24POW30.

Hi Jason, perhaps I'm the only one having the issues but I have them at totally different sites so it's not just at one place, again yesterday I had another issue at one of the sites I often see the problem at.

I have 5 omnitiks at that site which form a backhaul network which then have 2.4G AP's hanging off each except the backhaul AP router.

One in particular has been a problem for a long time, all of them are setup identically though. This one dropped out yesterday, again, when I say dropped out I mean I couldn't see the 2.4G AP which was plugged into ether1 on the Omnitik, I could see that the interface was running and connected but could not talk to the RB411 AP, it appeared in neighbour list though.

When it does this sometimes the link shows as 10M half duplex, other times it shows OK as 100M full duplex. I rebooted the Omnitik and then I could get to the 411, nothing else changed. So I upgraded to the latest ROS version and Firmware version on both units, rebooted everything one more time for good measure and it was all good.

Then about 2 hours later I got an alert saying the AP was down, I connected into the backhaul router and the interface was now 10M full duplex, previously it had correctly negotiated at 100M full duplex.

So now the AP is still down, so everything is running the latest of everything and still a problem.

I don't know if it's something to do with POE or just the Omnitik in general, I have plenty out there which don't do this, or haven't done it yet, so I am baffled but these ones, the only thing I do at this site which is a bit different is that I run two POE injectors which face away from each other to power the RB411 and the Omnitik, then a patch lead between the injectors to connect them together, I really can't see any issue with this as the power is only coming out the end where the radio plugs in, there really shouldn't be any problem with that scenario, but the other one I had issues with earlier in the week had nothing like this, just a straight POE connection and then into a RB1100AHx2 on the end of it.

I wouldn't say don't buy them because of this, nobody else seems to be having the issue that has responded anyway, but the Omnitik isn't a bad radio as long as you don't want low noise :-) a sector is always a better option if you can do it.

Hi Paul,

I am interested as I have only used one Omnitik in the past without these issues but will probably get another in the next week or so. If I get another one I'll give it a right seeing to in order to replicate your issue. It's going up very high and I don't want no trouble.

Hi Mike, I have only just seen it on ether1, I suppose that's because that's mostly the port I connect to on them, it doesn't matter what connects, even a laptop can do it if you are unlucky, so it's not even Mikrotik to Mikrotik only, it's anything.

Changing from auto to hard set on the Omnitik doesn't help, the last one was hard set to 100 Full, but when connecting it to the new RB1100 in Auto mode it just wouldn't sync up right, even changing the 1100 to hard set 100 full it still wouldn't sync up right, there is something definitely wrong with those Omnitiks I reckon.

Maybe I'm just lucky......but I needed to set both the Omnitik and RB1100 both to Auto for it to work, but having the previous RB2011 in Auto and Omnitik in Auto wouldn't work in this case.

Hi Paul,

I haven't heard it reported before, other than yourself :-}

That's not to say it doesn't happen, just that I haven't heard about it.

I don't remember all the checks we did last time, but does it happen on all ports, or just the PoE out (or in)? Is it always the same kind of devoice at the other end that shows this behaviour, or does it happen regardless of what other device is on the other end? Can you stop it from happening by disabling the auto-negotiate?

Cheers Mike.

Hi guys, a while back I asked the list about the issues we seem to have with Omnitik 5Hnd units and them randomly syncing up in half-duplex 10M, I have exhausted all options with these and after just having yet another one do it I am at my wits end.

It doesn't seem to matter whether you use auto-negotiate or try and hard set the interface speed on the device itself or the device that plus into it but they just randomly decide to go to 10M half-duplex, has anybody else seen this and come up with a concrete fix by any chance ? It only happens on Omnitiks and it seems that it's only on the ether1 port from what I can see.

I was at the site the other day where I plugged in an Omnitik to my laptop. In either Windows or Linux on my laptop port 1 of the Omnitik fed by a PoE splitter just would not maintain an ethernet link at all - it'd come up and fall over right away. It's been fine plugged into a 3rd party hotspot gateway device with a 10/100 port for 2 years. I didn't have time to investigate further but it was interesting to say the least. My laptop chip is: Qualcomm Atheros AR8151 v1.0 Gigabit Ethernet (rev c0) On 28 October 2015 at 16:43, Paul Julian <paul@oxygennetworks.com.au> wrote:

HI Jason, no I haven't resolved it yet, usually if I reboot enough times and muck about with it I can get it working, then at some stage in the future it will play up again.

I am probably replacing the wireless on that site soon so to be honest I'm not sure if I will spend much more time trying to resolve it unless I cop it from another site again like the other week

Hi

Have you been able to resolve anything. The Omnitik I installed this week has not presented this issue. It is only using port 1 and is powered by a 759UP.

HI Jason, I haven't tried replacing cables as yet, the site I have most problems at is a couple of years old, but all joins are inside houses, still, there could be an issue there. The site yesterday has connections in the MDF room, so should be good also.

The one thing which seems common here is they all have POE injectors, I can't help but think perhaps there was/is an issue with the Mikrotik POE injectors intermittently, I think they are all the beige ones which don't do gigabit from memory.

Hi Paul,

I suggested using a grounded supply to rule out any weird grounding and power issues. If you can retest your ethernet cables, you might even have a discontinuity or corrosion in the cable.
