Re: cAP ac / v6.40.4 - frequent disconnects?

Just an update that I upgraded the POE supply from 24v 0.5A to 48v 0.5A, and it's no longer disconnecting/re-booting.

Everything else seems to be working fine also, thx for suggestions!

Re: cAP ac / v6.40.4 - frequent disconnects?

While standards require quite low DC resistance of UTP cables and current of 0.5A through 30 feet of UTP cable should not cause too high voltage drop, use of sub-standard cables or non-perfect plugs and outlets or even oxidation could increase resistance of the PoE feed between ER-X and cAP ac to t...

Re: cAP ac / v6.40.4 - frequent disconnects?

Any suggestions how to trouble shoot this one?

Monday has rolled around & people are back in the house... After four days of no eth port disconnects on the cAP ac, it's again showing disconnects every 10-15 minutes (now that people are using it).

any hints? thx!

Re: cAP ac / v6.40.4 - frequent disconnects?

@anav, all I'm doing is checking the syslogs on the device to which the cAP ac is connected. It lists the interface (eth4) & times of disconnection & connection. Interestingly, there's no one in the house at the moment... and the logs are silent (it's constant for now). Last log was a "connected" pe...

Re: cAP ac / v6.40.4 - frequent disconnects?

To help eliminate potential problems, I upgraded to the latest firmware (v6.43.4).

Over the last two hours since then, the cAP ac has continued to disconnect & reconnect 10 times. It doesn't go down for long, usually 4-9seconds, but I would love to solve this issue.

cAP ac / v6.40.4 - frequent disconnects?

I have a cAP ac running on the POE of a ubiquiti ER-X, supply cable is Cat5e 30 feet...

Device is disconnecting from the network multiple times every hour (ER-X logs)

Any suggestions how to troubleshoot this?

Re: highest power dual band AP? [SOLVED]

much appreciated chechito,

Out of interest, do custom assembled routerboards play well together? i.e. are there many glitches (apart from rightly seating parts together) that one has to navigate (no offense meant... I'm used to building windows computers :-) ).

highest power dual band AP? [SOLVED]

Hi guys, I have a situation where one building would be best supplied by a higher power access point. Am I correct in thinking that the hAP ac currently is the highest power dual-band access point that Mikrotik produces?

Re: PoE Voltage Drops

For long cables or high consuming devices at the end I use dc converters. First creates 70v, injects into long cable by passive poe injector, extracted at the end and another dc step down converter to desired voltage is used between the extractor and the device.

You can see link modulations or plot ccq graphs, for example. Also voltage and temperature graphs together with cpu and memory utilisation graphs might help a lot. Very interesting indeed...

Hi Jarda, Hmmm, maybe I should have given more information. I estimate that only 30 or so clients will be connected at any one time... I don't mean to second guess your suggestion. Maybe let me check again, wouldn't a CRS125 be overkill? And to be clear, you're suggesting one access point per apartm...

The answer always depends on the local situation (not described), type of clients (not described), their behavior (not described), expected functionality - mainly throughput (not described) and other restrictions (not described).

8 apartments, separate SSID's for security?

Bear with me, as I'm new to RouterOS/Mikrotik. I currently serve WiFi to a block of 8 apartments. Access Point isolation is in place, so WiFi clients can't talk to each other, but I'm wondering whether I should separate this into 8 VAP's/SSID's to provide a higher level of security to each apartment...
