Jase2985:

Ive had a second occasion of my access points not passing any data from the clients to the rest of the network. The clients are connected fine to the SSID and i have great signal, but im unable to ping anything on the WIFI interface. On the Ethernet side everything works fine, can access the local webpage and configure it just nothing on the wifi side. This happens on multiple devices, and is not a device issue as when i restart the device it still happens, but once i restart the AP it goes back to normal operation.

i too had this a few times today, ended up being i caused a bit of a broadcast storm hopping between APs.

its strange, but turning autoconf off seemed to reduce it happening substantially.

The logic doesn't quite make sense, as it should not really matter. but it does seem to..

Interesting to see how that goes, i have an active support ticket with them although i did it very much at the start of my findings being going out and buying a few more toys to test with/against.

wasnt exactly the cheapest experiment, but end of the day it all ends up going into my "Network Gear" kit for when/If i require it to do anything else.

im purely looking at stats from a raw shown connection rate rather than real world performance at the moment.

it is strange that i get the full 633Mbit on one set of channels but only 83 on another, and is not replicatable on my 3x3 ac desktop card i picked up for testing.

Between working hospo and being busy with mothers day and my birthday on hand, I have not had the chance to seriously sit down and try alternatives. I did try with a family members 5ghz ipod, however i could not for the life of me find a way within the OS on its own to tell the speed its at at all - I should have checked the UI i know.

Atleast all my setup does work to have a connection anyway.

I have started building my configs so everything can be filtered and dug down, this obviously is one of the more basic views. If theres interest in it ill pull up all the ones i use for pfsense and the likes in another thread. I love the ELK stack.

mcraenz:

I just stood up the 3rd AP in the workshop. It was pretty sweet. Claimed/approved the device in cnMaestro™ based on the MSN#. Plugged in the POE injector inside by the switch. Went out to the workshop with my phone. Plugged in the AP, waited about 5 minutes (leds went green). Accessed cnMaestro™ my from phone over 4g, pushed a template. 30secs later the SSID is online and beaming brightly. Using the interface on a phone takes a little getting used to but it's actually pretty good.

@mcraenz I'm thinking about mounting one of my units in the workshop too. Any suggestions of what to do about the dust though? Based on previous experience, I'm kind of incapable of cleaning up as I go and so filth will eventuate. I'm now wondering if I should have bought the outdoor model for the workshop?

PS. Love the workshop construction posts on your blog. I'm going through a similar exercise at the moment.

I've just got mine sitting on a shelf at the moment but will ceiling mount it at the "clean" end of the workshop. I wouldn't worry too much about dust. There are no moving parts so shouldn't be an issue. Nice that it's POE though so I don't have to have an AC adaptor running 24x7 any more (I used to for the consumer AP I had out there).

I have a PC out there too but always turn that off at the wall for fear of the power supply failing and starting a fire. I know for for sure that thing is packed full of dust. These days I take the biggest dust-making machines outside for any significant use because it just makes too much of a mess and I don't have any dust extraction. I'm planning to turn the carport into a woodshop so I can keep the current workshop for engineering and electronics etc.

An update on my experience with these APs:

2 days ago: My partner was sick of being kicked off the network every time the cnPilot locked up, so I set up my 2nd unit (which I had intended to give away to a family member and had not unboxed) all the way down at the other end of the house in the network cupboard, with identical WLANs and roaming via 802.11r. We still both noted occasional disruptions as we got thrown off the nearby access point and forced to roam onto the far one.

Yesterday: Many friends came to visit last night including one who had a MBP and iPhone 6s which both connected successfully to 5GHz AC on the 1st unit. (My iPhone 6s would only ever connect to 2.4GHz on either unit). The 1st unit continued to be flaky as ever and by the end of the night, all 12 or so devices (mostly Android phones on 2.4GHz) had roamed their way onto the far away 2nd unit.

Today: Didn't see unit 1 lock up but have seen loads of spontaneous reboots. I restored factory settings, but then made a mistake in the config and couldn't contact it. Struggled far more than I'd ever have imagined possible to get the damn thing off the ceiling to press the reset button. (Those tabs click in and hold on far worse than the red sticker!) Did another factory restore and reconfigured.

After all this my iPhone and MBP would both connect to 5GHz AC. No idea what changed. EDIT: I did manually select 5GHz channels, previously had been auto. I then got round to installing the power injectors on my gigabit switch (previously I had been using my POE switch which is 100Mbps with a Gbit uplink) and got great speeds, over 300Mbps doing iperf on the iPhone. The old MBP (with Japanese eBay wifi module - long story) is less impressive but still over 100Mbps.

I installed a log server app and started monitoring both units an hour ago. Already I've logged one reboot on unit 1. I'll let the logs run for a day or 2 to see if both units reboot or just the one. Then I'll know whether I have a faulty unit, or if these things are just rubbish. Either way I plan to contact Cambium support later in the week and see what they can do.

its interesting that your units reboot so much.

i havent logged a single error yet in reboots.

Only showing ones i have manually done since setting up syslog catching for the APs.

@RmACK regarding the reboot issue I had my iMac lock up the AP daily. Wasn't sure what was causing it but turning off zeroconf fixed this for me. The uptime on my AP is sitting at 3 days now without any issues. I am running a bit more of a complex setup with one AP however multiple VLAN's trunked to it for different things like others are running. That is the only problem I ever had with mine and it wasn't to any surprise with me since Apple products are really bad with causing issues with WiFi (experienced this with Mikrotik and Ubiquiti products too).

I initially was going to install the e400 at my parents house (and keep using my xclaim) but after using it I decided stuff it and have instead decided to keep it for myself. Also ensure WiFi power saving is turned off on the AP as Apple devices (as I found out) really get angry with it on.
