if your network has DHCP it will automatically pickup an address from that so you need to find out what address its been given (normally look into your router) and browse to that address in a web browser.

 

as for the slow speed, try turning 5ghz off and see what speeds you get on 2.4ghz only, also try putting it onto 40MHz and 20MHz and see if you get better speed.

 

are you sure its not a device issue? or are you confident its an access point issue?

One AP is getting a DHCP address, one is not. I'm about ready to put a port monitor on the switch port I have the AP connected to, to see if there is any traffic coming through.

 

 

 

It's not a device issue as it works fine with all the other APs, and it's a number of devices that are having issues.

 

 

 

I'll give 2.4ghz only a crack

I tidied up my friends network yesterday. Went from a messy network run via a Fritz!Box, slow WiFi and also slow VDSL (16Mbit down, 2.2Mbit up) to a network with excellent WiFi (powered by an e400) + an Edgerouter Lite etc. Since I replaced some of the cabling he is now getting a VDSL sync of 58/12Mbit too which is a huge improvement.

Has anyone had problems with their unit crashing?

 

5 times now, I've had my unit in a state where the radios are on but nobody can connect to them. The web interface shows no radio, no clients and very high CPU load:

Over ssh I was able to determine that gzip is using all the CPU.

But why? I'm going to contact Cambium for help. When I get a chance, I'll unbox (and unsticker!!) the other unit and see if it has the same issue. 

 

EDIT: I found a thread where someone had had a very similar issue on the ePMP1000 last year. I too am trunking several VLANs to the unit.

It seems like the kind of process that would be involved with a firmware update. I'm not currently trunking but will be soon.

 

 

 

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.

I've got one that just stays with an orange power light. never seems to actually connect to the network :(

 

Can't connect to 192.168.0.1 or the 169.254 address. 

 

The second connects, but half our devices don't work and even 5ghz/ac I get 20mbit.

 

 

 

Time to attempt to raise a support case I guess...

 

 

 

 

I too have been having odd issues with the AC wifi, i have an active support ticket open however with my working role, this was put on hold over the weekend.

 

 

 

i actually made a point of going and picking up a decent AC card for my machine to test as at first i thought there was a massive 20mhz fault on the higher channels. This does not seem to be the case but possibly some sort of client limitation.

 

It is my understanding that the chipset in apple devices arent too friendly to certain 5ghz channels however i have ignored them for the time being.

 

 

 

Once i actually wake up fully ill be running a bunch more tests, have a few 5ghz aps sitting next to me setup with test channels to try to narrow things down. Ill be going as far as to flash my phones rom as thats the main device thats on hand where i see oddities with 5ghz.

 

The hardest thing of the tests is because of the DFS compliance that other devices kindly *forget* to worry about any DFS channel can take a few more minutes to come alive than normal.

 

 

 

what subnet do you run your network on normally? is there a chance its also in the 192.168.0.0/24 range and things are getting all confused when trying to connect to  the cloud?

That must have been one sad line at first! very tidy, well done.

EDIT: I found a thread where someone had had a very similar issue on the ePMP1000 last year. I too am trunking several VLANs to the unit.

 

 

Mine arent trunked yet, but i plan to drop them onto managed switches and trunk guest points by the end of this week for ease of use and segregation at the router level.

 

Ild hate to get caught on a snag of vlans causing issues.

 

 

 

Anyone else running Vlans on theirs fine?

 

 

 

I have found quite a difference in using these APs, in how tolerant they are... There is a TV on the network which loves to shove itself in and block every hole it can when it gets board. Essentially just goes full mirror mode and replicates all broadcast traffic until everything is 100% congested. No devices on the network on unmanaged switches survive that attack, However im ammazed to find out, the E400s survive it, they flow traffic quite happily! i'm seriously impressed and confused at how they quite pull it off.

 

 

 

 

 

On the note of roaming, having had a few E400s up for awhile now, roaming seems Almost seemless, the one time it is not seemless is with the 5ghz issues im noting, where a seemless transfer tries to happen, device isnt keen on 5ghz, AP is doing as expected and trying to do its job of band steering. I suspect this issue will vanish once i work out quite whats up with the 5ghz network.

What setting did you use for DFS? I don't know if I fully understand your description of the issue it caused you. I had to JFGI when setting up my cnPilots as I'd never even heard of DFS and still have only a very sketchy understanding of how the cnPilot settings for it work. 

 

As for the 5GHz, most of my devices have been reluctant to use it. I'll check with others in the house to see if any non-apple devices have managed to get 80MHz. My Apple laptop initially would only connect to 2.4GHz but after some use nearer one AP, it now is consistently on 5GHz and reporting 40MHz bandwidth.

 

I haven't noticed any crashes since I deployed the 2nd cnPilot yesterday - but with roaming I now effectively have a double redundant system, which is total overkill for my house.

When talking about DFS i mean DFS marked wireless channels

Handy references.

 

 

 

i find 5ghz is a little less "aggressive" in being picked up, i suspect tuning the 2.4ghz becons would encurage more 5ghz off the bat. Obviously the best solution to that is band-steering however, thats what it was designed for essentially afterall..

 

 

 

visibility of 5ghz networks is interesting between devices, ill edit in a coupple of screenshots once all my tests nodes are online. I also noticed with my desktop ac card, it wanted no part of a dodgy regional code being used.. not sure what to make of it really.

Okay so here is with all my 5ghz radios going, Both instances we obviously have a issue at play with a bunch of 5ghz channels not showing on my M8x.

 

Minor Caveat in the test is, computer was taken from my room with a high-gain antenna, Phone was taken about 4M away on the stairs, where there is a central point between every active AP - about the medium point where they are equal in signal levels. I have also hand picked channels to show the worst case situation.

All 2.4ghz radios were removed from the survay listing for posting purposes.

 

 

 

My normal network operates on having a fixed 5ghz/2.4ghz and a universally band-steering one. I have since learned the term "2.4Ghz" apparently means, front of the house access point... so i cant actually look at my graphs at all to get a serious idea of compatabilty.

 

This does bring an interesting fact though, the cloud management graphs are seriously aggregated data outputs.  https://imgur.com/a/jQ2SA that would imply there has been no 5ghz activity which i know is not the case.

Awaiting the return of more 5ghz devices to finalize tests however i have had a spot of time to heavily test things.

 

First problem, CM13 still has the issue with wireless regional picking that existed in CM11 it seems, This was causing some issues.

 

Second problem, im still having the 20mhz limitation on some devices outside of 36~48. This is unresolved and I am going to play with it some more this evening when I have more devices to test with.

 

 

 

My Desktop card is hard-locked to EU region, limiting the upper levels of testing I can do.

 

 

 

So I am now toying with tweaking the settings of the AP itself, getting things all working as best as possible.

 

 

 

Performance tests, synced at 876mbit i am consistently hitting just shy of 400MBit solid throughput on channel 140 at a power level of 15.

 

 

 

 

 

Because of the regulations, you should be careful of your power level if you have one on 36~48. seem to be able to double the power level there and with high gain it actually saturates the WAY closer ap be it at -80dB signal!

 

 

 

 

Overall i would say performance is pretty solid.

I'm doing some VLAN trunking (for an open WiFi network since I live over the road from the train station and am a nice person). 

 

 

I had some issues with my iMac causing devices to drop off when it was connected - this was resolved by turning off UAPSD. I get a pretty solid 400-500Mbit throughput on Wireless AC devices (below image doesn't reflect that like yours just note!)

 

 

Performance is better than my Xclaim XI-3 so that is boxed up, pre configured for my parents :)

@hio77 whats the story with the DFS Channels on 5GHz? is that just channels that don't overlap like 11, 6 and 1 in the 2.4GHz spectrum? like I mentioned earlier im using channel 44 and 108 and both are sitting at 80MHz.

 

Most of my devices are using 5GHz, have an old iPad, and android tablet that is 2.4 only.

i took a lowspeced laptop out for a bit of a walk around and test, used my new AC adaptor for it.

 

 

 

interesting enough, i peaked even higher on tests there!

 

 

 

 

obviously my testing platform was somewhat pushing too high of a snr. - also interesting, the card synced up as australia on the laptop... quite odd there.

 

 

 

@Jase2985 all DFS channels really are are ones that the airspace is shared with other things. so they are expected to 'respect' its neighbours.

 

I have concluded my issue is a two part one.

 

Firstly, 5Ghz has so many more channels that are blocked out depending on region. its like playing minesweeper finding the best device compatibility.

 

Secondly, the only channels offered in the UI that DO support 80mhz off the bad as per the spec listing, is in that low range. After there they arent shown, nor are they supported through config files. In most applications this isnt an issue, but i have noticed certain mobile devices struggle with it and default back to 20mhz (86mbit max)

 

 

 

Heres where channels should sit in NZ

 

 

 

But most of these channels are not directly selectable. i can only conclude that somewhere between NZ spec, and the many other regional specs + official spec for ac have slightly conflicting assumptions and rather than listen to what the AP is telling them its doing, they are making up their own mind and defaulting..

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.
