Engenius ap clients lose internet but local lan still works

[Oconus]

Hi folks, we have a Engenius ENS1750 AP and what seems to be a random occurrence, clients (Windows 10 laptops and Android and Apple cell phones) will lose internet for a minute or so. Wireless connection on all the devices shows connected and you can actually ping and reach network resources on the local network. No pings work to IP addresses on the internet during the blips. For example, when it blips, I can ping a local server at 192.168.2.3 but not google dns at 8.8.8.8. After the minute or so (give or take) normal internet access resumes. The wired computers on the network do not experience this issue so it isn't the internet connection going out. Thoughts?

Can you ping your router which I assume is your gateway? I don't really have an answer but pinging your gateway is a better test than a server.

Yup I can ping our internal router and gateway, it's the strangest thing. Tried with 2 different access points, though they are the same models, same results.

No different than the EAP I had. What Channels are you using for both 2.4 and 5ghz modes, What firmware is installed on the AP?

If you can get access to one, I'd test against a different brand/model of AP. If internet is smooth on the test mule during that period, but not on the ENS1750, then you've got reasonable assurance it's an issue with the ENS1750. At that point, I'd factory default it (twice), then re-load the latest firmware, re-configure from scratch, put it back on the network and re-trial it in production. If it still fails intermittently on the wired side again, you may have a dying wired NIC on the AP. Could replace it through EnGenius, or through your retailer if it's within the return window. Or, if you don't have the patience, simply get another brand/model of AP in there that works and be done with it. Too many solid options available to be dealing with something like this for more than a couple hours worth of troubleshooting, especially if it's a business.

 

[Greg72]

Possible that the POE unit or even Ethernet cable is failing. Working backwards, even a switch or port on your router can be the fault. Can you move the AP near the Router and try there without the POE module? You will need the power adapter to power it.

Thanks for the suggestions folks, we have tested with different cables, network source ports even different source switches. I tried the POE adapter and tried direct from a POE switch, same results. I have a ticket open with Engenius to ask. We originally had an Asus router that worked fine and did not have this issue but it eventually died and we had to replace it so we thought going with something more 'business grade' would work better but so far we think the older Asus AP worked better.

EnGenius (Senao) is decent, especially hardware-wise, but like many small-biz / faux-enterprise makers, they're probably half-baking their code more often than they should be. Granted, nobody is perfect, and all brands do it. I hope you get some quick resolution from them. If not, and/or if you need a fix ASAP, yes, perhaps re-purposing a consumer all-in-one would work for a SOHO or micro business, but for anything more than that, I'd look to Aruba or Ruckus. A bit spendier, yes, but not by much, especially considering it's true enterprise-grade kit, whose core features just work, period. Just something to mull over as you wait for EnGenius to get back to you.
