Update again 7 months later - flawless operation with the same firmware I downgraded to. Works perfectly not a single hitch. Totally a firmware thing. 16.16.9 ... View more

Update - This continues to be rock solid stable. Meraki was out of their minds telling me the later firmware was ok and it was my fault for overloading the device. The rolled back firmware is chefs kiss perfect. ... View more

The two APs on the POE+ ports winked out again. Everything else seems normal. I decided to say screw it and put those APs on ports 5 and 6 on the MX68 with injectors. Just bypass the built in POE+ ports altogether. I had seen this before on the other hardware I had and I figure it must be something related to the firmware if it's happening on both units. Hopefully this will be the end of it. ... View more

So far the downgrade to 16.16.9 has been a dream. I had a bunch of people here on property and the MX didn't even sneeze which is whats supposed to happen. I got up to 245 clients. ... View more

Got a downgrade last week to 16.16.9 after the replacement unit suddenly decided to stop feeding data to the two POE+ ports. The rep said this was the last firmware he considered stable. Wow. So far so good. ... View more

Stopped working again today. Lights are flashing on ethernet ports but no WAN traffic. I can pull up the page of the MX in a browser and it just thinks it isnt connected to the internet. It says "there is a problem". I hard reset it, and it's fine again. Had 10 or so people on a zoom call when it went down. I have currently 156 clients total. Many do nothing but sit there and blink here and there, very little data passing. Maybe average of 20-30mbit on a 250/250 AT&T biz fiber line. Firmware updated to MX 18.107.5, which has the AMP fix and AMP is off. Utilization during this time was under 30%. Support tells me on the phone Im likely pushing it too far with the client count. I cannot believe this. I know theres a sizing guide but Ive been doing this for years with no problem. I dont use any advanced features. I have 1 VLAN for switches (which is about 15 of the clients), 1 for clients, and I speed limit everything to like 80mbit burst at this point. The only thing thats changed is the firmware and the age of the device. I dont use VPN or really any advanced features. Any other thoughts? Support is going to RMA it. ... View more

Im on firmware v 18.107.2 which is stable and I see the 18.107.4 that has this fix. Lets find out.  @PhilipDAth  ... View more

I can definitely correlate the high utilization to these file transfers. It's possible thats what it's been all along but Im not sure this account for all of it. Maybe. Definitely I was able to affect the utilization score this time around. I wish there was an alarm I could trigger at certain utilization thresholds so I could investigate. ... View more

Ok so my bandwidth is 250x250 AT&T Fiber and the max advanced security throughput for the MX68 is 300mbit. I noticed that one of my servers was doing some heavy duty video syncing to another site of mine (normal) but that it perfectly correlated to the spikes I was seeing this week. As an experiment, I used the bandwidth limiter on the server to throttle it down to 20,000kps. The results speak for themselves. 20MB/sec versus 30MB/sec but the utilization is WAY lower. It seems the increase in utilization is logarithmic as you get closer to capacity which I suppose may make sense.  ... View more

I had not. Very interesting. Meraki says not available for MX68 at least not yet ... View more

A spike! No idea why. ... View more

Here we are having turned off AMP on the 2nd. I think that was likely the culprit... ... View more

I spoke to support about this and whether I was affected and they said looking at my logs I was not affected, but was running the affected firmware. So.. we'll see. ... View more

Excellent thank you very much. I have the same settings.  ... View more

Yeah it's been well below. I'll keep you all informed.  ... View more

Indeed. I will have as large a group as I'll ever have coming in the next few weeks. I'll see how we fare. Thanks to everybody for your help here. ... View more

My graph with AMP turned off on Aug 2, and wifi speed turned down from 120mbit limit to 80mbit limit since yesterday.   ... View more

Wow. What a Gonzo problem! This actually makes a lot of sense. My device would NEVER hit high levels of utilization in the past even with 200 clients. Literally never had this issue so it's been very strange to try and troubleshoot it. This feels like it might be it. So far so good with AMP off, and my utilization is back at a very low hum. I'll keep an eye on it but this is so so good to know. @PhilipDAth does this resonate? ... View more

I do think disabling AMP is absolutely valid. My users are 99% Apple and they are savvy enough to know not to install something strange from the internet. Im not worried about them and if PC users are on my network without virus protection thats a serious issue that I am not here to counterbalance. So yeah, I dont care at all about AMP. It is literally malware scanning, right? I still have the advanced intrusion protection on. High processing is fine, but the thing has been running for 2 years without failure.  Good to know about the firmware. Maybe Ill see about rolling ti back. ... View more

I said I was thinking about it, but as you can see, there are plenty of valid suggestions for how to bring down utilization that are absolutely applicable to my use case as described. It works great most of the time, so I would not say it's close to clear that it doesn't work. In fact the most knowledgable member of the forum is on here saying the issues Im facing dont make sense to him. Don't worry about it. Thanks for coming back.  ... View more

Hey man thanks for writing as usual. You've a mensch. Yes, that was what I was thinking as well. Generally, when the issue is "happening", It lasts for about 2-3 weeks then crashes, then is fine for another period. Running stable only.  ... View more

And as far as the isolation idea - yes I have them on a Meraki DHCP guest WLAN. Works great. I have about 25 people who are there year round who need to be on a standard LAN so those are the ones who are mild users with the relatively high speed limit. I will take them all down 1/3 and see what happens. ... View more

It's easy to pop on a chat board with somebody trying to work out how to fit into their hardware and tell them to put up or shut up. I think the thing you aren't acknowledging is that I'm already quite invested in Meraki, I have an excellent ranking on this forum, so clearly I love the gear. It's not like Im just here to complain. If you are such a big deal yourself you know that there is a lot that goes into how much work the MX does moment to moment, client to client. So instead of snarky flexing, maybe consider using all your knowledge to actually assist and offer helpful information about how to squeeze as much capacity as I can out of what I have, as others on this thread are doing. Just depends on who you want to be. ... View more

great to know. I will review that and ramp down guest network allowances. ... View more

Yes, I do. 250/250 fiber line with 120 limit to all devices. ... View more
