It should be a cable problem. I have encountered a similar problem. One of the APs was in repeater mode. Either the cable b/n the AP and the Switch is long or the cable has a problem.  When I checked it was connected to another AP wirelessly and the cable was not working. Once the cable problem was resolved it changed to Gateway mode.  ... View more

Hello.   I have a problem with the same error but when I connect a Cisco 7940 Series phone to my Meraki MS355-24 switch, when I connect the phone to the port, the port immediately blocks and I get the Very high proportion CRC error. I have already used several different cables, but I don't know what is causing the error.   Thank you ... View more

Hi Philip,   The fact that the switch IP needs to be on the uplink VLAN is a great point.  Do you have a documentation link for that?  I tried to find one and couldn't.   Thanks!   Tom ... View more

When you're splitting and combining, just a heads up: You may need to scroll way down to reach the end of the splitting box @BrechtSchamp shows, on a secondary scroll bar.   If your MR/MS network is "combined", split it. Combine the has-device MX network in with the resulting switch and wireless networks. Delete the empty appliance-type network once you're done, for tidiness. ... View more

I would make a batch file with the following commands to run, then run as administrator-     netsh wlan delete profile name="xxx" interface="Wi-Fi" (where xxx = duplicated wifi name, copy/paste for all duplicate instances) netsh int ip reset netsh winsock reset shutdown -f -r -t 5     It's definitely a Windows issue. On the machines that you're seeing this on, is there OEM wireless software installed? On Dell laptops there's a ridiculous OEM program called "Dell Unified Wireless Suite" that has wreaked havoc for me on occasion. I always remove any OEM wireless software and just force drivers only install. ... View more

One thing to remember, especially with Dell laptops, is that the OEM uses some proprietary software/drivers that don't always get along with WAPs. If a Dell has the "Unified Wireless Driver" software (or whatever it's called), you should definitely uninstall that POS software, uninstall the driver, reboot and let Windows reinstall the drivers. Unfortunately, most of the time you won't be able to update the driver and are stuck with whatever 3 year old driver Dell has released. I refuse to use HP products, so not sure if they're still as bad as Dell for that. ... View more

@Asavoy wrote: @BrechtSchamp - A Catalyst 9200L is way more switch than needed for an offline scenario, not to mention cost prohibitive and 24port is the smallest (I believe).   @Tomek I would recommend a SG300-10MP or SG350-10MP switch if you need a managed swtich with some POE ports. Newer and much better than a 2960! Good point, I had disregarded the 8-port part. I was thinking of the regular 2960X. ... View more

On Cisco "classic" you have to put ip-helper addresses to the VLAN´s to allow DHCP requests over different VLANs:   interface Vlan1 description Management VLAN ip address 10.1.0.1 255.255.254.0 ip helper-address 10.1.2.10 ip helper-address 10.1.2.11 ip helper-address 10.1.2.12 no ip redirects ip directed-broadcast 101 no ip proxy-arp arp timeout 60   maybe you can do this on a MX ? ...

My issue is on ~13 MR18's, all on 25.13.  No other WAPs on the network (although plenty of others in the building polluting the air).  Hopeful that maybe a firmware update is out there - is there a way to force the beta on, or is that not a great idea with outstanding bugs?   Has been quiet due to Easter, so not sure how the issues are right now - I changed a few settings last week out of desperation.  ...

It's kind of a dual stub- 3 sites on one stub and 2 on another, but all still routing around each other.  The ME3400 is just a collector, that I know of.... it's AT&T's device and I don't have admin access to it.  The 3 sites in question go like this- MS320 to ME3400 onsite, then to the ME3400 at the country.  That goes to a Cisco 3560 which is where the VLANs are defined for each site.  Then that traffic is passed to a MX400 in passthrough mode (just so we can see all traffic at one point) and that's the "end" of my network.   I've seen the network do this before up until the providers were split.  Rebooting the ME3400 at the COE ended up solving the issue for awhile (with a lot of other background work first), so I'm very much inclined to think it's the issue.  There was a high rate of internet collisions on the uplink ports of each of the 3 MS320s, which was solved by forcing 100MB Full Duplex on the port, but that had really only started a week or so before Thanksgiving.  The MS320s were also reporting that the 'Uplink is not using the same VLAN settings as it's connected switchport" which is very similar to the behavior I had seen before, which is what led me to power cycle the ME3400 in the first place, which caused the failure of the device.   Anyhow, I can probably deal with it like this until spring (new circuit being put in place) because it's not causing issues with normal DHCP devices.  The biggest issue is that I would have to go around to every device that has a reservation in the DHCP table and set a static IP, otherwise they'd just have intermittent connections.  Just saw it this morning with my CTO's PC that was set as a reservation, and that had been working fine last week!  I don't see any way to get the MS320s to stop ACK flooding in the current setup. ...

You'll may have to contact support as I am not sure it's in the Beta channel yet. I can tell you that this seems to be the only issue I've seen with performance, so far. This is at a site that ONLY has MR34 devices. (FWIW- I tested MR42 and MR52 throughput at same site and the MR42 was the fastest on 2.4Ghz band. Go figure) ... View more

I have a few hundred MR34's in production (generally in networks with MR32's) and do not see this issue on earlier 25.X firmware. Perhaps the 34's never made it down to NZ @PhilipDAth? We're running 25.3 today as 25.9 (and later) has a blocking bug for us with Windows clients randomly being disconnected from the network.    The only thing I will note is that we generally use a significantly higher minimum bitrate (because we go for high density with an AP in every room) and auto channel width for 5GHz. You should easily be able to hit 300Mb+ on an unloaded MR34 with a client that can handle that type of throughput (2016/2017 MacBook Pro's are great for testing VHT WiFi).  ... View more
