We started off with only a few APs alerting, some stated the alert started back in November which were admittedly missed by the team. While others only started late Feb. However 31.1.6 has been recently rolled out across multiple sites and APs that were never alerting previously are now coming up at 100Mbps full duplex. As an example this AP an MR44 was connected at 1Gbps since at least the 4th March as that is as far back as the scale will allow for. Then after a firmware update from 30.7.1 to 31.1.6 over the weekend we now had a drop then it came back up at 100Mbps at 15:06. It only ended at 15:46 because we forced the port back up to 1Gbps. The AP and Switch were updated on the 30th.   The ones that alerted back in November also refuse to come up at 1Gbps so those likely are genuine cabling issues. But the ones that have alerted in Late Feb March and now April we are able to set back to 1Gbps and some will run for 24 hours before reverting while others will run for 2 weeks before reverting. If there was a genuine cable issue why is it taking so long to revert and the switches don't show any errors on the port. This has mostly been MR36 and MR44 affected and not any of the newer CW APs. ... View more

@GreenMan We have two customers that are in an area where using DFS channels is near impossible without receiving the dreaded DFS event detected and all the APs start switching channels and eventually land on the already busy UNII-1 channels. Maybe useless was a bit strong but it currently feels like the MR44 is getting a bad deal here as it leaves the higher performing APs with only two channels at 40MHz or one usable channel at 80MHz without those UNII-3 channels. We have been alternating the MR44 APs with channels 42 and 155 at 80Mhz for great performance in denser office space, with the rest of the office using 40MHz channels on the MR36 APs. I agree with @Paccers that the DFS requirement was removed for the UK market for 5725-5850MHz with a maximum mean e.i.r.p of 200mW as per IR2030/8/3, which is mentioned in the links Paccers has linked to from our regulator Ofcom. The access points currently seem to be working to these rules as no DFS events are observed when using these channels and the AP will use these channels straight away rather than the usual delay when selecting a DFS channel. ...

Just had an update from Meraki support and it's rather short list of supported APs MR28-HW GR12-HW MR57-HW CW9162I MR36H-HW CW9166I CW9164I Which means all the MR44s that we have been deploying recently are now useless at one of our sites, hopefully this will be added back in soon. ... View more

Just had an email from Meraki that the UNII-3 channels are now going to be disabled for the UK region on the 25th. It doesn't explain why in detail only that it is to meet regulations. Anyone else get this email? I don't understand why they are taking the channels away when there are documents from Ofcom stating that it is permitted.     ... View more

Did you have to manually set them on the AP itself or via an RF profile? I've just seen manually setting on the AP directly seems to work but the profiles for auto channel don't seem to get used. ... View more

Has anyone actually seen an access point use these channels? Across multiple organisations I haven't seen an MR36, MR44 or MR33 actually use one of these UNII-3 channels. I've tried creating a new RF profile for an MR36 with only those channels enabled and it seems to ignore the request and uses a different channel anyway when you try and do this with an MR33 it comes back with an error message that the selected channels aren't supported. ...

It looks like its being rolled out still as some Orgs show it as available and others its greyed out. Does it make a difference if the Org / Site has MR33 vs MR36 APs? ... View more

The regulatory domain now shows as UK instead of CE. Comparing a UK site to a German one Does this mean UNII-3 may become available soon to the MR36 / Z3 and other units? I did try raising this a support ticket back in June and was asked to submit it as a feature request, which didn't get a response. Below are the Ofcom articles stating when the regulations changed.   https://www.ofcom.org.uk/__data/assets/pdf_file/0032/98159/5p8-Regs.pdf from 2017 where 5725-5850 MHz are permitted https://www.ofcom.org.uk/__data/assets/pdf_file/0036/198927/6ghz-statement.pdf from January 2020 where 5725-5850 have DFS requirements removed.
