Re: MR 26.7 Firmware

We haven't used r for a while as we use WPA personal and there is a security risk if combined

Re: MR 26.7 Firmware

Hi guys,

 

We also had the bad addresses issue. We solved it by disabling the mesh feature on the wireless. This was also confirmed by meraki that this is an issue on the new mr45/55  models. Hope this helps!

Re: MR 26.7 Firmware

Thanks for the response @Brambo

I had a feeling this was directly related to the new first gen 802.11ax MR45/MR55 models.

Re: MR 26.7 Firmware

Ah, that is why we didn't get the actual problem, just some alerts, we had disabled meshing!

Re: MR 26.7 Firmware

Mesh was disabled on our site and we continued to see BAD_ADDRESS.

Re: MR 26.7 Firmware

Meraki support recently came back to us with the following.  We will pass on this for now and wait for it to be fully tested but FYI out there to others who may not be able to afford to wait around. 

 

 

Greetings, The product team reached out and mentioned they have recently received reports of issues of this nature occurring on 26.7.

They have provided a test firmware that needs to be applied on the affected networks.

As this test firmware cannot be scheduled, you would need to call in during a maintenance window (as your APs will reboot on the firmware upgrade) so that we can apply it for you while on the call.

Re: MR 26.7 Firmware

So I think the meshing was a red herring, and the real issue is the MR45/MR55 =/

Re: MR 26.7 Firmware

We also disabled 802.1r but that was not related as to my understanding and what the engineer told us.

Re: MR 26.7 Firmware

Hi guys,

 

Bad news this morning we had again bad addresses in our dhcp scope so yes red herring :-).

Good news meraki installed a patch and we havent had the issue anymore!

So spam meraki support for the patch if you really need it! 😉

What are your specific conditions that are having you run into this issue?

 

MR45/MR55 model?

L3 Roaming on the SSID?

 

Just want to validate what it is causing it since I'm not having the issue.


Did support tell you what version they pushed you to? 26.8? Did they mention what the specific bug was?

Re: MR 26.7 Firmware

MR45 and we are using bridging not l3 roaming .We run our layer 3 on a MS355 switch and dhcp relay to a microsoft dhcp. We had the same issue with the DHCP running on the switch(pool was running full) at first thats why we migrated to a microsoft dhcp server.

Re: MR 26.7 Firmware

Thanks for the feedback @Brambo

I think this just confirms the MR45 and MR55 are still having a continuation of issues since their conception.
