After firmware update 17.10 - WLAN, iOS devices are slow and App Store runs only after reload

Hi all,

 

After the firmware update to 17.10 are:
- WLAN iOS device very slow when loading information or web pages (often only after multiple reloads).
- Same with App Store
- Sometimes the device switches from WLAN to mobile network

 

With 17.9 we did not have the problems. (After rollback, OK)

 

Does anyone have the same problems? Solution?

 

Thanks.

Kind of a big deal

I had the same issue, I rollback the firmware too.

Update: I did another test with a Windows 11 Lenovo Laptop. With v17.10, the update 22H2 hangs at download 100%. Same test with 17.9 - installation runs.

 

It is a WLAN problem and not an iOS issue.

Yes, after 17.10 very slow on all wireless devices.  Rebooted and power cycled, all without effect.  Not wanting to roll back to 17.9 because 17.10 fixed an issue with wireless clients not honoring L7 filter policy.  Arg... trade one problem for another :-(.

Is this happening on an MX with built in WiFi or on a network with MR devices?

In my case was MX with Built in WiFi

 

Yes, my MX67W with built-in wifi.

Yes, also a MX67W with built-in wifi.

I can confirm now all problems solved after the downgrade 

@Meraki I think think Meraki support need to take an action as it will force the upgrade again and fix that bug on 17.10

Has anyone tested the newest firmware - 17.10.1? WLAN problems fixed?

The issue still happens.

Same issue on 17.10.1 for MX64W. Unusable stable release candidate.

I will test It, just to confirm.

I tested It and the issue was not solved on 17.10.1.

Thanks for testing. 

I will test the new version (17.10.2)

Same issue guys.🙁

We ran into this as well, still on 17.10, but, I was able to at least work around this issue for a small branch office.

 

Create a policy group for IOS devices

 

Create a L3 Firewall rule to allow 17.0.0.0/8 (apples subnet)

Create a traffic shaping rule for subnet 17.248.190.0/24 (17.0.0.0/8 would also likely work) and set the DSCP tag to 46 (EF - Expedited forwarding)

Tell IOS users to turn off "Private wi-fi addresses for the wifi network connected to" https://support.apple.com/en-us/HT211227

Move IOS users into correct policy group

 

Again, workaround for a small office, so does not scale too well, this was done on a MX64W

Annoying they made it stable, now we cant roll out on 16.x anymore without calling meraki support.

 

imo Meraki really should always let you choose between 2 latest stable versions.(so a 16 and a 17 fw)

Anyone opened ticket with support on this issue ?

I created a ticket. No update yet.

I just opened a case as well to pile on to hopefully weight the priority a bit, as this has been going on for far too long.

Any update?

Meraki automatically scheduled upgrade to 17.10.2 despite all IOS device will not work over the wireless. Crazy!

Yes, I just got bit by that as well.  Forgot to set my firmware upgrade to "Ignore".  Had to rollback to 17.9 again to correct performance issues on wireless.

sry, no news.

Are these wireless issues happening on MR AP's or just MX's with built in wifi?

I have a MX with built-in wifi.

I can only confirm it happens on my MX64W with built-in wifi.  I do not have a separate AP.

I am going to open ticket now from my side and i think we need this upgrade as i am facing another issue with my MX67W as i have 3 SSID;s and one of the SSID's SSID1 in specific stooped working (No one can see it ) and the only solution after all the troubleshooting is to move the same config to SSID4 !!!

Not sure if you have same issue

Same issue here, Did you try to disable content filtering?

Same issue here on 17.10 and 18.102 onwards. 18.101 works fine for wireless clients on an MX68. Haven't tried disabling content filtering yet, just sitting on 16.x

What is the last-known-good 16.x firmware?  I am tired of waiting for a fix for the 17.x series and want to ask support for a 16.x.  

Support actually responded and advised that 16.16 is the last-known-good 16 branch version.  I've asked them to make that available to me and I will give that a go to see if I can get back to full L7 filtering and expected performance on my wireless clients.  I've been a Meraki MX security appliance customer for over 5 years and never had this much trouble.  Sad to see the product line degrade like this.

OK, applied 16.16 and L7 filtering & performance appear to be normal and as expected at this point.  I will hold on this version until they resolve the 17.x issues.  I am keeping my case open until they fix the 17.x branch.
