Frtizbox has a notification option for each event when it receives an IP address.

I tried and failed to get this set-up. Must try harder.

@countryman69 thank you for the info about AVM working on a fix - that's very good to know. I will ask the helpdesk if it is possible to be updated when the fix is ready

Hi all,

I'm new to this forum and I'm grateful for the info you've all supplied.

After having a reply from AVM saying there was no path to revert to version 7.59, I've had another giving a link to do just that.

We are currently still investigating the reboot issue with the FRITZ!Box 7530 running FRITZ!OS 8.00 on Zen Internet lines.

Until we can offer a solution with a future FRITZ!OS update, you can install FRITZ!OS 7.59 that you can download from our server:

You can install the Windows based recovery tool as described in this guide:

For some reason I cannot paste the link, so here is it as text:
https://en.avm.de/service/knowledge-base/dok/FRITZ-B...
Please note, the recovery tool will factory reset the FRITZ!Box.
If you still have an EXPORT file compiled with FRITZ!OS 7.59 or older (that are usually saved and sent by push email when updating the FRITZ!OS - if set in the user interface), you can restore the settings.

Mr B

My 7530 is at least 5 years old.

Returning it to Zen today.

I'm confused now as I've had two emails from AVM.

Email 1 says "...that all 7530 routers are affected regardless of ISP"

Email 2 says "...the FRITZ!Box 7530 only has this reboot issue with Zen Internet's line and works fine with all other providers in Europe and other parts of the world"

Just gone back to the start of this thread and see NewMoon has a 7530 on PlusNet and started having problems after moving to v8. Guess that answers my question.

But then again, that is possibly the only comment anywhere linking the problem with an ISP other than Zen

Here's the latest response that I've had from Zen:

===
Here at Zen, we have been made aware that this issue is not related to the firmware update and is in fact that the chip that is used to update the Fritz!Box which may have been damaged.

As you mentioned, it does seem to be more DSL connections that seem to have been affected rather than the full fibre connections.

The issue is said to have been resolved, so if you wish to carry out the firmware update, please feel free to do so but please monitor the connection for 24 hours following this, and should there be any issues, please be sure to let me know.
===

Does this make sense to you? It's all a bit vague. What chip could be meant? One in a Zen server? And I don't like that "is said to have been"

Has anyone else been told anything similar?

I'm sticking with v7.59 until I've been told something firmer.

I too have no reason to update yet and while it is (apparently) an irreversible update.

And this is with me being all in favour of automatic patching updates for computers as long as they don't randomly restart at time frames outside my choosing.

I want to see a consistent statement.

The ISPs management system having an entry for v8 firmware that did not exactly match the version string what the routers were downloading, and so commanding them to keep downloading a "new" update was the most plausible explanation given so far, since both human data entry errors, off-by-one errors and effects of "<" vs "≤" comparison logic are recognisably common things in programming.

Either we we see a point release of the firmware with a fix or confirmation from other customers that Zen have changed something in their management system to stop sending commands for the recurring restarts.

At the very least they could be reducing that retry to one attempt per day e.g. at 5am and then the impact would be vastly less. There was never a good reason for a 20 min retry.

All the professional switches and some of the routers I use at work have a dual image system such that if you don't like what a new firmware does you reboot right back into the last known working one.

I just wanted to mention thanks to everyone's comments on this website, I had been really struggling with the constant reboots every few hours.
I also have a 7530 (non AX) which was working perfectly fine for the last three years until this v8.00 update.
After reading through the comments, I decided not to stress myself out calling Zen and resolved the issue as follows:

1. Use Internet Archive to download previous version of https://download.avm.de/fritzbox/fritzbox-7530/other... . This yielded FRITZ.Box_7530-07.56.exe
2. Follow the instructions in the wizard to set up your PC and Fritz Box to do the download
3. Read the error
"Note: The device contains basic settings adapted for your Internet Service Provider (2018-02-01_zen). Recovery could make the device inoperable on the 2018-02-01_zen network.
Please contact your Internet Service Provider instead.
Aborting the recovery."
4. Use the instructions at https://openwrt.org/docs/guide-user/installation/rec... to circumvent the error above. I only had to do "quote UNSETENV provider" and then the flash worked.
5. Now you have a stock (non Zen) Fritz Box running v7.56. Crucially, the function to "Receive updates from internet provider" which was force ticked on in the Zen firmware no longer appears.
6. Disable all automatic updates!
7. As this is now stock firmware, the auto provisioning no longer works. Configure the VDSL settings manually using https://www.zen.co.uk/help-support/general-settings-... - in particular the VLAN ID is required.
8. Everything works as it should, no more rebooting!
