I haven't yet received a response to my AVM ticket. I called Zen again last night. It was my third call, on the first call (Saturday morning) the agent semed clued up, she tested the line (which was fine) and fixed my 5GhZ wifi to channel 36, telling me to call back for a new router if it didn't work. It didn't work so I called back on Monday morning, when the agent told me that it is now a known issue and she did a factory reset which she said should fix it. The factory reset didn't fix it so I called again on Monday evening, on that occasion the agent seemed to have no knowledge of the OS8.0 issue and insisted that I plug the router in to the test socket for 24 hours before they would do anything else. I explained that the issue had started immediately after the OS update as well as what his colleagues had said to me and I refused point blank to waste more time with ther test socket course of action. After some time - and with the intervention of a supervisor - they are now sendinjg me a 'loan router'. I'm still fuming at the service I received on the third call.

If you look at the AVM website there are numerous pages explaining how to do a factory reset. I have done it a number of times. If you want to avoid configuration problems then you need to do a complete rebuild: ie, set up phones etc from scratch and not use a saved config file.

There are also recovery files on the AVM FTP website that enable you to rollback to the previous firmware.

If Zen is doing this for you then it would seem to me that they have added something to the files that are being deployed. I have looked at an Aussie Fritz site and there are no reports of v8 problems other than some minor language errors.

I'm using a zen supplied 7530 and upgrading to v8 didn't cause any issues. Theen again it's not my main router and it's LAN connection rather than FTTC. Sounds like it's VDSL issue. I upgraded directly from Fritz box, not sure if it's customised for zen, can't see them wanting custom firmware, just a config file to retrieve the necessary settings.

I got v8 on my 7530 overnight.....3 restarts at least this morning.

Not happy.

My 7530 AX updated on 27th Sept and has been up since; no restarts, no dropped connections. 2.4GHz and 5GHz Wi-Fi enabled and permanent VPN connection up to another FB router at another location...

Maybe not what those having issues want to hear, but it's not _all_ boxes!

The 'loan router' arrived today, a newer AX model 7350 then my existing one. It may have been a bit foolhardy but I updated the OS to 8.0 and it has been running for the past four hours with no drop-outs. If it keeps this up then I will be seeking to make the 'loan' permanent.

I've looked at the AVM websites / manual specs for 7530 vs 7530 AX and am unable to tell if the AX model has additional RAM or just that Wi-Fi 6 is the only significant change.

RAM size is not shown in the UI either, only a graph showing memory usage as a proportion of 100%.

OpenWrt lists 7530 as having 256MB RAM and 128MB NAND Flash storage.

Zen have had me downgrade the DSL version to previous, which hasnt helped.

Ive also got the stability sliders well on their way to max stability, also not helping.

Have a ticket with AVM too, and have supplied them all the diagnostics, but no response yet.

Pushing for a replacement router as this is very disruptive.15 plus restarts yesterday, similar today.

I have some experience of this having been on the beta s/w for a while. For DSL issues, Zen are recommending this at the moment but, as some have noticed, it doesn't always work.

FOR xDSL only: FTTC or ADSL: Using the previous DSL version

Click "Internet" in the FRITZ!Box user interface.
Click "DSL Information" in the "Internet" menu.
Click on the "Interference Resistance" ("Line Settings") tab.
Click "Interference Resistance Settings" to display all of the settings.
Enable the option "Use previous DSL version".
Click "Apply" to save the settings.
Now the FRITZ!Box enables the previous DSL version and then restarts. The restart will take about two minutes.

Other bugs that I have found and reported are :

1) In the Events Log > Internet Connection, it sometimes does not remember the 'history' of DSL problems such as line drop. You only see the last event. A subsequent event will over-write this

2) I was very interested to see reference to the possibility that older 7530's may not play nicely with 8.0. Reason is that I have two 7530 - one is a few years older than the other. The newer one will have an option under Internet > Mobile Network. The older one does not list this option. The Mobile Network option is damn useful as I've been having a lot of DSL issues as well although a lot down to 2km of geriatric cable from the cabinet, many joins mostly covered in verdigris. I have a dongle inserted into the USB port with a SIM from Giffgaff.

3) Don't try to restore from that Saved copy. It's bust. You can't restore which is a right PITA. You get a generic error message and that's it.

Thank you for pointing out the "Use previous DSL version" option. I'll try it on my 7530 later to see if it stops the frequent reboots with 8.00.
