Just a follow up...
I applied a buck converter to the external 5V power and the wifi is working again as nothing has happened.
So I'm pleased that I asked for help as I probably would not think of getting the power from the external 5V. It was easier than I thought to fix it.
Would it be very difficult to make a batch rename of all dozuki links in the database? I mean everytime I'm searching for something and entering a thread about it there are loads of links do dozuki which of course is broken. Most of the old comments in the Duet3D Forum refer to dozuki which is quite annoying.

@stout are you sure you have 3.3.0 installed? can you show a screenshot of the general settings page?
I have full control of what I've got .-) I use two different systems, both with latest official releases.Both gives the same result as shown previous.
First I used both systems with black background but it happened more than once that I shut off the wrong system during print, therefore one white and one black. But I don't really like the white backround and would like to change to blue or whatever. Don't find any CCS in /www for it. Is it a .js-file?

I am using version 3.4.5 both firmware and DWC.
I finally got it to work. It was the access point and a network cable plugged in but not to 100%. The little RPJ45 tap was lost. (embarrassed)

Thanks for all your constructive positive inputs.
Believe it or not. Battery life is just fine. I can (if I want) watch Netflix 1 hour/day for a month and then I get a warning that it´s 10% battery left. That's good enough for me, age doesn't matter, it's working!
But who needs a battery when It can easily been connected to USB. I can even use it as an extension controller to Logic Pro without any problem, so why throw it away? Beacuse it's 12 years old?
The "old handhelds" are not rare. People put them on the shelf because the software developers eager to not make their software backward compatible, which is a shame. If someone made an app for these "old handhelds", I am 100% sure that they will start using them again as they are actually still working. If that happen they will probably be hot stuff on the used market and shoot of in price like old mobile graphics cards did when someone found out that you can swap an old iMac 2011 graphics card with a newer and get a decent computer for peanuts.
I also have an Imac 2011 27" i7 3.2Ghz with a"new" graphics card, and it's absolutely stellar in 2023 when it comes to average usage. I use it all day for all 3D-printing work/apps. It's not much (if any) difference to my newer iMac's when it comes to this.
In the day when I was a programmer (read 1983-1999) and used assembler, system code, fortran, pascal, C or whatever there were never a problem because the application was stand alone and would always work. But it was of course suited for a particular task and there were only one or two platforms which made it easy. Those were the days 
I am still frustrated not be able to use a fully functional iPad for such an easy task as running an internet browser with DWC.

I have several Duet boards and suddenly one of them a Duet 3 mini 5+ lost the static IP-adress and I have no access to DWC anymore.
I've been using this card for about 2 years now and I have no clue what has happened and how to make it to access with a static IP-adress. I've tried everything but nothing helps.
M587 S"network" P"pword" I192.168.1.100 gives me 192.168.1.27 and I have no access to it. All my connected units have static adresses that begin from 192.168.1.100-254.
Reformated the SD-card and copied a known working copy. Reset the connection, updated the firmware with M997 S1
When I did M588 S"*" The Duet couldn't find any networks It's connected to an Access Point one meter away with good signal.
Everytime I restart the Duet I get 192.168.1.27 and the connection is off in PanelDue. I must type in M552 S1 to get it going and still have no connection to DWC.
When doing a M122 I have IP 0.0.0.0
I'm at a total loss now.

@Stout Can you give me a hint what in v3.4.5 doesn't work with old Safari versions? I've got an OS X High Sierra test setup with Safari 11.1.2 and my v3.4 dev copy starts up correctly there. The code editor shows up as well.
I am not using Duet on old MacOS (well.. using Big Sur as latest version which makes it old too but have never had problems on earlier MacOS's) only on old IOS versions as they can't be updated anymore.
I am sorry, I can't give you any hint except that the webpage is loading and then immediately gives a white screen.
None of the browsers accept DWC on Ipad or iPhone pre-IOS10 which is very annoying as the hardware hasn't changed, only the browser software. All installed apps are normally working fine although sometimes slow, but they are working. Even Amazon Prime and Netflix on IOS 9.3.5. I can browse the internet on Safari, Chrome and Firefox but have no access to DWC!
EDIT: Addition. I tried to downgrade DWS to earlier versions in hope to get a view on the ipad but the same whing occur. A white screen.
The strange thing is that it used to work with earlier versions of DWS and as I am not able to update the old ipads or iphones since DWC stopped working, there must be something else going on with the software/DWC.
@chrishamm That sounds that there is hope.
By the way. Is it possible to downgrade wifi from 3.4.5 to whatever? I simply get no respond from the firmware.

WebKit API
That's the new "green" world we live in, unfortunately. Throw away functional electronic equipment and buy new because the software say so.
Well, I thought I should be able to use the ipad as a touchpad/pendant my new built CNC for which I use a Duet 2 wifi. I suppose I have to buy new functioning electronics then (not a new ipad but controller board). Pity when everything is ready for a test run.
Thanks for your reply.
No, no "new" browsers are supported. The last Chrome vesion is 63.0.3239.73
i think I've tried everything with every bundle from 3.0 and up. Copied them to the SD card, installed from the web browser. I now have this after installing Duet2and3Firmware-3.1.0.zip and DuetWebControl-SD.zip
No, IOS 9.3.5 is not supported since a long time. See my post from May last year and it's still marked as unsolved.
