PM7300 and Fritzbox 4690 instructions

@cybi @user109 Here are my instructions, which work with the products mentioned in the Swisscom network:

connect the Zyxel Bridge to the fibre optic socket and connect it to a PC with a network cable
open Zyxel Web GUI with 192.168.0.1 and configure as a bridge (without VLAN!!) (changing the IP address is not so important on a bridge, I think)
connect Zyxel with fritzbox 4690 at the WAN port and a PC at a LAN port
open WEB-GUI of the Fritzbox, set country Switzerland, fibre optic modem, other Internet service provider, Swisscom, set VLAN 10
to enter option 60 on the Fritzbox, you must export a backup as a file under System backup, open it with a text editor and add the line

class_identifier = “100008,0001, ,AVM dhcpdiscover 1.0 dslforum.org”;

and save it. (use straight quotation marks!)
so that the new file can be restored to the Fritzbox, it must be loaded with the FB Editor (runs with java - it is best to use an x64 Windows PC) with file-open and simply saved again (do not enter a user name or password!). This is necessary because the FB Editor creates a checksum, which is important.
then import the file on the Fritzbox under System Restore.
after a restart, the correct splash page should work at www.swisscom.ch/access!
finally you can install the firmware updates of the Fritzbox and the Zyxel Bridge (update available on the studerus.ch page: PM7300 Firmware March 25)
link FB Editor: FB Editor (exe and jar file)

Good luck with the setup!

Albatros2

many thanks for the info

I tried it briefly but the Fritzbox does not accept the file when importing, invalid file. under which dns1 dns 2 did you enter it? there are several such entries.

Thanks and greetings

Albatros2 · 2025-03-27T16:36:00+00:00

cybi it is the first dns1 dns2 entry from above. and did you open the file in FB Editor and save it again?

cybi · 2025-03-27T16:49:42+00:00

Albatros2 Have you opened the file in the FB Editor and saved it again?

Sure 😉

Then I’ve entered it in the right place.

Funny……

Albatros2 · 2025-03-27T16:51:43+00:00

cybi can you post a screenshot of the section before dns1 and after dns2?

cybi actually looks good. did you keep the .export file type? You can try another text editor or insert the line in the FB Editor first.

Albatros2

I have already tried everything, with the same result, no valid import file.
If I don’t change anything, the import works but is rejected after changes.
Very strange.

Albatros2 · 2025-03-27T17:45:22+00:00

cybi I think you also chose a password when exporting the backup file on the Fritz GUI?

cybi · 2025-03-27T18:07:57+00:00

Albatros2
Yup, you can’t do without it

Well, I asked the AI and the problem was quickly found.

Answer

You’re very close, but there’s a tiny little typo that the FRITZ!Box Config Parser doesn’t like at all 😄

Problem:

The goose quotes “…” are typographical (i.e. smart quotes) instead of straight ASCII characters ".

I simply copied the line from the forum and didn’t notice the error.

So always pay attention to the little things 😆

Albatros2 · 2025-03-27T19:24:37+00:00

cybi yes, they were still straight in the community editor. After publishing it converts them. nice and stupid. I added a comment.

cybi · 2025-03-27T20:21:00+00:00

So I did my first speed test.

Down as usual 8Gig
Up 4-5 Gig

I’ll probably have to take another look at the Zyxel bridge and update it
It’s not the FB…..

Albatros2 · 2025-03-28T11:41:14+00:00

cybi I have exactly the same speed values.

cybi · 2025-03-28T12:36:04+00:00

Albatros2 ok then I’ll check with Studerus because with the IB in front of the FB there is 8Gig in both directions

user109 · 2025-03-28T13:17:28+00:00

cybi it’s always the case that 3Party solutions are not as optimised (speed-technically) as the devices from SC.
See also back then with vectoring and G.Fast with AVM.

user109 user109

that may have been the case in the past, but with the standardised XGS-PON, other manufacturers also achieve full speed.

Let’s see what the manufacturer has to say.

cybi · 2025-03-28T13:59:37+00:00

user109 See also back then with vectoring and G.Fast with AVM.

At that time I had about 5-8% less speed on DSL with the FB compared to the IB

Here we are talking about a 50% drop in upload speed with fibre, which in my opinion should not be the case.

cybi · 2025-03-29T12:07:29+00:00

In the meantime I have noticed something else.

VoIP no longer works. Neither via Fritz nor directly on the Grandstream. Setting it up again didn’t help either.

I’ll probably have to try the Zyxel again 🤨 although there’s not much to set as a pure bridge.

@Albatros2

Answer from Studerus who have clarified it with Zyxel:

Basically there are no restrictions with the PM7300.
The device takes over the provisioning settings from the OLT side.
