DSL Hybrid 5G connection consistenly below 10 Mbps (previously 200+ Mbps)
2 years ago
I have a DSL connection with the Hybrid 5G extension. The DSL conneciton (50 MBps) and 5G (upto 300 Mbps). I typically get 200+ Mbps since installation, however in the recent days this has reduced to below 15 Mbps (legal minimum) conistently. I have tried moving the 5G receiver etc, no luck. Lights on the 5G receiver is green, and all connections seem active as per the Speed Port 4 router.
I have also gone through the fault reporting steps that led me through some automated steps like restaring the router, reconfiguring it etc. All of which ended in a fault being reported.
Unfortunately, the person assigned to case was not able to speak in English and gave a number to call that does not work (08003301080). Hence, I am posting it here. Hopefully, someone here can help resolve this issue.

Hey @nulltermination ,
current (latest) FW is said to have some strange behaviors, many customers (including myself) have had major problems running it. Actually, only way out seems to be downgrading to previous version. Just give it a try, if you're able to do so.
Please only do this if you have the necessary technical knowledge and you know what you are doing!
Suggested steps to downgrade:
1. get previous firmware for your SpeedPort Smart 4 model (A or B)
https://www.telekom.de/hilfe/downloads/firmware-speedport-smart-4-typ-a-old.bin
https://www.telekom.de/hilfe/downloads/firmware-speedport-smart-4-typ-b-old.bin
2. cut connections to DSL/ 5G Receiver
3. update FW (downgrade)
4. switch off easy-support (if you're allowed to ;-)), since this will re-update your router
5. establish connections to DSL/ 5G Receiver
NOTE: above steps will ERASE ALL SETTINGS. Your may try saving (before step 1)/restoring settings ...

Thanks @m.wegner you are a life saver. I can (unfortunately) confirm that the issue is, as you indicated, with the latest firmware version of the Speedport Smart 4. The firmware downgrade resolves the speed issue.
One minor suggestion regarding your instructions - if saving settings it should be done after switching off EasySupport. Otherwise, importing settings re-enables it and prior to boot the firmware gets updated automatically to the buggy version.
As for long term resolution, I wonder if anyone from @telekomhilft can provide responses for the following.

Looks like I might have spoke too soon. The downgrade worked. Then once I got the Telephony configuration in and restarted, the speeds dropped again. The firmware is still at the old version. Everything else looks okay.
EDIT: The new dropped speed is basically 100% of the DSL line now. The 5G adds nothing.

We would need some more information. Could you drop a screenshot of the 5G and Bonding connection? How do you test your download speeds?

@bambi-is-evil can you let me know which screens you want the screenshot of? Is it the status page? Or the bonding setting?
As for speed tests. Tried a few sources.
1. Google Nest device connected via LAN port is what's doing the continuous tests.
2. Tried both the Ookla and Measurement Lab (https://www.measurementlab.net/) via the Google interface. Both over LAN (speed port) and WiFi (speed port).

A screenshot of the left side of the Status page would be helpful. Also you could share a screenshot of "Internet > 5G extension > Connection".

Hi @Inga Kristina J. appreciate the response. I think you and I share the confusion, hence the post here
The speed combined is lower that each WAN source independently.
I am not sure that the cause here is that the test setting or the test is faulty, at least that cannot be concluded merely because DSL was plugged in. There are various other potential issues like for example, the Speed Port not functioning as expected.
The DSL speed is quite healthy as the building is not too far from the box. Please note that after the firmware downgrade, we have DSL on its own giving ~100 Mbps, 5G / LTE on its own giving ~80 Mbps. But when both are plugged in we get ~40 Mbps.
Also in the original screenshot, note that the tests until 16.08.2023 was almost always above 200 Mbps.
There are no mention of the change in cell ID in the logs that I can see and also note that the the speed is consistently slow, it is not just dropping once in a while.

Hi there @nulltermination, I'd like to parley over the matter we discussed tomorrow evening. I'd start at around 7 p.m., would that work for you? Kind regards - Christian H.

Looks like you have a problem with the ODU connection. The Link Status should be at 2.5Gbit/s. Please check the cables and replug them. Also unplug the ODU connector from power for a few seconds. If this does not work please do a speedtest with DSL disconnected.

That is (sadly) expected because its using a Powerline adapter. It always has been using that. Resetting them did not seem to do any good neither did disconnecting and reconnecting the ODU connector.
When DSL is disconnected the test varies between 50-80 Mbps over a few tests.

Omg...this will never ever work stable with a Powerline adapter. You need a stable and unadapted ethernet connection.

Typically it is fine, and this setup has been stable for the last 6 months. Unfortunately drawing a ethernet cable long enough to connect the two devices is not going to happen practically - maybe for testing. However, I do not think Powerline adapter is the issue here. In an ideal world, I would prefer not to use the Powerline adapter.

Testing is very easy. Just connect the Smart 4 directly without DSL and Powerline and do a speedtest. From my point of view Powerline is too unstable to work with Bonding for higher speeds. May work sometimes with luck, but it's not a stable setup.

Testing is easier said than done. Well, let me first see if I can get a cable long enough. The placement of the DSL port is not ideal.
Although, I do know that the connection just with the receiver has been stable over the Powerline . I did do some continuous monitoring and did also check the logs first few weeks. There weren't any issues as far as I could tell.
I can understand your stance on using Powerlines, but for me they do the job. The issue right now I suspect is separate to the adaptor.

So did the following tests, all provided bandwidth between 50-80 Mbps over 10 tests.
1. Removed DSL, removed power line and plugged in just the receiver.
2. Removed DSL, plugged in receiver via PL.
3. (1) but with the receiver in a different locations.

You haven't read it correct. Make a test without DSL connection. Therefore it's easy to get the Smart 4 near to the ODU and you can check the difference.
For Bonding via Powerline it's not the bandwidth that makes the problem. It's the latency. Powerline often has high fluctuation on latency. This makes it hard to sync the 2 connections via Bonding.

Woops. Yeah I missed that. Will test that out.
I get what you are saying. For whatever reason the one I'm using didn't really have high latency fluctuations when I tested it.
