Chausseefeld, Schwerzstraße 2, Fichtenweg 15

Hello,

here an update on current disruptions.

Chausseefeld

The connection to Chausseefeld got worse beginning yesterday at 11 am and broke completely ca. 3 pm.

We were on site shortly after and switched to the backup line which worked until ca. 7.30 pm – until those devices also bailed out (and could not be repaired since).

At around 8.30 pm we were on site again and could reestablish the connection over the original devices at around 10.30 pm. This held until ca. 11.30 pm.

This morning ca. 7 am all parts were exchanged (excluding power and optical fiber cabling running through the house). The connection was running very performant (max. throughput) and stable (min. latency) until it broke again ca. 7 pm.

Effective today evening Chausseefeld is offline until tomorrow morning.

Tomorrow morning we will look for a competent electrician (probably) and/or fiber optic engineer (hopefully not/as well).

Schwerzstraße 2 1. OG

The connection in Hohenheim/Schwerzstraße 2 1. OG is disrupted since approximately yesterday evening.

We will be on site tomorrow morning and assume to be able to solve the problem in the short term.

Fichtenweg 15 8. OG

The connection to Tübingen/Fichtenweg 15 8. OG is disrupted since handicrafts on Monday.

We will look for what exactly was done and how it could interfere with optical fiber cabling.

Hohenheim and in particular Chausseefeld

08.07.2020

11-15, the connection went bad
from about 15 o’clock on the backup hardware was activated on site, the inhabitants could get back into the network
from about 15 o’clock StuWe-IT started a load test of the radio bridge (this could be excluded as an error)
at 6:30 pm StuWe-IT aborted the on-site interference suppression
from about 19-19.30 the connection of the backup devices became bad (since then the devices are unusable)
StuWe-IT was on site again from approx. 20.30 o’clock
from about 22.30h the main connection was restored and StuWe-IT stopped the interference suppression
from about 23.30h the connection was lost again

09.07.2020

From 06.50am StuWe-IT was on site and replaced all parts
From 07.20am the connection is available again, but the status is not stable

The other disturbances in the Chausseefeld (radio bridges and defective fibre optic modules between the universities of Hohenheim and Stuttgart) are independent of the current disturbance.

Connection of the Hohenheim was disrupted

The connection of the Hohenheim site was disrupted from yesterday afternoon until about 16:00 today.
The cause has been found to be a defective fibre optic module in the line between Hohenheim and Stuttgart.

Unfortunately, the search for the cause was delayed by various factors (almost simultaneous modification work, delays caused by corona, etc.).

Chausseefeld

Hello,

here the current status of the connection to the Chausseefeld:

1. Netz-AK was back on the roofs CF/EG in the announced maintenance window on Sunday

2. the previous radio bridge has been stabilized over the new masts and seems to bring back the maximum capacity

3. the backup radio bridge could also be put into operation, has been undergoing an endurance test since yesterday and will be put into productive operation this afternoon

4. as of this afternoon, the two radio bridges will run in parallel operation and the overall connection will work better

5. a new class of equipment has been ordered and will be installed in a few weeks – this will allow the connection of redundantly connected mobile phone towers

Please continue to send fault messages to the mains AK. Thanks!

Chausseefeld masts

The Chausseefeld and Welfenstraße are connected via radio bridges. The radio bridges have sufficient bandwidth to supply the dormitories.

The antennas of the radio bridge are attached to masts that the Studierendenwerk has had erected for this purpose. These masts are too thin, move in the wind and are therefore already defective after half a year.
The access to the research network in the Chausseefeld is therefore not given.

We as the Arbeitskreis Netzwerke are happy to invest our free time in your network. We do this on a voluntary basis, because we think it is important to have very good Internet in the dormitories, simply and unbureaucratically. We are also frustrated accordingly.
We are not allowed to do any construction work on the building and that is probably a good thing.
We are also not here to argue with the Studentenwerk on your behalf.
Therefore we can’t do anything for you until the new masts are up.
We do not know when the masts will be replaced.
If you ask, then don’t let them refer you to us.

Forget threats of rent reduction towards the Studierendenwerk. Access to the research network is declared as a voluntary service in your lease.

In our dormitories you can always get a DSL or cable network connection, for example, because the rooms are wired in a service-neutral way.
But keep in mind that the contracts have a long duration and as soon as the radio link is working again you will surely have a slower network than ours (if the mast does not wobble).
Usable internet will cost you 600€ on the free market for two years. The installation will also take some time and if now many inhabitants want DSL or something similar, the infrastructure has to be created first. The real costs are calculated like this: 600€ per time that the free market is faster than the Studentenwerk.

If you have complaints, please remember that your counterpart is also a human being and be friendly.

Try to organize yourself instead. Our dormitories in Egilolfstraße, Schwerzstraße, Fruhwirthstraße have enough bandwidth for everyone.

The Netz-AK cannot change the fact that the common rooms in Hohenheim do not have any network access activated. If you complain about this, don’t let them refer you to us.

The networks working group has assumed that the replacement of the masts would be done in less than a week. Obviously we were wrong and we are very sorry for this.
Because we assumed that the problem would be solved in a timely manner, we did not forward your complaints.

As soon as the masts are up, we will be in Hohenheim within a few hours and bring you online, but until then please do not contact us any further.

Your Netz-AK

UPDATE: 02. JULY 2020 10:20 am

positive: the new masts are standing
negative: the storm has twisted the antenna on the old mast, so the Chausseefeld is currently completely offline.
negative: in this weather it is not possible to go to the roof to solve the problem.
positive: after the rain there will be an update.

UPDATE: JULY 3, 2020 10:20 am

The antennas are aligned again and there is slow internet again.
Probably the faster connection will be established on the weekend Sunday. The network will be offline for some minutes.
We recommend everyone to read this website, because of time reasons we will not give individual answers to the topic Chausseefeld.
All those who want to write us that the internet is very important for studying, especially during the pandemic, please consider to join our working group instead of writing us this banal sentence.

 

 

Fichtenweg

There’s a malfunction.

Cause probably is the power failure at 18.04.2020 around 01:55 o`clock.

The only report of the problem came on 19.04.2020.

Since 20.04.2020 we treat the problem as a major malfunction with highest priority.

Please report us when you are effected and how (not that you need internet) and use the subject network problems.

We are here for you

Despite the virus and all other problems we are still up and running. That you have access to the Internet is very important for us especially now.

Please do not mention why you need internet when you contact us. We know that!

We work on a voluntary basis and are therefore – as always – also available on weekends and outside office hours.

Only the sunday office hours are cancelled, but we are now also available most of the time by phone.

All the best and stay healthy
Your Netz AK

New arrival summer semester 2020

Welcome to the dormitory.

The Internet in the dormitory comes out of a box in the wall, but you can set up your own WiFi!
There is no cable coming out of the wall, this is, in doubt, the heating control!

For WiFi please read the instructions!

You can use the contact form to report errors or ask for help.
Please use the form, because we need some informations to help you.
We are only in the office on Sundays during consultation hours and there is the telephone, so please send all inquiries via this homepage!

If you live in the dormitory and are interested in networks, come by on Sunday. If you live outside Tübingen, write to us!

We are currently looking for reinforcements in the working group in Tübingen and people for e.g. Hohenheim, to be able to offer better local support.

Hohenheim connection improved

We were finally able to eliminate a bottleneck in the connection of the dormitories in Hohenheim.

Up- and downstream should now be closer to the theoretically possible 100 Mbit.

We hope that the increase in performance will be noticeable for those affected, especially during peak periods.

26. to 27. Feb Hohenheim offline

The following maintenance windows have been announced for the connection to Hohenheim:

27.02.20 00:00 to 06:00: Civil engineering work on the route in the Möhringen area through the city of Stuttgart (S21)

Concerns all dormitories in Hohenheim.
