Chausseefeld Feb 2021

Unfortunately, the buildings in Chausseefeld are offline right now.
The buildings in Chausseefeld are connected to Egilolfstraße via a radio bridge.
Here the connection seems to be interrupted. Could be a storm, snow, lightning or a defective cable.
We as the Netz-AK would like to help you, but we have no access to the radio bridge.
The IT of the Studierendenwerk seems to be active, but needs a janitor.
Janitors are not available until Monday…
Since we don’t know what exactly caused the outage, we as Netz-AK won’t claim you would be online if we were responsible, but on weekends we are the only ones who read your mails.
So take a book and feel free to complain everywhere from Monday on.

Your net-AK on saturday morning before 7 a.m.

P.S.: Two pictures showing that there was some internet for a short time (hope?) and the last 30 days were without outages.

Welfenstrasse without power

Since ~ 5:17pm the connection to the Welfenstrasse is down.

Probably there is no power at our switches in the basement.

Someone will be there tomorrow and fix the problem.

Sorry, but without electricity we can do nothing for you by remote!

Update: at 5:54 pm the power was up again.

Kaiser-Wilhelm-Str. Störungen 2

Some rooms still use access points and cause Internet failures among their housemates.
We are enforcing the rules of how to make Wi-Fi in Geisslingen now.
The connections from which the malfunctions originate are now disconnected from the network at 11:45 am 05.11.2020 and should please contact us using the form.

Access to the Internet is especially important right now.

    Kaiser-Wilhelm-Str. errors

    Some rooms have access points instead of routers, which causes Internet failures for room mates.
    Also in Geislingen the instructions for Wi-Fi should be followed.

    If your connection is not working since Friday, 23.10.2020, your room has been disconnected from the network to guarantee the others access to the internet.
    Since only one person has contacted us over the entire weekend, we assume that our poster is not hanging. Please ask the StuWe to put up a poster or print it once and put it up in the entrance area of the house. Poster as PDF

    Please contact us using this form so that we can unlock you as soon as possible.

      Hohenheim and in particular Chausseefeld


      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


      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.).



      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.




      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
