Christmas 2024

The Christmas season – for many, a time of reflection and peace. But for us at Netz-AK, it stays busy! Even during the festive season, we’re here for you. Whether it’s sudden technical issues or those little things you’ve always wanted to configure properly – we’ve got your back!

Of course, there are limits: if solving a problem requires “paid staff,” many of them are rightly on holiday now.

Why? It’s simple: volunteers rock!

A big thank you to everyone who helps us keep going. A special shout-out to the caretakers, Carmen Braun and Mrs. Hein.

Wishing you a Merry Christmas and a great start to the new year!

Your Netz-AK Team

Netz-AK goes to Hohenheim!

On Friday, the working group, along with its new members, will visit our technology in the dorms in Hohenheim. We expect to arrive at Egilofstraße around 5 PM and from there, we will visit Welfenstraße and Schwerzstraße. Whether a short tour of the campus or a visit to our dorms at Chausseefeld is possible will be decided spontaneously.

If you would like to meet us, keep an eye out for a group of nerds – it’s safer to let us know in advance using the contact form (Join Us).

The reason for the tour is our new members from Tübingen and our first interested person from Hohenheim! Besides getting to know the locations, we hope to gain insights into the needs of the dorms, which we often view as “outlying areas.”

 

2024 new in the dorm?!

First of all, it’s great that you’re here – welcome to the dorm and our volunteer-managed network.

If you’re new to the dorm, you’ll probably want to meet people. A good reason to start a conversation could be because you have a question – whether it’s about living, where to shop, or, likely why you’ve landed on this page, about accessing the internet from the dorm.

There’s internet in the dorm; it’s fast, and you don’t have to pay anything extra for it.

You can only get online in the rooms wirelessly through WiFi if you get yourself a WiFi router, which is what most people do. If you already own a router, make sure to read our guide on Wireless internet in your room. If you don’t have a router and are looking to buy one, I’ve just finished a blog post describing what I would do if I were faced with this task.

If you ever run into a problem or need help, don’t hesitate to write to us via the contact form. Please always use this form so we have all the information we need to help you quickly and efficiently.

Unfortunately, we can only help in German and English as a group, but in all communication, we advise you to use the language you speak best and not to use automatic translators. The quality of your German or English shows us what you might mean if you’re not well-versed in technology. If you send us a technically perfect text using AI, you will get a response that matches the level of your request, and it could unnecessarily complicate things if you’re not an expert.

Have fun and a pleasant time in the dorm!

Your Netz-AK (short for Netzwerk Arbeitskreis = Network Work-group)

Maintenance Work Announcement week 3

In week 3, which is from January 15 to January 21, some maintenance work is scheduled.

Hohenheim

The maintenance work starting on Friday will be long and unpleasant for the people in Hohenheim.
The fiber optic lines in Hohenheim to get extended to be used in a different location because of the renovations.
Without the fiber optic line, there will be no internet there.

The work will be carried out by a specialist company and is scheduled to start on Friday morning, which is January 19.
The work will take a long time, so we announce a complete internet outage in all student dormitories in Hohenheim from Friday morning to Saturday noon.

If it’s done faster, please avoid sending us messages all day. It won’t speed things up.
The company will complete their work as quickly as possible, and we will reconnect the fiber optics.

Tuebingen, Konrad-Adenauer-Strasse

On Thursday, January 18, starting around 5:30 PM, we will finally be able to equip our dormitories in Konrad-Adenauer-Strasse with modern technology.
For the residents, this means they will be able to use gigabit internet in their rooms afterwards.
Since we haven’t been able to implement the exclusive use of routers in Konrad-Adenauer-Strasse due to technical reasons, we will not enforce this immediately but only from the start of the summer semester (April 1, 2024).
We expect the installation to take about 3 hours, meaning you will probably have unrestricted internet access again from 9:00 PM.

Tuebingen, Schimpf-WG

There will be a maximum half-hour interruption in internet access at the Schimpf-WG. We had announced this work several times before but could never implement it due to problems accessing our hardware in the neighboring building. We cannot say exactly when this will be, but it will happen some evening between Monday and Thursday.

November 2023 Welfenstrasse

The internet at Welfenstrasse 80 is not working right now.

We first heard about this issue on November 11, 2023, after 10 PM, but the information was not very clear at first.

After checking the wireless bridge from a distance and ruling out other possible causes, we hope it’s just a loose mount on the bridge.

But, we are worried that we might need to replace it.

Just to be safe, we are sending a request today for a replacement to StuWe.

All checking and fixing work depends on the weather, because we need to go on the roof to do it.

So, we are hoping for better weather tomorrow to check the hardware in person.

As always, please report right away if something isn’t working. Describe the problem and what kind of tech you are using. We already know how important the internet is, so you don’t need to mention that. Just tick the box if you feel like saying that.

Update Tuesday 14.11.2023 6:30 pm:

In the morning, it became clear that there would be a long break in the rain, which might allow us to work on the roof in Hohenheim. That’s why we decided to have a meeting during lunch break. One of us, who was professionally near Hohenheim, was able to be on the roof in Egilolfstraße during the conversation and check the antenna there and its alignment.

Originally, we thought that the antennas had reached the end of their life and needed to be completely replaced. Getting new ones would probably have been possible by the end of the week, but in the meantime, the poor internet connection would remain. Therefore, we came up with the idea to dismantle a part of a radio bridge, which was used as a test setup, from another roof and replace it in Hohenheim today. Right after the meeting, we implemented this and around 16:50, we were able to replace the antenna on Welfenstraße, which was responsible for the disturbance. After some driving and a bit of traffic, I am now here dictating this text, which I will have ChatGPT format before I leave for the evening.

We hope that the system is now working again and plan to create redundancy soon. This way, if this pair of antennas fails, it can automatically switch to a better system.

Of course, we would prefer to have a fiber optic connection to you, as we usually do, but that seems difficult.

Update 15.11.2023, 7:30 pm:

A new day, a new attempt! Unfortunately, the exchange in Welfenstraße yesterday was not successful. Therefore, we have now placed the antenna that we had removed there on Egilolfstraße and thus swapped everything once.

Currently, there are no new outages to report, and we hope to gain some time to decide on 2 more antenna pairs. These should then be able to function in continuous operation as redundancy for several years.

Once you are in Hohenheim, such an exchange is quickly completed. The travel time alone today was approximately 3 hours.

Update 16.11.2023, 8:15 am:

Now sign of a problem since the exchange, but also no feedback from anyone who lives there.

Welfenstrasse Sept 2023

We currently think that the radio bridge might have a problem. To check this, we need to go to Hohenheim and climb onto the roof of Egilolfstrasse.

Today at 2:50 PM, we restarted the hardware and are now monitoring the transmission values. We hope the issue is due to the current weather, as the weather and our availability don’t match the necessary work.

Please let us know in the next few days about your experiences with the internet connection so far.

Hohenheim Uplink Upgrade 11:30 am till 4 pm

Good morning dear Hohenheim residents!

Today, the Uplink upgrade will be fully implemented. If everything goes well, you will be running on 10G afterwards, and the outages will come to an end.

To transport the Uplink technology from the temporary location at Schwerzstraße 2 to the new location at Egilolfstraße 57, we will need some time. Unfortunately, during this time, the Hohenheim dormitories will be offline.

Since we have to unplug the device and then reconnect it in a different building, it cannot be avoided. However, we will hurry as much as possible.

Hohenheim 26 of May Upgrade

It’s time!

Last night, we were given the task to carry out the upgrade.

As mentioned before, we had already prepared a new location for the uplink, which will enable all Hohenheim residences to go online.

To transport the uplink technology from the temporary location at Schwerzstraße 2 to the new location at Egilolfstraße 57, we will need some time. During this time, the residences in Hohenheim will unfortunately be offline.

Since we need to disconnect the device and then reconnect it in a different building, it cannot be avoided. However, we will do our best to expedite the process.

The estimated duration will probably be around one to two hours this afternoon, with several short outages as we make the necessary adjustments throughout the day, starting in the morning.

We will update this post once we have more information.

Hohenheim 16th of May

We were able to accomplish almost everything we had planned yesterday.

We dismantled and disconnected the three generations of network technology that were stacked on top of each other.

We managed to clean the room to some extent with a broom we found. Once we speak to the janitor, we will find a place for all the electronic waste (see picture).

One of the switches currently in use didn’t look promising during the removal, so we will replace it this Tuesday evening (starting from 6 PM, depending on traffic).

This means that we will need to unplug the cables of the residents of Egilolfstraße 51 to 59 again, and they won’t have internet during this time. Some rooms will be offline for about an hour, while others will experience shorter outages.

Afterward, the room should be prepared for the installation of the main network connection for the entire Hohenheim area.

The relocation and upgrade of this connection still depend on the IT department of the student services.

We hope that with this cleanup operation, we have eliminated any obstacles that could potentially further delay the final resolution of the network issues in Hohenheim.

Hohenheim 15th May 2023

In preparation for a solution to the persistent problem, we are cleaning up Egilolfstraße 57 and bringing it up to the standard required by the working group. Unfortunately, the room looks like in the pictures, so we expect it to take 2 to 4 hours. During this time, there may be intermittent network outages for certain parts of our network in Hohenheim.

We are working quickly, but you are welcome to visit us.
