The dorm went offline Friday morning ~10 am.

The reason is probably overheating.

The StuWe-IT decided to solve the problem themself and will solve the problem on Monday or Tuesday.

Update 30.05.2022 13:13

die Störung wurde vorübergehend beseitigt und Bewohner die sich per Mail gemeldet haben entsprechend informiert.
Zu einem späteren Zeitpunkt werden zur dauerhaften Lösung vor Ort Verkabelung und Stromanschlüsse geregelt angefasst, sowie andere Geräte verbaut werden.

Update 22.09.2022 8:55

Big parts of the buildings are offline.

The case is still in the hands of the StuWe-IT, the Netz-AK has no access to the devices and can not help you.

We did inform the StuWe and wish you luck.

Dropouts in 2.4 GHz Wi-Fi

Avatar photoHeinrich on

The reason why we do not recommend routers that do not create a 5 GHz Wi-Fi is very simple.
There are twelve channels in the 2.4 GHz frequency range, which means that theoretically a maximum of twelve such Wi-Fis can co-exist. In practice, a maximum of four 2.4 GHz Wi-Fis will work side by side without interfering with each other excessively.
2.4 GHz penetrates walls very well, but can transfer data less fast.
For dorm rooms a 2.4 GHz Wi-Fi is therefore very likely to suffer from interference and dropouts if you have more than four neighbors within a distance of 30 meters around you (even above and below you!).
A bad Wi-Fi okay for WhatsApp and surfing, but not for videoconferences.

We will replace some hardware today.

We will wait till 1:30 pm to interfere as little as possible with your courses.

The new hardware will not allow the usage of access points and repeaters any more, but we can offer you a workaround till end of semester.
Just contact us, after consulting the tutorial for Wi-Fi.

Failure 21 Oct 2021

Avatar photoHeinrich on

140 optical fibers have been separated during a bridge demolition, as a result the Französische Viertel is offline and all the dormitories that are connected over it, i.e. Eugenstraße and Hechingerstraße.

The repair starts at 0:00 am and is scheduled until 5:00 am.

If you are not back online in the morning restart your router.

We have nothing to do with the demolition of the bridge, nor with the repair of the fiber optics. Let’s hope the guys and gals who are fixing it tonight do their job well!

One night without internet is not nice, but …

Update 8:56 pm: Since half an hour the Französische Viertel is back online. Eugenstraße followed, we are waiting for the Hechingerstraße.

Update 8:29 am: Between 8 and 10 pm all dorms went online again. Thanks to our local fiber optics company TüNet!
In case you missed stuff at university and need to proof that it was not your fault, contact us.

We will arrive at 4pm and start installing the hardware.

Today is the only possible day to do this kind of work, if it is inconvenient, sorry.

The dorms in the Kaiser-Wilhelm-Strasse will be offline twice for a maximum of 10 minutes each.

If just your room stays offline after that, contact us immediately over the contact form. We`ll stay in Geislingen for a while for cases like that.
(Give us a phone number and answer the call from the blocked number, that’s us!)

WiFi died March 2021?

Some of you did build their own WiFi in a way that blocked the internet access of others in our house. Using access points or repeaters to create a WiFi is not allowed in our network, because it keeps others from getting online.

Only routers are allowed to build your own WiFi, as we stated in our manual. We stared enforcing this rule in all our dormitories because it`s necessary.

To get you back online as quick as possible, please look up your device in our manual. Is it marked “ja”, you can just configure it in router mode and you are online again. If you are not successful, you can contact us using the contact form and the subject “Creating a WiFi”.

If your WiFi device is marked “nein” and you contact us, we will try to find a solution for the time you need to replace the device.

Contact and announcements

NetzAK_Aushang_Stand_WS2020 should be displayed in the entrance of your house.

The Netz-AK is announcing all its changes to the dormitory network on its website.

For us it`s important to have latest version of the notice in our dormitory, so you can reach us directly with no delay.

If the notice is missing, you could just print it yourself and pin it in the entrance to you house or you contact your dormitory administrator and ask them to do it.

We are aware of the problem that some old versions of our notice are not getting replaced. You must report the problem to your administrator at the Studierendenwerk to hopefully improve the situation.

If you contact us using the contact form, most problems can be fixed in a few hours as long as you are in the dormitory and respond to our emails.

Because we are volunteers, we are never off duty and we respond quickly.

As volunteers we are using our private phones, that`s why we call from blocked/ private/ anonymous numbers, so please just answer these calls after reporting an issue.

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.

On Tuesday the 15th of October [2019], we were informed that there are problems for people getting online in the afternoon.

The reason for this is simple. More than a few people were creating their own Wi-Fi by using repeaters and access points instead of routers.

To ensure everyone to be able to access the internet we are since today disabling the ports in the rooms that are hindering others to get online.

To get the port enabled again, please contact us by our contact form.

We need to know the kind of device you connected to your wall socket. Is it on this list?

Some people moved their devices from one blocked room to the next. This rooms have been blocked today (21th of October [2019]). Every room using more than one IP will be blocked.

As soon as you contact us and promise to not connect the the misconfigured device to our network again, you`ll be unblocked. This is necessary to ensure that everyone in the house has the possibility to get online.

Today (Sunday the 27th of October [2019]) we`ll unblock all the ports and see what happens. If you experience problems, please contact us.

Update: 26. October 2021 we had to deactivate rooms again.
We will replace our hardware soon. After that only routers will work and further problems will be prevented.
Update 27. October 7:45 am: We will replace our hardware this evening. All rooms will be activated again, but will not be online with their current setup.
Update 27. October 10:00 am: So far no one has contacted us!
Update 27 October 1:10 pm: Still no feedback, but since enough bad devices were removed from the wall socket, all rooms could be reactivated without currently endangering the network for the others.
Update 2:10 pm: Reactivating the rooms probably kicked the main network connection at 1:40 pm. If we don`t find a Hausmeister to restart the switch manually, the houses will be offline till we replace the hardware in the evening.
Update 5:50 pm: Leaving Tübingen.
Update 10:00 pm: Back in Tübingen, next try tomorrow.
Update 28th 10:20 pm: since 4:30 pm new hardware up and running
