Gazebo 9.5 drops internet connection

Hi everyone,

I'm about to hit my head against a wall as I don't understand how this is possible.

I just started Gazebo (version 9.5.0) and I wasn't able to load models from the online database. So I went online to search for models manually. That's where I noticed that my internet connection dropped.

After checking, this happens as soon as I start gazebo. When I close gazebo, the internet connection comes back...

I can't figure why this happens, as it doesn't happen on my colleagues' computer (on the same network and same version).
I also tried to uninstall and reinstall gazebo9 with sudo apt remove gazebo9; sudo apt install gazebo9.. and it still happens

Do you have any idea on why this happens and how to solve it?

How are you checking that the connection is dropped? Could it just be slow?

@chapulina simply by loading a webpage, or even doing a ping in a terminal.

Hi, I had the same issue and solved it by changing the way I access internet.

More specifically : I have a router provided by ORANGE (french internet provider) and I was not able to launch gazebo because it could not download the model. Then I disconnect my PC from the WiFi of the ORANGE router and I connect in WiFi to my 4G smartphone connection instead and it worked. Later, I also moved to another house and it also solved my problem so I am pretty sure that this problem is associated to my router.

Why : No idea, I know nothing about this kind of stuff and just got lucky to find a fix to my problem. Maybe some firewall issue.

My guess is that the internet becomes slow while Gazebo is trying to download models from the database... You can try cloning gazebo_models and installing it so Gazebo doesn't try to download the models at runtime. Something like this:

mkdir ~/.gazebo/models
cd ~/.gazebo/models
hg clone -b default # this may take a while
