# Troubleshooting
## Really slow internet
I realized that the [[git]] commands `git fetch` or `git push` were extremely slow (several minutes). And it was because of a slow internet connection. The ping of google.com was like 64000 ms or so. The problem in the end was that the cm4 was using the `wwan0` interface (which is our LTE connection) but the antenna was not connected. I was surprised that it even found a network at all.
The solution was to either connect the antenna, or to take the network down with
`sudo ip link set wwan0 down`.
