I just upgraded from 16.10 to 17.04 and I started to have network problems when connected to my office's network.
I can connect to my office network with eth or wifi, both ways are working well by themselves. But with 17.04, if I have wifi connected at the same time as the cable, the network is extremely slow. If I disconnect any of them, the network is fast as ever.
Both methods connect to the same network (in my case 10.10.1.0/24). I have dhcp assigning me fixed ip addresses based on mac address.
Having read this thread, I just ran software-updater, but I was already up-to-date.
My network-info is pasted here.
Any ideas on what should I look for?
