Changing interfaces config


Good day. I have a small network/lab in my room which i am using for my CCNA certification. I have a Windows 7 laptop, a raspberry pi, a box with xubuntu, and an older laptop with LXLE all connected to a cisco switch. I have been sharing my win7 laptop's wifi connection with my raspberry pi and its been working great. However, both the xubuntu box and the other laptop with LXLE are BARELY connecting on wifi and it's too far for me to run cat5 cables to the router. So i figure i'd try using the raspberry pi set up:

sudo nano /etc/network/interfaces
iface eth0 inet static

address 192.168.1.xxx
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1


This worked GREAT for both the xubuntu box and LXLE. I was able to do updates and download to both machines......until i had to reboot. After a reboot, the connection managers on both linux machines said "Device Unmanaged". It was only AFTER i removed the configs from /etc/network/interfaces and rebooted that they went back to normal. Any way around this?

Any help would be most appreciated.

Thank you.

Hey thanks for responding. Turns out, the Cisco 3550 that I am using was just taking its sweet time to bridge the connections for some reason. I removed the configs i made to etc/network/interfaces and set everything to default. Fired up the old laptop with LXLE, the tower with ubuntu, and a raspberry pi with raspian and sh ip int br on the cisco shows interfaces "up" and pings were successful. All the hosts i have successfully used the main laptop's wifi connections seemlessly. Thanks again!
