My GF's computer gives this error message when running ipconfig /renew

I have just replaced my wifi router with a wired ethernet switch (we live 2 blocks from a college and keeping wifi secured was proving impossible.) I have wired up all three computers in the apartment, and hers is the only one having an issue contacting the internet.

So far I have: Run ipconfig /flushdns tried to run ipconfig /renew (sits for about 2 minutes before spitting out error message in title) confirmed settings on adapter in windows (Windows 10 if it matters) Disabled/re-enabled ethernet adapter run the following commands (gotten from a tech-support site)

netsh winsock reset catalog netsh int ipv4 reset reset.log netsh int ipv6 reset reset.log

Rebooted computer Rebooted switch Rebooted modem
