Could be several things.

1)  If using DHCP ...

DHCP Server (on router?) does not like the client requesting a new
DHCP lease different than its prior and/or expects the client to
request the same address, denying it if it does not.  I.e., Linux and
Windows don't know each other DHCP leases.  If you are in Windows far
more than Linux, statistically this could be the reality.

2)  If using UPnP ...

The UPnP (Router) could have some settings sent by Windows that Linux
does not, and the Router does not like.  This could include everything
from Windows proprietary / non-IETF DDNS for hostname to countless
other things not supported by IETF Zeroconf but only proprietary
Windows services.

In general, take a look at your router's settings and see if there are
some advanced services that may be Windows proprietary.  Otherwise it
could be as simple as DHCP lease settings/expectations, that the DHCP
server expects the DHCP client to send a request for the same IP if in
the lease window.
