simultaneously to the network to do some tests, so that some PCs can
connect to the internet through the Linksys and the others from the
Cisco.
Although at first it seemed to work, people started complaining that
the internet connection through the Linksys was unstable.

RIP is active on the BEFSR41 and probably cannot be disabled on it
(except possibly by disabling routing mode, which would disable NAT.)

The above RPI theory is worth checking out.

Also you may wany to turn off Proxy ARP on the cisco.
And maybe ICMP redirect too?

conf t
int [inside-one]
no ip proxy arp
no ip redirect

(from memory so may not be exact)

If you wanted, you could check the routing tables and
arp caches on the various devices to see
if they have what you expect

cisco:
sh arp
sh ip route

windows
route print
arp -a

before blindly turning thing off.
