As I wrote before this is can't be a software problem with Remote
Buddy. With absolutely no code in Remote Buddy that could cause any
packet loss, it really can't cause it. Remote Buddy doesn't change
your network settings, nor does it do anything with your network
adapter(s) - including AirPort at all. Even if you enable AJAX Remote,
all it will do is do a default listen() on a standard TCP/IP socket -
something every server has to do and fully standards compliant, not to
mention it's many, many abstraction layers away from any piece of
hardware.
It must be either a problem in Apple's drivers or - and I believe this
to be more likely - a physical interference between Bluetooth and
WLAN. Even if you don't have a remote control paired / connected,
Bluetooth will still send packages in an attempt to find and connect
to known devices. If it would not do this, you couldn't just press 1 +
2 together to pair but you had to go through the pairing process
manually each and every time you want to use the remote control.
I can't do more for you than advise you to try setting up your WLAN to
use a different frequency or disable Bluetooth while you want to use
WLAN.
You may also want to check this thread on Apple Discussions where
users report about the same problem:

For them, changing the base station brand or disabling Bluetooth did
the job.
