A communication device may receive a first request packet from a first device and receive a second request packet from a second device. The communication device may send a first response packet to the first device in response to the first request packet and send a second response packet to the second device in response to the second request packet. The communication device may decide a timing for sending the second response packet to the second device. The timing may be decided such that a time period from receiving the second request packet to sending the second response packet in response to the second request packet is longer than a time period from receiving the first request packet to sending the first response packet in response to the first request packet. The communication device may send the second response packet to the second device at the decided timing.
