 TX underrun -- increasing TX threshold  The device generated a
 transmit underrun error while attempting to DMA and transmit a packet.
 This happens if the host is not able to DMA the packet data into the
 NIC's FIFO fast enough.  The driver will dynamically increase the trans-
 mit start threshold so that more data must be DMAed into the FIFO before
 the NIC will start transmitting it onto the wire.

 Acho que não é isso que está causando o problema.

 Existem duas máquinas com o mesmo IP na rede... verifique de quem são
essas dois MACs e se os APs estão com algum esquema de proxy ARP.
