Hi there

Just a note that may help others in this situation. The WGR614 v3 has only one antenna and the problem can be in large warehouse type buildings made of steel and concrete, because of the amount signal reflections of walls and other objects, causing data corruption. If you have 3 or more computers communicating at once and you start to get some corruption and re-transmissions they can escalate and cause some routers to go very slow or even crash. One solution is to try a router with diverse antennas as these are more tolerant to situations where there are alot of reflections as the two antenna are at least one wavelength apart and the access point will be able to choose the best antenna to receive data on for each transmission.

good luck
