I have a peculiar problem with my home network.  I have a Linkstation LS-XHLD87 NAS unit and an iMac that can't seem be on the wired network at the same time without bringing the whole thing down.

 

The set up consists of an Actiontec GT701-WG (DSL modem/wireless router) with a single ethernet port that I have running to a 5-port megabit Netgear switch.  The devices hanging off the switch are the Linkstation NAS and a Sonos bridge.

 

I'd like the iMac to be wired to the switch too, but if the iMac and Linkstation are both plugged in all of the lights on the switch go off and the network shuts off - while the Actiontec ethernet light blinks without end.  If I unplug either one the network comes back up.

 

I'd prefer to have both plugged in and I'm wondering what setting on what device (iMac, router, Linkstation) I should look to to fix this? The only thing I could think of to check was the router DHCP settings, which shows the range 192.168.0.2 to 192.168.0.254. The Linkstation and mac are both set to use DHCP also.

 

Lastly, all hardward is plugged into the same power strip and no shielded ethernet cables are in use.

 

Thanks for any suggestions!

iMac (24-inch Mid 2007), OS X Mavericks (10.9)

    Make  sure you are using the correct cables, i.e not crossover cables, although many switches auto sense it may not in this case.

     

    Likewise try fixing the port speed to 100Mbs on both the NAS and Mac, again it could be auto sensing of speed that is the problem.

     

    I know the Mac supports Gb, I do not know what your switch and NAS support. If fixing the speed cures the problem and the units support Gb then try it it with the ports fixed at a Gb.
