NAS Linkstation Giga - Disruption of network and internet

[masslbp]

   

Small office with a basic setup:

 

-5 macs

-1 PC

-Highspeed >>G wireless router

-network printer

-NAS Linkstation Giga

 

With the NAS unplugged the network runs fine. With it plugged in the network goes up and down. Some computers loose connection. Unable to connect to NAS at times as well. The ping rates stall out. A their is a no route to host message - sometimes.

 

Please help! This has been a 4 month issue and I am totally out of ideas.

The newest firmware is http://www.buffalotech.com/support/getfile/hd-hglan_161.zip

 

I would try to update the firmware directly connected from a desktop to the linkstation.  See if it takes the firmware, or if you have any of the same problems when directly connected to the computer.  You might have to reset the device when doing a direct connect to see if you can get an ip address of the device.  Use the nas navigator to get the ip address and then set a static to that desktop (pc) with a different last octate.
