Linksys PLWK400 drops Powerline connection

[pgluser]

Just wondering if anyone else with a PLW400 and PLE400 is having issues with the Powerline network dropping out after 30 minutes to an hour. I plug the adapters in and they link to one another. Everything works great including wireless internet access. After some time the powerline link drops out. I can still connect to the wireless adapter but without the powerline link between the two adapters there is no internet or network access. This happens even when the adapters are plugged into outlets beside each other. Of course the Cisco live chat person was not able to help. Not sure they understood the difference between the Powerline link between the two adapters and the wireless link to the wireless adapter.
