I have my discs connected through powerline adaptors and they worked really well but If i can't get them working again i'll send them back and try what you recommend as the 600 looks really good.
Could it be the powerline adapters giving the problem? You could connect a laptop to the end of the adapter, and see if you get a connection.
Bear in mind that the hotspot 600 and similar, use the Homeplug AV standard, and they may nor work if you have other powerline adapters of a different standard.
Anyway, better keep things on topic.
I get the same issue with the disc connected directly to the hub so unfortunately it's not the powerline adaptors.
Whether by luck or not, the testing I'm doing with the Xbox connected via WiFi rather than Ethernet on one of the subbordinate discs, the connectivity has remanied up for about 4 days and counting so far.
I'm not sure if this is the complete answer as there is a poster above having problems and he didn't have any devices connected via Ethernet.
Couple of things . It is only some of my devices that are affected as well, but the majority of them. It is only two windows laptops that aren’t affected.
The explanation that the reset method outlined to you prevents firmware upgrading from one disc to another doesn’t make total sense. Once firmware is upgraded that is it until a formal upgrade or back Rev. Resetting shouldn’t downgrade it again. The method you have been given should prevent duff config recopying from one disc to to another that has just been reset.
