i started getting PS3 error 8001000b since last night i dont know if it was a update for home hub 2 but four differnet ps3's.
since last night the bt home hub 2 started blocking the ps3 on wireless and wired connections.
i have tried factory reset and connecting directly to the home hub 2
i also should add that the pc and laptop work fine.
this is an old post that may help http://community.bt.com/t5/BB-Speed-Connection-Issues/PS3-Homehub-connection-problems-error-8001000B...
you can also search the community as there are more posts
if it was a firmware fault there would be more posts on the forum than just yours
this is latest firmware which was last issued sept 2011 http://bt.custhelp.com/app/answers/detail/a_id/11585
so the home hubs dead because it shouldnt do it to all four ps3's right and not effect the pc
