I have just bought a Seagate FreeAgent GoFlex Home but it is slowing down my network at home. I have backed up my Mac to it and did this with the ethernet cable as it was going to take over a day with Wi-Fi, but now that is done whenever I or anyone else at home tries to browse the internet, pages take forever to load up or won't load at all, I have a Netgear DGND3300 wirless router. Is this symptomatic of having a NAS as part of the my set-up or I have got a bad NAS drive ?
