Please note: networking components such as Powerline adapters require that all adapters must work within the same Home Plug standard to remain compatible, for example Home Plug AV (HPAV) adapters with communicate with other HPAV Powerline components, regardless of whether they are 200 Mbps or 500 Mbps. Older 85 Mbps adapters work on the different Home Plug 1.0 standard & are not compatible with Home Plug AV adapters. All Powerline products will connect to any switch or router Ethernet port. Powerline adapters can be used with extension leads (except surge protection ones), & will work across different ring mains so long as they share a common fuse box.
