I've been slagging off my iPad and iPhone because they have not worked in some areas of the 3 storey house - e.g. lounge and kitchen. The two areas I most wanted to use the things!
A Toshiba netbook worked fine, so I thought it must be the Apple devices. However, a Sony BluRay player could also not pick up the signal, so it seemed that Sky WiFi reception was marginal in the key areas. The router is on the top floor, lounge is 1st floor, kitchen is ground floor.
I bought the Netgear WN3000, hoping it would help this situation that has been going on for over a year.
The extender arrived extremely quickly. I had to use the iPad to make a manual connection between the extender and the router, and this was simple and immediately effective.
I now have a strong signal all over the house.
Unfortunately, the Sony BluRay sees the extender, but won't connect. It may be because the router password is all capitals, whereas the Sony has no facility to create caps. I'll use an Apple HDMI connector to link the iPad to the TV so I can use BBC iPlayer.
The WiFi signal had been such an annoyance, and so easily sorted!
UPDATE after a few days of use
The extender and router can be powered down overnight and both resume their excellent complementary service on power up.
