Finally, my first post! Hopefully I haven't messed this up.
Spotted this little Range Booster today at Australia Post, figured at $9.99 it's a steal. Not sure if this is nationwide etc as I can't find it online.
Personally, I'd price match at OW just to save that extra dollar. Your stinginess may vary.
Enjoy :)
Don't expect much from WiFi Extenders/Boosters.
Most of them are nowhere near 50% efficient. So if you have a WiFi deadzone where you get a signal strength of 10%, a boost of less than 50% of that, is not going to unlock lightning speeds for any devices in that area.
EOP/Powerline Adapters cost more, but will give you a more guaranteed, consistent result and are the next best thing to wiring your house with CAT6.
