I have 40/10 fibre connected through the SKY SR101 Hub. I would like to improve the wireless speed and strength.

Would the addition of a range extender do what I want? Do I need and thing special as my Hub reports my network type is mer.

I have seen the following:
asus EA-N666 N900 gigabit 3-in1 Range Extender
TP-Links TP-WA850RE Universal Wireless N Range Extender
Edimax N300 Range Extender
Netgear DB WiFi Range Extender
Belkin N300 SDB Range Extender
