Re: DGND3700v2 – N600 Wireless Dual Band Gigabit ADSL2+ Modem Router....Need advice on an extender

I live in a condo (825 sq ft) w/my router in a back room. I use my laptop in another room maybe 150 ft from the router and lose connection more then I like, buffering problems etc. I would like to purchase an extender but need advice on which  extender to purchase.
