I need a range extender in the $100 price range, with detachable antennas. The area I'm trying to reach is above a ceiling with plenty of metal in it. I tested and need at least 8db antennas to get 2 bars of signal.
I already tried with a TP-Link TL-WA830RE, but looks like I got a defective unit (see here
for the thread).
Can you recommend, from personal experience, a reliable repeater that fits the requirements?
