There are two kinds of wireless range extenders:
Store and forward, AKA WDS
In-band repeaters.
You don't want store and forward for VoWLAN ( WiFi Phone ). Store and forward captures data packets headed one way, stores them in memory, then repeats them. Then it does the same thing for packets headed in the other direction. This causes a reduction in throughput. Massive delays, choppy bursts of data; incompatible with voice. Store and forward is a one-piece unit.
What you want is a bridge acting as a client for the hotspot, feeding an AP on a different channel. Data comes in one radio and goes out the other.
This also causes a reduction in throughput. But it does not cause delays and chop up the data stream at random.
You would want to set QoS ( Quality of Service ) in both bridge and AP, to give VoWLAN packets highest priority. A side effect of using an in-band repeater would be better reception for your laptop.
One of these:
Linksys wireless bridge
With one of these:
Panel antenna
Feeding one of these through a CAT5 cable:
Linksys AP
I would use a wireless router instead of an access point:
Wireless router
Wireless router does everything an AP does and much more.
