Yes, the external antenna now works as expected.
I didn't measure the exact range, just made a simple comparison test between two ESP-201 modules with different antennas. Seems the external antenna performs a few dB better than on-board one.
Measuring distance - approximately 7 meters
X-axis - time
Yellow line - ESP-201 with external antenna
Blue line - ESP-201 with on-board antenna
