thinkpad x230 debian 9 weak wifi

Hi,
Just installed debian 9 on x230 with intel N6205 wifi card. Followed all the infos for improving weak wifi.
/etc/modprobe.d/iwlwifi.conf contains the following:
ptions iwlwifi led_mode=1 power_save=0 11n_disable=8 swcrypto=1

#led_mode:0=system default, 1=On(RF On)/Off(RF Off), 2=blinking, 3=Off (default$
#power_save:enable WiFi power management (default: disable) (bool)
#11n_disable:disable 11n functionality, bitmap: 1: full, 2: disable agg TX, 4: $
#swcrypto:using crypto in software (default 0 [hardware]) (int)

However nothing is changed, wifi signal is still very weak. There is an W7 running on the same laptop. With that OS wifi signal is excellent. Is there a way to improve?
thanks

This hardware supports both the 2.4 and 5gHx bands

In general, 5gHz bands are stronger and less congested - the symptoms you describe could result from Windows using 5gHz and Debian using 2.4gHz
