Share 2.4 GHz frequency from the same adapter connected to 5.0 GHz

[dvdesolve]

I have the following Wi-Fi card on my nettop: [3.511768] iwlwifi 0000:02:00.0: Detected Intel(R) Dual Band Wireless AC 7265, REV=0x210

I can connect to 2.4 and 5.0 GHz networks successfully and share connection via the same card in 2.4 GHz mode. Now I connected to 5.0 GHz network and want to share internet via 2.4 GHz. My command is: sudo create_ap wlp2s0 wlp2s0 -c 1 -w 2 --ieee80211n --ht_capab [HT40+][LDPC][SHORT-GI-20][SHORT-GI-40][TX-STBC][RX-STBC1][MAX-AMSDU-3839][DSSS_CCK-40] --country US SampleSSID SamplePasswd --freq-band 2.4

but I get the following error:

Config dir: /tmp/create_ap.wlp2s0.conf.KsVGb2e4
PID: 8093
Network Manager found, set ap26 as unmanaged device... DONE
wlp2s0 is already associated with channel 36 (5180 MHz), fallback to channel 36
Creating a virtual WiFi interface... ap26 created.

ERROR: Your adapter can not transmit to channel 36, frequency band 5GHz.


Doing cleanup.. 

Can create_ap be used to share connection via the second band?

wlan cards can only work on one frequency at one time
