Re: [Discuss-gnuradio] 802.11a capture with HackRF - Why am I not receiving signals anymore?

Do you mean with a spectrum analyzer? Forgive me if that's a dumb question, I'm a bit new to this.

The max bandwidth of the HackRF One is 20MHz, so I should be able to receive data.

I'd recommend looking at the spectrum you receive. Also, how does
receiving a 20 MHz wide channel with a HackRF work? Wasn't the maximum
bandwidth of that lower?
