If your AP is reachable over the network, you can connect to it with SSH (Secure Shell). Console cable is only needed if the AP is unreachable, or does not come up properly for some reason.
Or even run it through the WebUI:

I'm still wait for the console cable I ordered so I can able to do the setting with CLI. Likewise, I have no knowledge of commands used for this specific configuration.
Thanks

Loni,
What regulatory domain (country) are you in? Are 160MHz wide channels permitted?
Thanks,
Brad

I'm unable to enable 160GHz on Aruba 555 using the Aruba GUI, so if anyone knows how to do it, please let me know.
Thank you in advance for any help you may provide.
