I own a Coolpad Surf hotspot which provides an internet connection to my desktop computer via WiFi. In the browser interface, I can select a WiFi channel in the 2.4 GHz band, but I see no option to select a channel in the 5 GHz band. I wonder if that is because my desktop computer does not support 5 GHz WiFi. If I buy a USB WiFi adapter that supports 5 GHz WiFi and plug that into my desktop computer, will that cause the browser interface for the Coolpad Surf hotspot to show that WiFi channels in the 5 GHz band are available for use?
Hey Steven! Based on the device specifications, it will only connect from 802.11 b/g/n to 2.4GHz.
I refer you to the specification for 802.11 /n, linked to below. It states
"IEEE 802.11n-2009, commonly shortened to 802.11n, is a wireless-networking standard that uses multiple antennas to increase data rates. The Wi-Fi Alliance has also retroactively labelled the technology for the standard as Wi-Fi 4. It standardized support for multiple-input multiple-output, frame aggregation, and security improvements, among other features, and can be used in the 2.4 GHz or 5 GHz frequency bands."
So, that is why I asked the question. Will access to 5 GHz WiFi channels appear in the browser interface to the Coolpad Surf hotspot if I equip my desktop computer to operate on the 5 GHz WiFi band?
I don't think it will access to 5 GHz WiFi channels because it only supports up to 2.4 GHz, even if you equip your desktop computer, at the end of the day, it is the device "Coolpad Surf" that we are talking about, and based on the specifications it only support up to 2.4 GHz.

Where does it actually say that? From the Coolpad web site, the page at
the specifications state:
Wi-Fi Specs: 802.11 b/g/n
Max Wi-Fi: 10 Users
USB Type: Type A Micro USB
SIM Type: Nano SIM
Card Slot: No
There is no mention of WiFi frequency band, but it does state that it complies with 802.11 b/g/n, and 802.11n includes both 2.4 GHz and 5 GHz bands. Is it your opinion that the Coolpad Surf hotspot does not support the 5 GHz WiFi band, or do you know that to be a verifiable fact?
You can be able to locate this information on the user guide of the device. Do you still have the box or the user guide by any chance? Here is the link here keep in mind that when the manufacture make a device they made it depending on the carrier specifications.
