Hello, may I have the model number of the Jio fiber modem or router? Is it dual-band or only support 2.4GHz?

Can you see its wireless network when installing this adapter on the computer successfully? BTW, what is the operating system of the computer? Please ensure you are running the latest driver on it.

If you can see other wireless networks but cannot find your own, try to change the wireless settings on the Jio fiber modem/router, such as adjust the wireless channel and channel width on the wireless router, such as channel 11 for 2.4ghz; channel 36 for 5ghz, this which may help to improve the wireless connectivity and range.

Good day.
