Can't get wifi set up on laptop

[btse1]

I picked up a used Compaq Presario CQ50 laptop w/ Windows 10 rather cheaply but cannot figure out how to set it up for wifi. Everything else on it seems to work just fine.

I double click the Google Chrome icon on the screen and I get "There is no internet connection. Try checking the network cables, modem and router."  But the router is working because our other devices function just fine. How do I check the modem on this model?

Under Windows Network Diagnostics, it instructs me to "turn on wireless capability" but I don't know how.

Any assistance greatly appreciated!

Did the vendor say it works with Wi-Fi?
Perhaps he did not tests it for Wi-Fi Internet.
Do you have a user guide for that laptop?
From HP:

Support for the following WLAN formats:
● Atheros AR9280 802.11a/b/g/n
● Atheros AR2425 802.11b/g
● Broadcom BCM4312 802.11

Look in the device manager and see if the wireless device is working.

It was a private sale, not a commercial vendor (not that it matters). He did say it would connect to the internet. It was cheap and I decided to take a chance.

Thank you for the link to the manual!

hEE IS AN IDEA.
Here is an idea.
Get a Ethernet cord and co0nnect it from the laptopto your router or modem. The turn on the laptop.

You might also have to restart the router, but that should not be needed. Expect to wait about 3 minuets for the laptop to make the Ethernet connection the first time. After that it is much quicker.

Windows 10 ought to easily find the internal Ethernet connection. Once you have that, you then can download things that will help you find the problem.

Hope it works. 

EDIT: Forget to mention. Windows 10 just loves to get updates. After being off of the Internet for more that a week or two, it will likely find updates for things. Be patient. You should already have made some kind of recovery media  just in case an update ruins things.
Create a recovery drive - Windows 10 help

Under Windows Network Diagnostics, it instructs me to "turn on wireless capability" but I don't know how.

On that system the wireless is toggled on and off using Fn+F12, or Just F12 (depending on the keyboard configuration). There should be a tiny light near the key- it is white if wireless is on, and amber/yellow if wireless has been disabled.

You could also always spring for a USB dongle...'bout 20 Bucks.

I had a similar problem with a Netbook - I couldn't get wireless to turn on, but I remember the manual told me to hold down the Fn key and rapidly press the F11 key at the same time.

A few things. Make sure wifi is toggled to ON. Download the drivers from COMPAQ for your model. When I googled your model it said it ships with Vista,IF your version of Windows was a clean install it would not have come with proprietary drivers so download the drivers,additionally the CNET specs said 802.11 g/b no "N". If these speeds are not acceptable then purchase a "reputably branded'' usb network adapter like CISCO.
