Windows 7 laptop not connecting to wireless networks

[DSEV]

Hi everyone..I am having a wireless issue on my laptop. I have had my connections in the two locations for months now. One network was recently upgraded to another router and the other network router was reset. I am at the location where the router was reset. My available networks are showing and are in excellent strength but whenever I hit "connect",nothing happens.I don't even get a prompt to enter the passcode. I even tried to connect at my local library's wifi with no such luck. When I run diagnostics it keeps saying "None of the networks you have previously connected to are in range"?? My drivers are up to date. I am a novice when it comes to computers so I really need help on this one. Just tell me what is needed in terms that I can understand (again, I am not that computer savvy,lol) and I will provide them. If it's of any help, I am running on a 32bit and my laptop is a HP. The router is a Broadcom 4313 802.11b/g/n

Hi DSEV, welcome to Seven Forums.
First, make sure your new router is set as per your ISP's settings.
Now,
Step 1. Close all applications that use the network — browsers, e-mail, chat, video, weather, and any other app
that might be automatically updated in the background.
Step 2. Click Start, type device manager in the Search box, then press Enter.
Step 3. Browse to the list of devices and click to expand the Network adapters section.
Step 4. Right-click on the first adapter under Network adapters and click Uninstall. Windows will ask whether you
want to remove the associated device drivers; say no, you want to keep the device driver. Repeat for all network
adapters on your system under Network adapters.
Step 5. Close Device Manager.
Step 6. Reboot.
When you reboot, Windows will think it’s found new networking hardware and will set up fresh connections. By
the end of the reboot, your Network should be back and running in streamlined, trouble-free form
