wireless connectivity windows 8

On my windows 8 dell Vostro 1520 my wifi was working well up until one week ago. Problem now is the network is acting up.

My wifi printer and chromecast device are not connected anymore.

Haven't changed anything with the network settings, can't remember installing anything that would explicitly change network settings.

Managed to use the printer by connecting the cable but my chormecast device is useless now.

Tried restarting the wireless router, laptop, printer/chromecast device but nothing helps. Also disconnected and reconnected the wifi connection on the laptop, but nothing seems to help so far.

I'm able to browse from the laptop. The problem is only with connecting with other devices namely printer and chromecast, which used to work before.

How do I trouble shoot?

thanks!

Connect your wireless computer to the router by wire (so not wirelessly). That divides the problem in two. With a wired laptop connection, what happens to the other devices?

Likely suspect based on your description: The wireless router has had a problem.

Document the settings on your wireless router, do a HARD reset back to factory specifications, check for a firmware update and then set it up again.

Another possibility: IP Conflicts. The printer could have changed IP, so set it up statically. I do that for most printers. The chromecast device could have changed IP addresses and created a conflict.

Turn the Chromecast device OFF (all the way), turn off the printer, set up the router, add the computer wirelessly, add the Printer with a static IP address on the network and then add the last device. Does it work now?
