My ipad and my iphone wont connect to the wireless,

Consider the HRpart Wireless HDMI Display Adapter. Here are the key details:

4K Screen Mirroring: This adapter allows you to view audio, video, and office documents from a small device (like an iPhone, iPad, or MacBook) on a larger screen (TV, monitor, or projector) without messy cables. It's perfect for presentations, meetings, and exhibitions.

Wireless and Easy Connection: Setting up this wireless HDMI adapter is straightforward. You'll need a 5V/2A power source (which can often be provided by a USB port near the HDMI input on modern TVs and projectors). If the port is occupied, a battery pack can also work.

No Need for Wi-Fi: The adapter is self-contained and doesn't require an internet connection. Once connected to an HDMI input and powered, it displays a helpful screen for easy connection. You can stream movies, videos, games, and office files from your Apple device to a high-definition TV or projector.

Compatibility: This device is more suitable for Apple devices, including iPhone models (such as iPhone 7 Plus, iPhone 8, iPhone XS, etc.), MacBook Pro, MacBook Air, and various iPad models (iPad Pro, iPad Air, iPad mini). However, please note that it does not support HDCP-protected applications like Netflix, Amazon Prime Video, Hulu, and others.

You can find this HRpart Wireless HDMI Display Adapter on Amazon 1. Keep in mind that it's designed specifically for Apple devices and provides a convenient way to mirror or cast your screen wirelessly.

Depending on your browser, download or display the pdf of the WNR2000 manual ( http://documentation.netgear.com/wnr2000/enu/202-10397-01/pdfs/FullManual.pdf ). The manual might also be found on the CD that came with the router.Follow instructions Chapter 2 Page 7 to enable/setup WPA2-PSK (AES).Make sure you SAVE/APPLY the settings before proceeding. Follow instructions Chapter 2 Page 17 to Disable Router's PIN. When you do, make sure you leave the box checked to "Keep Existing Wireless Settings".Make sure you SAVE/APPLY the settings before proceeding.Here's a work-around ff the above doesn't fix the issue for you. Sorry I don't have iPad-specific instructions, but I don't have access to an iPad/iPhone at the moment. I've done the following on iPads, iPhones, Android phones and tablets, Windows phones and PC's - it works on virtually all Wi-Fi-capable devices..:
Instead of letting your iPad find the network and trying to connect with the password, try manually creating a new Wi-Fi network connection by typing in your Wi-Fi network name (SSID), selecting WPA2 (AES) encryption and entering the Wi-Fi password your configured in STEP 2 above.Please note: You'll have to forget the Wi-Fi network in your iPad's settings if you keep your Wi-Fi network name (SSID) the same as it is currently.

What do you mean exactly by hot spot?

To charge an iPad you have to connect the USB cable to iPad power adapter (12W in power and is bigger in size compared to iPhone's). If you connect it to iPhone power adapter you might see that the iPad is not charging, but will take a very long time to charge. The same goes with connecting directly to computer.

Also, there is always a chance that either your cable, or adapter or the iPad itself has gone bad.

Hold the power button and home button down together for 10 seconds, or until you see a white apple.

If you reset the router and have not turned off and back on all your devices you probably have conflicting addresses. some versions of ps3 will not connect for some reason unless they have the first ip available on the router.
Turn off your wirelss on your iphone and ipad, turn off the ps3. Reboot the router when it comes back up turn on the ps3 and get a good connection, the enable wireless on your ipad or iphone and get a connection the doe the same with the other.
This will avoid conflicting addresses.
An IP address has a 24 hour lease if you reboot a router it forgets what device had whipch ip address. If you need to reboot your router you need to refresh the ip address of all your devices to avoid conflicting ip's.
In this case I suspect you ipad and iphone are attempting to use the same ip address.

Go to the linksys website, see if they have a firmware flash for the router, that may help in some connectivity issues. You may also find that the ipad/iphone may drop connections when battery levels are low

iPad and iPhone have some limitations regarding bluetooth connectivity. I believe you will need an external application depending what do you want to do.
