Router wi-fi won't connect to some devices

I have an Asus router (a good one) which is hard-wired to 4 devices. It also has wi-fi turned on - both on 2.4GHz and 5.0GHz bands. My iPad and an iPhone connect to both bands with no problem. However, I can't connect to my Android smartphone or a PC laptop on either band. Both of these devices are quite close to the router. I can see where these devices are trying to obtain an IP address - but once they do, they immediately disconnect. Possibilities?

Thanks, Ken. Unfortunately, it will probably be next week before I can try your suggestions. I'll reply again when I get the results.

Evening.

Wouldn't hurt to power cycle router. Unplug, wait 10 secs, plug in.

Next I would do is forget the networks on both the Android and laptop and retry connection password.

I have a situation where Android would not stay connected to a router using WEP security. If you are using please change it to something more secure.

For laptop I would head to manufacture's web site and get their driver. Confirm driver number in device manager before and after install to confirm the change has taken. If it works for a while on laptop and stops check driver version again. If it has been updated you need to stop Windows driver updates.

Once you have drive installed please open up the properties of the adapter in Device Manager, click on the Power Management tab and remove the check mark on the line" Allow this computer to shut off device to save power" (words to that effect).

By chance you aren't using static IP's on either of these devices, that is address you set. Normally you want the router to hand out addresses.
