Can this product do This : connect to a wifi network wirelessly (for example a caravan park that supplies wifi) then can i connect to the device,

Yes it can. I am presently using one to connect to a wireless network and then hook up to an ethernet only PC to give internet connectivity. Set it to WISP mode. One word of caution, the PC in my instance required to have DHCP enabled - which Windows 10 connection troubleshooter did for me. After that it works perfectly and allows said PC to also hook up to a couple of wireless printers. In this mode, as well as allowing an ethernet connection, it also creates its own wireless network separate from the main wireless network which any wireless device in range - phones, tablets, laptops - can see. Useful for a pub or restaurant wanting its customers on a separate wifi for the business.

Does this item work with public wifi networks that require browser based authentication?

There is a way round this but it does require you to be tech savvy.This can receive and repeat Wi-Fi signals.You need to write down the mac address of your tp link then turn it off.Use a piece of software on your laptop to change your laptops mac address to that of the tp link.Log into public/hotel Wi-Fi, do the login page etc.Turn Wi-Fi off then change your mac address back.Turn the tp link on and set it up to connect to the Wi-Fi. Set a different ssid for your sub network then as long as your tp link stays connected you can use multiple devices.This is how I use my chrome cast and tablet etc in hotels

will this product work with the Huawei E3256 Dongle?

Yes if plugged directly into the router but not if you use a USB extension cable. This is a pain as an E3231 will do. I think this has to do with the E3256 being dual-channel and needing more power than the MR3420 can provide over an extension cable.
