Hi @Chardcaringal,

FYI the fuctionality you're looking for is called a "captive portal."  FYI, this is the business wireless forum, and the TL-WR940N is a consumer/home product.

Here's some more info

Manual for the TL-WR940N

I think the answer to your question is no.  But it looks like some home routers may.

You might try posting your question on the consumer router forum and/or redit.  Also contact TP-Link customer service.
