Driverless Wireless mouse (& keyboard) for a distance of 8m

I have a video player connected to the TV : alas  when short videos (of a few minutes)
finish, I often have to walk about 8m (from my dining table) to use the mouse (&
keyboard) to click to go to next video.

I've tried a few wireless mice : Logitech Darkfield Anywhere, an unbranded wireless
mouse & an Imation wireless mouse : all of them only works within 1m distance.

So far all the above mice don't require any driver : just plug their USB dongle to
the video player & it just works on-the-fly

Anyone know of any long-distance mice (& keyboard which I use less frequent
but still good to have)?

A 2-in-1 ie a USB dongle that controls both mouse+keyboard is fine too.
 eBay or Amazon online links that ship to Singapore will be appreciated

Ideally if the wireless signal can go thru a chair that's in between or
a person sitting in between, it will be good

MK270R exists in Amazon: just found it but it costs a lot more.

Ok, found MK520 & MK320 : both long range but which one has a
longer range?  Contemplating between the two.

Well 3 of my wireless mouse won't work beyond 2m;
perhaps these are old mice.

Ok, MK520 is just as long range as MK320 & supposedly better
value for money at Amazon's current offers:

A couple of local stores finally listed they have MK520 but at
50-80% higher price than Amazon (as I'm getting free shipping
internationally for the total qty purchased):

Next is Logitech's warranty international?

>USB extension cable
Well I did move the various mice within a 5m perimeter around the room
while aiming at the USB dongle that's stuck onto the video player & no luck
too (ie can't move the cursor).  So I think it's not the positioning/angle of the
USB dongle with respect to the mice but rather the signal strength is too
weak for that distance.

Or is there any way I can test using a Wifi signal "amplifier" (ie something
to strengthen the signal so that the signal could go the extra distance?
You didn't mention if the USB dongle is in the front (so most likely line of sight) or in the back. If it's in the back with no line of sight, try the USB extension cable to bring it into a line of sight situation. Even if it wasn't the case, moving the USB dongle away from the original location (even if it was line of sight) with a USB extension cable can still help if there's radio frequency interference at that spot.

There's no radio frequency enhancer device available (Wi-Fi extenders work very differently).
