Laptop hidden from smart TV

My home network consists of a desktop with Windows 7, connected by power line, a Samsung smart TV with an Ethernet connection and a laptop with Windows XP, connected by wireless. The desktop and the laptop can see each other, and the TV can see the desktop, but not the laptop.
My intention was to use the laptop exclusively to download and stream video to the TV, which at present is one of the desktop's tasks.
Any suggestions would be appreciated.

I can't see the full setup

But some routers hide things from wired to WiFi or vice versa. Samsung TVs fill the boards with network problems so you have too many probable causes. Including no support for XP.

Yes, that XP does upset folk but it's day has passed so you dig in and try as well as accept the passing of support.

Windows 7 has this Homegroup feature, XP does not. What if Samsung didn't do a plain network share support?

-> But right there you have your connect about WIRED AND WIRELESS. Your router model is absent so I can't check its manual. That can be tested by wiring the XP machine. If it shows up, it's a router setting.

Parting advice. WIRE THAT XP MACHINE. WiFi is slower.

Re: laptop

- What app(s) on the TV don't see Windows XP while they do see Windows 7?
- What version of Windows XP (Home, Pro, Media Center), what service pack?
- Did you consider to use the TV as monitor only, connected to the laptop via hdmi?
