Easier way to do LAN play (AD-HOC)

[Rivalartur513]

If possible could there be easier way to do LAN play with other decks without the use of a hotspot. Such as AD HOC.

for real LAN gaming without any of the devices linking the adhoc network to the internet you might need to leverage offline mode (enabled before disconnecting from the normal internet) or using this 3rd-party free and opensoyrce replacement to steam APIs:

there might also be a way to configure one device as a gateway to the internet, but network configuration is eldritch magic of the worst kind... someone is probably going to die trying, and even being successful might cost your sanity

If you have two USB-C ethernet adapters and an ethernet cable, it should already just magically work. Plug them in to each other and they are guaranteed to get IPv6 addresses that can reach each other. They'll probably get valid IPv4 addresses, too, but I haven't tested that.

Of course, you'll also need to be playing games that actually support LAN play, and not a lot of games support that nowadays. You may also need to look up your IP addresses and manually exchange them if the game's can't do any sort of multicast discovery.

Actually, yes. Ad-hoc WLAN is a thing, it can even be set up on Linux but not exactly in a user-friendly manner.
All we need is a GUI page for the existing functionality. I say "all" well-knowing that there's a lot of devis in a lot of details, but I'd really like to see this happen.

Furthermore I think a steam app/steam link hdmi dongle needs an adhoc feature where it streams directly from the deck to the app/device. That way I can just connect a controller for player 2 but just cast it from deck directly to fix latency without having to plug things in on my deck and leaving the benefit of handheld mode and it’s controls.

I would like a new steam cast device or an app that could do it to a phone with a dogbone.

Google Chromecast 4 runs Android TV and can successfully install and run the Steam Link android app, which uses any valid local network to stream Steam (or actually anything on the host computer screen as long as Steam is running)

It can also pair up bluetooth controllers like DualSense (PS5) and DualShock 4 (PS4)

You can then use those as an input device on the Steam Link app while the Chromecast gladly outputs the game via HDMI to whatever screen it's attached to

ps: I used to do the same thing with an Amazon Fire TV 4K stick but it was harder to get things going (sideloading the app, spotty controller pairing, comparably bad performance, etc)... other recent android sticks like Xiaomi's probably work fine too, qnd other devices like Raspberry Pis running Raspbian can also use a Linux version of the Steam Link app... heck even a Deck can use Steam Link to act as guest on a local network to another Deck acting as Steam host

Would love to see this implemented, I could play games with my brother on long car rides, would be a welcoming feature!

While I like the thought I don't think this is a worthwhile feature to develop.

Imho the overwhelming time a deck has internet it is via wifi. Any other decks are much better of joining that same wifi. One device joining two wifi networks is nasty businesses at best.

If not via wifi they mostly don't have internet at all. Which means the overwhelming majority of games won't work in multiplayer. While multiplayer without internet was a thing most publishers abandoned it decades ago. Digital Restrictions Management and all that. Plus the power to turn off the servers to encourage the players to move to the next release. Whats not to like. But yeah, a few games at least should work.

Lastly there is internet via cable. It should be easy to share from a networking perspective but then some will be stuck with that unwieldy cable in their deck. Much better to just plug it into a real AP and join all decks to that instead.

So basically its only small niches that would benefit. Probably too small for Valve to bother. And I don't see independent devs buying additional decks just to tinker with this either.

I will buy 3 more decks if this becomes an easily utilized feature. I'd love to play locally at work on my breaks with friends. And at home with my adult children.

Exactly. I wish this feature existed so my kids could network and play while in road trips. Bringing a router along and keeping it powered just for this purpose is a pain in the ass.

This would be a great feature for the Steam Deck and while yes it would work only for games that have offline LAN multiplayer it would still be good for playing the games that support on the go where there might not be easy access to Wifi.

While the feature is technically possible with tinkering right now in its current state it's not very user friendly. However if the valve were to implement it officially with support through a UI in the main settings in Big picture mode this wouldn't be as much of an issue.
They could have it simply be configured to use ad hoc automatically if no Wi-Fi network is detected, and if a Wi-Fi network is detected switch to that instead.

+1 for this feature I really hope they bring it to the Deck in a future OS update.

I really hope they'll add native ad-hoc support for the steam deck, or rather steam in general, as I play a lot of lan capable games with family.

Would probably need to be a SteamOS thing, could be configured on others that have Ad-hoc support in the chipset, needs more than just the Steam client to make it work, never know though.

This would be awesome. Being able to create Wireless LAN parties without the need for a wireless router.

Agreed, it would be awesome. And depending how they do it could be even more beneficial to PC gamers beyond just the Steam Deck.
