Steam Link help

[Triventular]

so i have a problem where i have steam link on my phone connected by wifi and i want to stream some games on it from my pc (connected by lan). but when its connected to lan, steam link on my phone can not detect my pc but when i use a cheap usb wifi dongle it then detects it. its strange because i had it stream games from my pc with lan before. what am i doing wrong?

Some routers have a security-(mis)feature where they don't allow WiFi-devices to communicate with Ethernet-devices. You need to check if your phone can ping your PC and vice versa first, and if they can't, then you should look at your router's settings to see if you can disable the aforementioned (mis)feature.

what would that feature be named? i dont exactly know much about routers

No idea, every manufacturer hides the setting in different places and under different names.

You need to make sure your phone can ping your PC.  Also make sure your phone is connected on the same subnet as your PC.

 

For example, if your PC resides on 192.168.0.x then your phone should also reside on 192.168.0.x subnet.

i tried and it cannot be pinged with ethernet but it can be pinged with the cheap wireless adapter i have. I don't want to use the adapter though because its only 2.4ghz and its really slow. the internal ip addresses of my pc and android both have 192.168.1.x format

The feature should be AP isolation or something to that degree. Its a security feature to make sure WiFi devices dont have access to your home network, effectively only giving internet on WiFi. Its for when you have company over and they need WiFi, you dont want them digging in to your network. Id look in your WiFi settings for this feature, hopefully you will find it.

I think we are getting ahead of ourselves here, the first place to check would be the Windows Firewall as your wired connection may be set to public instead of private which would block Steam Link traffic.  Although its pretty odd that the USB WiFi isn't also, but you may have perhaps assigned it to Private when you first plugged it in?

thanks i'll try to look for it

 

edit:

i found it and its hidden lol like i have to do some html work to make it appear but when i try to disable it, it enables itself again. i think its outright disabled by my service provider.

i've set everything in my house to be on private not public and i've also tried disabling my firewall which still didn't do anything.

Well that's stupid, I wonder if it was disabled before and they enabled it in a firmware update, thus why it suddenly stopped working?

Might be worth calling your service provider to let them know its a problem as that's a pretty huge restriction to put on a residential router.  If its only affecting 5Ghz then it would seem in fact its a bug, as surely it should affect them both the same?!

In the meantime the only real solution would be to get a second router / WiFi Access Point and use that instead for the WiFi.  If you do just remember to disable DHCP on the second router and plug it into the main router via a LAN port not the WAN.

well i think it was working before because we were using a different router. our service provider "upgraded" our router and when i wanted to stream to my tv, it no longer worked. its just stupid. a lot of people with the same router but different service provider also had the same problem. I saw this thanks to a very long github page about this issue.

This is why I always recommend bridging all ISP provided potatoes modem router combo units and using your own router, preferably one capable of running custom firmware such as OpenWRT, DD-WRT, or a variant of Tomato, such as AdvancedTomato. This way you have full control over your network to make it operate the way you need it too, although be warned that going this route leaves you with zero support from your ISP and does require a lot of willingness to learn and troubleshoot your network.

I went from DD-WRT to OpenWRT all the way to pfSense now.

 

Once you realise what a good router can do and the difference it makes to your broadband performance and reliability, you can't go back to potatoes.

I will never forget the first time on 5Mbit I streamed the Microsoft E3 conference in 1080p while running a huge download, but thanks to DD-WRT and QoS it throttled the download right back so the stream worked flawlessly.  I ended up on pfSense because once I had 100Mbit (sadly now only 67Mbit) consumer routers just couldn't handle that load any more and the custom build of OpenWRT I had been using was no longer being supported.

 

Perhaps the most useful thing I did when going to pfSense was install pfBlockerNG and region locked my port forwards to the server, so it only forwards connections from countries I am ever likely to visit.  That one step has blocked ALL password crack attempts on my server!

 

Recently I added a common attackers and a CoinMiner blocklist.  No more CPU cranking up to 100% on random websites, and no need to trust browser extensions to do that for me (as you literally have to hand over permission for them to snoop on what you are doing).
