Can ping but cant see LAN-device on WLAN-computer

Is the wlan zone trusted?

You will need to ensure that broadcast traffic is allowed between the LAN and WLAN or this won't work.

Thanks for answering.

aarontomosky: Its trusted. Do you mean Internet Properties - Trusted Sites, right?

diverseit: Thanks but this was what i allready had done. I will add screenshots from my Access Rules. As i said, the problem is that i cant add TV-Device to my Wireless PC.

craigbeck: Could you please explain where i can find this config?

If you are using simple L2 bridging and not captive bridging, broadcast traffic should be enabled.

Yes, I just wanted to make sure you set it up correctly.

You should check Access Rule #29 W0 Subnet and make sure it's the correct subnet or rather change it to Any.

I also wanted to you check your Window's firewall rules. Try disabling and retest.

If I'm not mistaken I believe Device Management works off of Network Discovery. Try adding the TV to the HOST file of the laptop.

Check the workgroup name of the laptop. If it's not the same it won't show up.

Still not working. Think i have tried everything by now.
The Laptop has former been part of a domain, but now in my home Workgroup. Could that be the issue maybe? Maybe something is locked somewhere in computer..  registry maybe?

Workgroups provide a basis for file and printer sharing, but they don't actually set up sharing for you. Did you try disabling the Windows Firewall via Services rather than the GUI (Control Panel)? Due to OS corruption there can be an disparity between the GUI and the firewall services still running.

Have you tried Homegroups rather than Workgroups? A Homegroup makes sharing easier.
Have you turned on Find Devices and Content? See here for details on setup: http://windows.microsoft.com/en-us/windows-8/find-pcs-devices-content-on-network

Do you have access to another laptop (friend or someone else) you could try to duplicate the issue?

Any update on this?

Nothing.. Tried almost everything.. Been kind of busy too, but will test with another Laptop soon. This case has been a real pain in the ass so far.

I mean the zones->configure wlan-> Allow Interface Trust

Wlan allow interface trust is enabled.
I tried with another laptop but still cant see tv. then connect to LAN and tv appears in device list.

I've always just done that and the zone trust seems to work.
the fallback is the old way with iphelper

Thanks but still not working. :( Why why why (crying out load)

Thanks folks!
I did a Firmware update and a clean setup. Easy. I now discovers my TV on WLAN.
The problem know is that i Cant discover my NAS. It works on LAN. I'll probably find a solution soon.. :)

Hi again!
Could someone help med map my NAS? I only maps when on LAN, not WLAN.
Its the reversed issue then last time.

I'd suggest opening a new Question to do so since this one is already closed.

I'll keep my eye open for it.
