Samsung LE40B657 TV DLNA Problems

by naderiano / January 21, 2010 3:19 AM PST

I have connected my TV (6series 40" LCD) to my ADSL wireless router (Cisco EPC2425) via ethernet cable. When I connect my laptop wired to the same router I can enjoy DLNA on my TV and browse media. But when I try to connect wireless to the router... no luck. Any idea?

I have tried some things:
enabling, disabling my networks
reseting modem
changing wireless channel
chaning MTU settings from 1500 to 1350
disabling master brower and re-enabling it
turning off windows firewall
removing spyware doc and NOD32
using different IP addresses
changed workgroups
disabled ipv6

I can ping the TV with wireless but it doesn't show in samsungs software... I have windows 7 and windows vista on 3 computers... it's the same on all.

when I view computer maps in networking and sharing center as soon as I plug in the ethernet cable the TV pops up... as fast as I disconnect it goes (wireless on).

can anybody please help me? I will give additional information immediatly if required.

best regards,

Are you using the WIS09ABGN LinkStick dongle, or are you using a generic wireless USB device?

Thanks for the quick reply!

I have connected the TV using ethernet cable.

Have connected my computers using generic (normal) wireless adaptors (Dlinks on all computers)

As soon as I plugin the ethernet cable the TV pops on on my computers, as soon as I plug it out... it's gone!????

In the TV manual it says my computer could be connected by wire or wireless! What could be the cause?!?! I have worked on this for three whole days with no luck,,, please help!

Wireless DLNA

The TV broadcasts (multicasts) discovery packets for the DLNA service. If your PCs can't see these, they won't see the TV as a DLNA media player (and the TV won't see their media servers as sources).

Some routers don't pass these broadcast packets to the wireless part of their network. That could be the problem here. Check your configuration to see if it can be enabled.

I found the problem.

It was my ADSL Router (CISCO EPC2425 I got from my service provider COMHEM here in sweden)which didn't allow the wireless/wired multicasts even though it was enabled on my modem.

I connected another wireless router (netgear wgr614 v9) which I had to it and now its all good. Wireless DLNA I have.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
