I nodded. In the CNET Networking forum the issues with WEP are legendary with folk bewildered by how other machines work fine except this or that one.
The short answer is to move to WPA today. I have limited time today so I can't type in the long reasons why this matters as well as not hiding the SSID or how important it is not to use MAC filters.
Apologies if this has been covered but multiple searches on the forum have not produced and close matches to the following issue:
I recently purchased the Samsung LED 3D TV, model UN55C8000XF along with the Samsung Wireless Adapter, model WIS09ABGNX. I also have a Cisco/Linksys wireless router, model WRT54g with the latest firmware that is available on it. I can get the TV with the wireless adapter to connect to the wireless router just fine. The network test passes just fine. The problem is after the TV is powered off and then on again it keeps saying "wireless network detected - do you want to switch from wired to wireless?". I indicate "Yes" and it eventually connects to the wireless router and everything appears to be ok. Then with the TV still on (never powered off since switching from wired to wireless) it asks the same question again in a minute or two. I indicate "yes" again, it eventually connects and all is fine...for another couple of minutes when it keeps asking over and over again.
No other devices, (PC's, iTouch), have this problem with the wireless connection dropping. I also purchased a USB 2.0 extension cable thinking that possibly the signal was being blocked by the TV itself but that didn't help and the TV is literally 20 feet from the wireless router.
Any ideas? By the way WEP is enabled and the SSID does not have any spaces in the SSID name. Again, it connects and "talks" to the internet but seems to be constantly re-prompting me for switching from wired to wireless.
