(I'm on a Mac, BTW.)

I have a Linksys WRT54G2 that has been serving as our Wi-Fi hub for some time. We love it.

Today I bought a Blu-ray players with Internet capabilities (streaming NetFlix), and plugged its Ethernet port straight into the back of the WRT54G2.

It seems I can't use both at the same time.

As soon as I start using the Blu-ray player, the Wi-Fi connection is immediately dropped on all other connected devices and the SSID is no longer visible.

I'm not sure which fixed it, but I changed the broadcast channel from 6 to 11, and plugged the ethernet cable into a different port on the router (it had been in port #1, now it's in #4)

Now it's all working fine.

If your ISP provided the router then possibly some ports are hardcoded for special uses in the firmware (using firmware modifications done by the ISP). My router also has 4 ports but only 2 are usable because the ISP has reserved the rest for IPTV. You may have been tryin to use a port that's reserved without your knowing, which would explain why using another port fixed it. – Torben Gundtofte-Bruun Nov 27 '10 at 13:40
Sounds like your blu-ray player is emitting radio signals that mess up channel 6. That's common with devices like microwaves, but suggests a manufacturing defect in a disc player. If you hadn't already worked around the problem, I would have suggested asking for a warrantee replacement on the player. – Isaac Rabinovitch Sep 4 '12 at 1:07
