that's new for me.
i rechecked my config and mine had multicast passthrough turned off as well.
does netflix use multicast? maybe to try turn that off as well?
i don't have netflix so i can't try. apologies
Disabling UPnP doesn't work. I just had another hang about 30 minutes ago that required a reboot. I was watching Netflix when this happened. The interesting thing is that Netflix kept working presumably because the router was still performing it's primary function of routing packets, but other services like DHCP, DNS, router logs, configuration website, etc. all stopped working. Because I couldn't connect to its website I had to pull the plug on it.
I am running the latest firmware 1.0.4.03. I will try resetting to factory defaults and reconfiguring without using the backup file. But, man, that is a lot of work and based on bcool's response I'm not convinced that'll work.

When you restored the old config file on the new firmware you corrupted it.
Only a reset to factory defaults and a reconfigure from scratch can fix it.
you might have missed the part where i said i tried it with an old config and when that didn't work, i reconfigured it.
but it didn't help the last time, so i'm not sure whats changed to help it now.
from what it seems, if not the upnp, there is something wierd with the firmware. its certainly not working very well in some operating environments.

Alright, I just did a factory reset and manually reentered my configuration. I currently have UPnP enabled. Things I'm watching for.
I'll report back with my findings. No news will probably be good news, but I will try report back within a week or two.

I got similar problem. I have to reboot my LRT224 once or twice a week to make it works.
Here is my network setup.
LRT224 connected to an Apple TimeCapsule in order to provide a WIFI network. I also have a camera connected to the TimeCapule via WIFI running 24hrs a day. besides I also connect my NAS to the LAN port of the LRT224.
About once or twice a week. I found that any device connect to the WIFI (Timecapsule) cannot access the Internet at all. However, at the same time, my Camera, which connected via WIFI of the Timecapsule, can be access from External Internet. The NAS is still conenct to Internet, can both download from Internet as well as access from outside world. Only devices connected to the WIFI are not able to retrieve anything from outside world.
Sometimes I can solve the issue by disable the port to my timeCapusle and resume it to make it works. Sometimes, I just need to reboot the LRT224 to solve the problem.
I suspect it is uPNP problem too. I got quite some rows in the log file saying upnpd UPNP rule is not FULL!!. Also another lines saying upnp Failure obtaining ip address of the interface eth1.
There are also some lines saying
upnpd AddPortMap... RemoteHost(null) port: UDP ExtPort 4500 Int: 18.104.22.168:4500 where the 22.214.171.124 is exactly my timeCapsule address.
It is quite disappointed that an over $200 router got hang every couple days. I updated it to the v1.0.4.03.

Thanks. Will give a try. But still is it an issue that everytime we have to reconfig by scratch everytime a new firmware is updated? Linksys should do a better job than this.

It lasted almost 2 days before a hang. This time everything stopped working. My wife said the internet stopped working and a few seconds later Netflix cutout. And again, the website was inaccessible so I had to pull the plug. After the LRT224 reboot everything was back to normal. As a reminder I did a factory reset and manually reentered the configuration 2 nights ago.
