Hi, I'm in a process of buying a new router and with my requirements (throughput > 20 Mbps, firewall and multicast) and I have been advised to get a WRT54GS with Sveasoft firmware. I have read some on the Sveasoft forums and have some questions: 1. I've read that multicast (IGMP v2?) has been added in later versions of the original Linksys firmware for the WRT54G. Is this the case for WRT54GS too? 2. If no, can this be enabled by Sveasoft as stated? 3. I was warned about stability issues when using Sveasoft. Is this the case? 4. If I use Sveasoft's firmware and things become too unstable, can I go back to the original firmware by resetting the router?
