Am I the last one using Thibor 15c for the WRT54GL? It's so easy to use as it is very similar to the Linksys default firmware, I am hesitant to switch! Anyone else? Reason for asking is, I noticed that with large LAN transfers (50-100 Gigs), after some extended period, transfer speed slows to a crawl. I wonder if this is the router choking? How do I tell if this is the case?
