I have a Rev C1 with the latest firmware. When I turn wireless on, my Linksys NSLU2 file server goes down after a short time. When I turn wireless off, the server will come back up after a time. This is very repeatable. I tried to separate the router from the server ( ~ 25 feet) and use different modes (N, G, mixed) to no avail. I have two other wireless routers (G/B ) that work in the network without problem. I now also notice that my Dlink DCM-202 Cable Modem will go down frequently. Power cycling will fix it for a bit. My Dlink DNS-323 file server also went down requiring a power cycle. The only solution I found was to turn off the 615 wireless radio !! The reason I bought the router was just to use the N radio capabilities.
Has anyone else experienced this ?
