I've had mine for ~9 months and while it originally worked like
a champ, eventually it started to "get stuck" every so often.
Pinging the router itself returned "Request timed out". This
would happen at various times, sometimes once a week, sometimes
twice a day ... no rhyme or reason.
I upgraded the firmware, and it got rid of the bugs for like, a
month, then they came back. The latest conversation with the
LinkSys tech folks was to uninstall my Anti-Virus software, which
seemed a bit drastic. I haven't, but the router hasn't crashed
since the last power-cycle, which was probably 10 days ago.
Right now I'm keeping a sharp eye on it, and if it goes south
again, I'm requesting an RMA # for a replacement ... I think
that's good for a year.
