Input:
I bought a BEFSR81 and worked fine for about month and a half.
Then begun to experience connection drops 2-3 minutes, every day more frequently. One night it dropped connection 3 or four times within an hour and then WAN port stopped working. It was connected to a Cisco 575 VDSL provided by my ISP. Extensive check out with ISP tech support pointed to the BEFSR81 router.
I returned it to my supplier for tech support but couldn't make it work.
I bought a second BEFSR81 and guess what...never worked either!
Then I bougth a D-LINK DI-604 and a BEFSR41.
BEFSR41 had again a connection drop at the fourth day, I had to reset it.
D-LINK is been working solid, not even a glitch. Hope this be useful for Linksys buyers, since, for worst, Cisco -now the owner- said not to support Linksys gear.
I emailed LINKSYS support at  support.la@linksys.com
