After much wailing and gnashing of teeth, we isolated the source of a bug that plagued us for months. Our venerable Linksys BEFSR41 router developed a pesky connection drop problem, amongst other intermittent bugs that required a power down reset. So we assumed that the old girl was dying and bought a new one.
Wrong move.
Same bugs. Updated firmware. Same bugs.
Emailed Linksys. No answer.
Contacted ISP. Tech came out and checked the lines. Nothing out of spec.
Tried a third Linksys. Same bugs. Updated firmware. Same bugs.
Tried D-Link EBR-2310 router.
Huzzah. Works. ZERO BUGS.
Conclusion: Cisco Systems (new owner of Linksys) may be in for a drop in sales, if this is an indication of their "Quality Control" and customer service.
