Linksys / Cisco making bad produsts for years
This is really not new. When it comes to the residential routers from Linksys / Cisco this is part of many years bad decisions and sub par products. I have not purchased a Linksys router in years and even when I purchased the last one it was a WRT54GL that was running Tomato or DD-WRT, but never the stock Linksys firmware. I currently use a Netgear WNDR3800 and have been very happy with its performance and advance features.
As a side note the dismal performance and issues of the residential Linksys Cisco devices should not be confused with their enterprise routing and switching equipment which is and always has been regarded as the industry standard.
