I have a Belkin Pre-N network at my house and liked the specs on the new Linksys product (WMP300N PCI adapter and the WRVS4400n router and access point) for my office. Out of the box nothing worked. An upgrade to .13 firmware in the router at least got it working. Speeds are impressive, but as many others have noted, the system hangs up at random times driving users to distraction. I returned the product and reinstalled my Cat 6 cables.Once Linksys gets the bugs out I'll try them again, but they released this product without enough testing, in my opinion. This is a classic example of buyer beware.
