My current ISP is Northland Cable. A lot of people are not to familiar with them. The Netgear seems to be running pretty good, but I was not sure what I should look for or how to test it to see if it is working good with the XR500. It seems like my connection is always stable and I always have an A, A, A rating at DSL reports with anti-buffer bloat turned on. Just wasn't sure why this modem was put in the bad list since it does not have the crappy Intel Puma chipset in it.
