Ok, so I have my lovely Netgear XR500 with GeoFilter and have recently upgraded the firmware from 184.108.40.206 to 220.127.116.11
After a few weeks of going nuts, and tweaking the GeoFilter + QoS, I could not work out why I was not doing well on BO3 (Xbox 1) .
Then having a look at the Netgear Community, I noticed a thread between a user and NutDuma and they have confirmed back in September, that indeed a bug exist with Firmware release 18.104.22.168 that is causing slow speeds and Xbox would be taken offline if GeoFilter was enabled and poor matchmaking etc.
So just loaded Firmware 22.214.171.124 and so far, gaming (console) is so much better ;0)
Netgear for there XR500 have just released the XR500 Firmware Version 126.96.36.199
