1) How many Sats do you have?

2) Are they wired or wireless backhaul (connection to the router)?

3) What firmware version is installed on your Sats?

Sounds as though you had an auto-update from Netgear to get your system to V4.6.8.2_2.1.9. The auto-update process has been known to cause very unstable performance and can cause the type of issue you're seeing. Answer the above questions and the members on this forum can suggest troubleshooting/work arounds.
