I have been watching various shows on netflix via the web for over a year. Until recently, never had a problem. However, about a month ago, it got very laggy (stopping and buffering every two minutes, or more often...) especially in the evening. Cold reboot does not help. Is this because web activity goes up in the eve (east coast time)? Other things seem OK with PC. Any suggestions to get better viewing (reduce elim lag). Use Firefox - updated. Thx...
