The DSL light on my BSNL wifi modem becomes unstable during night time especially after 7:00pm and gets stable for only like 5-10 minutes and then again starts blinking.I'm a gamer so the frequent disconnections at night don't allow me to play online.I don't face such problems during day time.The plan I'm using is BBG ULD 1425 PLUS COMBOAlso as per this plan I should get a speed of 4MBPS but while testing with BSNL speed tester it usually shows a speed of 2.5-2.7MBPSAny help would be appreciated thanks
