Hi I have been having problems with my internet.. Spoke to m ISP Sky.. Tried different microfilters a new telephone been connected fine for a year, recently started disconnecting I have a crackerling sound on the old and new phone, old phone cant make calls but can only recive calls. The new phone can make and recieve calls still with crackerling sound. I have rebooted the router off and on for 5 miniutes. I can stay connected for a good 5-7 hours or whatever but at any random time I may disconnect and reconnect for about 30 seconds I have tested master socket and the test sockets in the BTline box I dont know what else to do and it seems my ISP is struggerling on what to do..
