Hello guys , I'm having an problem with connecting to the internet, right now only my modem is plugged in to jack point and it seems to work fine all day. my problem is when i use an adsl filter with the phone line , the connection dced a lot and it vary. it tends to work at night more often and definitely can't work during the day time. The modem i'm using is an dynalink RTA1320v6, my modem is new everything is new cables ect except my telephone line.This is how is connected ,the phone line is attache to an extension cable then to the adsl+2 filter along with the modem line then in the jack point. i tried a lot of isolation test on cables,everything should be fine because it's new. I was wondering is there such an modem that doesn't work with filtering or is it my telephone too old?
