Changed filter, tried different tests and all indicated modem.
Managed to get good price on telecom modem, even though i've seen posted here better modems to get.
Had going for 2 hours, no problems so far.
What did surprise me, is i'm now getting faster international speeds, local about the same. Also web pages loading faster. Ping international is quicker to, on linksys Los Angeles was 700 milli seconds, where as telecoms one 36 milliseconds.
Speed on linksys 5 Mbps, telecom one 10 Mbps Los Angeles. Looks like more wrong with linksys then just losing dsl, so far real glad I changed modems. Both did just over 10 Mbs for national data.
The linksys was about 3 years old.
Edit: looked up speedtest data, on speedtest and saw ping 36 on telecom modem
