To prevent the switch from interfering with your DSL. >Secondly, my telephone wiring is more than 15 yrs now (2007) and I

any problems from your home phone wiring and eliminates the need for
micro-filters on all phone outlets (but not RFI filters on dimmers). -- Best regards, John Navas <http:/navasgroup.com>

Hi How about changing the ADSL2+ Modem to DLink or Linksys ADSL2+ Modems? I currently using Speedtouch 536v6 given by my ISP. Would it solve the DSL Problem without changing the dimmer switch? Next, I also realise that street lamps affect DSL Sync? I am staying at an high-rise apartment. Does street lamps affect DSL Sync no matter how high you live in an apartment? Leewy | |||||||||||||
