don't know if this is useful information ... ...
i recently moved my computer further away from the phone outlet .
i just bought a longer - 50 feet - phone cord and re-connected it .
i could hardly get any throughput . phoned the server who told me that ordinary phonewire extension does NOT work at 50 feet .
so i bought and installed a 50 feet CAT6 NETWORKING CABLE and my problems are over .
anyone need a 50 feet phone extension cable
