said by mjn426: for the landline coming from the pole.
when was your drop replaced coming from the pole, more than likely you will need a new drop if its pretty old, just depends if its outdated or not.
As far as coax or not, prefer cat5 to everything, less likely to need future repairs. very few truck rolls on houses that are all cat5 vs coax just because of fittings, sometimes the chipset that sends the signal out of the modem on coax goes out.
Hope this helps
