I've been struggling with very slow DSL Internet service for two weeks, and I've had the AT&T technician out twice. Every once in a while, my service is normal, but usually it's too sluggish for anything but text. The AT&T tech checked connections in the switching center, and everything seemed normal. She decided there must be something wrong with my home telephone wiring, and suggested I rewire the phones with Cat-5 wire. I plan to do that tomorrow, replacing a 100-foot phone line run with Cat-5.
But should this be happening? I've had good DSL service for 2 years, except that my AT&T 2-Wire modem went out after 18 months and had to be replaced with a Netgear modem.
Any suggestions or techniques or cautions for Cat-5 wiring?
