I’ve been experiencing problems with my phone line and DSL connection for quite a few months now. However, the problem was always intermittent. I would experience static on my phone line and DSL loss of signal errors at random, non-reproducible intervals. I just couldn’t figure out what was going on. So, I finally called AT&T and asked them to check it out.
They sent a service technician and, as I expected, the line was clean while he was here. However, 2-3 hours later, the phone line started acting up again and the 2Wire HomePortal was bathed in red lights again. Oh well, that repair didn’t work.
A few days later, AT&T calls back to ask how they did. I told them that the technician could not fix the problem because the line was clean when he showed up. And, I didn’t give it much thought after that. But, lo and behold, a few days later, someone from AT&T calls me back and asks if they can send another technician out to troubleshoot my connection. Well, this second guy fixed the problem.Almost a week has passed and the DSL connection has been rock solid. No static on the phone line either.
So, the technician tells me that I shouldn’t have the data line routed to all my phone jacks. Said that was fine for older houses with a limited number of jacks. However, for newer houses with 8-10 jacks, wiring the data to all phone jacks will weaken the data signal and cause interference. I don’t know if his explanation was technically right or not, but his fix of converting one phone jack to become a dedicated data line sure worked.
