Though I haven’t proven this theory out yet I’ve been wondering since it seems to me to be a difference in stability. So my neighbors all around me have U-verse and have had all kinds of issues in which a U-verse tech has had to come out to resolve their issues. I’ve had basically none, with a couple of exceptions (area-wide drops). One neighbor had to have the line at the curb completely dug up and reset, but that was a different issue. When they setup my connection, I asked up front to run twisted pair from the outside to my router/gateway instead of using coax. As I understand it, unless I’m mistaken, the default is to use coax which, sure enough, all my neighbors have. As it pertains to VDSL2+ (the protocol U-verse uses), is twisted pair more stable than coax as a medium for delivery? I’m just curious, because that would be an easy thing to ask for at the beginning. I don’t know that this is the case, but I would be interested to see stats on that. Here are my numbers using twisted pair after 113 days of data/error collection:
I’m not sure at what point, but some time over the past week or two, my 2Wire 3800 HGV-B router was upgraded to new firmware (by AT&T of course), version 6.1.9.24 or rather 6.1.9.23-enh.tm. I’m not positive this fixed it or if AT&T upgraded their firewall policy, but for whatever reason, my NAT loopback works now. This has been a major complaint by both tech-ey customers and AT&T tech’s on various forums I’ve read ever since U-Verse started it’s roll-out a couple of years ago. It’s a pain to work around if you’re doing any port-forwarding on the outside of the firewall and then attempt to access those open ports from the inside of the network outward. Well, if you get upgraded to the latest version or get the latest firewall rules from AT&T, you should be good now.
