[speed/latency] Two DSL Lines, one is good and one is bad
Hi, our company have 3 phone lines and 2 separate DSL. There is a static ip 7Mbps plan (called verizon to lower to 3M cap), which is the one having slow speed and disconnections issue, and another dynamic dsl line that never have any problem.
This two weeks our static ip line been having average 400-700 ping and about 0.5 - 1Mpbs download speed. And for months we are getting disconnections that is fixed with a modem restart. Some times we get 3-6 disconnections a day. While the other line is having about 30-40 ping and 4Mpbs download and never have any issue at all.
We have called verizon over 20 times and have 2 techs came to our location, but all they said is you are too far away and the line is bad and there is nothing they can do. And they suggest we call and lower our speed to 3Mbps, which did not solve the problem at all. And we changed two Modems already. We are having this issue for months.
My question is why is the other dynamic line doesn't have any issue at all? Don't they both go thru the same phone line to the DSL hub?
More info: The Static Line is our company's main line with about 5 devices connected to it, and we can not use the other good dynamic line because it is for a reseller that works in our location. And he is the only person that uses his own dynamic line. And the dynamic line was installed about 1 year after the Static Line.
Here is the stats from the static ip line.

Thanks for any help as this is affecting our business greatly

the stats on that line look rather good (at that speed anyway). i would say 7 is pushing it to it's breaking point, and maybe a little further, but 5 should be plenty doable with those stats.
when you are upgrading your speed, do it incrementally, and try to maintain margins of at least 12 or so if possible.
if you keep margins of at least 12 (and it isn't going all over the place), then the issue isn't the line, but rather congestion. if your margins are going all over the place while the speed is the same, then your line has an issue that downgrading speed won't help.

Sorry, but I don't really understand the margin that you are talking about. Verizon already placed 3Mbps cap on our 7Mbps line and we are still getting 600+ ping and 0.5Mbps down. (While our other dsl line is getting 4-5Mbps)
Because the slow speed is affecting our daily functions at work, we just sign up for a 4G internet. And the speed is great (4 - 10Mbps) and it is much cheaper than verizon.

margin is basically how much tolerance your line has for noise, the higher the number, the better, meaning your line can tolerate more noise, and is cleaner. this margin drops as you add more speed.
for the fact that your line looks good, i'd say it's a congestion issue somewhere.
i'm glad you found a good solution to your problem by switching to 4g service

They two lines could be on different cable pairs between you and the Central Office where the DSL gear is located.
While the cables may run more or less the same way, one could be taking a slightly longer route (increasing your distance and thus lowering the maximum speed you can sync at) or be more susceptible to noise and other conditions that would impact your service.
