I have a feeling that my DSL provider is lying to me, but I cannot find a technical rebuttal online. Can someone tell me if the following makes sense:
I have ADSL which is supposedly "up to" 16,000 kbps down and "up to" 1024 kbps up. However, my speeds are maxing out at 5,800 kbps down and, unfortunately, 330 kbps up (speedtest.net). I am mostly concerned about the upload speed here. I am not torrenting or anything.
The internet provider claims that this is just because there are a lot of people in the building who are using the internet. I don't buy it, since it never goes above 1/3 of capacity. Plus I thought that cable was shared this way, but I didn't think dsl was. If I understand dsl it piggybacks on POTS, and since each subscriber has a dedicated phone line we should each get a dedicated DSL line to the isp.
I expect that internet is simply throttled at the isp level because they don't want to improve capacity, and isn't maxing out the local phone lines. I'm not a network engineer though, so I am asking: Am I right?
Also, if it matters, I am in Germany.
Try speedtest.net at 3a.m., then you will know whether your ISP is lying to you. – MariusMatutiae – 11 years ago
It entirely depends on how they wire it. It sounds the building is sharing a single line and provisioned from that. – Ramhound – 11 years ago
Check if your DSL router tells you what bandwidth it agreed to with it's counterpart. – TheUser1024 – 11 years ago
Cable is not shared this way — i have cable internet and speeds are as advertised – kinokijuf – 11 years ago
