Certainly !recovery

Monday evening I was getting annoyed by stuff downloading slowly on my Nexus 7 at my Berlin flat. What first seemed to be just a bandwidth issue took a totally different turn …

Initially I thought: “Okay, time to move the mobile devices from 192.168.178.0/24, the Alice ADSL link, to 192.168.176.1/24, the congster VDSL link — need to tackle that anyway to cancel Alice …” Few did I know at that time …

Someone killed my VDSL performance and the VDSL Modem :(

Relocating to my stationary laptop in my Berlin flat, first I checked what the ADSL line was chewing on — only to witness that it for hours was suffering from repeated link loss, according to the log. Which, to put it in relation, were only going back to 20:something around 23:something when I started to look what’s going on. (Usually, they contain at least one whole day.)

Okay, no deal, wanted to make the congstar-VDSL link primary anyhow, so … WHAT THE FIRETRUCK?! It was then that I found out that the VDSL link died around 4 a.m. that day, and, checking the FritzBox 7570 that was serving that link, I saw that it did get information about the DSLAM but was unable to synchronize on the link anymore. Well, okay, VDSL died, so what — just call the ISP and file a ticket … Which is not the way the no-frills company of Deutsche Telekom works. There you can only chat with people, from 9 am to 9 pm. Outside that window — get your dose of IP elsewhere, and be sure to set the alarm clock …

SNR graph shows that something bad was done ...

Annoyed beyond belief, I looked more deeply into things. Well, the VDSL modem seemed to be fused completely; the ADSL modem on my (temporary) other line seemed to be brainwashed as well, as it can’t keep the link up anymore. What the hell happened here? After focusing on getting a stable online connection — by bringing the fall-back 3G connection via FONIC/o2 up –, I looked at my options. Unfortunately I started the 3G link at 23:something, so a full day of 2,50 EUR was taken off the balance. Running into the next day, and doing some reboots of the FritzBox, and therefor causing reconnections on the 3G side, trying to get the 7270 into a working state again, well … obviously FONIC took another 2,50 EUR from my balance — which, as I found out a day later, wasn’t backed by money on my account. So, the link did connect after midnight but no data was flowing — I’m not sure that that’s a proper, even legal, business setup, but I have other things to address first. So, stuck without IP over two DSL links and a 3G backup, I had to reconsider my options again …

Connectivity restored (7360)

I briefly tried the 7570 on the ADSL link and it did connect, so I knew a) that the ADSL line as at that time was working and b) “only” the VDSL part of the 7570 is fused. Since I bought a new 7360 off congstar, cheaper for new customers and actually a lot cheaper than on the free market, I brought that in place: changed IP, connected to VDSL — and it at least synced with 51/6. Fortunately the 7360 is running Fritz!OS 5 already — something AVM still does not allow on the their former flagship 7570 — so I could import the settings from the 7570 onto the 7360 and save some time searching for congstar credentials. The 7270v2 was already running a beta of Fritz!OS 5, so importing its data onto a 7270v3 was rather easy.

Connectivity restored (7270v3)


 
The catch here is that now, after bringing new gear in position, I have a severly limited performance — and two fused devices I want the one how is responsible to pay for.

First of all, I’m now down to a meager 6 MBit/sec uplink which 4 days ago was at 18 (limited by the tariff that “only” allows 10 MBit/sec upstream) — this is basically unacceptable. I want to know what happened in the five minutes after Sat 05 Jan 2013 09:35:02 AM CET, as after that my VDSL link was crippled from 82/18 MBit/sec capacity to 81/4 Mbit/sec down/up:

Secondly, as my VDSL modem died, I want to know what was done around Mon 07 Jan 2013 04:25:23 AM CET; it’s a bit early for T-Com people to work, but that’s around the time by VDSL-modem finally died:

While I don’t say, as of now, someone did this on purpose, I’m faced with about 200 EUR in damages, I’m focussed to find out what was done, either in my apartment house or on the Telekom side; starting around that time, even the ADSL line started to become erratic:

I’m afraid this is terra incognita, but anyone reading this, please speak up on ideas how to make a legal case out of this.

Essentially, I’d sue congstar for the fused 7570 and Alice (now o2) for the errtic 7270, as they are the people I have contracts with; objections?
