Mysterious internet/ethernet issue (kinda needtesting/connection/communication service to diagnose it ???)
Why do these subnets even exists ?
Why can't the internet function with one gigant routing table ? Tech don't exist for it ? No automatic join/leave/acquire ip address/etc. Subnets are needed cause routers are stupid and can't figure out where traffic should go ? Routing table must be constructed manually with manually created subnets ? Weird bro. Bye, Skybuck |

Mysterious internet/ethernet issue (kinda needtesting/connection/communication service to diagnose it ???)
Ok I called ziggo a couple of times to try and get to the bottom of this.
At least the television section of ziggo was usefull, they will send a network engineer to try and diagnose the problem when it comes to noisy signal. The internet section/service/support of ziggo was a bit less helpfull, but they try. Questions asked by me: 1. Is a custom modem allowed, can I buy a custom mode: Answer: no not allowed, it is "allowed" to have old cable modem 2. Is a screenshot from their settings on their end possible to be send to me ? Answer: no not allowed. 3. Are they willing to perform some tests with me, with my own software, to test if the cable modem and internet is working properly, port-wise and such. Answer: I'll ask, and eventually no not allowed, to much risk to their systems. I did suggest installing a virtual machine, they girl on the phone thought that was neat. Later I guess a superior/supervisor guy came on the phone claiming to be a programmer himself, futher questions asked to these people and girls and such: 4. Does ziggo have a testing facility where they test all of their combinations and such ? Girl wasn't entirely sure, but yes such a division exists but nameless or she didn't know. 5. Later I asked the guy do they test combinations of new gear with old gear. |

Performed network scan of a certain range did find some ips but probably not my modem. I am now pretty sure the cable modem is located on 192.168.1.1. I can ping it, but when attempting http://192.168.1.1 It says connection was reset. Perhaps I configured the modem in such a way that only a certain source IP is accepted, but I already did a factor reset. Maybe have to reset it a couple of times, but I don't think that is going to work. Any ideas ? Ever seen a modem say: "connection was reset" ??? MAC filtering? The 15-second factory reset should clear that setting, though. |

Mysterious internet/ethernet issue (kinda needtesting/connection/communication service to diagnose it ???)
Today I performed some more tests, from wi-fi hotspot to somewhere else/cable modem.
From these test I learned that windows security center and windows firewall must be running (with that the services I mean) If windows firewall is off (with this I mean the windows firewall is stopped) then inbound connections udp and tcp apperently don't work. Why this is I will have too look into, perhaps this is some windows security feature or architectural thing. So far everything is working as normal, which is good news. (At least when marvel adapter is used). (Also better test programs where used (reminder for myself both 2.97) ) Bye, Skybuck. |

Ziggo network engineer has replaced tv cable, noise is now gone.
Shaky image on one tv channel remains but this is a problem somewhere else. Have not yet tested getting into cable modem or testing speed. Speed is something like 90 Megabits down, 10 Megabits up or something. But I take this with a grain of salt, might be a bit higher than previously though Bye, Skybuck. |

Oh it was 20 megabits up, and ping time 24 ms.

Oh I forgot to mention... he didn't just replace tv cable...
He also replaced the wall socket... with something new. The one in there was very old. He also shortened the green cable a little bit and re-attached it. He had a nice trick though: Instead of connecting the coax to the splitter. He connected to coax directly to the tv. This also got rid of the noise ! which amazed me ! Exact problem remains unknown to some degree... we talked too much about other computer tech. Didn't get to talking about him about cable modem menu issue... Not sure if he could have helped probably not... but could have tried. Maybe his excited chat about tech was a diversion tactic... not sure It was a bit frustrating... but also kinda enjoyable... but this guy went off like a rocket... finally somebody to talk with about tech. This guy knew almost everything there was about tech. The only things he didn't know what how SMT/symetric multi threading worked on AMD ryzen... and L1 caches. So I explained this too him and also showed him AIDA64 benchmark results and such... Pretty cool chat =D Bye, Skybuck. |
