Hey everyone! Did my best to try and solve this on my own through searching posts on here. Got myself to a point where I’m not sure what to do and thought I could ask for help.
I am renting a detached house in Tsukuba, Ibaraki. Currently the owner has a contract with NTT docomo. With the GE-ONU, he left his Elecom WRC-1167GST2 ([https://www.elecom.co.jp/products/WRC-1167GST2.html](https://www.elecom.co.jp/products/WRC-1167GST2.html)) and that’s the current setup.
Using [https://v6test.ocn.ne.jp/](https://v6test.ocn.ne.jp/), I am currently connected IPv4 over IPv6 through OCN Virtual Network.
[https://inonius.net/results/?userId=187bdbb418d9](https://inonius.net/results/?userId=187bdbb418d9) taken at around 10:30pm.
Right now at peak times at night, I am getting around 2-3 mbps download, and 200 mpbs upload. I feel like something is more wrong than just congestion, because seeing other posts and [minsoku.net](https://minsoku.net), it feels like at night people don’t drop down lower then 10, especially those with IPv4 over IPv6 connections.
During the day we get 200-300 mpbs download and upload speeds.
Reading online I get the impression that IPoE should solve the congestion issue, but I’m also reading that 8 providers are using the OCN virtual network, so it may be overprovided and still causing congestion.
The GE-ONU and the router are currently connected through a CAT 5E cable, so I bought a CAT 6A just to see if that’s an issue at all.
Any other insights into the problem would be much appreciated!

I had similar issues with biglobe (who I was paying for internet) but really after hours on the phone, I needed to call NTT to solve it. I have no idea what they did but after I got a NTT technician to come out it was fixed. NTT service visit was free FYI. Im guessing NTT fixed some wiring (it looked like she ran a new line).
I guess you need to call them to reset something? The speed is slow like hell.
Sorry but are you 100% sure your on ipv6? I made a mistake thinking i was ipv6 when i saw on my router the option ipv6 and i choose connect with ipv4 over ipv6 and my internet become a bit faster and lower ping from 44 ms to arround the same as what you posted. But turns out that is not the ipv6. Have you used the username and password given to you by your isp?
To rule out that the issue is not that it’s going over PPPOE, maybe run a test at minsoku.net and compare the IPV4 and IPV6 speeds, then work from there?
Isps in Japan are notorious for throttling your dl speed between 6pm and 2am because it’s “prime time” when everyone is off work.
