I have spent my whole day troubleshooting my home network. And I'm out of ideas.
Configuration:
PC (SERVER) o---------------->[SWITCH - Netgear 10Gbps]o--------->[ROUTER - ASUS ET12] ---->> WAN ( 1000/1000 fiber)
2.5Gbps cat7
The problem:
(On Windows 11) I get full Upload/download in the Malmö area, but very low speeds outside Sweden. (200-300down / 100-200~ Upload)
while
(On Linux Virtual Machine inside the same Windows) - > Speeds remain high outside Sweden ( 900/900 Down/up even 1000+ Km)
What I've tried:
-Reinstalling and updating Ethernet adapter
-Adding an USB-C ethernet dock (weird results, downloads gets lower, upload a little better)
-Moving PC Lan connection from Switch directly to Router (It improved speeds by 100%, but still not close to full potential)
-Testing download from Dedicated server in Holland (Trough switch: DL 20MB/s Directly to router: 60MB/s)
-Testing other devices on the network - LAN (Apple tv trough switch = 900/900) and Wifi 6 (iphone and imac on wifi = 900/900)
-Restarting into Safe mode with networking (no network at all)
-Running Linux in VM (Speed 800/900 on server 2000km away)
-Running Win10 in VM (Speed 800/300 on the same server)
-Changing Ethernet Cable
Why does it matter ?
It's a legitimate question. I'm running a nextcloud server trough which I share a lot of files (pictures, videos etc) that backup directly from our phones in the household. Which families afar are sharing further etc. Also I run a plex server for the family.
With all that in mind I got 1000/1000Mbps subscription to make the experience as smooth as possible.
But it appears, that I'm able to effectively use 10-20% of that bandwidth from outside of country. And as seen from above, it's not the Operator's problem, it's my PC's problem.
I'm running out of ideas, and any suggestion would be more than welcome!
Sorry for the resorting to English, so far my Swedish works mostly vocally in conversations, but didn't really want to butcher your language in writing.
Mvh,
