@hed No, I don’t have a universal Gibabit internet, but rather one that is very far away from it. We live away from the village and Swisscom only brings copper over an overhead line and the performance is a maximum of 22Mbit/s.
A renovation to improve the cables in the house is planned but Swisscom isn’t doing anything because they don’t have to on their part.
What may tell you more than me are the diagnoses from the Intel PROSet Adapter Configuration Utility.
Cable test results [12/06/2022 5:50:49 p.m.]:
Cable Quality Status: Failed
Either the cable quality is poor or there is no cable connected. Possible causes: Bad cable, bad Anschluss, or speed/duplex mismatch. Make sure the speed/duplex setting on the switch/hub is configured for auto-negotiation.
Cable Integrity Status: Failed
The test found a bad connection. Distance to the problem: 225 meters.
So 225 meters, there is a problem with Swisscom.
Hardware test results [12/06/2022 5:46:18 p.m.]:
Register status: No errors detected
EEPROM status: No errors detected
FIFO status: No errors detected
Interrupt status: No errors detected
Loopback test(s): No errors detected
NVM health status: Failed
And that is the test for the hardware.
