In my house (built 2007) I have several Cat7 cables (S/FTP PiMF) from Room A,B,C, ... to Room X. On all (tested) cables I get a 1GB connection (cheap home type 1GB switches), only on ONE I only get 100 MBit (most likely I folded the cable a bit to much while placing it).
I wonder if there is a switch (or other device) that could get a 1GB connect on a "poor quality" cable? With powerlan going up to 500MBit, there should be a solution >100MBit if there a 4 TP lines, shouldn't it?

PC connects to switch with 1GB. Switch connects to second switch with 100MBit (other cables in same config work 1GB). Patchcable is Cat6. Wall-plug is Cat6, fully shielded (same as all others in the house).

Still 100MBit. Tried two switches: EDITMAX ES-5500G and Longshine LCS-7108A, same results. I also reconnected the cable to the patchpanel, same result.
