7390 should have gigabit Ethernet, although it probably won't be able to route gigabit, those speeds look exactly like you have a link somewhere only negotiating 100mbps. Even on the 100/20 plan you should consistently get just over 100mbps download - weird that you were seeing 100/10 (or I'm assuming 93/10) before the upgrade.
Yep it seems like thats it. I can transfer files between my PC and NAS fine at gigabit speeds (both go through a switch), but anything from the switch to the internet via 7390 seems to be capped at 100. Even in the Fritz Box settings view, LAN between it and the switch shows 100Mbit even though the port is set for 1Gbit. Yes previous was roughly 93/10. So you are correct that it cannot route gigabit by the looks of it
