I have a SOHO LAN with 10 PCS and 7 Synology NAS units (all different models). A lot of data. I am upgrading it from 1 GB to 2.5GB.
The router, switches, PCs, and 3 of the newer NAS units all run well at 2.5GB - the extra speed is very helpful.
My remaining problem is with 4 of the older Synology NAS units: DS1813++, DS1019+, DS720+, DS716+II.
I hope to upgrade these using UGREEN USB to 2.5Gbps ethernet adapters (with a Realtek RTL8156BG chip).
I have found suitable drivers for each of the NAS units (on github), but need to run an SSH install command to force the NAS units to accept the drivers.
I have absolutely no idea how to do this. (PuTTY?) π¦
I don't have an SSH terminal.
Advice please!
