Current router in my home network is older Linksys LRT214 gigabit router. Nominal speed should be 1000/500M. When using the LRT214 measured real speed is about 920/530M. When replacing the LRT214 with Teltonika RUTX10 router using exactly the same cables and connectors, measured real speed is about 630/400M. I am using CAT6 cables, so this is not a wireless connection. LRT214 supports 1000 Base-TX (IEEE 802.3ab/TIA/EIA854). I'm not sure if the speed difference due to this or should i choose some other Teltonika model to reach the same speed in CAT6-wired network? Or something wrong with the settings? In any case, i have similar observations about the network speed.
