I have the following configuration:
a 100mbit router connected to a gigabit router(TP-Link WR1043ND) in a LAN port (WAN ports are empty). DHCP is disabled on the gigabit router so it is just making a wireless network (300mbit) and is working as switch.
I'm testing with my local network behind the gigabit router. I have my desktop connected directly via a cable, and a second desktop connected via a gigabit switch which is verified to work at 1gigabit. I would expect data transfers to be higher than 100mbit, but the transfers are capped at 100mbit. I also checked this with a tool called LANBench.
So then I wondered probably the 100 mbit router. So I removed the connection from the 100mbit router, enabled DHCP in the gigabit router, and tested again. Still capped :(
Is there a reason why the speed is limited, where can this be?
