Disabling this setting resolves the issue.
Problem: Sporadic issues during Ethernet negotiation between PC and
R&S TSME6 with some USB-LAN adapters using a Realtek RTL8153 network
chip
If PC and R&S TSME6 are both powered on and physically connected with a LAN
cable, and the LAN LED 2 of the device (see Table 3-5) does not reach its yellow state
after a few seconds, and/or no connection is visible on the PC side, and this event
occurs sporadically, this may be due to an issue with the USB-LAN adapter not always
completing Ethernet negotiation successfully.
Usually, forcing a new Ethernet negotiation is enough to solve the issue (e.g. by
unplugging and plugging again the Ethernet cable). A workaround for this issue is
implemented in R&S TSME6’s firmware since version 05.06.10.00, it is recommended
to use this version or a newer one.
Problem: Sporadic issues with R&S TSME6 not responding to connect attempts
from PC after Ethernet negotiation is completed when using a USB LAN adapter
based on a microchip LAN7800 network chip
If the PC and R&S TSME6 are both powered on and physically connected with a LAN
cable, and the LAN LED 2 of the device (see Table 3-5) has reached its yellow state
after a few seconds, and no connection to R&S TSME6 is possible, and this event
occurs sporadically, this may be due to an issue with the sending path from the USB-
LAN adapter to R&S TSME6.
