   - You always telnet to the modem_IP, which counter-intuitively does not have to be unique on the network. In the default configuration, you would use 192.168.0.253 on all modems when connecting via telnet
+On windows you can set MTU in an admin command prompt with ''netsh interface ipv4 show interfaces'' to get the interface name, and ''netsh interface ipv4 set subinterface "Ethernet 3" mtu=750 store=persistent'' to set it.
+On linux MTU can be set temporarily with ''sudo ip link set dev eth0 mtu 750'', to persist after reboot depends on how you manage network settings (systemd, /etc/network/interfaces, NetworkManager etc.), but for example with NetworkManager you can do something like:
+<code>
+sudo nmcli connection show
+sudo nmcli connection modify "Wired connection 1" 802-3-ethernet.mtu 750
+sudo nmcli connection show "Wired connection 1" | grep mtu  # verify
+</code>
