== Changing the Line Rate ==
 
This sets the line rate on your line:<br />
This change is applied the next time you connect (Re-PPP).

== Stability Options ==
Forces an MTU regardless of what is negotiated by your router.
 
'''More Info:''' MTU is negotiated upon connection. We usually like 1500 MTU, however, there can be situations where forcing 1492 MTU is required. For example, if your router negotiated 1500 MTU initially but you make a connection to a server that want'swants to re-negotiate a lower MTU it will try to do this using ICMP, but if your router has a miss-configuredmisconfigured firewall that blocks ICMP this can't be re-negotiatedrenegotiated and the connection to the server will have problems. This is seen when connecting to certain web sites, bank web sites and https sites. Forcing 1492 MTU from the start means that all your traffic is in packets of 1492 bytes and so won't have this problem.
 
=== TCPFix ===
[[File:LineOptionsLCPFix.png|none|frame|Re-negotiates PPP after acquiring the connection from BT, who may provide 1500 MTU when it should be 1492 MTU.]]
 
'''More Info:''' During the PPP connection when your router initially syncs up and logs in to us, the PPP connection is passed via BT. Sometimes BT can change the MTU. With this option we will accept the PPP connection from BT, but will then re-negotiaterenegotiate the PPP connection with your router allowing the MTU to be reduced. On TalkTalk connections the MTU is always negotiated as 1492 MTU, you will need to select LCPFix and 1500 MTU to fix this, otherwise the LNS will use 1492 MTU when renegotiating. This is sometimes called 'LCP re-negotiating.negotiation always'
 
=== FastTimeout ===
[[File:LineOptionsRate100.png|none|frame|Uses an LCP Echo timeout of 10 seconds rather than 60 seconds before entering the LostCarrier state.]]
 
'''More Info:''' LCP echoes usually stop responding if the line has gone down. Our LCP monitoring, which produces the graphs, will drop the line if there are no replies after 60 seconds. When [[bonding]] or used in a fall-back setup, having a faster timeout is useful in order to fall-back quicker.
