Help with TP-LINK and Vodafone Sure Signal 3

Hi
Ok here's where I am, I had a TP-Link W8980 on a BT Infinity connection. worked ok but had to use a BT modem which was not very reliable so I got an Archer VR2600 and that was great BUT the SureSignal does not work. I have tried both DHCP allocation and static IP, done the port forwarding but all to no avail. Of course Vodafone blame BT and vice versa, if I plug the unit into another BT ADSL it works fine, trouble is BT routers are awful and my office VOIP phone will not work, we think due to SIP ALG.
Vodafone are saying and I quote "That they are getting an authentication failure on the VPN it sets up as the dynamic IPSEC packet is being fragmented".
They do state the MTU needs to be 1500 and one guy on the Vodafone forum is adamant that this is the case, however TP-LINK support are saying the max is 1492, the BT modem that does work is set to 1500.
Anyone got any ideas? I no have 5 phones with no signal!!
Cheers
