Ok, to cut a long story short, I tried a Draytek Vigor 130 modem which didn't like my Huawei cabinet, completely f****d my line, DLM kicked in and lots of other things went wrong. I returned it and after quite a bit of research, bought a TP-Link TD-W9970 with a broadcom chipset and supposedly supporting bridge mode, G.INP and Vectoring. So far so good, the line is stable and things are going well, improving gradually even. Problem is my setup depends on MTU 1508 for my IPv6 tunnel to work. I would expect to be able to ping packets 1472 but can only ping 1464 suggesting the MTU is 1500. In bridge mode, I don't seem to be able to change this MTU. Can I change it or have I bought another dud?
Thanks in advance.
Michael
