I recently got myself a DSL-AC68U modem/router after having issues with my HH4 on my Infinity 2 line. It all started with the HH4 logs showing "PPP LCP Send Termination Request [User request]" every time my net dropped out which happened randomly (sometimes multiple times an hour, sometimes only once a day). Reading many forum threads on the same issue I saw it spanned across the HH5 and the HH6, and most had better results getting 3rd party equipment instead of getting replacement HH from BT.
I had been in contact with BT to be told everything was ok with my line and was told to get the new superhub.. I also did the quiet line test everything sounded fine to me, no crackling noises.
I got the new router Friday 22nd so honestly it could possibly do with running for longer to settle in(?). Saturday all seemed to be running fine and my first DSL stat results were

WAN Connection: Ethernet link down.
stop_nat_rules: apply the redirect_rules!
WAN Connection: WAN was restored.
start_nat_rules: apply the nat_rules(/tmp/nat_rules_ppp0_vlan3880)!
Checking my DSL stats later in the day I noticed the path mode had changed to interleaved -

One thing I didn't do when setting up my router was a factory reset after updating to the latest firmware. I have a very basic knowledge of everything since looking into my broadband issues but most of it is going by information from other forum posts, so excuse any misinformation. I was wondering if anyone could help or suggest anything I should try do. Below I am listing some questions and additional info.
- Could a factory reset help, should that be done after a firmware update anyway?
- Before a factory reset should I just let the router run for longer to see if it returns to fastpath.
- Could the new hub connection drop that I posted above be the same connection drops I was getting with my HH4?
I noticed my first DSL stat screenshot is showing a lot of CRC errors after only a short uptime. I understand this likely caused the line to change to interleaved DLM.
On my HH4 besides the annoyingly random connection drops, I was getting about 74 down 18 up and around 8ms, and the same speeds with new router plugged in. Since interleaved is in place I am getting around 66 down 18 up and 22ms, hopefully caused by something simple like wrong DSL settings which currently I haven't touched.
