I've just migrated my connection from BT Infinity to Zen (go-live was this morning)
Previously i was getting a solid 78Mb/s down & 17Mb/s up..
I'm now getting 57Mb/s down & 17Mb/s up
I'm not using the ISP router (just changed the PPoE details on my Unifi USG), Is it usual for the the line to re-train when you migrate connections? Or do I need to speak to Zen?
Everyone you change ISP it will cause a DLM reset back to interleaving so you will have to wait a little while for it to optimise the line now.
