Any VDSL router is compatable with Infinity. TP-Links seem popular with many on this forum. As to which model to get it depends on your budget.
This is the one described TP-Link TD-W9970 N300
It will not work, the home hub 4 only has an ADSL modem inside, not a VDSL one. You need a VDSL one for BT Infinity.
They are absolutely adamant that the hub we have will work. You guys say I need a modem but I thought the homehub 4 had a modem built in. Who's wrong here?? They're saying there's no fault and we just need to wait longer for it to setup....
They are talking absolute rubbish, only the HUB5 and HUB6 have built in VDSL modems. Who are 'they' ?
