So currently we have a VDSL line with VDSL wifi which our provider gave us. The signal in the room where the router is is good but then the connection strenght in other rooms is awful. I was looking at some VDSL2 wifis and they are kinda expensive but i saw that ADSL2 + wifis are cheaper and my question is that if our VDSL line will be compatible if we buy one of ADSL2 + wifis ...
