Hello. We have a peplink 710 (firmware 5.4.9). We recently updated one ADSL line 24/1 Mbps to VDSL 50/5 Mbps. I updated the WAN connection. But when i download big files, the device disconnects the line and connects again. download stops. the disconnection doesn’t have to do with the provider, i checked. it happens when someone downloads something. is there a compatibility issue with VDSL?
