SP3361/SP3364/SP3367 supports ADSL and is compliant with ADSL2+ standards but why it takes much time to setup connection?
This router supports several connection modes. It detects the ADSL mode while connecting to service provider. The sequence is Auto Sync-up, ADSL2+, ADSL2, G.dmt, T1.413, G.lite. If you have ADSL G.dmt service, the fourth in the sequence, it takes a little more seconds to set up the connection. You can configure the router using G.dmt to speed up rising the service. The route is Advanced Setup –> ADSL. Switch ADSL Mode to G.dmt.
