ADSL2+ synch with netgear modem-router

[vsp]

I have fusion ADSL2+ service from sonic. I have a netgear DGN3500 modem-router which supports ADSL2+. The sonic tech tells me I'm synched to ADSL2 (not 2+) which is controlled by the modem, not sonic.

So, how do I get the modem to recognize ADSL2+? I can find no setting to deal with this.

If you aren't already running the latest firmware I would recommend updating to it. If you are, I skimmed the documentation and I see no mention of any configuration options (or status output) from the router. You might be able to get somewhere with Netgear support but it may also be a good idea to verify that all of your filters are ADSL2+ capable.

I am running the latest firmware. First thing I checked.

You're right about the documentation. Modem sync is automatic. It will sync at ADSL2+ automatically if the ISP is delivering a ADSL2+ signal. It reverts to ADSL2 if not, and to ADSL1 if it can't get ADSL2. No user control on this although I'm still hanging a bit with netgear, but that's how I understand it.

I am using ADSL2+ capable filters, at least sonic tells me they are ADSL2+ capable; I bought them from sonic when they told me I needed new filters.

I'm reasonably convinced that it's not on netgear. It appears to be a problem with sonic promising service they are unable to deliver.

Our DSLAM default configuration is "multimode", which allows the modem to negotiate whatever it decides is best. We can also lock to a specific protocol; ADSL1, ADSL2 or ADSL2+, so that might be worth a try. Ring 611!

Also, not all modems are created equal. It might be a good idea to swap the modem out for testing with another (preferably one we sell - they are well tested for performance and stability) to see if it behaves any differently.
