Prepping Linksys WAG160N for ADSL2+

[#1]

Received an email from PN saying they are performing a bulk migration to ADSL2+ in Jan. According to the approved hardware list http://community.plus.net/library/hardware/adsl2-hardware/ my WAG160N is compatible.
Is anyone able to tell me what settings I should check so I have a seamless (problem-free) transition when they perform the upgrade.? PN support mentioned making sure something on the router side was set to auto so just want to make sure.
Thanks!

Hi there,
I don't think you need to worry about any settings, if it's compatible it should just work for you when the changeover happens

I just left mine set to auto  and it works well on adsl2+
note I turned of the UPNP and it does improve the  thoughput.
