Upgrading my account question

[#1]

On my next billing date i will be upgraded from the Value package to the PlusNet Extra package. I didn't order a new router during the order process as I already have a ADSL2+ one so it should work fine!
My question is, will i have to reconfigure my router when the upgrade time arrives, or will it simply work without me lifting a finger?
thanks in advance

The only difference in the two packages is the monthly allowance, so no changes required in your router or email software, etc.

I think apart from the bandwidth displayed by VMBU changing the only thing you might notice is that the PPP connection to Plusnet (not sync with the exchange) drops for a few seconds soon after midnight at the start of your billing day. That covers switching you to the Extra traffic management profile. As Jaggies said there shouldn't be any need for you to take any action.
