Connection/loading issues: nothing wrong with OpenReach line

[#1 · Accepted solution]

...identified that it was the Static IP address you've had for a long time causing your connectivity problem for different webpages, devices and services. As shown on our log your line had two active online sessions - one with your Static IP and a second with a Dynamic one - so internet traffic returning to your router was getting confused between two different IP addresses.

Plusnet need more Mani's!

Does that suggest that you've previously had another Plusnet router (that someone else is currently using), which still contains YOUR Plusnet account username and password, and therefore there are two independent internet connections logged onto your account.  Whichever router established it's PPP connection first would have got the static IP address, and the later authentication would get the dynamic IP allocation.

A passed on router does not need to contain the username and password.  If it is connected to the Plusnet network (was passed to another Plusnet user) and Plusnet has not been advised that the router has been passed on, the automatic configuration of the router (by reference to the serial number) WILL be that of the donor's account.

Brilliant out of the box thinking by the CSA to look at the number of concurrent PPP sessions against the account ... or was it two connections on the same line?  That would infer that one or more routers had established a PPP session ... something does not add up here!

However, if the two session had different IP addresses I do not understand how that will have caused the issues reported.  Connection responses should be returned to the sending IP address having no bearing on the associated user account.
