This morning I migrated from CloudScape to Vodafone and it looks like the process has completed. Last night before going to bed I simply changed the PPP details to those provided by Vodafone inside my DSL-AC56U and this morning I had internet.
Inside the router control panel I'm synching at maximum data rates of 79999 kbps downstream and 19999 kbps upstream and with speed tests I'm seeing fast ping times of 12ms with fast upload and download speeds, near maximum for this connection.
Despite the good data, it's all incredibly slow and taking a couple minutes on average to load a web page. I wondered if there is anything in the old configuration that might be causing this problem, since it was originally set up by CloudScape for their network? I have yet to try the Vodafone router, having heard it's pretty bad and it would be good if I could find out what is wrong here.
