Check your speeds daily for the next 10 days. They have a habit of 'training' back to a slower speed.
Every 15 minutes for the next ten days, information on logon and sync 'events' are passed to a Rate Adaptive Management Box (RAMBO) at the exchange and this collated information is analysed to calculate your MSR (maximum stable rate.)
The MSR is calculated then (based on the lowest speed/rate you get over the next 10 days) and rounded down to the closest 500k. At the end of ten days this info is then transmitted to the Rate Adaptive Profile (RAP) and to your ISP.
So don't get too excited about your new sparkly 4.5meg. Wait until at least 10 days time.
This is the filter you should have. It is the one BT engineers will fit. Do NOT touch the wires in the NTE5 box. Just screw the new faceplate/filter in place of the existing faceplate otherwise you are tampering with BT equipment. (Everything up to and including the NTE5 box is theirs. The faceplate/filter is OK for you to replace so long as it is a BT approved item.)
Remember if you have the older NTE5 box with nice machined screws then you will need these as well for 20p extra. (More modern NTE5 boxes use self tapping screws.)
You may want to ask BT/Openreach to fit a new NTE5-A box and filter splitting faceplate with bell wire filter. These run cleaner than your old NTE5 box.
