Also bought an Iplate and fitted it.
Pre Iplate, download speed was checked at 1.4 max going down to .7 at times. Post Iplate, download speeds checked at or about 1.9, so, something like a 33% increase. Subjectively, it doesn't seem any faster and I still have the constant dropouts,freezes etc. but it would seem to have some sort of improvement effect. Would that one could fit a similar adaptor to Orange and their awful 'service'.
