shame about my experience, I will try to report what happened to zyxel and if they provide a fix will test it, the dsl driver looks a definite improvement tho, so hopefully if my billion ever arrives that will be better.
Normal browsing was an issue as well I had to keep refreshing pages on here, submitting posts multiple times etc.
Of course its possible it may be an issue with the asus router I am using but that does work fine with the hg612.
