Life's wonderful with our 2850 and all our Android/PC users - especially the engineer with the HTC One X that was causing the router to reboot - but now we have an iPhone and an iPad 2 that have connection issues: The iPhone doesn't get any DNS addresses and the iPad just drops/remakes the wifi connection very frequently.

Can anyone else chip in with their iOS experiences after firmware updating the 2850?

Thanks.

First if you have firmware 3.6.3 official you need to ask support (from what i am reading) to give a fix for the HTC one
If you have the beta all ready from them and still ahve some issues there is one here
ftp://ftp.draytek.pl/Seria_2850/Firmware/beta/ (3.6.3 rc1)
Polish FTP is not stating which is the fix but for my case using a samsung G3 updated to 4.1.1 and 2 iphones one of them is s model, no problems so far but will double check about the iphone issue
