Page 7 - the link above, has a download to a generic Ralink 3.3.0.0 firmware image.
Try that out and see if the I-Phone issues occur
Note - this is a Generic Image - and as such, you're taking a risk, as usual.
Worked on my WHR-G300N - loaded fine - a bit different config than DD-WRT.
See if I-Phone issues occur with this build. _________________ Soylent Green Is People !
