Wireless option for rear surround speakers? 7.2.4


Hi all I run a 5.2.4 home theater but want to upgrade to 7.2.4 without having to run wiring to the rear. Is there a good option to add the surround back speakers that is wireless? I tried svs soundpath and that failed miserably. Connection issues and interference with my av processor's wifi. There doesn't seem to be many options that are on a dual broadband for example to get away from the 2.4ghz.

I know someone that tried the Dali but couldn’t eliminate a time lag between the fronts and the rears
@mahler123 yes I think it would be difficult without the use of room correction programs and the ability to set speaker distances which then you could set it farther to allow for the time lag. I have never had to deal with that before. Thanks for input.
