R7000 2.4ghz not working but 5ghz is fine

I ditched my R7000 after months of you not getting any fixes out, I made the huge mistake of getting the R7800 it has issues with iPhones and iPads (sorted in beta tests but it should not have been released like that) and still you failed to roll that into Mays update. Frankly the fact you are using OpenSSL versions from 2005 and not even keeping up with the latest OpenSSL CVE's (https://www.openssl.org/news/vulnerabilities.html) leaving routers potentially vulnerable says a lot. I think I'd be better off with an Asus router which gets patched regularly, has useful things like the Trend engine that looks for malware, has a HTTPS login page which you cant store the password on and even lets you change admin to something else less obvious.
Don't get me started on the tired GUI of all your routers, Netgear firmware is appalling and after banging my head like many other users you still have a borked version of IPv6 as you drop certain ICMP packets that should not be dropped. Asus and other companies seem to at least try keep their routers safe and up to date and have working IPV6, Netgear also just drops EOL on routers like the R7500 and brings out a v2 and look how little support that unit has got! Considering the price of the equipment it feels like you are just into the bottom line and it feels like your coders are vastly inexperienced, I mean how long does it take it you to update to the latest OpenSSL versions? The R8500 using OpenSSL 0.9.7f 22 March 2005 (software that is 11 years and 2 months old)  is outrageous let alone taking into account that routers huge price tag you think you would get the latest OpenSSL version and better and more frequent firmware updates.
