I just wanted to let everyone know that NetGear already has a Release Candidate out for the R7000 to fix the 2.4ghz connection issues on their 1.0.6.X version firmware.
I have had it on my R7000 for a few days and it appears to have resolved the issue.
That being said this is a BETA so there could still be hiccups but according to Nifer on the NetGear forums this is the version they plan on releasing to the public shortly. Enjoy!
