Firmware causing wireless 2.4 Ghz to not allow any connections. I have updated my firmware to the latest V1.o.2.144. Upon upgrade my device lost all wireless connections and some ethernet connections. I have T/S and discovered the following. If I turn off the wireless transmitter for the 2.4 Ghz - all my devices come on line 5 Ghz and ethernet connections. If 2.4 Ghz is on without security (none) everything connects also. With authentication (security) no devices connect wired or wireless. I have tried reverting back to all the previous versions (.136, .134, .130) none of these work with the 2.4 Ghz active with security. Here is the kicker. V1.0.2.128 works perfectly with no connection issues. This also resolves hosting issues when gaming. This is OBVIOUSLY a firmware / software issue! Due to the fact that my devices connect on an older version of firmware! So the hardware works. NETGEAR please investigate this issue as there are LOTS of posts about the connectivity issue since update!
