It's my understanding that Verizon has admitted that the 4.1.2 update is a causing a "recognition problem" for older wifi routers. If you are having problems with wifi on your RAZR, try upgrading your old a/b or a/b/g wifi router to a newer b/g/n or b/g/n/ac version (yes, 802.11ac wifi routers are available now) and you should be fine. I have a RAZR MAXX HD running 4.1.2 connected to a Cisco/Linksys E3000 (a/b/g/n) router and I am not having any wifi problems with my phone. In fact, my WiFi Analyzer app shows greater signal strength on my MAXX HD (-40 dBm) than I ever got with 4.1.1 running. I use Cox as my ISP and my Speed Test app results are as follow: Download 24.90 Mbps / Upload 5.39 Mbps / Ping 16ms. Pretty decent bandwidth I'd say.
I was it was that easy. My router is Cisco E4200 and is less than 8 moths old so I don't think its the cause. Besides the WiFi on my Razr won't even toggle on. When I do this from the system menu, it will toggle on for a sec or 2 before turning itself back off. I've factory reset before so I know what's involved. Usually leave that as a last resort. Thanks for the suggestion with the router
