Ever since I purchased my Nexus 6, I have had trouble with a data connection at my office. My signal strength will show half of my bars for LTE, but I still can't load webpages, or I'll have a bunch of queued notifications or messages come in at one time. I haven't found a fix for my LTE signal, but for a while, I had a work-around. I would go to Settings>(Under Wireless & Networks) More>Cellular Networks>Preferred network type>(I would disable 4G/LTE and only use a 3G connection). My 3G connection was far more reliable.
Since the Android 5.1 update, the option to disable 4G/LTE has disappeared. I now only have options for "Global," "LTE/CDMA," and "LTE/GSM/UMTS." None of these options allow me to disable 4G/LTE, and use only 3G.
I've contacted Google's Nexus Customer Support, and I've been told it's an issue with Verizon. Does anyone have any suggestions?
