Have been living with a 1 or 2 bar signal since upgrading to the NEW dual band router from Verizon on my iPhone 6. Recently at a friends house and they are using a Linksys 5 Ghz router I was getting 4 to 5 bars and superior speed one floor removed from the router location. So what gives? I sit my phone next to the Verizon router and same result. Removed the LIFEPROOF case on phone, no better. My phone is also from Verizon so I can't say there is a mismatch somewhere. The forum here shows other people with same issue but no solutions. All software is up to date as well.
