Galaxy Nexus Wifi Problems

[GalaxyUser230]

I've had my galaxy nexus for about 6 months now and within those 6 months we have gotten a new router which I don't really know if that has to do with the problems my nexus is having but its a great phone but the wifi has been dropping laitly. its gotten to the point where I can barley even use the wifi so im usally on 4G. But there are times it'll work and then it times out and stops working for a couple minutes. it's still running 4.1.1 stock android I think I do have the bootloader unlocked. I've searched the forums for solutions on how to fix this and if any one else was also expericing these problems like mine and have not found any so I would highly appreciate it if you could give me some insight on how I could fix this problem! - Thanks!!!!
