I was having issues with my iPhone 5 with dropped WiFi connections and slow speeds as well. I was able to get a replacement and the issues have gone away.
I have Verizon FiOS and they use a proprietary router/modem so getting a replacement for that wasn't really an option. All of my other devices were having no issues connecting and/or WiFi speeds.
