BTHub 3.0 Replacement

Hi, i am looking for a new custom router if it's possible, I am on BT Infinity and im using a BTHub3.0 along with the white openreach box. I am looking for something that doesnt need to be rebooted every few hours and that doesnt keep dropping wireless signal.... Also was told that my router may be blocking a port and stopping me from streaming to my galaxy s2. If anyone knows what would be the best replacement please do let me know..... Thanks
