Do you have problems during streaming Youtube videos?
Do you notice a very slow connection with your Nexus 4?
Do you notice that your other clients (like notebook, other smarthones, pc, etc etc) are connecting very well with the same router's settings?
Good, the problems are not inside the router's settings. The real issue is neither into the Nexus 4's Qualcomm WiFi adapter.
The issue is only in a configuration file named WCNSS_qcom_cfg.ini.
You have only to flash the zip file through recovery.
If you don't notice the difference, if this zip file is not helping you, please write here and you can always flash the stock/default settings.
