Default [Q] WIFI only connects after reboot

I updated my wifes sghI747m to CM 10.2.1. It now will not connect to wireless unless rebooted. Once rebooted it connects no problem. It sees our wireless but will not connect. It was running 10.2 before without problems. Bootloader is MVLDLK4, Modem is currently MVLUEMK5. My update was as proper as I can do,wipe cache,dalvik etc. should I update bootloader to MVLUEMK5 as well?
