4.3 Update - Wifi Issues

[Amrit]

Hello,

Need some help. I recently got the OTA update for 4.3 and I've noticed my Z1 can't hold a wifi connection at all. Its gotten really bad now and unless im literally standing next to a router it disconnects then reconnects constantly. I also get a message called "association rejected", whatever that means. 

Thinking about returning this and getting a note 3 instead, seems like such a dumb problem to have! Pls does anyone have a fix!

Can it be fixed with sus? Have you tried that? I mean that solves most of the problems. For the Note3 awesome Phone bit give your Sony a change it might be fixed and you will have am awesome phone. Mine had fc problems and a very poor wifi connection now it's great. Wait a while and if it is not better after sus well even would return it. There is nothing worse then a unreliable phone.

Can you expand on what sus means please?

I am experiencing this exact same problem on Xperia Ultra.
