Why is my WiFi so slow at work?

It Works ok if im less than 5 meters away from server. But anything over that and its unusable. I work about 10 meters from the server. And I get at least 2 - 3 bars of signal out of 4. And I can't even post a comment on here. The speed is very fast for about 30 seconds and then ridiculously slow. It also struggles to connect. Tries about 3 or 4 times before it connects. I'm running cm10 on s3 but have this problem on stock, omega and checkrom. I had simular problems with the s2 aswell but not s1. I don't want to use wifi kill as its my work and it might not solve the problem. Is this the s3 working on networks with multiple apns? Is there a code I can call to turn off power saving ?? Can't force to 5ghz either.
Some advice would be massively helpful. I am getting very frustrated.
Thanks in advanced

WiFi issues

Just got this phone and the WiFi connection seems to disconnect every time I'm using it. It recconects in seconds but is annoying because its constantly dropping the connection. Not a router or modem issue because my iPad and my sisters gs3 work just fine with the WiFi. Any solutions?

Router settings:
Authentication method: wpa2-personal
WPA encryption: AES
It has to do with your router. For some reason some routers with some settings do not play nice with the dna.

I forgot to mention, It does not like an unsecured connection
is it doing this all the time or only at night cause HTC included smartsync which does this to data and wifi from like 8pm-6am. If so get https://play.google.com/store/apps/details?id=com.jonny.smartsyncdisabler from the play store enable it and reboot and problem solved. If you think its your router what model you have because it probably isn't.
