Hspda+ question - AT&T Samsung Galaxy S II SGH-I777

Hey guys I have a question recently my phones inter has being acting crazy. It's connected but it's slow and I would check the status on phone settings and it would say umt or hspda+3-6 now my connection is even worse and when I do get data the Hspda shows +15 (hspda+15).
Does that mean something? I never seen the number go pass 6 til now.

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

3g icon showing while on WiFi

So this is probably a dumb question but I have nevr had it happen before. My DNA the last couple days intermittently has been showing the 3g icon even while I'm connected to WiFi. I'm not sure but is that a bad thing or not?

If you send or receive a MMS while on WiFi your data will come on for a second or 2

Thank you. I honestly wasn't aware of that. And I was sending a panorama photo I had just taken around that time. Good to know.

I have the same thing happening but it's on 4G and 3G sometimes, usually it doesn't show any data transmission but just seems to stay on doing nothing for several minutes. Mine does stay on until I shut off my mobile network and when I turn the mobile network back on it stays off. With no text messages or anything going through.

Polling rate?

Is there a way to modify the wifi and mobile network polling rates? My phone dies like a dog at work due to no reception.
Thanks

Wi-Fi scan is a tweak in build.prop. There is a app called .prop tweaker or editor I believe.
Idk about network though

Whenever I'm in a poor signal area I just turn off mobile data and wifi. That way you don't have to worry about your radio constantly searching for better signals when your not even using it.

Yea just turn off data and WiFi. I saved HUGE amounts of battery doing that in bad signal area

I just turn my phone off completely. Great battery life, and I never have to worry about it searching for signal. Bonus: with all the new kernels popping up, when my phone is turned off it sleeps like a sloth.
Try it out!
Appreciate the replies but i use offline apps all day so i can't power down.
Anyone else know?

Notifications not coming in on wifi

So I'm new to the Note 2 and when I'm at work I am connected to their wifi because my cell sign lapis horrible when I'm there. But when I get off, I seem to get all my push notifications all at once like they were waiting for me to get off wifi. Anyone know the reasoning behind this?

Maybe your phone is just using the WiFi connection without actually trying to use VZWs service because its so crappy.
If you're unlocked and have flashed a ROM then it could definitely be a ROM issue.

I'm currently running stock but plan on rooting tonight. My signal is really bad in the office so that may be the issue.
