The thing is it doesn't turn off the 4g radio once u connect to the wifi it shows both of them connected and when I try to use the speedtest app its testing the 4g connection then changes to wifi

I saw that this morning. It just took a while for it to actually switch over to wifi and I don't think the 4g icon ever went away.
I'm trying my best not to use wifi because I'm testing T-Mobile's service to see if it works for me.

I'm having a similar problem. I have a terrible T-Mobile signal in my house so I always have wi-fi enabled. I've noticed a couple of times that my phone tries to use the mobile data instead of the wi-fi data even though I have no mobile signal and full bars on the wi-fi. I have to either go to airplane mode, then re-enable the wi-fi, or un-tic the "use mobile data" box in the wireless settings, and then it will switch to wi-fi and it works fine. I've had the phone for two days and this has happened twice.
One other thing I've noticed is even when I have a good signal, MMS is reluctant to send over the mobile network. If I reboot my phone and then send the message it sends right away.

It also takes a while for it to switch to wifi for me as well. Once it's on, it's on though. I noticed that to enable it quicker, turn it on and go into Wifi settings where you see all the available networks. It appears to connect instantly from that screen.

Yes this issue is starting to get real annoying. I powered on this morning and both wifi and 2g connected. 2g wouldn't drop until I toggled the data connection

Wifi hotspot app issue

Running heinz 57 rom on cell south showcase. Whenever I turn on hot spot, I lose my data connection. Devices are able to connect to my phone no problem, but obviously internet not working for those devices.
Wireless tether works fine, but it is only for one device and uses wep instead of wpa.
Anyone had any success with this?

I have same rom and phone and mine does this also. But wireless tether does work so no biggie.

Yeah, was just hoping to get better encryption and ability to let more than one person connect.

your problem sounds like an apn issue or provisioning problem.
are you using a stock phone? what apn is selected?

I have a similar problem. I loose data out of blue. Called Att and they informed me that my data was removed for some reason. They reconnected but ever since than, I loose data for no reason. I have to reboot the phone. Even than, my data works for only 10-30 mind and disappears. When that happens, I have to call ATT and the disconnect my phone and reconnect and it works fine for a while. I've called them 4-5 time in last few weeks. They think its the phone. They are going to send me a replacement.

[Q] wifi no longer working??

Ive had my 300 for about 2 weeks now, no issues nothing, its not even rooted. Everything was working fine till about 2 days ago when the wifi would not connect. I would restart the 300 and it would stay connected for about 30 seconds or so before it would disconnect. Whenever i would go to the wifi screen and select connect it does nothing. Any ideas?

Try deleting and recreating your wifi connection. Get it once in a while with my phone.

Get Wifi Analyzer and make sure you're using a clear channel. There could be interference from another wifi network.

My wifi keeps disconnecting and reconnecting

Ever since my device got bricked and flashed the the original firmware, my connection on wifi keeps disconnecting and reconnects even though im like 10 feet away from my router. This bothers me because I cant play online games. Is there anyway to fix this?

I suggest you turn off your router (or also disconnect the cord) for 30 seconds, turn off your WiFi on your phone, then plug it back in and turn on your WiFi again and check. Otherwise it might be a phone problem.

I'll give it a try
...When im connected to other wifi network this doesnt happen.

You should consider buying a new Wireless Router which is more powerful. As your statement, that this issue doesn't happen in other WiFi network, try to check the speed of your internet, traffic, etc.

My other devices works fine

try to forget the network, restart your phone and connect again.

So the issue must be the communication between your phone and the device. Try to restart the phone, or remove your wifi, and then enable it again.

try this
go to settings> WiFi > advance > keep WiFi on during sleep > select always on

I tried, the problem is still there

problem solved and a question-why does unstable wifi mess with usb?
My phone kept getting disconnected from my computer. This was apparently happening because my wifi was unstable. Not sure why the phone disconnected, I was connected via usb. The wifi was unstable because I was using a proxy. When I use my comcast connection straight through the problems go away. If someone can explain why an unstable wifi can screw up a usb connection I'd be grateful. Windoze issues?
