Can never download with 3g - Galaxy S II Q&A, Help & Troubleshooting

I don't seem to have any major issues downloading and browsing when not connected to a wireless network, but I have noticed that I only ever seem to be able to connect through HSDPA, Edge (I think) or G. Whenver 3G is showing, the progress bar always hangs, before switching back to H and then continuing. So far I have never seen anything download via 3G.
I am confused. Why might this happen?

[Q] strange wifi problem

I am on bionix 1.3.1 and have noticed that whenever I turn my wifi on it seems to not allow me data access. My web browser will not connect to a page, market won't load, and any downloads that were in progress will fail. it's as if turning on the wifi is overriding my data connection and blocking it. It says that it's connected in the menu though. Any advice?
Thanks
Edit: I just noticed when looking at my phone stats, that when I turn on my wifi my mobile network state says disconnected, and it connects again when wifi is turned off.
Also, I have an airport extreme and a mac, perhaps that is my problem. I've scoured the internet and found a bunch of info about this problem, but haven't found anything that works yet.

Im sure someone will correct me if Im wrong but if you switch from wifi to 3g while downloading the download usually will fail because you were using only wifi to download the content and when that turned off it doesn't just switch to using 3g you have to manually retry the download using 3g .... when wifi and 3g are on wifi doesn't speed up the 3g instead it does the internet related work and the 3g does the text and phone call related work
that makes sense, thanks. as for the connection problem, it is definitely mac related. my wifi seems to work on other networks. I just need to figure out how to make it work with the airport. It's just weird to me that it says it's connected and shows signal bars, but won't access the internet.

so is the new problem that the airport extreme won't give wifi to your phone or that its not working at all
According to my phone I am connected via wifi to my network from the airport, however, the phone cannot access any internet functions when connected. When I disable wifi, it works fine with 3g or edge. It seems to be something with the settings on my airport, not the phone itself.

That's surprising maybe this means apple products are biased

Mobile network connection constantly fails on low signal

When I have one bar of signal its pretty much impossible to do anything online and with a 2 bar signal it can be hit or miss, browse the web, update apps, use a tether etc, the connection to the server just fails.
Using my old LG GT540 I could do anything online with a low signal although it was a little slow, I was wondering if anyone else had seen this, and if they have is the cause known, it could be my network I'm just trying to work out if its the phone.
It can show a HSDPA signal but data just doesn't get transmitted, I have also seen the HSDPA signal completely drop out before now with a 1 bar signal. Also has anyone seen it before the LFB update, but haven't after the update?

Atrix has problems recieving data from wifi

I connect to my WiFi network at home, and just to note, i cannot connect to it unless i am very close to it (within 2m) and when i move away, it still stays connected, but once i get to 2 out of 4 bars of connection strength, i can no longer recieve data, but it displays that i still have 2 bars. ( i mean that I cannot access any webpages or apps that require internet) In short the internet will only work if i am directly beside the router, and that is a problem. I am runnin Epinter's CM10 October 29th build. Does anyone know why and what i can do ?

It could be a setting in Wireless/wifi that stops device using wifi when it thinks the signal is weak. Have a look at that. If not that, have you looked at your router? Location ect

[Q] Wifi issues on LRX21Q anad LRX21R?

After updating to LRX21Q and LRX21R I get random disconnects on 5Ghz and 2.4Ghz. It sees the network and is connected but sometimes it drops it or I get the exclamation point on it without an internet connection. If I toggle wifi on and off or just switch between the two bands it goes back to normal. So far, I've only seen it while surfing in Chrome or streaming videos over my LAN. I didn't have any of these problems before on the previous firmwares.
Is anyone else experiencing this?
Same problem

Yep, i have the same problem while playing 8 Baal Pool. Other devices (nexus 5, ipad etc) do not have disconnecting problems.
Same here .. Sometimes I have to reboot to get it working again .
Ditto

Same here. Seriously irritating. :-\
I don't actually get the exclamation mark, but I do think I have the same problem. Sometimes refreshing Facebook or trying to display a web page or a Wikipedia page will take forever, for no clear reason. On another android device and the PC on the same internet connection there's no speed problem at all, and after a reboot it's solved on the Nexus 9 as well. It is indeed seriously annoying.
Got the same problem.
It used to happen sometimes on L but happens a lot more now that I have R.
I have to go to Settings/WIFI and select router again, also does not find router on initial boot up.

Slow Network with 3G - H

I found out, if i have bad Network, the Phone stays in it. For example, at work i have a Zone were only "H" is available and very slow. Phone shows 3G and i have 15KB/s DL Speed, wich is not really usable.
If i move to a Zone were it is better Network, it still stays in "H" and i still have only 15KB/s DL speed. But, if i set my Phone in flight mode and back, then i have "H+" (Phone shows still 3G - wich is normal) and DL Speed increases to over 4-5 MB/s and more...
I think there´s a problem with Network Selection, so Phone does not immedialy take the fastest Network, it stays in slow until the user makes a manually reconnect with flight mode of on or like you described with choice of Networks.
This is really disturbing, because at work i always have to set flight mode on and off and wait till connection and then its possible to surf in the internet etc..... before its so slow that you wouldn´t really enjoy surfing in the internet...
Anyone has a solution or a fix for this?
Its really annoying all times to switch flightmode to have usable internet...
No Idea anybody or a tweak?
