Lock 3G signal - Windows Phone 7 Q&A, Help & Troubleshooting

Is there any way to lock my Optimus 7 into 3G signal and not let it fall back to EDGE/GPRS when 3G is available with weakest signal? Happens a lot and its annoying.

The default behavior is to use the highest-speed connection. If it's falling back to EDGE, that's almost certainly because the error threshold was too high for useful connectivity.
There is a way to turn off 3G (which is also much more battery-hungry) but I don't know of one to turn off EDGE. You could look around in the disagnostics app for a way to specify the thresholds used, though, and myabe tweak them (the HD7 diag app shows the current setup but doesn't let us change it).

I was facing the same issue with the 3G signal. Check my post below for solution. Works for my HTC 7 Pro not sure about LG Devices.

One more trick I would like to share is to create a contact with the name as 3G and the phone no as ##3282# and pit it to the start so that when u restart the phone u have easy access to the menu access to the menu.

Are these settings you mentioned reset to default after rebooting the phone?

Yes the settings reset after a reboot. So need to apply them after reboot.

Anyway to force 3g over edge?

My Fuze is always connected via EDGE, even though I live in a 3G serviced area (San Francisco Bay Area). I'm assuming the phone is choosing the stronger of the two signals by default, which is fine for voice, but EDGE is excruciatingly slow for streaming video. Is there a way to force the phone to use the 3G connection?
I dont know about the Fuze but on the european Touch Pro, all you have to do is
Start --> Settings--> "Phone" Icon -->"Band" Tab
Here you can choose your netwok type, by default it is set to auto, but you can force CDMA only if you want.

Thank you for the help, but unfortunately there is no "Band" tab under Start --> Settings --> Phone on my Fuze.
Install the Advanced Config utility (you can find it pretty easily if you search the forums). Using this you should be able to restore the phone app's band page. This is a common way carriers prevent you from messing with settings they don't want you to. You're actually lucky, there are more tricky things to fix than this one .
I got my Fuze today and was wondering this exact question about the 3g network and your fix worked!
Thank you

What setting was changed to get this effect? Sorry ultimate PPC newb.
Once you install and have Advanced Config up and running you go to Phone tab, click on it and it opens a new tree if items for you to click on, scroll down some til you find "Show Band Page" click on it and then change it from "No (default)" to Yes. Click the left soft key that says "Done" and then it will ask you to restart your phone, click yes on that message and once its back up and running you should have access to the band tab in settings for the Phone.
If you have any other questions post here and I'll try to help out.

Is there an answer to this question or not? How do I force 3G? There are 3 to choose from. 2 of them disable data connection. The other doesn't force 3G. I must be doing something wrong.

[Q] MIUI without data?

Hey everyone
i'm pretty new to the whole nexus s scene, as i've had this device for about a week now. I've rooted my phone successfully and i'm running MIUI's latest ROM..1.8.5 i believe. Now for the problem..
For some odd reason I'm unable to connect to my 3G network at all (yes, data is enabled in the settings, and set to 3g prefered/2g/only 3g..still nothing). Usually there'd be that green "3G" on top bar of my screen, but it doesn't show up. Now i rely on wifi to go online, which isnt a problem...but it feels like my money's being cheated if i dont use my data in occasional situations. I've tried flashing it again and again, but no results. I've flashed my phone to the Oxygen ROM, and the little 3G icon appeared, indicating that data is enabled (i forgot to actually check if it worked LOL). I haven't found anyone else experiencing this problem with MIUI, but i've found threads on them having some sort of difficulty with their data. If anyone could help me out, or direct me to a thread that has a possible solution, i would really appreciate it ~ thank you in advance.
Also, I'm on Fido.....if that helps.
I'm on the latest miui and I don't have that issue try toggling the airline mode to see if it will kick it in. If not really download the Tom and do a clean install see if that works.
Sent from my Nexus S 4G using XDA Premium App
hey, i've tried toggling the airline and it doesn't help. also, what do you mean by "the Tom"?
What happens when you try to connect with just 3G (what type of error do you receive)? Miui's stock 3G icon is white
Also, I think the other gentleman meant to spell ROM

He meant rom, auto correct changes the word rom, I think you need to wipe and reflash the rom.
hey, i've just tried reflashing the rom...and still no 3g ): !
also, when i enable data, and set it to 3g..there's no error. there's simply no "3g" icon on the top, and i can't connect.
Did u try manually inputting your apn? Sometimes providers don't push the settings to you
what exactly would i put in for my apn? sorry, total noob here :/
Go to menu>settings>system>mobile network setting>access point names. Do u have an entry there? You should. If not, you need to check with your network provider for the settings.
i've just tried putting in the APN settings (copied the stuff from the APN settings when 3g works on the oxygen ROM). is there anything else i havent filled in and should? cuz....it still doesnt work
Not really. Create it, fill it, save it, choose it and restart. Should work, it always did for me
How's the battery life on that rom
Seems ok to me. 3g uses alot of juice since the service is crappy in my country. Otherwise, best rom I tried
dang :/ still nothing... i've noticed something though. when im on my oxygen rom and search for networks..the option "Fido" pops up. when im on MIUI, the option "Rogers Wierless" pops up in the place of "Fido" .___." that may have something to do with it...
Same problem here on desire s.
When I try to change the apn setting I get a force close.

issues connecting to work WiFi

Hey All
since upgrading to CROM-i v5 i have been having some issues with connecting to me work WiFi, i never had any issues before v5 but this seems like the only place that has issues. We use Cisco access points that run through out network and we are currently using 802.1xEAP authentication. All devices need to authenticate via MAC's which i have passed onto so they can add it in but when i enter in my details it just stays at "Connecting..." and just hangs there and never ever connects.
i use the tablet at home and it connects with no issues.
Anyone have any ideas???

So baggs, should I, a US user who is on 5.03, install WW version to try and make mine stop dropping connections after sleeping? I'm also having a hard time connecting to my ATT wireless router. And other places that I used to be connectable with before I got my 20x Dock. I love the dock but need wireless connectivity. I wanna watch movies in bed, err before sleepie time anyways.

It shouldn't drop a connection whatever version you are using. Can you capture a logcat from when you wake? Does the WiFi icon turn grey or stay blue....?

I keep trying to log into the network at home and on job sites but the wireless utility never seems to accept my passwords. I can't get a signal reading, which is bollocks as I see high signal strength from the access point in the wireless AP list. I will install logcat and capture some logs later.
I dont recall the wireless being this heniky before the newest ROM. :crying: Oh and sorry bought the bags, I see after more careful reading its "dags"!
seems to me that im not the only with this new wifi connection problemj hmmm i still havent been able to connect on my home wifi even with a reformat, factory reset and fresh install of the newest cromi 5.0.4

This may be mute, going to try flashing 5.04 and see if that makes a difference. But per your request Im attaching both startup and sleep recover logs. Hope it helps. I have no network connectivity at this point!
Edit0: I did the update and at first network didn't connect. So I "forgot" and then reselected my network and now I am connected and am getting email, updates from apps, and other goodies. Will try sleep and recovery to see if that works too. Just hope it works going forward so I can watch some movies and family guy episodes when trying to go to sleep. I'm happier for now at least. If this fails I will go back to 5.02.......

hey sbdags
sorry for the late reply just got back from overseas holiday and 2nd day back at work.
i reflashed using WW and still have the same issue. i think it might be y works WiFi they must have changed something and cant connect now. might have to get them to recheck that my MAC is still in the allowed group but just so weird that it stopped working.
will have to confirm what channel they are using and get back to ya. It does find the connection but when ever it tries to connect it just sits on "Connecting..." and just times out.

Just confirmed with our network guys here we dont have a specific channel set for wireless devices, they have set it to auto-select so it will choose the least congested channel and try and connect. They also auto-adjust down/up their power so they dont overlap with other points of the same network.
Dont know if that will mean much to ya sbdags. But i might try and dig up the older versions and see which version it started happening.
you recommend doing a wipe and then flashing? or is it fine to start from 5.0 and dirty flash the way up till it stops? also you recommend using a specific kernel? i have been using _that's kernel from version 5.

5.0 and dirty flash up should be fine. Also stay on that 4 as that is a stable kernel until you can determine if there is a problem.

hmmmmmm just tried what you suggested @lj50036 actually got a little further than before, attempts to connect and does for a 1 second and then drops out and turns my WiFi off and then back on, and attempts to connect again and does for 1sec and then sits at Connecting... again and just keeps cycling around like that...
i was able to get a guest account and that connects no problems, but the way that i am trying right now actually authenticates through my domain account and allows me access to my works environment
thanks for the input guys much appreciated... i guess its just a lost cause.

"Set preferred network type" defaulting to GSM only after a reboot

I recently tried to fix my GPS issues by trying out some previous OPO modem files, I ended up just reflashing the 33R one though as none helped. I now have a more annoying issue since doing this.
My network, Three UK uses LTE/WCDMA, so in the *#*#4636#*#* menu it is best to set "Set preferred network type:" to LTE/WCDMA, but after a reboot this changes to GSM every time, resulting in no signal at all.
I did some googling and found that some people had been able to edit their build.prop to change this default value, I changed the values as seen in the attached image. Unfortunately after a reboot it now only changes to WCDMA only and not LTE/WCDMA only. Does anyone know what changes I would have to make to make it change to LTE/WCDMA only?
Thanks.
If someone could upload their default build.prop that would also be useful.

Three has no 2G network at all, 3G/H+/LTE only. With it set to "GSM only" I have no signal at all.
I just need to set it to WCDMA/LTE and it works perfectly. The default config (after a reboot) that came with the phone works great too but it's changed to GSM only after flashing modems.
I've just flashed stock system.img, boot.img and modem using fastboot from the 33R fastboot zip but it's still not working as I'd like.

this works but requires root, it works for dual sim as well, the settings will "stick" (save and apply) after a reboot. and PLEASE NOTE that of course you change the "3" to your preferred network

[urgent] I broke my signal band mode

So I went into *#*#4636#*#* and I putted my phone in my pocket with screen on.
I took it out of my pocket and I saw set bandmode 23 successful.
No my question is, how can I revert this.
I've tried every different bandmode there is to select
Euro: gives me Edge connection and I can call
Bandmode 43. Gives me 4g but I can't call.
Not in the *#*#4636#*#* menu but in something else
I know about the engineering mode and I know how to enter it too. There is an option bandmode and bandmode2 both with over 100 different modes
Setting it to auto from this even more secret menu still didn't work.
To get in this mode download shortcut manager from gp.
Open app tap 3 dots and click app explorer.
Scroll down to com.oneplus.factorymode tap it
In there you will find bandmode and bandmode2
Any fix? I've tried every possible fix.
I'd like to call and use mobile data.
I would contact oneplus support if I were you
Move your sim into the other slot if it's not occupied, otherwise I found this method. I have not tried it yet, though.

Ya, don't go playing with the band selection, or you may just get dropped to 2g connection with no LTE possible.
After digging around, I found a fix to get LTE back.
Download the "Network Signal Guru" app from the Play Store.
I told it to "Clear Forcings" in the menu, and LTE is back up.
