universal and wifi

hi everybody! finally i got this wonderful mobile phone! i'm just disappointed by the fact i can't connect to any wireless network... not even mine, which is proprly configured... i can obtain the list of all the networks, i see if they are free, if they are encrypted and so on, but when i try to connect to mine or the free ones appears "connecting..." and then it skips this connection and try with the following one... how comes it does so? i tried with different versions of OSs but it's always the same issue... i also disassembled it and everything is it its place... can anyone help me please? thanks

Welcome to forums
Yes, you have one of the best devices ever made!
Try a hard reset or reflash another ROM

Good luck,

already tried, but nothing... i tried to use the tomal one, the italian one and the chinese one... but it's not working... do u have any idea why? in my opinion the hardware it's fine, as long as it can see the networks the wifi is working. but the software is not responsible because i tried 3 different roms and it's always the same... i really can't imagine where could be the cause...

Try to do A doc format

what do you mean?
EDIT: now i read about it, i already did it and i'm flashing right now!
EDIT 2: No, it's not working... always showing "connecting" but then just goes back to "available" status for the network, it just does not work...

OK one thing you should notice is Universal is only capable b class of wireless so.. and see what class of wifi modem you have and try to install following cab (which i got from Jonny) it should make it capable of wifi b and g and see if problem still presists try another wifi modem and still same then i suspect it might be hardware issue....

also, isn't the radio responsible for wifi connection? perhaps try a different radio?

mine is b/g both active... i'll try that rajivshahi!
@jonny: i both tried .18 and .15... should i try the previous ones?
EDIT: I tried installing that .cab, but it's not working... do i have to do something in particular after installing it? what do you mean by hardware issue? what could be wrong with it if i see the networks?

the cab just creates a some registry. so try to connect to other modem and see... if everything fail then it might be issue with uni's hardware... as if it was software issue flashing to another rom and another radio should fix it...

just a quick question.... does it connect to a open network or is it just the encrypted oneş.... i cant connect to any other than a WEP network...???

Try this (Configure Wireless Network, DON'T activate "This is a hidden network")

Maybe this will help:
In my case, after a hardreset, I cannot connect to a Wi-Fi Network until I do the following.
1.Turn on Wi-Fi--> when your network shows up, enter the Network key and hit "Connect". (Here is, where the device tries to connect, but does not! IS THIS YOUR CASE?)
2.Go to Wi-Fi-settings (through the Communications-Manager) --> push and hold your finger on your network to open the context menu --> select "edit".
3.At the "Configure Wireless Network" page make sure the check for "This is a hidden network" is NOT set! --> Hit "Next".
4.At the "Configure Network Authentication" choose for Authentication "WPA-PSK" and for Data Encryption: "TKIP". (Make sure the Network key is entered.) Hit "Next" and then "Finish."
Again your device will try connecting and (hopefully ) be successful!
Cheers,
mdajj

HTC-Universal
ROM: Tomal v10 WM6.5 Build 5.2.21872 (http://forum.xda-developers.com/showthread.php?t=573739)
RAM: 64MB
Radio: 1.18

Welcome aboard
Thanks for that tip, hope can solve the issues some members reported

the point is that i can't connect to open networks... now i don't have any encrypted networks i can access... and i tried to set the networks as not hidden, bit it's not working... mdajj got exactly what happens to me "hit "Connect": here is, where the device tries to connect, but does not!" and it shows directly "unavailable status for the network, while the router is on the same desk i am sitting in front of. T_T
now i start thinking that the uni can connect only to encrypted netwoks... how could it be? i bought it because of the opposite reason...

Wifi cannot connect if signal is too low.
Unmount the device, check the wifi/antenna connection and make sure that it is not getting touched with other assembly...

i already did it, and i checked again today, the antenna is fine it does not touch anything and its shape is perfect... BUT today i noticed something missing, i have no idea why i never noticed before... the conductive tapes are missing, but even if they were in place, they'd not touch the antenna, so i guess it's not a problem... am i right?

wifi connection problems
Can I suggest a non technical approach. I also had a lot of problems with wifi a couple of years ago, it turned out to be the BATTERY I had a noname battery from Hong Kong that I think just wasn't generating enough power. The phone and everything seemed to work fine except for wifi. When I replaced the battery wifi suddenly worked perfectly. If you know anyone else with a Uni that works on wifi swap the battery and give it a try.

i also thought about that, but even when the power supply is connected to the phone wifi does not work... and then i have 2 batteries, one is not original, Yaobao brand, and the other one seems to be original, but with both does not work... [both 1620mAh]

Thinking about this, I don't know whether this is relavent, or simply an earth... but the original battery has metal case (or partially), which has a contact pressed to it when inserted in Uni. I have replacement batteries with solely plastic cases, so the contact isn't made. This doesn't affect my wifi, but it's just a thought.

yea, u r right, i did not noticed before... i have both kind of batteries, with one it makes contact, with the other it doesn't... and it's still not working! by the way thanks for the help!

Blow some hot air around the board (if you have a hot-air-station). This is the last thing you can try.

[Q] SM-G900L Phone unable to use 4G in Australia?

As the the title suggests,
My dad's boss purchased this phone and while it works with any sim you place in it, upon turning the phone on, it basically summarises the following,
You have inserted a USIM that is not part of LG U+, and as such will be data locked.
(not word for word quote)
Now I take this to mean that the phone was carrier locked to Koreas LG U+, but the phone works here, and phone calls, and 3g speeds, but no 4G/LTE.
The current firmware version on it is 4.4.2 with I believe G900LKLU1AND3_G900LLUC1AND3_LUC
Now I've tried many different things to try and fix this;
I've read that 4.3+ version is bootlocked, (not exactly sure what this changes)'
I've tried flashing an Australian SM-G900I firmware (thinking the bands will be fixed, as its a software not hardware issue as far as I can tell)
Upon trying this, Odin throws a failed error, the download mode on the phone freezes, I can reboot it, and it's all good and dandy.
I then looked around and found that its possible to put in a SIM unlock code, however I query how that would work as the sim already works, just not LTE/4G
I tried Chainfires Region Unlocker (yes I know it said only tested on Note 3), which said succeeded, but actually did not enable 4G.
And I also saw a rumour that, if you place a phone call for 5+ minutes it will unlock said phone restrictions. In the phone logs it does show a phone call occurred previously before this phone was purchased, not sure if it was 5 minutes, but this may have been the case.
I'm stumped as to what can be done to flash this phone (or whatever can be done) in order to force it to allow the LTE/4G Networks,
Just to re-cap for the tl;dr,
4G/LTE not connecting as the phone mentions it restricts it due to being a NON-LG U+ SIM upon turning the phone on.
Please help ?

Hi
I also have g900L and had issue with LTE at the beginning But I resolved the issue by the following;
Please dial 319712358 and they will show you a box where you need to enter password then enter 0821.
This will lead you to the hidden menu page where you can find network mode where you can switch it to 4g mode.

I will pass this info on to the guy that owns this phone (my dad's boss) and hopefully all good,
Thanks man ,
Will post back here once I find out if it works on his phone.

Hi, just wanted to let people know I've had this same issue. Bought a G900L online and the network would connect to Optus' 4G/LTE for a few minutes at start up then will automatically go back to 3g. The solution above seems to have allowed my phone to lock to the 4g network.
Thanks

[Q] Nexus 5 will not automatically connect to cell network

Hi All,
I've been having an issue after upgrading from a Nexus 4 to Nexus 5 where the phone will not re-connect to the home network (or will only reconnect to GSM with no data) after losing connection. This happens for example when going into an elevator or parking garage; I'll lose signal and when I get back into a signal area it won't reconnect unless I go to the "Mobile networks" -> "Network operators" menu and select "HOME" or "Automatic Registration". I'm using Straight Talk wireless with an older T-Mobile SIM (before they switched to only AT&T). I've called Straight Talk a few times to try and debug this, but the only instruction they've given me is to reset the APN and set it up again, which I've done a couple times to no avail. They claim that the SIM card is good on their end. Any ideas what might be causing this?
Thanks!

It sounds like the Baseband/RIL problems I had with my old LG OP2X with non-stock roms. For me, it was fixed switching to aeroplane mode and back, it could also get stuck there, I remember it once took me half a day to get it out for I didn't want it to wipe it.
Any way, may be it's not the same but it could be fixed flashing a baseband, I think I saw a thread about it somewhere around... Also, flashing the full firmware should —if it's not a hardware issue— solve the problem without doing much research.

HI

Hi Were you able to get a solution for this, My nexus 5 does not connect automatically to the network, it works only for manual search.
Please help...

Same problem here. Any solution?
I'm stuck with out any connection for the las two days. Tried removing battery, airplane mode. manual search. nothing.
Tried my line in other phone and it worked, other line in my phone and it didn't.
S4 I9500. Paranoid 4 Beta 4.

I don't have a really good solution, i reflashed my phone to stock and it did not fix the issue. I ended up switching carriers to T-mobile and haven't seen the problem since. It seems it was a SIM or network problem like i suspected

Can't get connection to ANY carrier

Hi! I'm having some mayor problems with my OnePlus One.
For some time I have had problems getting calls and sms when using 4G but it seemed to be a problem with my carrier but 2 weeks ago I dropped my phone and the screen broke so I bought a new screen and replaced it. After that the connection to my carrier dropped randomly and now after trying to fix it in different ways I can't get any connection at all with any carrier !
What I have tried so far:
Factory reset
Reinstalled CM
Put paper under the sim for tighter fit
Turned the radio off and on and restart phone
Change pin code
Replace sim-card
Tried different carriers on my phone (my simcard worked on other phones so it is the OPO that is the problem)
Total restore by fastboot-flashing
Installed OxigenOS 2
Tried all modems from the modem collection on CM and Oxigen.
Retyped the APN by hand
Opened the phone again and checked that all cables are connected well
Tried manualy connect to my carrier under Network Operators
For a short time of maximum 10 seconds I got a 4G connection twice in now 3 days of trying but then it stops working again. It feels like a hardware problem BUT I can see a lot of different carriers under Network Operators but when trying to connect it loads for ever and then says "Can't register to your carrier". I called my carrier and thay said nothing was wrong from their end and when I tried on other phones it worked flawlessly.
I'm really out of ideas now and I don't know where to go from here. I really hope someone of you knows that might be the problem!
Thank you so much!

If imei present you can try mobile phone exchange offer on flip kart like online stores. When this happened to my phone I did it , very easy.

Sometimes opo dont search available network or wont register on any network.
Sulution: go to access point and reset it to default first then go to network and try to search for network n if ur able to search then try ro register manually and if it does not work then go to dialer and dial *#*#4636#*#* then click phone info and select the lte/gsm ato prl mode and then click turn radio off and again tuen it onn then smsc refresh and update ( i dnt remember it correctly) if that dnt help then ur network antena is damaged

D6683 - Upgrade to D6633 Marshmallow Firmware - LTE Connection

Hi guys.
Just trying to share my observation and explore if we can do anything.
I am using D6683 (I think it is support to be a HK based handset). Using Lollipop, it has been working perfectly but 16GB not enough hence MM function that allow SD card and Internal memory merge is appreciated.
Since Sony decide to ditch us using D6683, the only option is using D6633.
1. Try using MM .575, it has huge connection problem. The phone will just stay in GPRS mode even connected to a LTE network. Driving from one point to another point, will just cause it to data connection to hang. Putting it in airplane mode and anything else won't work. Only reboot works
2. Restore stock and upgrade to .291, first day testing seem to be ok. Got LTE connection. It did try to swing a bit but it has been maintaining well. This i started driving with Waze. Connection start to go haywire, but it will be still try to reconnect. Data are "maintained" to certain extend. Let the phone along for about 2 days, the next thing I realize, only GPRS left. The signal logo got no more H, H+ or LTE. Check the phone service menu and all info confirm the LTE is available. Again a reboot fix the problem.
3. Change the setting to only WCDMA + GPRS. The phone was "perfect". No data hang issue and etc
Need all the sifu help. Assuming if the phone is rooted, how is the phone determine the connection method? I presume that the phone will initialize the modem to dial the connection. Can anyone share anything that we can probably trigger a redial and probably eventually inject into the phone data connection sequence. Again using Lollipop, there is no issue.
Appreciate any comments/advice.
Regards
Dan
