I have the following situation:
I live in Cuba, and my phone is operating on CUBACEL, the Cuban celphone company. This is a 2G network. While it has CUBACEL sim inside and the Wifi interface is active, it seems to stop working. At least within the 2.4 Ghz band. It simply does not detect any network whatsoever.
If I insert other micro-sims, like one from AT&T USA (3G), the phone wifi starts working, and it detects all networks. Another curious thing is that it will not detect any network if it does not have any sim inserted.
Does anybody out there have any idea of what might be the cause of this behavior and how could it be fixed?
Best regards to all,
Zedd.

Hi Zedd,
I've been struggling with this for a while now and today I finally found the solution. What happens is that Cubacel has the wrong country code on the SIM cards. What you have to do is change this on the phone. You can easily get this fixed following this great tutorial:
http://forum.xda-developers.com/showthread.php?p=21406675
After installing this app and removing the power saving mode it worked like a charm for me.
To remove power saving mode dial *#0011# and then in advanced choose Wifi. There turn of Power Save.
Hope this helped!
Best wishes.

I had the issues with my phone (bought outright from Bell, unlocked for use with Rogers)
To connect to Wifi, try the following, and report back:
1) Disconnect the WiFi entirely (as in un-check the on button)
2) Turn WiFi back on
3) When your WiFi hotspot becomes available, instead of just tapping to connect, TAP AND HOLD the name of your hotspot, and a prompt will appear asking you to connect or forget the network.
4) Click "Forget network"
5) Toggle WiFi on and off one more time
6) Once your hotspot is found, TAP AND HOLD until a prompt comes up asking you to connect.
Press connect, and voila, your wifi should be working like a charm.
My situation:
1) Bell Atrix (Build OLYLA_U4_0.37.4, Android 2.2.1 obvs)
2) Linksys WRT150N Router 2.4GHz using WPA2 Personal passcode
3) Unlocked + working on Rogers with cell unlock code.
interesting, i think i tried that with my att atrix (both stock and the leaked firmware) already, and it didnt produce any useful results. ill retry it later today, and post the new results.
I wonder why it worked for me. It can't be an issue with sims blocking access personally I think it is the router frequency causing issues.

I don't have any wifi issues with my unlocked Bell Atrix on Rogers. I'm using a different router though, and I also did a factory reset before power cycling and unlocking my Atrix. The Atrix also provisioned the APN settings when I unlocked the phone with my Rogers SIM in it.
It doesn't get any easier than that.
heh lucky you. well judging from the dmesg i did with wifi working and wifi not working, basically the only difference is
Code:
Link Down
Invalid ioctl data=-22
wl_iw_set_wap Invalid ioctl data=-22
Set ISCAN for wl_iw_iscan failed with -22
so im pretty sure there has to come some command from the sim/carrier that issues the -22 "command" , which than fails everything
oh and hoesntrix, i just remembered one more thing, namely:
after inserting the sim, the WiFi manager where i would have to do your steps, doesnt find any networks, or in fact it finds networks for like 1 second and than they disappear. and it cant be a router frequency issue if it works without sim after a factory restore...
im thinking some file gets changed in the /data directory/partition that gets restored with a factory wipe. since if you change things in the /system directory/partition they stay changed even after the factory restore.
my wifi was working until i restored parameters with Titanium backup from my Defy....
perhaps nothing to do with the other problem but who knows....
That would make sense. I really wish moto would not lock down the boot loader im just glad my wifi is working

Hi,
This might be specific to my provider(Airtel) or city (Bangalore, India) so please excuse me for sending to such a wide audience. But I hope its specific to phone and there is a solution.
I keep loosing my 3g connectivity on this phone. It comes and goes and has now basically become a reliability issue. Most of the times I need to deactivate the data network mode and activate it back.
Has anyone else also noticed this?
It's because where you live 3G service is unstable, same with me also, it goes back to H+.
Regards.
or maybe you should try and change your modem.
try flashing KH1 or KH3, see if it matters..
Thanks for the responses. If its related to network, I guess I don't have a choice. About flashing the ROM, I have not yet rooted the phone and lies is still on KF3, so guess I will wait for the next update and hope things will improve.
I had some similar problems here in The Netherlands... I use a provider that is 'roaming' on another provider's network (for those who are familiar: I use Telfort, which roams on the KPN network).
The current CSC I have in my phone, is a specific CSC for The Netherlands (XENKE1). However, it keeps losing 3G connectivity over time, and I also need to reset the connection to get it back working.
For now I can solve this issue by manually selecting the operator instead of automatic operator selection. You might want to try this, it worked for me at least.
Thanks gscjot. Your solution seems to have worked. In last 20 odd hours I had to manually restart the 3g service only once. So I guess this is actually not a issue with the phone itself but the operator. Thanks a lot.
It might have something to do with the modem or CSC that is in the phone. I am currently on stock 2.3.3 but I tried Darky's rom as well (on 2.3.4). As this ROM has a different CSC, I could leave the network detection on automatic. Only setback then, is that the phone shows 'r' (roaming) on my home network and I have to manually disable 3G when I go abroad.
Best regards,
Gerco

Hmm, NL-KPN here with Polish CSC (OXA, don't ask me why, bought it in NL) but I stream internet radio on my way to work in the car for 70 km without losing connection once, and that includes 2 long tunnels.
All stock KG5 with only cf-root.
Still no relief

Hi,
Can anyone on 2.3.4 comment if they see the same issue as mentioned here. I am again back to my struggling ways and starting to believe that is this a software only issue and courtesy SAMSUNG.
Thanks,

Hello,
i have a Xperia Mini Pro SK17i, buyed to Vodafone but i unlocked to use Simyo (Spain).
I have the following problem:
When the phone restart i have data in GPRS or 3G, no problem at this, but in few hours/minutes the internet connection dissapears and the G or 3G icon too but i have signal. I have tested the sim card in other Android Phone and works OK.
All options are the same in the two phones but in Xperia Mini Pro not works. I have not installed any application that controls the data connection.
Any ideas?
uuuuup!!!!!

Finally, i could not solve the problem, I migrated to another carrier and the problem was fixed. I think this phone has any problem with that carrier.
hi. did you tried with any other sim with same network carrier.

Yes, but, as the problem was randomly in the time, sometime works for hours and other time for 2 days, when i test another sim card whit same carrrier, the test was only few minutes.
Try with another sim card of different carrier.

No, none of that.
had the same problem
My gf's phone had the same issue, we eventually had our carrier (Claro- Colombia) replace the SIM card and everything has worked fine since (about a week). Will report if there's any change. She is using stock 2.3.4 ROM and Kernel.
It could be due to unlocked method, but not sure
I will respect to you, if you can respect to the other rest.
Sounds like you may have WAP settings instead of Internet settings. To check this please do the following:
Main menu > Settings > Wireless & Networks > Mobile Networks > Access Point Names >
What you should have here is generally your networks name followed by the work 'Internet" whilst WAP settings are more along the lines of Vodafone Live etc.
To confirm that you have internet and not WAP settings in this location you are best to check directly with your network provider.
I've spend over a month trying to battle the issues with not able to use Live services and Marketplace over the 3G connection.
I've been back and forth with plenty of hard resets adviced by Zune support - no change.
I've been back and forth with plenty of hard resets adviced by WinPhone support - no change.
I've even swapped SIM cards - no help.
Issue:
You can't download apps/music or stream music using 3G. On wifi it works fine.
Reason:
HTC WiFi bug goes deeper than we think. It's not just being or not being able to run 3G and WiFi together or low WiFi signal. But if you at times try and download or ugrade using WiFi and use 2G mode at the same time - you will get this. As soon as you switch from 2g to 3g and switch off wifi - nothing will download off your marketplace.
Solution:
I've reproduced it many many times. However, it will only happen if your SIM doesn't have APN settings on it i.e. non-contract phones using certain pay as you go networks i.e. Tesco, Lyca, Giffgaff, Talktalk
When you go 2g/3g swapping and use wifi - the phone forgets your APN settings. Once you switch to 3g, go to APN settings, edit your password by writing your password again and save it. Restart phone. Now your 3g will work again. You have to do this every time you use combo of wifi/2g or sometimes even when using wifi and then switching to 3g.
Moan:
I've contacted HTC, they don't care, they think it doesn't exist. They want my phone to be sent for repairs. I am not doing it as I have only one phone. I know HTC won't even acknowledge the earlier Wifi bug. But luckily we have workarouns.
Have you tried running the HTC connection setup to see if that resolves the situation in some way?

Yes I did that too. But HTC connection setup settings are forgotten as soon as you swap away from 3g. So everytime I come back to 3g, I have to re-fresh my APNs manually and restart! - such a pain.
thanks....
Hello guys. I recently got my new sim card (4G compatible), but I can't get any signal when I switch to LTE mode. I've read a lot of posts online, tried many things, but no luck so far. I'm in 4G area, tried the sim card on my friends phone and it worked immediately. The LTE (recommended) option is selected in Mobile network settings. Also tried turning Airplane mode on/off, but that didn't help either. I attached a screenshot from the hidden menu.
I hope someone could help me fix this problem. Thanks!
I just solved the problem by flashing newer modem "Modem-D802-30B-EUROPE-OPEN.zip".
