[Q] Wi-Fi 802.11n doesn't work with a Russian sim card, is there a fix?

Hello. I've poked, googled and searched around trying to find a way to fix this annoying issue.
Long story short: till 2004-2005 Wi-Fi N bands weren't legalized for civilian use in Russia. Now they are and we here still sometimes receive such devices which block usage of those bands. I've faced the same idiocy with Xperia S.
GB worked with channels 1-11 of Wi-Fi N (yet 12-13 should have been available too since Russia != US). Still it was bearable. ICS was the same (I've inquired about this issue a couple of times on the official forum to no avail).
Here the long-awaited JB update comes up (hooray) and bam - Wi-Fi N is blocked. Now if I pull out the sim card and turn on my phone - it will successfully connect to Wi-Fi N network. If I put it in and reboot the phone - the phone will connect to the N network for the first few seconds and then - as soon as it initializes the sim card - it will drop the connection. If I don't enable 'G/N mixed mode' on my home router, it will be sitting with no connection and showing me that N network but it would not connect to it.
Now as I told before I've been searching around internetz and was able to find some lose ends and few possible fixes to this issue.
1. Region code change. Doesn't work. It did before when the phone wasn't able to connect to channels 12-13. But now when N doesn't work at all this fix doesn't help. It looks like the problem lies deeper now.
2. Messing with wpa_supplicant. Works... sorta. I've replaced stock wpa_supplicant file with this one: http://forum.xda-developers.com/showthread.php?t=2399391 . It kinda works after that but starts acting up further down the line. E.g. it connects to a N network and everything's cool and dandy BUT when I leave my home and wake up the phone somewhere else I see that it still thinks it's being connected to my home network. It sees the other networks around it at the moment but it doesn't want to choose them as it kinda connected to my home one. Which is nowhere near. And if I get back to my home with the phone in such state - it won't continue to exchange data over my Wi-Fi network. So to fix that I have to turn wi-fi off and then on again but I don't like such a behavior since in my town there are a lot of free wi-fi hot spots around (in public transport, at bus stations, in cafes, etc) and I'd like my phone to choose and connect to open hot spots automatically.
So could someone please shed some light on how all this restricting thing works, what mechanism is responsible for available Wi-Fi modes except region code field in the databases and how do I fix that? (or break it?). I mean the second fix is almost works but it looks like wpa_supplicant wasn't hacked properly. Maybe there are other wpa_supplicant files available?
Thank you!
Edit: forgot to mention that I'm talking here about Xperia S, firmware versions are: JB .200, .211, .96

The same problem with my xperia ION from Syria , i try many APPS to change region code but no luck , and then change wpa_supplicant file but i face same your problem and i am suffering of about this problem , and i already change my rom from 211 to 96 and the problem still .

Yea, I saw few people here from Syria and from some other African countries also and they all had similar problem. Although I didn't know anything about legal status of Wi-Fi N bands in Syria so I've decided to create a new topic.
It looks like this problem is quite wide-spread and before Sony officially acknowledges it, I hope we'll get some help from devs around here. I wonder if the devs actually look through troubleshooting branch of forum. Something tells me they don't.
I mean if there are fixes available it shouldn't be too hard to modify something in the system to get that damn thing working. This wpa_supplicant fix is especially interesting but I can't find any tutorial on how to edit it. Google keeps silence.

Did you find any solution for this problem , because I try many article but no luck .

No man, still nothing. I've put my hopes on Sony, thought they will update. Looks like I was wrong

[Q] How to connect to hidden WiFi?

Hello xda community!
I have a strange and serious problem: I can't connect to hidden WiFi's.
I'm with a LG G3 D855 10H (no newer versions available).
At work we use a hidden WiFi without password but with Juniper VPN.
When I type in the network name and save it, it tries one time to connect, then my LG G3 shows "not in range". After a few seconds, the WiFi is on the top again with a very good signal.
When I try to connect again, it shows "not in range" again and so on.
I tried it at home and created a hidden network and it was reproducible.
Anyone else has problem with this?
Many thanks in advance for your help!
Best regards,
Jake

Now that is what you call a 'special' post!
Would you care to explain how it was resolved for the people that have the problem.

My problem still exists, but isn't urgent anymore.
I found out, Android itself have problems (or restrictions?) to hidden WiFi networks.
I also found an app names HiddenSSID Enabler, but it seems it didn't work for me (or G3?).
If someone has a solution it still would be very helpful fo rme and the rest of the community.

I have logs posted in my first post, WIFI DESTROYED TWICE or there abouts.
I've had to resort to DATA and its killing me haha i think i am getting close to fixing it, well i think i may be closer than you two and can one of you kindly take the lead as im reinstalling windows and i haven't gamed in 6 days :|
/system/etc/wifi/WCNSS_qcomcfg.ini
then the problem is complex but i am sure it is something to do with gEnableApProt=1
Offshoot fix, reinstall using googled imei number that doesn't have a flag or some how fix the flag <READ A FEW DAYS BACK>
I think actually the program that stuffed me was Airmon by maxters. It asked me if i was pro and of course, i said yes. Who would simply click no? I know a ninj wouldn't click no. I think there is a manual reinstall to link to it again i find the modem in its own partition having a chill, most likely trojan/backdoor and pwning everything around me.. I had three encrypted vpn backdoors and escalated accounts on my computer I paid the 5$ for the binarys, i think i paid 5$ for the back doors.
Not to sell Airmon out though.. Rooting our phones and accessing countless forums and websites really does leave us rather "xposed" some other cuplrits may be dsploit, ROM manager, linux Deploy/kali, Pamn IP scanner, system app remover pro, busybox pro's (Stephen/JRummy) or CMinstall/accessing the forums and trying to install cynagenmod / twrp recovery. I'm probably going to go with..... Airmon/Linuxdeploy or uninstalltool. But may have just been my IP logged and i hit a booby trap script along the way.
You guys done anything of the sort?

Neither I understand what you are talking about, nor am I (as not native english speaker) good at "sentence guessing".
I have a rooted phone - of course.
But I'm pretty sure my WiFi is not destroyed...

Connects to Guest Networks

Hello,
I have a Samsung Galaxy Note 2, SGH-M317i (Bell Mobility) and recently installed Cyanogenmod 12.1 (Lollipop 5.1.1). All is running well, the device actually seems to be running much faster...probably due to the lack of bloatware that originally came with it. Sure, I miss some of the "cool" features that the manufacturer had added (ie. hand swipe for screen capture), but overall I am extremely happy with the decision to flash the ROM. Although it does self-identify as a SGH-N7105 now. (About Phone > Device model)
Anyway, I have noticed that when I have my guest networks enabled on my home router (an ASUS RT-N66U running the latest Merlin firmware), my phone insists on connecting to the Guest networks (a2.4 and 5 GHz) instead of my full, "regular" network (hidden SSID, but a "Saved" network in the phone). Even if I go into the WiFi settings and tell the phone to forget those entries, it will still try to connect...even going so far as to say "connected" even though I know it does not have the proper credentials. I have no idea what is causing this as the problem was not present on the stock 4.4.2 KitKat that I had previously.
Sure, I could give it the credentials for those guest networks (all are WPA-Personal protected) but I have restricted those from accessing the intranet as they are primarily for guests who come by, so that is not really a viable option.
Does anyone have any suggestions? It seems strange that it attempts to connect and save these networks, so technically, I shouldn't have to do anything to keep the phone from connecting. However, since it insists, I had thought that Android would have a native (not requiring an app) method of blacklisting these networks. I have looked at apps such as WiFi Ruler, but again would've thought that there is a manual way of doing this. (I don't know if this is obvious by virtue of the fact that I am running a custom ROM, but the phone is rooted.)
Thanks!

used this code and off your wifi power saving mode and try *#0011# select wifi..u may need need press the botom left button to select wifi

Very odd. It seems that since installing CM12.1, my device no longer accepts or recognizes USSD codes. I guess I hadn't noticed since I had rooted and unlocked it prior to flashing Cyanogenmod over the stock ROM. I did some reading and I found that there is a patch to enable those codes (and SMS) on CDMA models of the Note 2. However, mine is LTE and does SMS, MMS, and it uses LTE without issue.
Here is a link to that page:
http://forum.cyanogenmod.org/topic/112400-solution-to-sms-and-ussd-code-on-cm121-cm12-cm11-cm10/
Is this something anyone else has experienced? Should I follow the instructions on that page and install the patch?
Again, my phone is a Samsung Galaxy Note 2, SGH-i317M but since the installation of CM12.1 the About Phone > Device model reports it as being a GT-N7105 with a Baseband Version I317MVLUDNH2.
I'd really like to try the solution to my WiFi problem, so if anyone else has had experience with the USSD codes not working please let me know if there is a solution.
Thanks!

To update my last post:
Some USSD codes do work, I watched the pop ups more closely this time and there is one before the "...invalid MMI code" that says "USSD code running". The main one that find interesting no longer works is the one I had used to unlock my phone *#197328640#. I had figured that it would not have disappeared simply by installing Cyanogenmod. Further, I also followed that thread I had posted the link to a little further, and I'm not comfortable flashing the "patch" it leads to as I cannot confirm it's original source and it does sound like it may be another full ROM.

Galaxy Tab Pro 8,4'' [SM-T320] - WLAN flapping issue

Hey guys,
FIrst of all: Thanks for maybe helping me.
So my problem is that I have a really annoying WiFi issue with my Galaxy Tab Pro. I installed a cm13 build (Link in that style because I am not allowed to share links...)
Code:
download[B]DOT[/B]cyanogenmod[B]DOT[/B]org/?device=mondrianwifi
a month ago and have one big problem with it. Whenever I want to use WLAN to connect to the internet (or use it on my local network, whatever) it just keeps flapping. It turns on and off and on and off and so on. I thought that it would be related to my home network at first (so that it doesn't get a IP or something like that), but after I checked my DHCP and general network settings and came to the conclusion that it can't be related to that. All other devices in my network are able to get a IP (and go online). When I turn on the WiFi on the tablet and check the network settings I see that it gets a IP but looses it after 1-2 secs. The thing which makes absolute no sense to me is that after a while (turning WiFi off and on again, 3-4 times) it often is able to get and keep a IP address. After that everything works fine - often for 1-2 hours until it looses the IP again and I have to begin with the game of randomness. I checked in the known bugs and could not finde that issue listet there. So I think it is maybe not related to the cm13 build I am using..? Or not even to the device? I don't know. Maybe you can help me - would be helpful enough if someone could tell me which logs I have to check when having a WiFi issue. I am quite new to such problems and don't know how I should start the troubleshooting.
So thanks in advance and greetings,
Maik

set the mac adress

hello,
since the update to open 8 i have the following annoying message often at my phone
"Please set the mac adress"
but i havent change it, i cant change it and in the settings there is the mac adress for my phone
i havent make a update to an unofficial software and i dont have to try change my mac. the message or failure was after the update on the phone
reset the network settings doesnt help and restart helps only for a short period of time
my phone is the 3t and firmware is the newest open10. and the message is since the last updates fixed in my phone
i would be thankful for any help of an expert on the xda dev
best regards

Do you get the message when the phone is trying to "wifi" connect to a specific router? If so it may be worth looking at the router's settings for the phone, deleting them and trying to connect from scratch.
