[LG Optimus L9 P760, P765, P768, P769] dhruvbatra205:
The status 7 is not only because of the updater script. Some other files in the Meta Inf folder also contain asserts(my assumption based on some experimentation). Use the Meta Inf folder of CM10.1 for p760 with the MiUi updater script. Just remove the asserts in the script.

P.S. If I am not wrong, you built the patchrom?

[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] lefty_:
In my case the device stopped seeing 5ghz access points after flashing from stock ICS to stock JB signapore rom. Several full wipes and reflashing did not fix the problem.

Flashing the JB eRobot rom fixes the issue. Flashing back to stock JB, and the problem occurs again. I have found no solution yet.

Anyone else?
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] pinsb:
Wipe and reflash achieved nothing unfortunately.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] UpInTheAir:
What did you wipe, and process?

Did you;

1. Flash stock JB

2. Format system

3. Factory reset

4. Wipe cache and dalvik

5. Re-flash JB
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] pinsb:
That's exactly what I did. No 5Ghz.

UK tab, from stock ICS to stock JB.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] UpInTheAir:
What about

6. Factory Reset after 1-5

7. Try another router

8. Ensure router uses/transmit 5 GHz only (disable 2.4 GHz)

9. Temp disable router security and test

10. Save/backup and upgrade router firmware
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] pinsb:
Already tried multiple reset variants and two different manufacturers routers that I know are both working on 5ghz as my SGS2's see them quite happily.

The simple fact is 5ghz is not working using stock JB on my UK tab, even after resets, wipes and pretty much all variants thereof. My guess is that there's a subtle difference between the UK hardware and Singapore variant hardware, could be due to emmision limits and set during manufacture as a hardware jumper or firmware mod (firmware for specific component). 5ghz worked fine on ICS so it's definitely a change issue.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] UpInTheAir:
We know that. We also know it's not SGS2, so don't compare apples and oranges.....

We also know it's more than likely a firmware issue....

Edit: but could be a firmware/router combination issue too (otherwise nobody with P6800 JB 4.1.2 would have it working)....

Did you try the rest of the recommendations 8, 9, 10?

Why not, and report back for the benefit of others?

That would be constructive ;)
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] guho:
Had two 7.7s. After upgrade to jb of both only one had working 5GHz. No amount of wiping helped on the other. Had to restore a nandroid from the working one onto the nonworking one. Successful, with 5GHz reception on both devices. While the root cause remains unknown it is clearly a software issue.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] xaadilhx:
Issues as usual

So we wanted to keep up to date, this is what happens for trying, I flashed my 7.7 (p6800) with firmware P6800DXMD3 vietnam, I never considered 5GHZ networks would stop working on jellybean. I doubt there is a simple fix anyone? I'll just live with 2.4ghz because 5ghz seems to operate similarly when I've tested it.

I did find another posting from mobility.forumsee about the note.

Samsung - Galaxy Note Wifi 5GHz Issue fix for Hong Kong

Galaxy Note GT-N7000 General - xda-developers

" If you have recently upgraded to ICS and cannot connect or see your router's 5GHz SSID, it is because Samsung used Taiwan legal channels for HK as well, You should set your router's 5GHz channle to 56, you will then see and be able to connect to your router's 5GHz channel."

Would that suggest that Vietnam and other Asian countries use different wifi channels, currently on my dual band router for 5ghz, I have 36, 40, 44, 48, I'm not sure but I tried changing the router through all the channels and none of the 5 channels are detected by the 7.7, It shows fine on other devices like the galaxy tab plus, I'm unsure which country was used on that version.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] UpInTheAir:
Sounds plausible/probable.

I suppose that's why it's DXMD3, meant for SE Asia, rather than XX (international).

Know idea idea why Samsung SE Asia would 'restrict' they firmware drivers though...
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] lefty_:
First I thought the issue could be caused by the choice of channels, too. But apps like "Wifi Analyzer" show in my case, that 5ghz is disabled completely on stock JB, not just some channels.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] UpInTheAir:
Logic says that it has to be something to do with the router....

If some have 5 GHz band working, THEN IT MUST WORK with certain routers and channels. Still, the OP has not reported any further testing like I suggested in previous posts, just to rule out any conflict between HIS 2.4/5.0 router bands, security and JB.

Users need to be more specific in their posts; router model, router bands enabled/disabled, security enabled/disabled etc etc.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] lefty_:
I thought the same in the beginning. But at least in my case the issue is independent of any router.

On eRobot JB rom the app Wifi Analyzer gives me the option to scan at 2.4ghz or at 5ghz (and gives proper results in both cases).

On stock JB rom Wifi Analyzer only gives me the option to scan at 2.4ghz. So the app sees hardware that is not capable working on 5ghz at all and does not even give the option to scan at 5ghz.

On first sight it seems to me that it has something to do with the wifi driver. Looks like the wifi chip is not initialized correctly, or that 5ghz capability is disabled at a later point. But I don't know how this all fits together, especially given that for some users 5ghz on stock JB is working flawlessly.

(In this context I find the case of the user with two tab 7.7s interesting. One worked on 5ghz after flashing stock JB, the other one not. Then after simply copying the system from the working one to the other one via nandroid, both worked.)
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] xaadilhx:
I have 3 devices for scanning 5gHz, the jellybean 4.1.2 on the gt-6200 is scanning fine, wifi analyser works on that device & a galaxy phone on the same jb, it's not the router for my situation. Wifi analyser normally changes to 5g networks when you tap the top left below the logo, this doesn't happen on the 7.7 as if the software cannot communicate with 5g networks so I believe as was mentioned it's disabled rather than channel specific.

I can't erase/flash presently, it's too much work & 5ghz isn't worth the trouble. Can the connectivity be flashed alone, I was wondering because you see the firmware version and modem version (which I assume is connections or WiFi settings)?
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] UpInTheAir:
Probably require FULL WIPE.

Most claim they are, but in fact probably not doing it correctly.......

Format SYSTEM in CWM recovery (along with, factory reset, cache and dalvik) would do this, and ensure nice clean flash.

Restoring a (copied) nandroid also formats the relevant partitions immediately prior to restoration.

Wow, when did we take a vote and make you thread king?

Seriously though, when I read this it really got my back up as it came across as quite supercilious, I'm hope that wasn't your intent but that's the way it reads.

I run various routers for various testing situations, and I'm in an environment where my SGS2's can see 6 active 5Ghz and about 30 active 2.4Ghz nets without any problems. Trust me when I tell you this is not a router/encryption/2.4Ghz interference issue, the tablet is not seeing 5Ghz at all under JB whereas it saw it without issue under ICS, as mentioned later in this thread it's not even turning 5Ghz on as WiFi Analyzer is not giving me the 5Ghz scan option (no matter which channel options I select).

The point of this thread is to collect information from as many users as possible regarding whether their setup is or isn't working and what their exact setup is, at the end of the day it's the diff methodology here that will identify the problem and a sample base of 1 or 2 is just too small.

So could all other members who have stock JB only (I realise that certain members state that the robot version is working OK but let's stick to stock at the moment for data collection purposes) please state if their 5Ghz is working or not, where their 7.7 originated (for example mine is a UK unit - and it was not a foreign import so if you're not certain where it originated please state that and I'm sure we can help you ID it) and what they had on the machine prior to stock JB (i.e. stock ICS, some other custom ROM) and finally what wipes and/or resets they did when they applied the stock JB firmware.

Thanks in advance.

Hey, thread king here :p

By dismissing suggestions that you haven't even tried or reported speaks for itself..... :rolleyes:

As I said, be constructive, and post results yourself. You can then rule them out..... that way you can help others ;)

---------- Post added at 03:05 PM ---------- Previous post was at 02:55 PM ----------

Wi-Fi drivers are nothing to do with modem. They are compiled with the kernel. ;)

If re-flashing the kernel doesn't solve it, then you can probably rule that out.

I don't expect it to fix anything, but if it bothers you (like some), worth a try. :)

You can find the stock P6800 4.1.2 JB kernel available for download in my P6800 kernel thread. Flash in Odin or CWM format. Or try the complied SkyHigh kernel....

I was wrong, you are being supercilious.

There's an old saying, you catch more flies with Honey then with Vinegar.

While you may well be a good technician you have a lot to learn about interpersonal skills and trying to get the best out of people.

I am the OP of the thread and I asked for specific information in the OP, while your input could be helpful it's not being at the moment and if you wish to collect a different dataset then the one requested in the OP then I suggest you start your own thread.

Until we've collected enough information from enough different setups there's no point trying specific this fix or that fix scenarios as the sample base is too small, this is called a scientific approach to a solution rather then a shoot and hope approach.

Thanks for your thoughts, but can I ask you not to comment further in the thread until we've got a big enough dataset to actually be able to work towards a solution that will apply to all users.

" Re: Could people please test 5Ghz WiFi on Stock JB" is a request, since of which users have replied. This is not development, but an open forum for discussion on topic of the title. We both have got sidetracked.

Just a thought,

For those who 5 GHz band is not visible in Wi-Fi analyser app, maybe the band is not enabled (for whatever reason) on your device.

There are Samsung secret dialer codes that MAY give you access to hidden menu and check/enable/disable Wi-Fi 2.4/5.0 GHz bands. The hidden menu is not always visible though....

Sorry, I can't check with a P6810 device, and my SGS4 uses different codes. So can't do the checking/testing for you.... ;)

?? WLAN ENGINEERING MODE ?? (May not even work on your device)

Type into your dialer :

*#526#

-or-

*#528#
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] xaadilhx:
These codes for hidden menus don't work I think since ics, I have searched but a waste of time, couldn't find anything useful to get those menus. It appears they are filtered or blocked in the dialer, only imei code works now.

I guessed they were blocked to prevent malicious sites erasing your device. you'll need an app or an alternative method for such things. But I couldn't find much info.

Can we do another collection for this.......

If you have 5ghz WiFi working on your tablet under JB can you please let us know where your tablet is from and (if you can remember) what you previous ROM version was.

If you don't have a 5ghz lan to log onto you can install wifi analyzer from the App store and when you have a graph press the screen on the upper left area just off the graph and the mode should change to 5ghz so at least you can see if it's working.

I'm determined to get to the bottom of this.

My 5ghz WiFi still doesn't work, I've not changed anything my os since Samsung released the Asian 4.1.2. I supposed they still cared just a bit about their Asian sales while rest the world should officially be on 3.2 if they want security. Great reason to have a premium tab that can't be properly updated.

I'm a bit annoyed at Samsung and many manufacturers who promote and sell lovely hardware then **** on their customers, pardon my French. I previously had the Omnia hd Samsung phone with Nokia os, both Samsung and Nokia left us in limbo, the community had sort out their ****.

I'm still living with my Nokia n8 they're dead and ms Windows phone isn't very exciting. Android and their security holes keeps popping up and manufacturers can't issue appropriate fixes. Our father figures at Apple keep it clean but I'm not a fan, they take way too long get anything simple implemented.

1gb ram on my 7.7 isn't the greatest presently. I doubt Samsung will throw kit Kat at us, probably better release a new model to replace the 7.7 and sell us hardware can't use properly yet. Approaching 2 years so, are we stuck?

The tab 2 and similar less capable devices see more attention. So forgive my **** but I think in the future perhaps I'll try good old Chinese devices, they're getting better, less likely explosions, much better, right.

O cool the hk jb works with 5ghz, can't be bothered to switch, too much to backup for 5ghz.

Someone passed me a TGY (hongkong) tab running on honeycomb, which I flashed to TGY ICS via kies, then to XSP (singapore) JB via odin. No wipe was performed, and 5GHz WIFI was working great.

However the tablet was getting SODs with the top left hand corner getting warm, so I tried to wipe via Settings. Afterwards, I noticed that the initial language selection screen defaulted to "Bahasa Indonesia", and 5GHz wifi was not working anymore. Tried to wipe again via recovery and the same observations persisted.

So I wiped a final time and booted straight to bootloader to flash XSP JB via odin. This time the language selection screen defaulted to "United Kingdom", and 5GHz wifi was working again. :cowboy:
