[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] ciobi:
I have a Hong Kong 6810 and it was working fine with HC, but then the official Samsung ICS 4.0.4 update came and it brought with it the WiFi dropping issue. While it disconnects itself every few minutes, it usually reconnects back immediately on its own. So for me it's not a huge issue, as I mainly read news, but it's annoying nonetheless. I had no such problem with HC. I'm pretty sure I never had a disconnect.

This was mentioned before and worked great for me: in my router's settings (HUAWEI HG655b) there is a "channel", which can go from 1 to 13 and is "auto" by default. I changed the channel from "auto" to "5" a day ago and didn't have any disconnect after that.

There is another strange thing: In my router's list of connected devices there are too many entries. On closer inspection it turns out that they have very similar MAC addresses. I'm pretty sure it's my tablet that presents slightly different MAC addresses to the router, and I wonder if this might be related to the dropped connections. Although I've never seen anything besides 18:46:17:EE:2B:2F when going to Settings / WiFi / Advanced, the router has entries for 18:46:17:EE:2B:FC or 18:46:17:EE:2B:F8. I'm pretty sure nobody is trying to duplicate my MAC address. Well, I'm no networking guru, but this looks strange to me. Is this related to the 6810 having dual-band WiFi? (Still, at some point there were 4 similar entries in the router's list.)

I am Singaporean and thought downloading the Singaporea firmware will make my wifi better but nope still the same issue. The weirdest thing is there is absolutely no problem at all when connecting to my wifi at work. Only at home then all the disconnects appears and the endless scanning even though the wireless signal is excellent.

Yet I have no problem at all on honeycomb. Something is seriously freaky here.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] GR8 Ride:
I have been running the newest Chinese version of firmware, and while WiFi isn't perfect, it does at least appear to be somewhat reliable.

It will disconnect on an irregular basis, however it almost always seems to reconnect without any issues. I no longer have to enable Airplane mode (for some reason, my 6800 would only reconnect if I enabled Airplane Mode and then disabled Airplane Mode; turning WiFi off and then on again didn't work). All of that was on the previous (LQ1) version of the Austrian firmware.

It's better than LQ1, but I still don't think it's solved.

Well,

I promiced to give a feedback so here it is:

Since the begining i installed every ICS rom that was released and on everyone i had the wifi bug. Until today when i installed the indonesian firmware. This one works great until now, i mean i have 5 hours trying to reproduce the wifi bug. I goes around the wifi free spots in the city, i go home, at work , at friends and every time i got connected without problem. Searching is not an issue, everything is going smooth. I stopped the wifi in any ways that i could imagine, i rebooted, i erased the wifi profile etc, every time i got connected without any problem. Still, because so much time i had wifi bug, i'm affraid to tell that the indonesian rom is wifi bug free. Anyway, here is what i did in order to update it:

In the begining I had HC stock romanian firmware. I flashed ICS indonesian one downloaded from sammobile with mobileodin v3.0. From mobileodin, i checked both wipes and i press flash firmware. And that's all. Seems that i had luck.

My router is on wpa2 personal, it has dd-wrt and the power is set to 71mv. It's a linksys cisco wrt610.

I hope that this post will help someone.

Thank you.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Jola013:
I have a combination of routers that allows me to replicate the wifi bug without fail, and also to get the P6800 to work (only with Austrian 2, best of the lot).

I have tried Austrian 1, Austrian 2, Indian and Hong Kong, they all have the wifi bug. I have not tried the China FW, I don't think that it will suit me.

I am getting a bit tired of this, so not too keen to try the Indonesia, seems like a waste of time ? But maybe I will.

Another question : why does the heading of this thread say that this problem has been partially solved ?

It has not been solved at all !!!
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] sos_sifou:
because you didn't read the edit, it says look at post 53 i think, its an app on Google play who reconnect the wifi after the drop, well its partially solved but still annoying :(

I've tried china one but this one not have google play store... i was unable to install it even i download it as a stand alone app. Anyway, if you try indonesian one, please let me know if you still have wifi bug or not. As i described above, i got connected on 12 different routers without problem and now i have more than 7 hours without sudden disconection. I made heavy downpoad work using atorrent (more than 2G) and i have no intrerruptions, also i was watching live tv more than 1 hour...

Please, more feedback about the Indonesian firmware?

best regards

Sifou

Galaxy Tab 7.7
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Jola013:
OK, I have tested the Indonesian software.

Not bad, but the wifi bug is stll there, works similarly to Austria 2.

I can get wifi to work if and only if I switch one of my routers off, ie I only have the one router switched on.

As soon as I switch the other router on the wifi dies, even if I am not connected to the second router.

When I use my notebook I can connect to whichever service I like, even with everything switched on, makes no difference.

Router 1 : Asus RT-N66U, dual band 2.4GHz and 5.0GHz.

Router 2 : Huawei E585

Everything works fine with just the Asus switched on, but wifi dies when E585 is switched on.

Even if you switch E585 off, you have to reboot the P6800 to get wifi to work again,

At one site that I visit often, many of the neighbours have wifi, and the P6800 just will not work there (with ics, sure that will work with hc)..
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] sos_sifou:
thank you so much for the information, this is very helpful, at least it was the last ROM and the problem isn't solved yet, i don't know what Samsung are doing, maybe they think they are doing us a favor? pushing faulty firmewares and saying, look we promesse and we keep our promesses! of course with a crappie rom its easy, they can push a new one every month.

[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Jola013:
I did see that, but IMHO this is nonsense, the problem has not been solved at all.

The "Partially Solved" should be removed.

The chances are virtually 100% that when entering a busy wifi environment, such as an airport, that the wifi on the ics software will fail.

Even an apartment building, with many wifi networks, will cause failure.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] EduardS:
For me there is one way to get a stable wifi connection; disable mobile data, enter airplane mode and then activate wifi, This works each time. Maybe someone else can try this and confirm it's a workaround or again just something that does not work for everybody.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Jola013:
Hmmm, this seems to work in some cases, but I can still make the wifi fail by switching on a couple of routers.

The problem comes when the neighbours have routers that cause this issue, because you do not have any control over those.

Or at work, where there may be a few routers in operation.

I have left my tablet on the Indonesian firmware, this, and the Austria 2 firmware seem to be the best (subjective opinion).
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Jola013:
The P6800 with ics will not work with the Huawei E583c/E585/E586 mobile routers, and if one of these is switched on near the P6800 with ics then the wifi on the P6800 will stop working.

The Huawei device needs to be switched off, and the P6800 rebooted before wifi will start working again.

It is obviously possible that other routers could also do this with the P6800 ics.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] niceashwin79:
Thanks Sifou...

But it is again disappointment for me with flashing ICS on tablet.

Back to HC again..it has steady WIFI and I want it most at any case!

[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] ciobi:
I can now confirm that the tablet changes its MAC, as I've seen it reporting both 18:46:17:EE:2B:FC and 18:46:17:EE:2B:2F at Settings / WiFi / Advanced. So:

- Is this normal?

- If this is not normal, do other people see this behavior?

---------- Post added at 10:31 AM ---------- Previous post was at 10:22 AM ----------

Did you try to set the channel in the router to a fixed value rather than auto? I have a different Huawei, and setting the channel to 5 - the first value that I tried - fixed the problem for me. (I never had to reboot, though; my connection would go on an off by itself.)
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Jola013:
No, I have not tried that, will do so and report back.

I may also see if I can find any channels that do cause problems.

Hi all,

My girlfriend has an Arc S, and when she plays the phone becomes hot.

The phone is stock. (locked bootloader ....)

Would it be better to unlock the bootloader, to unlock like mine?

I have an Arc S also debrand, unlock bootloader ..

My Arc S virtually no heat.

Thank you in advance for your response.

Not his phone is not root, and not overcloker either.

I have not done anything on it, at least not yet. lol

Since it is still under warranty, can be a return to sav?
[Xperia Arc Q&A, Help & Troubleshooting] MrModMan:
return the phone if its still under warranty and unmodified and get it replaced with another Arc/Arc S

you can't overclock processor without custom kernel, and can't install an custom kernel without bootloader unlocked.

---------- Post added at 02:56 PM ---------- Previous post was at 02:54 PM ----------

it is normal to become hot because the processor is hight demand.
[Xperia Arc Q&A, Help & Troubleshooting] TheCrowNambourg:
So it would be normal as it is boiling?

A return guarantee would be necessary?

thank you very much for your response.

its normal for tha Arc to become very hot from the upper of the back i have the same phone so dose three of my frinds and all have the same proplem it gets very hot when you open wifi or internet in general or play games or make long calls on the phone but switching the network to GSM only and reduce brightnes of the screen to about 80% and turning off wifi help reducing the heat
[Xperia Arc Q&A, Help & Troubleshooting] MrModMan:
My Arc S doesnt get hot at all and i have CM7.2 flashed and underclocked, this might help your girlfriends problem

-root phone

-install a custom kernel (may not be needed for underclocking)

-underclock the phone (reducing heat on the phone, not recommended if you play 3D graphiced games)

that should make it less hotter... hope this helped
[Xperia Arc Q&A, Help & Troubleshooting] TheCrowNambourg:

Since it plays a Kinectimals, it is not advisable to underclocked?

Hi all,

I was wondering if anyone had tried taking HTC to court (I'm thinking small claims court in UK) for not giving those of us who purchased our handsets outright, full access to modify the bootloader etc (ie, S-OFF)?

I'm feeling some serious righteous indignation right now and am considering it.

Thought I'd ask if anyone from here has done it, or knows anyone who has, before I look too much into it. :)
[HTC One X] TheHEFTA:
Simple answer, No?

It's their product, they don't have to let you modify everything.
[HTC One X] ganny:
I doubt you'd have a cause of action for not being able to tamper with your phone.

Plus, you're obviously not aware how much it costs for such litigation. Even if you did have a potential cause of action, if you lost not only would you have to pay all of your own costs but may even have to pay some of the opponent's.

In any case, as much as I think S-OFF is awesome (and I'm continuously checking this forum to see when its available) I can understand why HTC would have shipped S-ON. Every time someone mucks with the bootloader and bricks, HTC will have to deal with fraudulent warranty returns otherwise...
[HTC One X] Nit3m4re:
Samsung don't seem to bothered by it though..
[HTC One X] anoniemouse:
My thoughts exactly, also the idea of a smartphone is like a miniature computer.

A fair number of us regularly install operating systems on those with no bother, why should it be any different on a phone.
[HTC One X] Ryan J Williams:
A product is sold as it's sold. Unless they specifically advertise it being able to do something and it doesn't you have absolutely no case. Bringing a lawsuit against HTC for not making it so easy to tamper (although it's not like you can't) is like bringing a lawsuit against Microsoft for not making it easy to flash firmware onto the Xbox 360. They never said you'd be able to, even if you can — any case would be thrown out and you'd lose a lot of money. Although you're welcome to try. ;)
[HTC One X] airchie:
Their product, which they sold to me. Why should they have any say whatsoever on what I do with it??

Why not, I own it outright?

The small-claims court in the UK is for exactly that, small claims. In Scotland/Ireland the max compensation is £3k and England/Wales if £5k. The whole point of it is for smaller cases and that it doesn't cost a lot to file a case.

Exactly, its only HTC that make it so bloody difficult to modify your phone the way you want. Why would they be faced with a bigger problem than Samsung etc?

Exactly! If I bought a PC and I wasn't allowed to change or even modify the OS, I'd be pissed.

Bullcrap. See my analogy below...

True, but the legality of MS preventing the modification of your own xbox is highly questionable at best...

In this thread, I see a lot of negativity, do any of you actually want S-OFF on your phones?

We're not going to get it unless we ask and there's absolutely no reason we shouldn't have it on phones we own.

Here's an analogy I was thinking of.

Say you buy a house and once you've paid and moevd in etc you realise the garage and the basement are locked.

You contact the company that built and sold you the house and they say that's right, that's how its meant to be.

You speak to your neighbours and they're in the same boat and none of you are happy about it.

So you all band together and complain to the company and they relent and say "OK, we'll unlock everything".

You feel vindicated and not long after you get a key in the post that opens the garage but not the basement.

Are you happy?

Of course not.

You want full access to the house you bought, and rightly so.

HTC know they've no right to lock you out of your own phone.

That's why they relented and gave us HTC Unlock but it's nigh on pointless without S-OFF.

And since they force you to accept you're voiding your warranty by unlocking, the comment about increased warranty returns is unlikely.

So, my thoughts are, if I, or anyone else files a claim in the small claims court for nothing more than the value of their phone, it will send HTC a strong message.

If that claim is successful, it sends them an even stronger message and opens the door for others to follow suit after setting the precedent.

I know its unlikely to be plain sailing but its not going to happen unless we try...

Well said & pointed out i agree with you
[HTC One X] treebill:
People took apple to court over jailbreaking, they claimed it was illegal as if was modifying it to run out of toc (should check reason why I believe that's right) but judge ruled against apple making jailbreaking legal in the US.

However HTC have got to keep devices as s-on due to contracts, debranding it would lose carriers money.
[HTC One X] airchie:
I'm not sure what you mean, can you clarify that?

My phone isn't branded (other than the HTC logo) and not on contract and I use a PAYG SIM.

The phone is outright mine and I'm not sure how giving me S-OFF would lose anyone money?
[HTC One X] anoniemouse:
Fair enough for branded phones, but unbranded ones there is no excuse for HTC not to make them s-off
[HTC One X] AUXRVIII:
Jailbreaking is done on top of the stock operating system, not replacing it, so it's not a comparable argument. HTC have the right to not allow mods to the system because they provide a warranty on the device when it's sold. No they won't sift through users whose warranty has expired, resources would be better used elsewhere.
[HTC One X] treebill:
I wasn't implying that its the same more that people have taken a company as big as apple and won.
[HTC One X] BarryH_GEG:
The only way you could go after HTC is if they documented a feature as being available and then didn't provide it. "S-Off" isn't a feature, it's part of the phones infrastructure as HTC ships it. Nothing is compromised in the use of the phone as it's shipped whether it's S-off or S-on so you're not being deprived of anything HTC intended to provide. In others words, based on the way HTC describes the phone, you've gotten what you paid for so there's no "harm" to justify a lawsuit. I'm not defending HTC's choice, but it's their choice to make. The simple solution is to not buy their phones.
[HTC One X] gwuhua1984:
I don't see the point of taking HTC to court. The comparison of Apple and HTC doesn't make sense. Apple doesn't want you to jailbreak period, while HTC is more open. To me, HTC s-on for a reason, if the users know they're doing, and gets s-off then good for them. Not like HTC will call you or send you a note that you'll get sued for getting s-off on your device. Just wait patiently for xmoo and Football to find the way to s-off, they are making good progress anyways.

I completely agree with you.
[HTC One X] airchie:
Its a large corporation trying to exert control over a device they've sold and have no legal right to try to control.

If that's the case, why do they make you invalidate your warranty to use HTC Unlock? And they can clearly see if a phone's been unlocked as we can't re-lock them. And it only takes common sense to see a manufacturing defect isn't caused by modifying software. There is nothing that justifies the way HTC are acting over this.

How so?

Something is compromised, my ability to modify my phone in the way I want to.

So by what you say there, you think HTC has a right to prevent me doing what I like to the phone I own? To me, that's like saying Ford has the right to stop me changing the wheels on my car.

The comparison of Apple and HTC is very valid. They're both trying to exert control over hardware they've sold when they have no right to do so. A fact proven by the Apple case.

My point is, we shouldn't have to wait for some enterprising users to break bast HTC's deliberate locking down of our phones. Especially if they provide the unlock option.

All I'm seeing in this thread is people saying things like "I'm not defending HTC but..." or "Why bother fighting for your rights..." etc.

Well, I think we should fight for what we want instead of rolling over and taking it.

The reason HTC, Apple et al all do these things is because they get away with them through apathy like has been shown in this thread, it makes me sad.
