WIFI disappearing problem with WM6.5 - a partial solution

[Guest pdaphonemaster]

Hi All,

There are a coupleof threads here discussing WIFI problems with 6.5

The nature of the problem is that WIFI would disappear from the list of netwroks and can't be activated. This can be becaused by changing a registry value for some minor fix (e.g. showing setting in start menu, etc.) and any number of program conflict. My experience is that there is no application that cause this all the time.

However, I learnt that SKTOOLS would fix it. I followed the suggestion of a poster in one of these WIFI threads to use (advance) clean. and it works. If you have this installed, do advance clean and delete everything it finds, cold reboot and WIFIis back.

So, now whenever I need to turn the phone off I do SKTOOLS advance clean first and turn it off. Then WIFI is there next time I turn it on.

I am using WM6.5 JD. I have not had a hang in two days since I falshed to this firmware. Fingers crossed.

Hope this helps.

EDIT: Well this fix works approx 2/3 of the time.

EDIT 2: Sometimes, advance cleaning needs to be done twice. Do it one and then select rescan, delelte all then switch off and switch on. So far it has worked fine.

EDIT3: Flashed to Secany's latest rom IK1. So far no WIFI disapprearing probelm even under the same program set up that would have caused problem in earlier roms.

Nice quick fix, you say you have not had your device hang in two days? I've not had mine hang once yet, or am I just being lucky?

I get wifi missing for 2 reasons when i done upgrade to IJ9 and also playing with the Windows plugins. I can confirm it as i had tested and hardset at least 10 times to find out the problem

1) Installing of Spam alert Spam alert v 2.1 - the wifi goes missing after that

2) Using SK tool advance cleaning and then delete everything that it listed. - wifi missing after that and soft reset does not bring back wifi.

Above is happening to my phone which is very different from urs... so i duno wat happen .. haha :D

My WiFi disappeared too! I think mine happened after I did an optimize with SK Tools - I also had a weird problem where the selected item on some of the windows dialogs was invisible). I tried various solutions people have tried here but my WiFi wouldn't come back and I was thinking I would have to hard-reset (I dont want to have to do that !!!!!).

I found a post on modaco from somoene else that had this problem on an i910 phone. They had a solution that seemed weird but it worked for a couple of people so I gave it a try and it worked for me too on i8000 :D This is what I did:

1. Enable Samsung Widgets for Today screen in the Display settings

2. Drag the network connections widget onto the desktop

3. Try to turn on wifi with the widget. It isn't able to activate WiFi

4. Using the widget, turn off bluetooth, phone, wifi, then turn bluetooth and phone back (by clicking on the widget)

5. Now use the widget to enable Wifi but WHILE IT IS TRYING TO ENABLE, press the power button on the phone to turn the power off.

6. Power phone back on and now my WiFi option has returned from the dead!

I am glad I avoided a hard-reset - I hope this works for other people too!

I think before this I had no problem with my wifi until I using SK Tools. My wifi can't be activated even after soft reset. Try activate on Samsung setting and shows it activate, but on Microsoft setting it still off. Trying with steps provided by dgmorland and it’s worked! Whoever had this problem, you should try this.

Tested and working!

My Wi-fi is disappearing too!

My i8000 was shipped with 6.5 already and the problem was there before with the old original build. Now - I've upgraded to the new build an the same happen. Wi-Fi disappearing periodically. I'm also using SKtools. But for me the wi-fi does not gone after using the tool (several times).

It's was gone after a couple of soft resets (was installing stuff..)

Then came back after a few reboots.

I'm my opinion i think it's may: a.) a faulty wi-fi device inside b.) most probably- a bug in the firmware

i HATE this BUG !!

Thank you for sharing this! I confirm it's working (and probably many others) after reset.

I just realized today that wireless wasn't working. I'm not sure what caused it since I haven't installed anything in a long while.

Even more: I have the original rom and never installed SK Tools. I did however used a couple of registry customisations from here:

http://www.samsung-omnia.org/how-to-b57/i8000-user-manuel/

I'm pretty sure they were the soft ring (#26) and auto disconnect (#29) (did not install any app to disable the connections).

I also lowered the autodisconnect from GPRS (taken from a websearch):

HKLMComm\ConnMgr\Planner\Settings\

Click > CacheTime > Value Data, change from 600 to 60

Besides those the only notable thing I remember is enable a Null connection (Instead of Internet or Work) to bypass the gprs connecting by itself.

So, I think the issue is some registry setting that's affecting the WiFi.

Yesterday I had the no-wifi-anymore bug the third time, and in all three cases, it happend using Opera Mobile 10 beta. I was browsing around with Opera, then suddenly Opera and the whole system crashed completely, I had to do a soft reset on the back, and after that the wifi adapter was missing. The first time I did a complete hard reset, but wifi was still missing.

I came to the phone preconfiguration through *#1546792*# (a lot of google-ing brought me to it), where the settings were at some country I can't remember, switched it to germany, and *wohoo* my wifi was back. The last two times i just did a soft reset, went to the preconfig, there was already germany set, but as soon as I left the menu and rebooted my phone, everything was fine again.

Maybe this helps anyone.

I have no idea if really Opera caused my wifi to dissapear, but three times it happened just when I was using Opera, and I'm using my Omnia a lot with other programs and gadgets...

I was just going to post the same issue regarding Opera! :)

I managed to get the WiFi disappearing again (a few minutes ago) while browsing with WiFi enabled using Opera (the one on the phone).

For some reason Opera hanged and after I reset the phone I had no wireless (so had to do the above procedure again)

Btw, you can do an extra step and disable the phone (annoying gprs connecting for me) like: phone off, bluetooth off, phone on, bluetooth on, phone off, wireless on, reset.

Verizon Omnia2 user here -- WiFi has completely dissapeared from the Samsung network manager (Tap top bar, click the staircase signal bars with the two arrows)..

Just has Airplane mode, phone, bluetooth, and Data connection.

If I tap "Menu" at the bottom, I get phone settings and bluetooth settings.

I know from memory that this menu used to have a "Wifi" entry in both the menu at the bottom, and in the list with a button to activate or deactivate it.

If I go into start, then settings (I have now and have always had touchjizz disabled), then Wifi Settings, I get the "Tap here to turn Wifi on" Samsung stupid UI thing, I turn it on, and it looks like it's getting turned on, and says "Searching.." but it really doesn't do anything, and no networks are found. I can press search again, and same thing, nothing happens. I know this is probably what everyone else has happened to them as well when Wifi stops working, but I just wanted to explain it a bit more for anyone else who has this issue so they know what to look for.

The strange thing is that I, like most of the others here, have not installed any programs or made any major system changes since the last time Wifi did in fact work OK. The only thing I have messed around with is Opera Link (using 10 Beta 2) -- and since a few of you mentioned Opera, I figure that is no coincidence. I have yet to try any of the suggestions mentioned (SK Tools, etc.). I will edit my post later on with what I have tried and hopefully a solution, if I am able to find one.

I have to say this -- this DEEPLY concerns me that a device like this could suffer from such a bug...you would think...ehh I won't even go on about it anymore, it's just kind of disturbing B)

There is a simple fix for this, please refer to this post.

I will reproduce it here to avoid confusion:

Go get WifiProfiles.

Create a new profile

DHCP:YES

Net Adapter: SWLDM201

Enable wifi: Yes

Apply the created profile and your wifi should be back.

Please keep in mind that after doing this, WiFi is ON even though it might not be shown ON in the widget. You will need to manually turn it off if you're not going to use it in that exact moment.

Thanks, but if I do this and get it to work -- then uninstall the program, the Wifi goes away again, heh..

More testing -- if I install the program, apply profile (wifi comes back and works), connect to a network and browse, then shut down phone, and turn on again (program is still installed), wifi is still gone. It seems while this is a fix, it is just a band-aid.

If I need to use Wifi again I would need to 1 keep this program installed, and 2, open it and hit "Apply profile" Every time I would like to use it.

I would really just like to go back to how things were a week ago :) where WiFi was present in the wireless manager at all times.

Anyone know what is the root cause of this issue?

A couple of posts have hinted SK Tools is the cause in the previous thread, but I've had SK Tools installed since I first got my phone and only experienced this issue recently, and have not even used SK Tools's clean function or anything else really in quite some time.

It's not SKTools it's any data connection. You probably didn't use much data connection before it "happened", like in my case. Whether gprs, hspda or wifi, it may cause your wireless to "disappear". I didn't have this issue until I started working with gprs. Wifi was working fine for a couple of weeks, no issue. Started working with gprs more frequently, wifi magically gone.

I found it's more inconvenient not to have WifiProfiles (in MyStorage) in this case. I've tried everything else, but this is the simplest I could come up with. I imagine the most simple solution would be to extract the registry keys that are over/written when WifiProfiles start. Until then, it's either WifiProfiles or shutdown-while-widget trick. Or no wifi, which I imagine is not that convenient.

[Guest surgex]

Thanks for the info Ender.

I am going to work on this with a friend and see if we can find the exact cause.

[Guest PCSPhone]

It's the WIFI driver that stop responding for an unknown reason. If you have SKTools, just go into the "Devices driver" menu and restart "$device\NDL1". To do that use the STOP then START action and the WIFI should come back.

[Guest Aurelius]

In my case nothing works...

Wi-fi disappears very often and sometimes even SKTools and reset is not a solution.

I have and old rom and didn't see the point to flash O2 till now.

But I wonder whether the problem still exists in the newest secany's rom A5?

Edited January 26, 2010 by Aurelius

[Guest Chainfire]

I am not having this issue, so perhaps a dumb question:

Does this happen on both I8000 GSM as well as I920 CDMA Omnia II or both?

[Guest msegmx]

WifiProfiles worked for me.

but I've also noticed the change of the reg. value

HKLM\System\State\Hardware -> wifi

from 0 to 1 after I enabled wifi successfully via WifiProfiles.

Now I made a test and set the value of 'wifi' to '0' (zero) and voila.. the Wifi option disappeared.

After reenabling wifi option with WifiProfiles the value was 5 (five) ??

I'll try to enable the wifi option this way, but I couldn't make the Wifi option disappear again *lol*

I'd say try it, and please let me know if it made some difference.

But i done only the regetry fix, with out the wifiprofiles instalation!

it's working for me..

thanks m8.. u save my day :(

[Guest Travis cn]

I got the wifi missing problem recently. I have tried every thread but it still don't come back :(

In the menu Samsung setting-system-version-device, there is noting besides MAC under the "WLAN(IEEE 802.11 b/g)" item. In the past, when the wifi worked, there were figures there.

Please let me know, when your wifi is missing, weather the "WLAN(IEEE 802.11 b/g)" contains S/W, H/W and MAC figures.

Some one tell me, please!

Thanks you saved my day.

How did you find out that the "$device\NDL1" driver was to blame?

Is there a way to let that driver start as the last driver?

As it seem to work if it is restarted when all other drivers run.

Every time I 'soft reset' the WiFi problem is back, as WiFi disappears from the wireless manager and can't connect.

I restart the driver "$device\NDL1" every thing are working, solved, but still a small bug.

Just thougt I would share this, I tried manually starting the wifi driver with sktools but it only worked once for me, however what I do now is to turn off my o2 and leave it for 30 seconds then turn it on and bingo my wifi is back, this has worked every time so far.

So it looks like that when you leave it for those 30 seconds the reg changes are saved so that when you turn on the device again the wifi driver loads properly.

[Guest Sapfizz]

I am using the official Turkish 6.5 ROM - the loss of wireless was a real pain - when I was in the UK I went to a Samsung agent and told them of my problem and also that I was having problems connecting with 3G (which was also true) - when I phone Samsung about the problem the more or less told me to get lost and take it back to Turkey (thanks Samsung) - what I actually did was told the Samsung agent that Samsung had said I should make sure it was flashed to the latest software. So they did - everything seems the same (PDA, Phone version, etc), but now be default I have all the UK service providers instead of Turkish ones, since then I have had no problem with wireless or 3G - when I got back to Turkey I put a Turkish SIM card in and it picked up 3G here no problem at all.

Don't know if that is of any use to anyone, or gives someone a clue as to a real solutin to the problem - but I thought I would mention my experience of it.
