WiFi Tethering Issue

I rooted my Droid Incredible today using Unrevoked's one-click rooting process. The whole purpose of doing so was so I could use the wireless tethering feature. However, now that I have successfully rooted the device, I cannot get ANY application to work. I have used numerous programs found within the Android Market (Barnacle, etc etc) and have also tried the tether application that comes pre-installed with Android 2.2.
When I activate the wireless tether, the wireless network does not appear so other devices can connect to it.
I have searched the forums inside and out. I have tried the ##778 method suggested in this forum: http://forum.xda-developers.com/showthread.php?t=752687 and it did not fix my problem.
Any and ALL help is deeply appreciated! Thanks in advance for your time.

I checked that thread you mentioned and it didn't seem very thorough. Here's something that I wrote on Android Forums that works for non-rooted Incredibles:
This works great on my Incredible. No rooting required, but you must have the 2.2 update which enables the 3G Mobile Hotspot on the device.
1. Select "Phone"
2. Dial "##778"
3. Select "Edit Mode" on pop-up dialog box
4. Enter "000000" for Please Enter Password (unless you manually changed your password to something else)
5. Select "Security"
6. Select "S.IP DUN User Name"
7. Delete the "dun." part of the number (ie: it should read as: [yourmobilenumber]@vzw3g.com)
8. Select "OK"
9. Press the "BACK" button
10. Select "M.IP Default Profile"
11. Select "DUN NAI"
12. Delete the ".dun" part of the number (ie: it should read as: [yourmobilenumber]@vzw3g.com)
13. Select "OK"
14. Press the "MENU" button
15. Select "Commit Modifications"
16. The phone will reset
17. Once booted, go into "All Programs", select the "3G Mobile Hotspot", Adjust your "Router Name" and "Password" (if you desire, but recommmended), and change the security to WPA(TKIP) (this is the only setting I've tried so far-other posts said the WPA2 is buggy)
18. Select "3G Mobile Hotspot - Press to turn on" (It will prompt you that you need the Verizon Mobile Hotspot Feature- just hit "Do not remind me again" and "OK") (Also, I am using Windows 7x64, and the wifi picked up the signal right away, but it took a moment to identify-but it connected to the internet cleanly and the connection is fast).
It can't hurt.

doesnt work for me, sorry

don't use the verizon wifi hotspot application. you need to install the corresponding kernel (Hydra stock undervolt is a good one for Sense) and Wireless Tether.apk to get it to work properly.

I ran unrevoked, rooted my Incredible, and installed Wifi Tether and it has been working flawlessly for me. I didn't do anything with a custom kernel.
What I had to do to get the app to work, is I had to go grab an older version of wifi tether from the developers site and install the apk manually. After that, the newer market version started to work properly.

is ##778 a sense only thing? when I call that or ##778+ on miui I just get a call cannot be completed message

All I did was run unrevoked and then get the wifi tether app.

Same here
Ran unrevoked then wireless tether-works great
Also did #778 - works fine too (only about 500k on either one)

huh, must have fixed the issue with the kernel since the last update. i remember that was one of the first things i did when i rooted was get the wireless tether working and i had to download Hydr kernel to get it going.

WiFi hangs when switched on

Hi folks,
Since last thursday I've got a problem with my WiFi on my wildfire. Every time I turn on the WiFi (via not. bar or settings) the little box is ticked but it does not scan or anything. A couple of seconds later I get the message that the WiFi process in the settings app is not responding together with the option to kill the process. Is my WiFi broken now? Or is there a fix?
Thanks in advance
P.S. I'm using CM7 7.1.0

Try flashing the latest nightly or the 7.1.0.1 update.

It doesn't work. When I boot after applying the update after the bootanimation there's just a black screen. It hangs. I pulled the bat and tried it again but the same...

Usually this can be solved by wiping the dalvik cache, have you tried that?

I managed to update CM7 to 7.1.0.1, but Wi-Fi is still not working! It just hangs after switch-on. And the weirdest thing of all is that it just happened, I dind't change anything or install any new apps...

Try reflashing the radio?

Reflashed the radio, still no progress It just wont find any wifi networks and after leaving the settings app the WiFi is turned off automatically (or the app hangs and the same happens) Any other suggestions?

By the way, WiFi-Tethering does work. Still confused about this weird problem :S

Try this in a root shell (enter "su" at the prompt) with wifi enabled:
ip link set up eth0
Though the name might be different on your rom, it's commonly named "wlan0" (eth0 is usually a physical ethernet device). You can find out by running
ip link show
With wifi disabled and enabled, see what new device comes up or disappears. It doesn't hurt to test a name, as long as it isn't "lo" (the loopback device).
After setting the link state, re-scan for APs.

Could you explain these steps? I'm not so familiar with terminal inputs and especially IP adresses. Whats more strange is that my Wi-Fi disconnects automatically when leaving the Wi-Fi menu and that it doesn't show my saved accesspoints (once connected but not now). Isn't this a software problem?

Sure, here's the html formatted manual page. A relevant excerpt:
ip link set - change device attributes
dev DEVICE
DEVICE specifies network device to operate on. When configuring
SR-IOV Virtual Fuction (VF) devices, this keyword should specify
the associated Physical Function (PF) device.​
up and down
change the state of the device to UP or DOWN.​

When the device is down, it won't scan. Some ROMs have a different tool installed as /system/bin/ip though, just typing "ip" will tell you.

The saved networks aren't shown when wifi is turned off. It likely fails to enable the device and does this before attempting to read the saved networks, as this should never happen it might be related to the radio firmware on your phone. See this thread for the list of radio firmware versions. As for disconnecting when you leave the WifiSettings activity, wait a bit longer to see if it stays connected. There's definitely no intentional disconnect in the onPause handler.

I've tried your steps. When setting the IP link to up after switching on WiFi and then enter 'show' i get a whole page of numbers and complicated text, but in each line the State is specified as 'DOWN' or 'UNKNOWN'. It also says something about a loop? When I leave the terminal then to check if WiFi is still on, I find it turned off. When I turn it back on and then let the terminal show, sometimes I get 'DORMANT' and sometimes I get 'DOWN'. I also tried your suggestion about leaving the client on, it stays on for about a minute before it automatically disconnects or gives me the message that the system app is not responding. My radio is already up to date (I even reflashed it twice). And what was that link 'WiFiSettings activity'. I came to a website with lots of code and got immediately confused . I hope this problem can be solved....

This is the RFC2863 state of the interface which is seldom relevant, the actual link state is between < and >.

That would be the loopback device. It is always present and its parameters are the same across nearly all Linux kernels, one might be funny and try to change the mtu, queueing discipline or address but it's pointless to do so.

According to the documentation, DORMANT means
Interface is L1 up, but waiting for an external event, f.e. for a protocol to establish. (802.1X)

This could indicate a problem with wpa_supplicant rather then the radio firmware. Try to connect to an open AP such as the ones at the local Bakker Bart, NS station, McDonalds or T-Mobile shop.

It is the actual source code to "Wi-Fi settings" where you normally see the list of networks.

Thanks for your explanation. So what should I do/try now? I was thinking about reinstalling the settings.apk and settingsprovider.apk ....

I tried that at the McDonald's and it didn't want to search for available networks, so I couldn't connect

Go to settings > Wireless & Networks. Disable this option
Mobile network
Use phone for data connection when Wi-Fi is unavailable
It should change to
Mobile network
Connect to the Internet

Try going to /data/misc/wifi and rename the wpa_supplicant.conf to wpa_supplicant.conf.bak and try again, the system will recreate the file.

[Q] [HELP]My Kindle Fire Won't Turn Wifi On

last night I was reading online comics and it suddenly not respond so I force it restart and it was worse. My kindle cannot recognize my touching.
It is strange that TWRP still works. Restoring doesn't helps, too.
So I wipe it all(except for sdcard) and install various cm9 and cm7 with corresponding kernels from hashcode with no luck. Cm9 is ok but without wifi. Cm7 just wont respond.
Also I tried using TWRP to go back to pure stock and wifi still not working. So I redo all the root, twrp again.
Finally I fix permissions and install cm7 aka now it's screen recognize my touching but the wifi still cannot be turned on.
Is it possible wifi chip has been broken?
Any one can help me, THANKS!?

hey everyone, do u have any suggestions......
now, as long as I open wifi it goes dead. I don't know what to do. Is it possible that due to heavy use the chip gets break down?

I was wondering what remains the same after I flash roms. Because installing zip has formatted boot, data and system.
I hard off the device when the wifi went wrong. And the application in which led to this situation cannot be reinstalled(install said OK but openning it the screen was black, still responding to button savior).
So maybe the problem lies in the internal storage that is unchangeable. Any one helps!? Or should I contact amazon CS?

But why the wifi still cannot be turned on? yes, it is when I using the app the wifi connection seems to be unstable, and I pressed the power button for 20 seconds.
Thanks for your reply.

would try to clean up the wifi configuration:
turn wifi off
look for /data/misc/wifi/wpa_supplicant.conf
open the file and delete everything except the first two lines, they are:
ctrl_interface=tiwlan0
update_config=1

this is for stock rom - for cm7 it has to be simmilar
turn wifi on again
hope this helps ...

I used root explorer to search for wap_supplicant.conf since it's not in that folder and delete everything except the first two lines. (forget to mention that my wifi just shows turning on and I can't do anything, flash new roms won't help.)
Then I reboot it the result remains same.......

did you try to restart your router ?
because i have this sometimes with the stock rom - wifi tries to connect and can't - all my other devices work fine - i use to reboot to router and the kf is connecting immediately again

I'm sure it has nothing to do with my router. because I live on campus and use school wifi. wifi is in the state of turning on since booting. regardless of flashing new roms.
thanks for your reply.

just closing out all known issues ...
but nearly running out of ideas at this point
maybe something on your sdcard partition ? - i know it sounds crazy but i had a case where the fresh installed rom did not start until he copied the whole sdcard partition to computer as a backup and deleted everything (besides .android_secure and twrp folder)

I can only think of files remain unchangeable when flashing roms or wifi chip burned(hope not).

actually I'm just a noob. I don't know how to do a logcat and how to find the problem.

as you can't download it from the market, attached here is a logcat program
install it and you'll see a lot of debug lines - be shure to make or let make the kf a wifi connection attempt - save the log and attach it as .txt file to the thread - i'll take a look if i can see something to track down your problem

the thing is the wifi is turning on by default. no matter what I do. do u mean use some app which needs wifi?

im kinda curious if you find a fix. ive been struggling with terrible wifi connection with my kindle. itll turn on, but it constantly turns off then after a while wont connect anymore. just says obtaining wifi then doesnt connect just shows saved wifi connection. im almost to the point of giving it away. not sure if amazon will help me out, and i wouldnt sell it to someone if i know it has wifi connection issues. i try to reset my router and it helps for a little bit, but then goes back to the issues i had

seems like we have different issues. Mine is turning on without any connection or list of available networks. Have you tried reboot, forget all networks or so on?

Does your wifi toggles keep repeatedly flashing and turn off. Test my method!

My LG G4 started acting really weirdly and the WiFi would randomly turn off as well as repeatedly flash so i tried this and it began to work perfectly.
1. Go on to dialer
2. Type this code *#546368#*815# in
3. You will enter the secret menu
4. Then click on Field Test
5. Scroll down to wifi test and click on it
6. Then select OTA settings and press enable.
7. Now test wifi
I am not responsible if your phone breaks or something etc.
I really hope it works for you but I can not guarantee it. Let me know if it works for you!:good::fingers-crossed:

Wi-Fi won't connect -Wi-Fi Connection Failure

I'm having a huge issue. My Wi-Fi won't work on my 2013 Nexus. I select it. It sees it with a full signal and I put in the password, It just says saved. I tried with a connection without a password, it says the same thing. I tried flashing back to factory multiple times but it does nothing. It was working and just all of a sudden went out on me. Is there a way to flash a driver or something?

Firstly, just reboot the WiFi access point and try to connect to it again.
Did you change firmware or any settings on the WiFi access point? Do other devices connect to it properly?
Can your Nexus connect to other WiFi access points? Try it with your mobile's WiFi hot spot.
Finally, we need some logs:
turn off N7 wifi
start logcat (I prefer 'time' format: adb logcat -v time > log.txt )
turn on N7 wifi
try to connect
stop logcat
compress and post the log here
