Hi all.
I like remix so much. But i have 2 problem can't fix. I find all (i guess so) on google to fix it, but i can't.
My device: dell venue 11 pro i5, model 7139, windows 10 pro.
The first: when i boot, i can't use volumn key to selection windows or remix to boot, with keyboard ok (keyboard have narrow key). In boot screen, it's have the row " press ? and ? to selection ", the ? not volumn key.
The second: wifi disconnect and can't turn on after device sleep or stand by.
I try everything in google to fix it in one month but hopeless. I post this thread to get the last hope.
I am from Vietnam. Hello everybody.
My english is bad. So pls forgive me if i have mistake.
Thank so much.

1. Nothing to do with RemixOS; grub isn't really designed for tablets so doesn't pickup on volume buttons etc. unless supported by the bios/uefi. Check by booting into BIOS and seeing if the volume buttons work; my guess is they won't. That being said someone might be able to compile a version of gummiboot thatvwors with the buttons.
2. Which wifi module are you using? As a workaround rmmod $ModuleName && modprobe $ModuleName should work.
Thank you so much for your answer.
1 i understood
2 i type command in terminal but nothing happen. What can i do in next step ?

Try getprop in terminal. The last line might be wlan.modname. If so then rmmod and modprobe

Not a problem; at least that saves you having to reboot; which I know can be a problem on tablets as you need a keyboard hooked up to navigate grub.

Hard to say blind; anything show on logcat? Toggle wifi on/off a few times, maybe...
Perhaps:

Hello there! After months asking for the developer of Simple Streak Rom for a fix in the VPN connections (and no answer) I have been trying to fix it. Well, I made it! After several days of frustration, I have finally made it work
What do you need:
1. Working VPNServices.apk (I pulled from the PlayDoh ROM, which it is based on 354 ROM which it is supposedly the same of Simple Streak 1.2 Testing V4)
Links:
http://www.multiupload.com/E9RI0XOKCQ
Mirror:
https://sites.google.com/site/ernestovillarreal/home/VpnServices.apk?attredirects=0&d=1
2. Working tun.ko for our devices (thanks gpmg762 for that!)
Link:
http://www.multiupload.com/D3FXAJUC72
Mirror:
https://sites.google.com/site/ernestovillarreal/home/tun.ko?attredirects=0&d=1
3. Need to give special permissions to the VPNServices.apk. In a terminal emulator, or using adb, type:
Code:
su
mount -o remount,rw /dev/null /system
chmod 0644 /system/app/VpnServices.apk
mount -o remount,ro /dev/null /system
sync
reboot
3. Load for the first time the tun.ko. In the same console, type:
Code:
su
insmod /pathofwheretun.kois/tun.ko
4. Edit the init script to load the tun module every boot. Edit this file: "/etc/init.streak.post_boot.sh", adding this line to the last line:
"insmod /system/lib/modules/tun.ko"
ASSUMING you have the tun.ko in /system/lib/modules folder.
And that's it!
**UPDATE: It works! The problem seems to be my router, in 3G is working fine!!
**UPDATE 2: In my case, it is not working on WiFi. I'll try on other ones in the night.
**UPDATE 3: My bad, problem with the chmod. I have fixed it on the thread
**UPDATE 4: In the Simple Streak 1.3 testing 5, Splida added the tun.ko but he didnt add the VpnServices.apk nor the postboot modification. So, just skip step 2. And it is still not working using WiFi.
WiFi problem probably with dd-wrt router. Will test this night.
#Bump
This is awesome! VPN working on Simple Streak?! Downloading now.
Excited to use my blue tooth mouse with windows remote desktop (2x Client) away from the office and secured tunnel.
::EDIT:: working great on my WiFi!
Ok, so how do we script tun.ko? You could figure out how to run the insmod /data/tunko/tun.ko at every boot -TheManii, I'm looking at you
Or create a shortcut that will run tun.ko on demand and preferably connect the VPN with the same single click.
This is more of DJ_Steve's area of expertise I think, I dont really know much in regards to launching scripts on boot.
I guess you could make a script in /system/etc/init.d or just /system/etc
with
Code:
insmod /system/lib/modules/tun.ko
I dont see where streakdroid has it's scripts to run it, mabye it's automatic if it's in that folder? If it does in fact still need to be scripted i believe init.d runs with root privs?
Really I'm just guessing
May be you can try scriptmanager run on boot option

Guys, you can put the line "/system/bin/insmod /system/lib/modules/tun.ko" into /etc/init.streak.post_boot.sh, that loads it for me after a reboot.
Or you can use GScript from market to load it manually.
Hope that helps.

I've been looking for this for a while finally I got it, this is what I did:
- Connect your android device to your linux PC
- Enable USB tethering
- On your linux box as root (I'm using Fedora 16)
Code:
iptables -A POSTROUTING -t nat -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward
ifconfig usb0 12.12.10.1
With this you will enabled internet sharing between network interfaces and assign an IP to the usb interface.
- Enable mobile data access (3G) on your android
- On your Android using adb or terminal emulator
Code:
ifconfig rmnet0 0.0.0.0
ifconfig usb0 12.12.10.2
route add default gw 12.12.10.1 dev usb0
setprop net.dns1 8.8.8.8
The first line will disable the data traffic through your 3G connection so all the traffic wiil go through the USB
- Enjoy
All apps works because they see a vaild 3G connection!!!
WARNING: If during you are USB connected, the 3g connection is reset, the system will restore its IP and DNS so
the traffic will go through this interface you must reset again the IP to 0.0.0.0 and the dns to 8.8.8.8. Maybe
one of the devs here could help us to prevent this happened. You can always check the IP values of all interfaces by typing "netcfg"
Press Thanks if I help you
everytime,
bash: /proc/sys/net/ipv4/ip_forward: Permission denied
yes i tried with sudo, same output.
using ubuntu12.04 64 bit. all other commands are fine,

In Ubuntu you can re-direct to files you own as the user calling sudo, such as files in your home directory, but not system files
so try this:
sudo bash -c 'echo 1 > /proc/sys/net/ipv4/ip_forward'
or you can edit /etc/sysctl.conf and then run sysctl -p
secondary problem
Thank you very much for your post, this is what I was looking for.
I have configured correctly, ubuntu 12.10 and android 2.3.7 (Huawei U8650) but there is a problem.
Only works a few seconds, the first moments. In the browser takes more time, but when I open "play store" internet is disconnected. It seems they check applications and stop working, it's strange. Configuration is successful because it works, but only a few seconds ...
Seems to prove that internet applications not from the 3g and crashes ...
I have broken the wireless on my huawei U8650 and this is the only way I can access the internet
Thanks in advance
PS: I'm Spanish, sorry for my bad English.

check this http://forum.xda-developers.com/showthread.php?t=1371345
I recently bought a Nexus 7 Flo tablet running the latest Android 4.4. I've since been trying to spoof a MAC address on it, but for some reason the wireless card seems to refuse to use the spoofed mac no matter what I do.
There's a more detailed discussion what I've tried in android.stackexchange.com/questions/57922/wifi-network-not-accessible-with-modified-mac-address (forum won't let me link), but I'll repeat the main points here. I have tried both ip link set wlan0 address XX:XX:XX:XX:XX:XX and busybox ifconfig wlan0 hw ether XX:XX:XX:XX:XX:XX. They both result in the MAC address being changed as far as I can tell from the output of ip link and busybox ifconfig, but when connecting to a network with MAC filtering with the spoofed MAC address being allowed, the device fails to connect. /sys/class/net/wlan0/address also shows the spoofed address. If I use the device's stock MAC and add this to the filter on the AP, then the device connects successfully.
Has anyone experienced anything similar on KitKat devices?

No, unfortunately not. I ended up buying a Samsung Galaxy S II where I can change the MAC successfully for demo purposes. I would still really like to get this working on an up-to-date tablet though..

Interesting...
There seems to be a couple of suggestions here that I will try when I get back to work next week:
- Enable Airplane mode before changing the MAC, then turn airplane mode off again and your WiFi should work
- Deleting /persist/wifi before changing the MAC
- Using this spoofing app
Good news everyone!
/persist/wifi/.macaddr seems to be the key to changing the MAC, *and* it allows the MAC to be changed *permanently*!
Code:
$ adb shell
$ su
# cd /persist/wifi
# echo -n "112233445566" > .macaddr
# ^D
$ ^D
$ adb reboot
And voilà, MAC changed even after reboot, and connects without a problem!

Hi,
I stumbled upon your post. I'm trying to do the same on my Nexus 5. I found your method works in changing my MAC address but it doesn't change to the string I put in the quotes. What I found is that the address I end up with is the unicode values of the first 6 characters. Is there some special format for this file?
Thanks!

Hmm, that's quite strange. From what I remember, simply using echo worked fine for me.
What you can do instead is this:
Code:
echo -ne '\x11\x22\x33\x44\x55\x66' > .macaddr
Let me know if it works!

I'm guessing for some reason on the Nexus 7 it uses a text file but a binary file on the Nexus 5...
I also found a couple of ways to activate the new MAC address without requiring a reboot. This is useful if you want to be able to change MAC address dynamically using Tasker or similar.
The least obtrusive method I found is adding:
busybox ifconfig wlan0 down
busybox ifconfig wlan0 up
commands after the echo command. This will briefly turn off the WiFi adapter and when it comes back on it will have the new MAC address. I actually found the busybox ifconfig wlan0 up command isn't strictly necessary, at least on the Nexus 5, as it seems to get reactivated automatically after you take it down.
You can confirm the new MAC is in effect by opening a new terminal emulator window and running:
busybox ifconfig wlan0
Interestingly, if you go into Wifi Settings, under advanced settings it still shows the old MAC address but the WiFi adapter is clearly running with the new one as indicated by ifconfig and the ability to connect to a MAC filtered router.
Alternatively, toggling on then off airplane mode will also activate the new MAC and it even shows the new MAC under the advanced WiFi settings.
I like the first option as you'd be able to automate dynamic changes for a particular network without the risk of interrupting voice or cellular data connections when it happens.

I tried using the approach above to reset the MAC on-the-fly, but it doesn't seem to work on my Nexus 5 4.4.4.
For now I'm sticking with "reboot" at the end of my .sh script, which works well. Any thoughts / advice are appreciated. Thanks!
great but

Hello, I was given a Gtablet by a friend. Everything is in proper working order except for the wifi. The wifi will endlessly scan, never pulling up any SSIDs. Here's what I've done to troubleshoot:
Ascertained flight mode was off (it was)
Enabled wifi through the developer options (Did nothing)
Manually enter SSID/Security information (Claims that SSID is not in range)
Reloaded the OS (He had VEGAn Tab on there. I reloaded the 5.1 Beta. I don't know what version he had on there, oops.)
After a clean install I have the exact same issue, which leads me to believe it is a hardware issue rather than a software issue. Is this common? Am I forgetting something? Would loading an entirely different ROM be of any use or do they also use the same driver?
My apologies if this has been answered previously, but in all my searching I can only find people who have this problem temporarily; a reboot fixes it for them. I haven't been able to find someone who has had this as a persistent issue.

I'll have to look at some logs to ascertain what your WiFi problem is.
Run the commands in this post (after rebooting the tablet) and then post the text files that're created.

Thanks, see attached are the logs as per request. As a side note, now that I have the terminal emulator on there I tried a few commands I dug up on the internet after I looked over the logs.

Both gave an error message
Code:
error: SIOCGIFFLAGS (No such device)
Also
Code:

The wireless LAN interface name on the gTab is wlan0. Hence your error messages: "No such device" for the ifnames tiwlan0 and eth0. (The latter would work for the ethernet I/F on the dock--if you had one connected.)

1. You have to look at the Android system logs (using logcat) to see the result of that svc command.
2. Your Android logs indicate that your WiFi interface is a) disabled at startup and b) then not enabled thereafter:
Code:
01-07 23:21:10.429 V/ConnectivityService( 990): Starting Wifi Service.
01-07 23:21:10.429 I/WifiService( 990): WifiService starting up with Wi-Fi [B]disabled[/B]
Suggestions:
Since this now looks like a ROM problem (ie. not HW):
1. See this thread. Run the script to disable Airplane Mode which might be causing your problem. If that doesn't work, try step 2:
2. Boot into CWM and then a) Format /cache and b) Repartition the Internal SD card (take the external one out first).
You'll lose all your current apps and data with this step, essentially reverting to a "fresh" install of your ROM.
Re-setup WiFi, time & date and other things again.
If step 2. doesn't work, report back next year, and I'll give you more commands to run then.

Negative. Ran the airplane fix script, nothing. Reset cache/re-partitioned, still nothing. It's still endlessly scanning/shutting off/scanning.

OK. Not one of the common simple problems, then.

This is puzzling because from your last logs, it doesn't look like the wlan kernel driver was even loaded, so no AP scanning should be possible. A little background will clarify what I mean.
On all the 2.6.32.x kernels for the gTablet, the wlan driver is not compiled into the kernel. Instead, it is built as a separate kernel module which is loaded and unloaded as needed by Android (from the files in /system/lib/hw/wlan/). When the wlan driver is loaded both the kernel (dmesg) and Android (logcat) will show some characteristic messages and until the driver is inserted into the kernel no AP scanning, or other wireless functions, should be possible. And, no wlan driver-related messages in your logs tells me that the driver was likely not loaded. (Also, only after the wlan driver is loaded does it check and initialize the wireless HW. So, only after its been loaded, strictly speaking, can we rule out a HW problem.)
Sometimes the Android logs are not complete, so I want to you setup ADB on your PC, enable USB debugging on the gTablet (Setting > Applications > Development) and collect the Android logs like this from now on:
1. Power off gTab; attach the USB cable to it.
2. Open a CMD.exe window on the PC, then run this command (and keep the window minimized):
Code:
C:\> [B]adb logcat -v time > logcat.txt[/B]
After all the tests/commands have been done, restore this window and press Ctrl-C to kill ADB and terminate Android log collection.
3. Power on the gTablet. The ADB command will wait for the gTablet and keep collecting logs on the PC.
Post also the output of these commands:
Code:
C:\> [B]adb shell dmesg > dmesg.txt[/B]
C:\> [B]adb shell lsmod > lsmod.txt[/B]
C:\> [B]adb shell "cd /; find system -type f -print0 | xargs -0 sha1sum" > sha1sum.txt[/B]
Is this the ROM you currently have?
Have you applied the VEGAn 1.00 beta 5.1.1 supplement also?

That was the current ROM I was using. I had not applied the supplement yet, but now I have. Still the same issue. Here are the logs.

In this one I can see the kernel WiFi driver being loaded, and the driver is not reporting any HW chip, SDIO bus, or other errors:
Code:
<4>[ 23.485281] sdio_reset_comm():

As far as the kernel driver is concrned, everything looks OK, but the Android logs still don't show any SSID associations.
What're the exact outputs of these commands? (You can post a screenshot. Mask the psk= value from the 1st output, if present)

See attached. Ignore my syntax errors that I underlined. I was typing wlan instead of wlan0.

Those are OK since you've corrected them. But, these commands you'll have to redo:
1. In the first command (fgrep ... | tr), you've typed a '/' (forward slash) instead of what I've given in the example, which is a '\' (back-slash) character.
The correct character will remove all those blank lines. But, this is a minor typo compared to:
2. The last 2 commands (wpa_cli scan* ...), which you'll have to redo. This time without the extraneous driver argument (again, see the example)--which turns it into a completely different (and non-existent) command. This is why the output doesn't look like what I've shown.
Instead of typing the commands in manually, select and copy the command lines from the browser and paste them into the shell window.
You might also want to increase the no. of columns that CMD.exe displays: Right-click on the title-bar; choose Properties; select Layout; increase the no. of Columns to, let's say, 150.
3. That dmesg.txt file is not very useful because you've not rebooted the tablet before issuing that command.
The kernel has a fixed-size message buffer, so all the HW initialization messages printed only at system boot will be overwritten by later, and irrelevent, messages as time passes. From the timestamps, it looks like your tablet's been on for a couple of weeks, at least--I can't see any of the earlier boot-up messages.
Hi,
The goal of my project is to implement mobile ad-hoc network routing protocol(AODV).
My problem is that I need to reconfigure the wireless driver/adapter to be able to work in ad-hoc mode. This means receiving packets from other nodes and resending packets if 2 nodes which want to communicate are far away from each other.
I don't have experience with drivers changing and I'm noob in Linux.
For better imagination, I've got source code for the Nexus One and HTC Hero and this code should be able to change wireless drivers configuration on these devices.
Here's the code for Nexus One:
Code:
case 0: //NEXSUS
system("insmod /system/lib/modules/bcm4329.ko");
snprintf(cmd, sizeof cmd, "ifconfig eth0 %s netmask 255.255.255.0", ip);
printf("\ncmd: %s\n", cmd);
system(cmd);
system("ifconfig eth0 up");
system("iwconfig eth0 mode ad-hoc");
system("iwconfig eth0 essid nexusbac");
system("iwconfig eth0 channel 6");
system("iwconfig eth0 commit");
break;
And here for the HTC Hero
Code:
system("insmod /system/lib/modules/wlan.ko");
system("wlan_loader -f /system/etc/wifi/Fw1251r1c.bin -e /proc/calibration -i /data/local/bin/tiwlan.ini");
snprintf(cmd, sizeof cmd, "ifconfig tiwlan0 %s netmask 255.255.255.0", ip);
system(cmd);
system("ifconfig tiwlan0 up");
break;
I was wondering if you could give me some advice what commands to use.
My Sony Xperia P is Rooted and I'm using Honami Moonwalker V8 ROM.
It seems that command ifconfig is not working. If I try to execute e.g
Code:
ifconfig eth0 up
android shell throws this error:
ifconfig eth0 up
error: SIOCGIFFLAGS (No such device)
Thank you for your answers. I really appreciate the time you give to this thread.
Try wlan0

thanks ChikeD, it seems that wlan0 works fine for ifconfig but it seems that iwconfig binary is missing. Are there any alternatives for this shell command in Android?
I tried to use iwconfig binary from Android tethering project but using it throws an error like this:
Code:
[email protected]:/ # iwconfig wlan0 essid xperiaP
SET failed on device wlan0; Invalid argument

I just need to make it work in the ad-hoc mode. If think it's an IBSS mode. I just need to figure out, how to setup this type of connection

Assuming(thinking) is not an option.
From a brief look at the sources it seems the ad-hoc is not implemented.

Sorry for delay.
So you don't consider an IBSS mode as a true ad-hoc mode? Am I right? I thought that IBSS is like a synonym of the term "ad-hoc"
According to this website: http://en.kioskea.net/contents/804-wifi-modes-of-operation-802-11-or-wi-fi
It should be the same.
To my problem. I've made this commands to work:
Code:
/*Bring the interface up (an additional step like rfkill unblock wifi might be needed: ip link set wlan0 up*/
system("iw dev wlan0 set type ibss"); //Set the operation mode to ibss ):
system("iw dev wlan0 ibss join MyAdHocNetwork 2412") //frequency for channel 6: 2437, 2412 for channel 1...
system("ip addr add 192.168.1.2/24 broadcast 192.168.1.255 dev wlan0");
system("ip route add default via 192.168.1.1");
What do you think?
Thanks
Seems so, does it work?

I don't know yet. I seems that everything is set up. Now I need to buy at least another xperia p or similar smartphone to test communication.
I am now trying to run ad-hoc mode on HTC Desire and Tablet Prestigio Multipad 3270b. But it's pain, because they don't have iwconfig and iw binaries.

Doesn't have to be a smartphone, you can do it with a wireless pc/laptop

Thanks for the links. The goal of my project is to run ad-hoc mode on android. I will definitely test this later using windows but I am running out of time, so I'm focusing mainly to at least changing wireless mode from managed to ad-hoc. That's the most difficult thing because right now I am not able to change wireless mode on HTC and Prestigio using linux system commands. Maybe there is a way to change wireless mode programmatically (Java or C) but I haven't found that information yet.
