[Q] Tethering issue - Android Q&A, Help & Troubleshooting

Apologies if this has been asked before, but I've searched and couldn't find anything that matches what I'm after.
I have a GNex running custom 4.2.2 and Windows 7 x64.
I want to be able to access my phone from my PC. To do this, I installed AirDroid. All good so far.
Issue 1: Using WiFi to access the phone, it doesn't do anything when the screen is off/the device is locked. Annoying.
Issue 2: Using USB tethering, it works fine when the screen is off, but kills my PC's internet access. Also annoying.
I would like to use USB tethering if possible, but I only want to be able to access my phone via AirDroid, not use it for internet (my PC has a much better wired connection already).
More on issue 2: Windows says the DNS server is unavailable when I troubleshoot. The moment I plug in my phone and the NDIS-thingy connection is formed, I lose internet access via my normal connection. It goes back to normal as soon as I unplug it. I've tried changing the priority of the network devices, but to no avail.
Any help appreciated.

Solved my own problem.
To those who are curious:
Under network settings for the USB tether, set DNS server addresses manually, go into advanced settings, and set the default gateway to whatever your router's address is.

[Q] WiFi router on XP netbook not working

Hi!
I recently began using a netbook with Win XP on it and sadly it cannot connect to my HD2 set up as WiFi router. I can select it from the wireless networks list, it shows that it is an ad hoc network and asks for a key - but when I hit connect... the progressbar keeps running and running until I abort the attempt.
XP has all the latest updates, I updated the wireless driver to the latest, I tried it with disabled firewall... I even pre set the network manually (computer to computer, WEP and Key) nothing helps.
At the same time a Vista laptop can connect to the HD2 router just fine.
Any ideas? I'm out of them... And frankly I'm already sick of connecting my devices via cable to get online when my HD2 has this nice and otherwise working feature.
Solved... in a way.
When I activate the option in Wifi-settings that forces my computer to only connect to computer to computer networks it works fine. Maybe the connection to the HD2 takes too long to be established or the importance ranking of available regular WiFi networks is too high in the default settings.
But it is quite bothersome to change this setting everytime I want to change the connection type from computer to computer over to regular and vice versa. Does anyone know a way to nullify the network preference without blocking either of network types from being used?
This is how it is now:
When it is set to accept only computer to computer networks I can use my HD2 as WiFi hotspot but am blocked from using any regular hotspot and get a windows error message when I try so.
When I set it to allow all network types and try to connect to my HD2 I get stuck with a connecting messagebox with an ever ongoing progress bar - but I get no error message.
When a known regular network is in range Windows even connects with that, although the connection attempt messagebox is still there. Doesn't make any difference though if a known network is in reach or not. It doesn't connect to my HD2 either way.
I just want it to work without having to make adjustments every time
It is a huge security risk to do this but look here and check the "Connect to any" box.
That's exactly what I did... See above.
But thanks for the lookup!

[Q] connected to wlan but no internet access

Hi Folks,
I have an issue with internet access with my Archos 70IT(H) (rooted FW 2.3.81 +rw). I recently moved into another flat-share and wanted to access the wlan there.
the network set up fond the network in question - no issues. the pw was accepted as well. finally the connection was established - so far so good.
Then I tried to connect the internet - noting. non of the internet applications worked. The network connection was still active (at least the sign indicated this). I tried to reboot - same issue.
now the funny bit: I tried another network - my archos worked fine. and I had no issues before.
I went back to the network I have trouble with and established the wlan connection with my laptop - no problems at all. click - done.
I have absolutely no idea what it is. Obviously it looks like an issue with the rooter but what can it be? the laptop connected without any problems? The only idea I have right now is a firewall is blocking the access of my archos.
Does anyone know what ports does the Archos use to connect to the internet (I would assume the same as a laptop, but...)?
What else could it be? Anyone any idea?
Thanks in advance!!!!!!!!!!

[Q] Using phone as wifi router with wifi signal

Alright, did the usual searches and have the usual answers wich don't seem to pertain to what i'm doing.
I have one static connection allowed to wifi router. I wish to use phone to share this connection with more than one device not using mobile data but the broadband connection.
Basically connect phone to broadband wifi. Have devices connect to phone to share wifi.
Again, to prevent any confusion: I do not want to share mobile connection on phone. I wish to share wifi connection with other devices from phone. ie. I have only one connection allowed to router and I wish to use phone to share that connection with PC and PS3.
Sorry for redundancy in stating this but people seem to miss the point or not read and suggest applications like Barnacle wich only share mobile internet or USB tethering wich only works for PC.
Well from what I understand Wi-Fi must be off on phone in order to create the Wi-Fi signal on the phone so this may be impossible
Sent from... somewhere...
I know exactly what you are saying, and I am pretty sure it is impossible. I currently have wi-fi service where I have to log in, with only 1 device allowed log in at a time. When you turn on the wi-fi hotspot on your phone, it automatically turns your wi-fi off. You can only use the hotspot feature using your data connection over 3g or 4g. I have tried everything. If you are in the same situation, where you can only log one device on the internet connection, you may want to try spoofing your IP. Change the IP on the other devices to the IP on your phone. This may allow you to log the other devices in as well (so I have read). That may be your only option.
Yeah looks like Im going to connect PC and use an ethernet cable with connection sharing to get PS3 to work. Phone will have to use mobile data unless PC and PS3 arent being used.
Or phone gets wifi and USB tethered to pc and then connection shared (not sure this will work).
sharing wifi connection
I have done this using a Buffalo WLI-TX4-G54HP ethernet converter. You connect to the wireless source (WAP) then it acts like a router and allows you to plug devices into it, has four ports but you could use a switch if more are needed. Each device aquires an IP from the converter and is hidden to the WAP, looks like one device is connected. Pretty easy to setup. Check it out.

[Q] Adhoc on YP-G70 using a custom ROM with 2.3.6

I have a YP-G70 (galaxy player 5.0), international version. It came with gingerbread 2.3.5, and it was unable to find the adhoc network I've set up in my laptop.
Then I flashed it with rumirand's custom kernel r13 and Meticulus's Foreigner ROM R5.1 (GB 2.3.6), and the problem was still there.
Then I replaced the wpa_supplicant file with the one mentioned in these posts:
http://forum.xda-developers.com/showpost.php?p=22268045&postcount=60
http://forum.xda-developers.com/showthread.php?t=1438334
http://forum.xda-developers.com/showthread.php?t=1377321
(the file that is mentioned is always the same)
Now it detects the adhoc network, but when I connect to it, the wifi status starts looping: connecting -> disconnected -> scanning -> connecting -> disconnected -> ...
Did I miss anything?
Has anyone managed to get adhoc to work on YP-G70 using one of the custom ROMs based on 2.3.6?
Or do I really need to go back to 2.3.5 and use the wpa_supplicant file mentioned above?
Thank you
I have played with some of these wpa_supplicant files recently. The result seems to be hit and miss.
So far I tried connecting to 2 different usb wifi dongo using ad hoc mode. The only successful one is the ad hoc connection to a tp-link wifi dongo using wep mode. This dongo doesn't support wpa.
The other one that failed is a linksys dual band dongo, I can't get a connection with either wep or wpa. The observation is very similar to yours.
Need to try a few other device to see what's wrong or whether it is due to incompatibilities.
By the way, I also tried all the possible security options (open, wep, wpa). Same behavior for all of them, except that the "connecting" step took much longer when using wpa.
Interesting note on incompatibilities. My laptop's wi-fi card is an Intel PRO/Wireless 3945ABG.
I found out that it ends up connecting successfully if I just leave it looping for a while... sometimes it will succeed on the first few attempts, sometimes it takes several minutes.
So far, it only worked in open or WEP. Never got it to work in WPA.
DHCP
Have you tried to use a fixed ip instead of dhcp ?
Yes, that's how I've always had it set up. I don't think there is a way to use dhcp in ad hoc.
Today, I've switched to the Chip v1.5 custom firmware and I just can't get ad-hoc to work at all. No ad-hoc networks are displayed in the wifi settings.
I've tried replacing the wpa_supplicant file with different versions of that file, but it just rendered the wifi completely unfunctional: I turn it on, it goes "scanning...", then it turns itself off automatically after a few seconds. I had to reinstall the firmware in order to get the wifi to work again.
I would really appreciate some help, as I completely rely on an ad-hoc connection to obtain internet access on my SGP when I'm at home. I don't feel like going back to the firmware I was using before, having seen how great this one is.
So you have used static ip? And set it up correctly? Because the wifi connect and disconnect problem is frequent with belkin routers, and is fixed by using static ip usually.
Sent from my YP-G1 using xda app-developers app
Yeah, the IP settings are correct, and I'm using a static IP. I eventually got used to the looping that I mentioned in a post above, and I've lived with that for the past 8 months.
However, as I said in my previous post, I've installed the Chip v1.5 firmware, and now my problem is somewhat different.

if you had this happening, it meant the wpa_supplicant you'd tried wasn't compatible with your device. Always backup wpa_supplicant before replacing in in case the new one doesn't work.
Try this wpa_supplicant, it works with my 5.0.
I had the same problem with Ad-hoc networks using windows7 (ie obtaining ip address loop) - I gave up in the end, but found this : Windows 7 as a WAP. It does the same thing, only it's not an ad-hoc network - you can also share wifi internet through the same wifi adapter...it works great for me!

I did backup. But, even after putting the original wpa_supplicant back in, wi-fi was still broken. So, the only way for me to fix it was to reinstall the firmware.

Thanks. I've been playing with that wpa_supplicant for a while now. However, it did not solve the problem.
It detects the ad-hoc network that I set up on my laptop, but I'm having a hard time trying to connect to it. So far, I've only been able to connect twice. What I need to do in order to connect successfully is to keep enabling and disabling wi-fi. Each time I enable it, it will automatically attempt to connect to the ad-hoc network (because it remembers the info). Most of the time, it will say "Connected", but it actually isn't connected. It only succeeds like once every 50 attempts. And even if it succeeds, it will disconnect automatically after like 10 seconds. At least it gave me enough time to test the internet connectivity, which worked fine during those few seconds. Changing the encryption type from WEP to WPA only made things worse.

That seems like a great idea. However, my laptop's wireless adapter (Intel PRO/Wireless 3945ABG) does not support that functionality. An adapter with Windows 7 certified drivers is required. I also tried to use Connectify, but it also does not support this adapter.

that's very strange. This wpa_supplicant works on my GP 5.0 very well. It detects my WEP ad-hoc network and connects to it just fine and keeps connection until i disconnect. Sometimes it won't connect right away, in which case i just turn wi-fi off and then on again and then it finds the connection, connects and then everything's fine.

Agghh that's a shame.... you could try buying a wifi dongle.. they're not all that expensive...
After playing a bit with the network adapter settings on the laptop, I am now able to connect successfully to the ad-hoc network as soon as I enable wi-fi. What I did was changing the property "Ad Hoc Channel 802.11b/g" to 1 (it was 11 before). Setting this property to anything other than 1 makes it not be able to connect.
There is still the issue of automatically disconnecting after a while (which can vary from seconds to minutes), but it doesn't happen very often, and I'm usually able to stay connected for a long time. Playing with the network adapter properties didn't seem to help in this regard. Anyway, I guess that the problem is solved.
It should be noted that I've never had to change the network adapter settings for any anything else before. I've always been able to connect to other computers via an ad-hoc network. I also used to be able to connect with my SGP 5.0 when I had a different ROM installed. The looping problem that I had before (see my early posts in this thread) could probably be solved also by changing that property in the adapter.

How did you get to that property? I can't find anything similar on mine...
Control Panel -> Network and Sharing Center -> Change adapter settings -> Right-click on the wireless adapter -> Properties -> Configure... -> Advanced.
The properties for the network adapter are listed there, and you should be able to change them.

Hmmm yes, I looked there but unfortunately there is no option to change or configure the channel at all!
I suppose it's driver dependent.

[SOLVED] Galaxy Ace connected to Wi-Fi but no internet.

Well, the title says pretty much all .. I earlier didn't have this problem.. Then since last night, I came back home and connected my Galaxy Ace to my home wifi, but this time, it wasn't transferring any data.. It would be connected, full signal, but no internet connection.. My browser, gmail, YouTube, PlayStore, nothing would load.. It'd keep saying Connection Error. Retry.
My wifi works properly on the computer and other devices, and my phone used to work perfectly too! Why's it suddenly giving this problem?!
Any solutions!?
SOLVED!
Okay so I figured it out on my own!!
I went to Wifi Settings>> Advanced>> and "Use Static IP"
I then provided my phone with an IP address, gave the DNS servers as mentioned by my Router, and gateway, is ofcourse, the IP adress of the router. NETMASK is Subnet mask ..
Once I filled in them correctly, and as per my router settings, my mobile is now transferring data and I can now access the internet!
Just thought I'd post a reply incase anyone else was facing this problem
No data through laptop hotspot.
I have a similar problem, but with using my laptop as an access point. My Samsung Galaxy Ace had no problem connecting to either my or my wife's laptop access points initially till about a week ago. I use an HP while my wife uses a DELL. We both run Windows 7. But, here's when things started to get strange.
1. The Ace even though connected through my laptop's AP Wi-fi cannot send or receive data after the first few seconds.
2. My wife's Dell XCD35 (ZTE Blade) has no problems.
3. The Ace has no problem connecting to an Android AP or my wife's laptop AP.
I reflash and unrooted my phone and basically brought it back to factory settings but no luck.
Tried using other services for using my laptop as an accesspoint - mhotspot, virtual router and connectify - still no luck.
tried static ip - no luck.
reinstalled the MS Virtual Wi-fi Miniport Adaptop driver - no luck.
Somehow, there is a security setting on the laptop that's preventing my phone from connecting to the internet. I think I maybe connected to the network, but access to the internet is restricted.
There are no other features like MAC address binding or anything like for laptop APs.
It's getting really frustrating now.
Any help would be appreciated.

Set your Internet to "Allow other computers to share this Internet connection". Other ideas would be to check/disable your firewall
Wifi connected but not working
My Galaxy ace plus connects fine to wifi network but cannot browse internet or play store. I am using a free public wifi so i dont know about the static ip address. And this problem was from the starting whn i just bought it. So is there any other solution for this problem or not?
I tried everything... I restarted the modem- no luck. I filled in the blank from the advance wifi setting- no luck
