Tethering WiFi - myTouch 4G General

This is something I discovered, which may already be known (i couldn't find anything), which I hope may be able to help someone as much as it helped me.
If I'm connected to WIFI on my phone and I USB tether to my computer, my computer gets the speedy and strong WIFI connection.
If you're wondering why I would go through that and not just directly connect my laptop to the WIFI, well it's because the piece I put together doesn't have all the proper drivers (and I probably broke something) so I cant even turn WIFI on, let alone connect to it.
Whatever your situation may be, I hope someone else finds this useful.

Help with internet since flashing

Hi all,
I try not to post too often, and just do a lot of reading and studying and learning.
Anyway, I am running MrFrazz's WM6aR2, and having an issue with active sync and my laptop. Everytime I try to connect to any wireless internet while active sync is running, I lose the connection and can not recover it. It runs fine if I have not hooked up the phone. Once I connect, thats it, and I have to reboot the computer to get it back. I just reflashed some other ROM's on my phone playing around, and did not like them, so I went back. Now it is doing this. Anyone out there think they canhelp me figure this one out?
On your computer go to the activesync app, click on file and then on connection settings and then check the box that says allow wireless connection on device when connected to the desktop.
It still does it even then. I have tried adjusting all of the setting. I am pretty computer competant, and dabble in programming, but this one has me stumped. Anything else I may be missing??
I think I miss read what your actual problem is. Is your phone losing it's wireless connection or is your laptop losing it? If your laptops the one that's losing its wireless connection then it sounds like it's having problem running 2 connections at once. This is just a shot in the dark and probably won't help at all, but try making your connection to you phone a static connection and leave your wifi connection dynamic or vice versa and see if that helps. If not, maybe deleting both of the connections and letting your laptop reinstall the connections might help. Like I said, both suggestions are just a shot in the dark, but there shouldn't be any reason that it wouldn't use both connections at the same time that I can think of unless it's trying to assign the same ip address to both connections but they shouldn't even be in the same range.

Wifi problems

Hi,
Could anyone tell me what's the rationale behind this:
When the device connects to the internet via 3G in order to receive mail or whatever, it will just stay connected until you bother to manually disconnect it. But when using wifi, which unlike 3G doesn't cost by the byte, it will disconnect as soon as the screen goes off?
Why on earth is that? Instead of running the hell away from cellular internet as soon as possible it does so with the free wifi? Is there any way to change this behavior? Or am I the only one who's bothered by this?
Besides that, more often than not, I'm having problems connecting to wifi... sometimes it would attempt to connect to a network and then give up and say it's unavailable (even though the signal is excellent and I'm right by the AP). other times, it appears connected but there's no internet... anyone else has these problems? Is my device defective?
Sorry if I'm ranting...
Thanks!
I think the behaviour is to save energy. When the screen goes off, the device "thinks" you don't use it anymore. Wifi drains your battery very fast, so the phone tries to reduce it.
For 3G it's the point, that there isn't much data transfer in order to stay connected. Maybe a few kb for the whole day (I don't know if there is any data transfer anyway, but when it's verly little). That's much cheaper than to pay for the full block (for example 100kb) everytime you disconnect. So staying connected saves money in most cases. That's why.
Connection problems: Do you use any encryption? Maybe that's the problem. So far I use wifi only for data transfers between my Macbook and the device. But I don't have any problems.
If you search hard enough you can find apps that might jus tkeep it on.
One such app is KaiserTweak which will keep that wifi on when screen goes off. problem with kaisertweak is that i have heard it can hard reset some peoples devvices, depending on what options you select.
i might give it a whirl because i hate it when my connection is lost, i end up using my data connection when i dont need to as it tries to take over when device wakes up!
edit: seems ok so far no hardreset yet!
Thanks, will try that.
I flashed a 6.1 rom and it seems to have made an improvement. Now it would connect fine to my home router every time and not just occasionally (it uses the most basic wep encryption). Still no luck at work though... just as before it appears connected but I can't reach anything inside or outside the lan. The encryption there is the more secure wpa-psk and there's no mac filtering.
Anyone successfully connected to a wpa wlan?

"Wireless Tether for Root Users" app won't stay connected

Does anyone else have this problem?
My laptop will stay connected for a maybe a minute at a time, sometimes just a few seconds and I have to reconnect. Under Wireless Network Connection, the network is listed as "On Demand", if that helps.
I've tried every version of "Wireless Tether for Root Users" I can find and they all have the same problem. Is there anyway to stay connected?
Is it possible that your computer won't let you connect to an Ad-hoc connection? Maybe as soon as it realizes what it's connecting to it jumps off?
Havent had a problem, are you using the administration portion of wireless thether, you might have to just confirm the connection on the phone and apply the settings, you should have a green sheild when on your phone when a allowed device is connected
As far as I know ad hoc networks are allowed, I am using windows xp.
I have access control on and my laptop is allowed and connects fine, it just will not stay connected.
I am using a Toshiba nb205 netbook with windows xp.
On the Choose a Wireless Network window, next to G1Tether it says "On Demand" instead of Manual or Automatic. I've never seen that before.
I'm using the internet fine, I just have to reconnect every 30 seconds or so. Perhaps my google skills are too weak, but I cannot find anything, any help is very much appreciated.
Can you connect to a wifi network from the phone and stay connected?
Can you connect to a wifi network from the laptop and stay conencted?
"On Demand" is normal for Ad-Hoc Networks.
I had the same problem after upgrading from fresh 1.0 to 1.1 w/ gk-31. I uninstalled wireless tether and reinstalled it from my mybackup pro app backup (the one I made before flashing the new Rom and kernel. Works just fine now.
If I'm not mistaken I believe flipz included a newer version of wireless tether, maybe the old one works better.
I just realized I assumed you are using freshrom...
Might try reinstalling it anyways, let us know how it works out.
Reinstalling didn't work. I'll try out some roms tonight and see if they work any better, thanks anyways
Old post I know, but just wanted to see if anyone had any more ideas here. I don't think it's an android app issue at all, but rather windows. I'll be cruising along the highway with a fine connection, but as soon as windows picks up a random access point, it will jump off my ad-hoc connection and try to connect to the other one. not cool.

[Q] Fix 3.2 Bluetooth-Tether issue?

Hi!
Since Honeycomb 3.2 there is an issue with bluetooth tethering. The first time it works, but after disconnecting you won't be able to reconnect until you have rebooted the Xoom!
That's absolutely annoying... And I think at least for root-users (like me) there should be another way.
I couldn't find any fix on the internet. But I think it should be possible to maybe reload the bluetooth kernel module or something. Maybe it's mobule bcm4329? Does anyone know how to do that (modprobe doesn't work).
Or are there any other ideas?

My bluetooth connection wasnt reliable with bluetooth tethering either. I found though that when i did tether id only use the connection for like 30 minutes at most. If thats the case you should update to the latest version of wifi tethering from google v3.1 beta. Because when you tether wifi with that it tethers in infrastructure mode instead of ad-hoc that way your xoom can see it and connect with no problem. its completely reliable for me. And works flawlessly. ive had countless issues using bluetooth (Almost never was able to connect to network. only able to be paired)
if you do go that route. After connecting your xoom, make sure you have access control checked and that your device is in the list and enabled in wifi tethering then save.
Generally WiFi-Tether is no problem. I'm accessing the internet through my HTC with CM7 and Gingerbread offers WiFi-Hotspot by stock. But the point is, that this really drains your phone's battery if you just leave it connected.
Using Bluetooth-Tethering with the root-app Wireless Tether installed on my phone, the battery lasts much longer. Of course the connection is slower, but for mails etc. that doesn't matter. With Honeycomb 3.1 it worked great, but since 3.2 it simply won't reconnect until you reboot... You can even unpair and repair the devices etc., it doesn't help. After rebooting the Xoom it connect like a charm...
I think there has to be a way to just restart the bluetooth-module or something... But I don't know how.
Hey guys,
is there no one out there, who can help? If you search the internet, you find a lot of people, who are having this problem - no one even has a workaround.
The fact is, during reboot all the services and kernel-modules are reloaded (of course). So if s.o. could just say which service/module is responsible for bluetooth-tethering and how to restart/reload it without a reboot, this could already be very helpful!
I have an idea!
OK, I'm a little stuck, but I've got new information.
Obviously it's a DHCP-issue. Seems like the DHCP-client on the Xoom doesn't pick up a new IP anymore... If you type netcfg in a terminal emulator, you'll find that.
With su dhcpcd you often can push it get an IP! Then, after that, you sometimes can connect several times without problems, but connecting to WiFi again can be problematic...
Any ideas? Is there another way to make the dhcp-client get an IP?
My idea is to set up a static IP for that interface bnep0, but I can't find the proper config-file... Can someone tell me how to set up a static IP only for that single interface?
i am running wireless tether 2.08 which has Bluetooth wifi built in and I also have the same issues. Hopefully someone will come up with a fix for this. I kind of prefer running my Evo with Bluetooth than wifi since it does not run hot
No one has found a fix, yet?

[Q] Can we use P920(H) as a modem for a 3G router?

Hello all. I've just purchased a 3G/WAN WI-FI router (TP-Link model TL-MR3420 - link to manufacturer's page). It has an USB port to connect a 3G/4G modem. I tried to connect my P920H (V28b stock ICS - XBSA large partitions) but the router doesn't recognise it. I tried to use an older 3G phone (Sony Ericsson W980) and it works like a charm. In both cases I configured the phones to USB tether with their own configuration options.
Anyone managed to make this work? I believe the router lacks a driver, but I've found no driver for any phone on the manufacturer's page, although I works with the Walkman phone.
Edit: I forgot to mention that all tethering features on my phone works fine. I can turn on my hotspot and I can plug it to a PC's USB port and act like a modem. I just can't do it with my router.
Why I want to do this: Most of you who have nice broadband access may be wondering why I want to use my phone to provide Internet access to my router. Here's why: In the region I live, broadband access is a joke. A miserable 1Mbps insufficcient to watch even the lamest youtube video. But it has no limitations, so it is good for TV upgrades and other connected devices to do their maintenance.
On the other hand, my phone provider has a wonderful coverage around my house, sustaining an average of 3Mbps, reaching 10Mbps late at night. So, when I want a quicker net, like to watch Internet movies or download large files, I used to turn off my router and turn on the phone's hotspot. But even setting its SSID and password identical to the ones on the router, it takes some tweaking on the devices for them to reconnect. It was a nuisance.
With this 3G router, all I would have to do is connect the phone to it and it would switch from WAN to 3G. All I need is a driver that would make it recognize the phone and use it as a modem.
I messed with wifi tethering a bit a while back. Couldn't get it to work. My other phone sees it as a wifi point but won't connect. Something to do with LG not liking tethering I heard. I saw this mod that fixes tethering for some devices but never tried it ( I don't really need tethering). I am curious if it fixes it:

Hello drastic00!
Thank you for your suggestion. I understand that the mod you suggested can have nice effects on slow or even broken tethering.
The problem is that I haven't made myself clear on the first post. I can see it now and I'll edit it right away. The tethering feature on my phone works fine, both WI-FI and USB tethering works. What I need is a USB tethering that makes my router "think" that my phone is actually a 3G USB modem. When I use this feature on a PC, I have to install the drivers. The bad news is that I can't install these drivers on the router.
Okay. I figured if wifi tether isn't working then usb isn't either. So what firmware do you have on which it is working?
There was a small discussion on a thread a month or so ago; it wasn't working for the 4 or so people who posted then...I think we were all on ICS or higher, but not positive. That's when I tried to see if I could get wifi tether to work. I didn't try any usb tethering.
So I guess I am not understanding the advantage of plugging direct to the router. Why not plug the phone to pc (signal in) and the router to pc (signal out)? Because it would be easier to switch from the signal you normally use? This is a new one on me... I have no idea if an ethernet switch would be of use...2 signals in for the router to broadcast and choose which wifi signal on the client end (not sure if your router could do that, just grasping at straws, since I haven't tried anything like this).
It's weird other phones work though, so I am still curious if Crossbreeder mod would do anything. It seems the other phones have a piece of software the O3D does not. Unless the router has drivers installed for those devices by default, which I doubt; you didn't install anything for those to work, they worked out-of-the-box, so to speak, right?
Exactly. Both WIFI and USB tether always worked out of the box for me, with several ROMs, either stock and modded ROMs. Eventualy some modded ROMs did break tether, but usually broke many other things as well Probably too undervolt and/or too overclock among other things I don´t understand.
I remember that discussion about not working tether, but didn´t get involved. It never happened to me. I believe it is more a hardware issue. If it happened to me, the first thing I would do is install the original stock Froyo to be sure if tether didn´t work with the most original firmware.
As to why I want to put my O3D as the Internet provider for my network: I have several devices connected: 3 PCs, 2 Androids, 1 TV and 1 Blu-ray player. The last two are not too easy to make connect to a different WIFI net, even if they have the same SSID and passwords. I used to turn off the router and then turning on the phone´s hotspot. The problem is that almost always several of these devices didn´t realise the switch and kept trying to connect to the unavailable router. The same thing happend when switching from the phone to the router.
Also, I don´t want to buy a 3G modem, because the speed advantage (and low fees) are "connected" to my voice plan. The SIM card is my primary phone number So, I need it to be able to make and receive calls. If I purchase a new SIM card, I would have to cope with two bills. Again, no more advantages.
Breaking news: I just noticed that the Sony Ericsson Walkman phone I am using as a modem only gets 1Mbps download, exactly the speed my provider guarantees. My P920H can get more than 10 Mbps on times, but usually between 3 and 5 Mbps. I believe that V28b stock ICS somehow unlocks some sort of ISP speed limit. Now, more than ever I want to use my phone as a modem on my router.
