Found better batterystats for gb spare parts equiv... only saw the market one yesterday. Nm about question2.
Any help is always appreicated.

Any love on the question of better wifi management?

I've looked into this. The answer is no. The reason why is most devices including laptops are set for us consumers to get the furtherest range on wifi ap's. Now laptops atleast have an option in the connection properties of your ap called roaming its default option hangs on to wifi as long as possible then there is aggressive which will change the ap its connected very fast but I have not seen any app that will let you make a "wifi roaming" setting change. I believe its kernel level with our device.

Tethering app success since there is no root

What are people using for tethering since root isn't available yet?
Ive used the method described in the following thread. The best part about how it works is that it offers infrastructure mode, so I can tether my Galaxy Tab without any problems.
http://forum.xda-developers.com/showthread.php?t=1079340
Note: See post #6
I heard that doing the ##778 edit causes a loss of phone data while tethered to the PC. Meaning data on the phone is dead but the pc has data. Is this true? After the edit do you just use the stock 3g mobile hotspot app?
Yes it's true, I've tried it.

But do you lose data on the phone while tethering? Also do you use the stock vzw app?
The answer to both questions is yes. I actually hadn't noticed it before but on my Dinc2 the signal meter only shows 1X instead of 3G when I activate the hotspot option. I guess I don't find that all too terrible as the only time I'm tethered I'm either using my tablet or my laptop.
Once the change is made, the hotspot app functions like it would if you were subscribed to the service.
What why would you do the hack if you only get 1x when tethering, that would be crazy slow.
Oops, My mistake. It appears my earlier reply was a load of crap!
3G is still clearly visible with hotspot enabled. Just ran a speed test on my Galaxy Tab. Downloads ranged from 473-329kbps with uploads between 303-193kbps.
So just to clarify. You did the following edits.
-in edit mode you will open 'security' and 'm.ip default profile' in turn. each time you look for the only entry containing "dun", as in:
<your actual phone number>@dun.vzw3g.com
edit out the "dun." so it looks like
<your actual phone number>@vzw3g.com
And you then use the stock 3g mobile hotspot app. After you enable the hotspot can you browse using the phone also? Or does internet on the phone stop working.
I think you're right, clarification is certainly in order.
Yes I simply removed dun from both of those locations and now use the standard, VZW included, hotspot app.
The phone cannot access the internet while tethering is enabled. Certainly a sacrifice, but from what I've seen so are the apps available with a rooted device which from my understanding cannot create an infrastructure hotspot, only ad-hoc.
Yeah the phone data loss kinda is a downfall. But I have an infrastructure connection with wireless tether on incredible 1 just for your info. Some apps are lucky and give good connections. well loss of data is probably a sacrifice I will make. thanks
Seems to me that the only time this would really matter is if you're sharing your connection with friends while still using your phone for data. Is there something I'm missing? I can see it being a minor annoyance but something I'd personally never run into.
Just so you know...

If the detection is at the app level (unauthorized), like the article suggests, the hack may still be under the radar for the time being since folks are probably using the authorized app pre-installed on their phone.

[Q] Wireless Tether Access ControlQuestion

Just a random question. I am using the wireless tether app, with the access control enabled. I notice, that there is another connection always asking for permission. The mac address is 00:00:48:"somethin", and the name of the computer is "*". All it is is *. Any idea what this can be? it certainly isnt any of my computers.
Is it always there when your in the same spot or everywhere you go?
Sent from my PC36100 using XDA Premium App
Most likely someone else trying to get on; they have to have permission before they get data.
I havent tried it in other spots, I am currently using it for my internet until my cable company arrives to install broadband. (yeah, sorry, im hogging the network, but I have no choice for now). The few other places I have tried it at, it doesnt come up. It only comes up every now and then. But yeah, I have only noticed it at my place. And it randomly shows up.
Yea, but don't they have to have the wpa passphrase to get connected in the first place?
Yea they need code to be connected. Don't trust anything you don't know. It's a risk. Imo

[GUIDE] (Free) Mobile Hotspot aka Wifi Tethering

I believe there may be some noobs on XDA, like myself, who did not know how to set up wifi tethering after root. Here's a quick rundown.
1. ROOT your phone (http://forum.xda-developers.com/showthread.php?t=1756885)
2. Go to Playstore and download "Wifi tether for ROOT users" (****EXCEPTION BELOW)
3. IMPORTANT!!! go to the app's setting and set the "Change Device Profile" to "GENERIC ICS"
4. there is no step 4.
Save yourself some $$$ instead of paying Verizon a service that should have been free to start off with. :victory:
EDIT: **** buhohitr mentions that you can achieve wifi tethering WITHOUT ROOT through the playstore app "FoxFi"
ENJOY!!!!!

Well... I figured it'll get the most views in the development section so here it is. One thing I might change is getting this in the "Guide" category
Just a note: I've been using this app with really inconsistent results using generic ics profile and auto setup. I've only been able to detect the wifi twice. I read somewhere that turning wifi tether on, let it start up, turn it off, reboot phone, and start up tethering again works somehow. I just tried it and it worked right away but this is only once. I don't know if this will work consistently 100% of the time though
best wifi tethering is just down load Foxfi from the market, installed and bang work like a champ..very reliable.Foxfi work with root and without root.
Thanks, that was a lot easier than I'm used to. Wifi tether worked the first time, and I turned it off and on a few times and it worked everytime.

This is the correct way to do it. choose "galaxy nexus for CDMA/LTE"
also, do not forget to check "routing fix"
this will give you full infrastructure tethering instead of ad-hoc tethering.
what does this mean? It means that your phone will allow things like ipod's , game systems (psp, gameboy..) to connect as well. It will function exactly like a wifi router.
cheers
This could just go in the themes and apps forum technically since all you're doing is installing an app basically... But I guess it's a guide. Thanks for the info OP. For those of you on the new shared data plans, don't even worry about following this guide, the tethering is included in the package because Verizon wants you to use more data and pay overages.
The default tethering app however does support open NAT for Xbox and PSN though which is kinda nice :X (Only wireless tethering root app I got to work with PSN and Xbox for open NAT is barnacle WiFi tether and it was a bit of a pain the butt.)
Free Hotspot on Shared Plan
If you purchased the phone with Verizon After the deadline and lost your unlimited data however, gaining a shared plan, Wifi Hotspot is included in the share data plan at no additional cost. There is no reason to hide your wifi traffic. HOWEVER, I personally find the Wifi Tether app to be better than the default Hotspot app anyway.

You must have meant that this is the correct way for you. When I check "routing fix" or "galaxy nexus CDMA/LTE", my laptop connot see a wifi signal. However, following the OP's post worked like a charm for me. Obviously, it may take a bit of tinkering for people to determine the best setup for themselves.
Is there a way to lower the power of the Wifi from the phone to save power. The range you get when tethering is way further than necessary and it might be better for battery if you could lower the power usage.
Also, is using this rooted wifi tether safer than using foxfi in terms of verizon detecting the use.
How safe are these methods compared to using a power toggle widget to just enable the built-in tethering app? I've found if you try to enable it from the menu, it checks for subscription, but if you use a power toggle app, it "just works."
Edit: One more question....while performing the Wifi pop-up hack, I found an option along the lines of TETHER_ALWAYS_ON. Has anyone tried changing this to a 1?
I believe tethering is more frowned upon than anything else by verizon. I have not heard otherwise, or heard of trouble with big red because of it. However, the "best customer experience" is had when you pay for it. Haha.
Been using Foxfi the last couple of days with no problems. Solid app that works well.
That worked for me, thank u sir

Home WiFi not working on E4GT

I obviously have the Sprint S2, and I continue to have issues staying connected to my home wifi. I have no problems connecting to other wifi networks. It will connect, then after a few minutes, it disconnects, even though it shows I'm still connected in my notification bar. I've searched high and low. It seems many other people are having the same issue, but no one seems to have a fix. Anyone here know of a solution? Thanks in advance.

So I finally figured out what the issue was. A lot of mobile devices have a hard time connecting to highly secured networks such as wpa2. If you have a wpa, or wpa2 protected router, you can only use numbered passwords. Up to 10 characters. I tried this, and it's the only solution I found. If that still doesn't work, change your wpa2 security to wpa, with a numbered password only.

if you have to use numbers and only 10 chars, it sounds like a router config issue. sounds like you have WEP on rather than WPAx
Wifi busted
I actually have the same issue. Wifi worked flawlessly on gb. On ics every time phone goes to sleep it drops, notification says connected. Toggle wifi off and back on works, phone sleep back off. Tried wifi never, only when plugged in. Switched to 2.4 ghz only tried 5 ghz , too. Linksys ea4500 wpa2/aes(setting) brand new. None of the numerous other devices in the house have any issues. Speeds seem awesome.
Tried factory reset nothing works. Even got sprint to get me a new phone, still no solution other than going back to el29. Currently, running fi03 stock rooted. Scared to try latest fi25. Any other suggestions would be great.

still sounds like a router compatibility issue. See if it happens on a different wifi.
The only way i can successfully stay connected is if there is no security or wep is used. Same router nothing had changed. Again worked flawlessly with EL29 update comes to FF18 and it no longer works. Sprint has said it is a known issue with ics on samsung and htc but no fix. Don't want to give up my security just to use wifi. If i roll back to gb everything works again without changing anything in the router. So i don't believe that is it. Plus, i know all about router settings not a noob. I beleive it to be something in the phone update.

My wife runs fully stock newest release and its fine. Try a different router. routers can have compatibility issues with devices. Also you say "its a known issue" but can you give a source?
I'm not saying its router settings. I'm saying it can be a compatibility issue between router and phone chipset.

I guess i should've mentioned there are 2 of the same phone in the house. Wifi works fine on the other device. Source? As in sprint tech support told me over the phone it was a known issue with samsung and htc devices, not all are affected. This is why sprint decided to replace my old non working phone for the new one.
Not sure why of it were truly a setting inside the router why would one work but not the other? Seems highly improbable to me, just saying. I do appreciate the feedback though.

So two of the same phones. One connects and one doesn't. Interesting. About the tech, seems a pretty wide declaration of an issue. samsung and htc phones. lol. There are a ton of those and its a 'known issue'. If it were a known issue, they would have it tied to a specific phone and wouldn't say 'well err um some phones work and some dont'. lol. Anyway, I don't usually trust those techs.
Back to the issue. If one works and one doesn't... Then it sounds software or still compatibility type issue.
Have you tried these things? If it were me, this what i'd try....
1) I'd reflash your phone's ROM fresh and try again. Full wipe. It's possible the update boinked your wpa_supplicant settings.
2) DHCP: stick a static IP on your android and see what happens. (dont confuse this with a static dhcp lease) DHCP does some interesting things on android phones as far as wakelocks and such.
3) In the router, turn off all the bell and whistle crap... Some of these routers have things like 'afterburner' and things like that. It can cause issues at times. Keep track of what you turn off and obviously if it don't work, turn it back on again.
EDIT:
This is interesting as well. Your not the only one.
http://forum.xda-developers.com/showthread.php?t=1847889&page=4
Try the things I posted but ultimately, you may need to just flash a different ROM version... Doesn't mean you need to go all the way back to EL26. At least you know its not only you...
So I initially called Centurylink, and they told me to change security settings. I did this, and it worked for a short period, but then dropped again. I couldn't figure out why this kept happening, and it had become quite frustrating. Then I realized that I had created a new network with a personalized name and password. My laptops connect fine to that network, but my phone won't, so I connected to the initial network created by Centurylink, and have had no issues. So I can suggest trying that as well. Hope that helps

Set up both home networks using WPA/WPA2-PSK and no issues. Did have issues at work with WEP so perhaps that's the offending solution? If so try TKIP instead.

I had the s6 edge before this for a couple days and this phone is similar from what I've noticed some apps require carrier data to provide authentication and some phones use both Wi-Fi and lte to download faster this phone does it at times it's just not really a feature to turn on and off yet like it is on the edge.

I've got the H815 and can not confirm this. I never had a phone that did this, save you activated that option within an Xposed module. I did this on my Note 10.1 2014 LTE because I wanted to check the connectivity strength of my carrier even when I had WLAN enabled. But out of the box? No.
On the G2 pre-lollipop, we could change the icon set and hide data icon when on wifi.
After lollipop, it seems to stick regardless. Annoying I know.
The only downfall of the LG is the intense amount of status bar icons. I really only used xposed to hide most of those and have centerclock. Need root first though. Not sure if xposed is supprted without a custom recovery yet. They disabled activation through the app until testing was complete.

Same to me, im on T Mobile galaxy S6, i just update mine to 5.1.1 and this anoyin bug start to show.
When im on Wifi the Data icon show up randomly:crying:
For what it's worth, I set up a tasker profile along with autoinput for when I connect to my saved wi-fi access points it would turn my mobile data off. Now it's not a smooth as tasker before lollipop, but it gets the job done.
That's a Verizon thing, same appears on my Moto X. Doesn't bother me, I'm always interested to see signal strength available even if I'm using data via WiFi.
This is how every Verizon phone has been for the past few years. This is intended and I honestly prefer it.
