[Q] Help with 4g connection (HTC Evo 4g)

I moved to a new apt about a month ago and have a great 4g signal (sprint is my carrier). For the first three weeks the 4g worked great. Now I will be connected to the 4g signal and streaming a video, playing a game, or doing school work and the connection will just cut out. I will still be connected to the 4g signal and have full bars but have no data connection. I connect to the internet with pdanet or wireless tether (I have tried to use my phone's browser as well when this happens and it also does not have data so I know this is not a pdanet or wireless tether issue). I can turn off the 4g and reconnect with 3g service. I will then turn on 4g again and it will take a good 5 to 10 min before it will reconnect and the process starts over again. I generally can get between 5 and 30 min of connection with 4g before it flakes out.
I could not find this issue on these forums anywhere and have enjoyed reading threads on here, but cannot find this issue posted anywhere so far.
What I have done so far:
1.Restore
2.Reset (installed Azrael's rom with Netarchy's kernel in place of stock sense with unrevoked I had before)
3.Updated prl
4.Updated profile
5.Changed the Wimax sleep mode setting from 10 seconds to 300 seconds. I have not had a chance to test this but do not see this helping considering when it cuts out I am generally in the middle of something so there would be no chance for the connection to time out.
6.Contacted Sprint multiple times and been transfered around and got a confirmation number on a ticket for them to check the 4g signal (still a possibility it is on their end, just want to make sure its nothing on my end)
Are there any other settings or things I can try on my end to verify that it is either on my end or sprints end? I really would like to get this working, it is my primary source of internet and I need it for online classes. I have rooted my phone and do have my msl number so if there are any tweaks I can do with these please let me know.
On a final note thank you to everyone who contributes to these forums. This is one of my first posts here but I have been a regular reader since I got my Evo. I am a huge fan of all the work that the devs and posters put into this site. This is a great resource and I am very grateful for any responses that anyone can provide for me.
P.S. I hope this is the right forum for this topic, if it is not please let me know and I will move it asap!

I apologize for posting in the wrong forum. I have moved to the Evo page. Any dev please delete this post. The new post is at
http://forum.xda-developers.com/showthread.php?p=11108597#post11108597
Again sorry about this, I am brand new to the site.

From the posts that have read 4g problems almost always are Kernel related... Especially Bfs kernels.
Have you tried any other kernel and duplicated the failure?
Net's 4.3.2 cfs kernels work great with my 004 hardware EVO running MikFroYo 4.4 (IMO the absolute best Rom choice for your EVO)

[Q] Tethering issues Xoom to HTC Thunderbolt

Need some help.* I have a 4G Xoom with a 1GB data plan, so when I am away from the house, I tether it to myHTC Thundernbolt, which I have an unlimited tethering plan for.*
The problem I am having is this.* The devices stay connected just fine, but data thruput is spotty.* Little things, like emails, GTalk, etc gothrough just fine.* However things like web surfing hang.* I will gettwoor three pagesok, but then I go to a page and it hangs while loading the page between 1/3 and 1/2the way through the page.
Here is the info.*
Xoom is rooted, but stock.* Issue is pre and post root, pre and post 4G upgrade, and a couple of factory resets.* Pre and post update to 3.2.2 build HLK75. Connects fine on my network at home, and others like at resturaunts.* I've forgotten the network, etc... I have tried multiple browsers too. Happens with stock browser, Dolphin HD, Dolphin for Pad, and Opera. (I hate Opera) No other data issues on the Xoom. WiFi at home is smooth as butter, so is the 4G when I do turn it on.
The Thunderbolt.* Stock and unrooted.* Happens pre and post update to 2.3.4.* I have done factory reset, set the hotspot back to standar, changed channels, security, etc....* Also, the hotspot is set to always be on, not to time out. No data issues on the phone.
It is annoying to constantly not be able to use the net when aeay from the house. Help, please. Just let me know if you need more info. One last thing. It doesn't matter where I try it at. Hotspot at home (testing it) at work, or out other places. Also, I have tethered my laptop to the phone with no problems multiple times.
Thanks....

Sorry for the formatting and astriks, don't know how that happened.

what app are you using to tether have you tried any others like easy tether?

I am using the stock mobile hotspot app on the Thunderbolt. I have the unlimited tethering feature. Haven't tried another app, since I am paying to have the ability

After several days of testing, etc.... I think I have figured it out. Happens when the screen on the Thunderbolt times out. At that point, the hot spot stops responding. I checked and have it set for Always On, and tested the other two time frames there. Nothing changed. Guess I should call tech and try a CLNR.

I use Barnacle with my TB to tether both my Xoom and Nook Color with no problems. Have used Wireless Tether but prefer Barnacle for no particular reason.

Your the second to say something about a different app. I looked on the market, and all require root access. Haven't rooted yet.
Interesting development, after doing everything I could think of, I turned off the security as a last ditch effort. Goes against everything security wise, but..... It seems to make the difference.still a little latency, but it works.

You don't have to root your Xoom, you run the wifi tethering program on your Thunderbolt which does have to be rooted.

Sorry, I meant the Thunderbolt being rooted. The Xoom is, my Thunderbolt isn't. If I can't get this resolved any other way, I will root it. Going to call tomorrow and see if I can get it replaced and try a different unit first.

Now realize that I really should have posted this up in the HTC Thunderbolt area. It's not a Xoom issue, but a Thunderbolt issue.
MOD's, if I can request, can this thread be moved like that? Thanks...

USB tether 4g never works correctly? AOSP

I've tried every AOSP Rom/Kernel variations and I can't get anything to stay USB 4g tethered for more then 5 minutes. Tshed was flying with stock CM7 USB tether and then all of the sudden doesn't work. I tried all AOSP Roms. And wired-tether 1.4 is what I use. Please help me out. I have this phone for another year and that's all I'm missing. Please help. A trick, known set up, etc maybe. Anything not to have to reset the app every 3-5 minutes or so. I can't believe I haven't seen this brought up lately? Is it only me?

Have u tried pda net?
Sent from my SCH-I405 using XDA App

Yeah u have to install software on every PC u wanna use and that kinda sucks but I still get the frequent resets and they're connection is pretty slow. I have to reset pdanet, wired-tether 1.4, etc. Every few minutes. I used watershed 1.2 cm7 stock USB tether and it worked beautifully for about a day and then nothing. So I flashed imo's kernel and stock tether doesn't work at all but I have to reset wired-tether 1.4 every 3-5 minutes or so.

I don't use USB tethering often, but when I do, the built in version always works perfectly. Tried it on OMFGB, liquid AOSP, and workshed CM7. An older version of Imo's kernel (version 4 I think) supports USB tethering.

I use easy tether and have no issues. For wifi tether I use opengarden (faster than USB tether) don't have issues with either.

And its only when I try to use 4G. 3G will stay tethered all day long if i let it but its just way to slow. I usually get 15-20 Mbps down with USB tether 4g. Thats fast as hell. I wish I had a little Porto WiFi adapter for my work PC's. Cuz yeah when I wifi tether my AOKP TouchPad I dont have this problem.

There may be something wrong specifically with his ROM. I have USB Tethering working fine on my Sense-based ROM, but I tried his and it would work for 15 seconds and stop working, then never reconnect. I tried having something persistently connected to internet on my phone but that didn't help either.

I use the ClockworkMod Tether. Works on every ROM I've tried.

I was hoping I wasn't gonna have to resort to sense but I might have
to. I need this to just work. No installer PC ware

Ive tried my Phenom2 x6 and 2 Diff. Core 2 Duo's (that's just my House).
A few Newer laptops. Wifi tether worked no problem, just alot slower then straight USB (when it works).
There were a few at work I tried and No good either.
Back when I first started bringing up this issue (Sept.) I was told It was a known 4g issue (By a great Dev who has since moved to the Razor, hint hint) and that's why there is no problem with 3 g tethering at all. Just wondering If someone had a set up that completely works with out having to reset every 5 Min or so. I think I had good Luck with ThunderShed 1.3 this weekend. I fell asleep FTPing some stuff from my friend (good size) and It was finished when I woke up. That's a good sign so far. I just need one person to see this thread that has the perfect setup for 4G USB Tethering, 24/7 if need be. It would be great to know.

I always just used the built in wired tether with cm7. I had an issue once where it would drop in and out, but after doing a total reset and reloading cm7 once again, it was fine. I also don't use the DNS with the phone. I switch my DNS on my PC to be layer3 DNS (4.2.2.1 to 4.2.2.6). DNS is allegedly one of the ways they can track what device the transfer is coming from.

This could be big help. Im at work now but when I get home I will check into this more. Thanks so much. I can never get the built in USB tether to work from CM7. TShed's built in CM7 worked for a while then just cut out. The little name your connection from Win7 popped up but had no Internet at all. May be something to this. Thank you.

Might also try disabling IPv6 and anything else not needed on the connection as it won't actually tether through it anyways. It could be causing a conflict somehow

So you are running which cm7. I am now running TShed 1.3 and stock tether was great for about 20 minutes. Then just stopped. So turned off tether reset mobile data and 3g 4g. Nothing. Not even wired 1.4 works. Rebooted a few times, I've been at this for bout an hour now and still nothing. Not even wired 1.4. So I switched from auto to 4.2.2.1-4.2.2.6 DNS. Thanks for that bit of info. Now do I have to do that every time? Anyway I'm frigging stuck here and I hear all these people's are working fine.

If you set the DNS on your PC, it should stay that way. You can always verify if you need to. But yeah, I used cm7 and the built in tether just fine.

So every time my USB connection starts it gives me a new Connection(I'm up to like number 54. So I have to go in and set the DNS and disable ipv6 every time? How do I get my USB tether settings to stick on my Win7 Ultimate x64 every time I start my tether instead of it thinking its a brand new connection every time? I got ThunderShed 1.3(stock kernel) installed now and the stock tether isn't working but the wired-tether 1.4 is working great after a couple resets. It must have stuck for a few hours until I shut it off. That's great considering how bad of a time Ive been having.

Not sure why it keeps changing your connection number. It's never done that to me unless I've flashed a new ROM or something when I've used it on windows 7. Turning off and turning back on your wifi device might also do it (the one attached to your PC).

Mobile Hotspot function properly on stock S3?

My thunderbolt is dying and I need a new phone. The S3 for Verizon looks to be the winner. Just need to know if the stock hotspot works well because on the thunderbolt it would always disconnect after 5-10 mins of usage. I need a reliable connection for wifi on the road. I'm going to leave the phone unrooted and stock for a while until I know it's all good so that is why I am asking about the mobile hotspot functionality.
Thanks.

I'm stock rooted and use the hotspots app nightly for me and 5 others at work to tether too. Occasionally the apps stops communicating, I need to just toggle the app, turn it off then on again. Then it works fine again, only happens once every few days of tethering. We all tether fine. Some as far as 60+ feet away, work in cubical enviornment, no walls. Yeah they don't get full bars. But I've heard no real complaints from anyone.

tethering on fp5?

Has anyone gotten wifi tether to work on fp5? On 3.1 pre 12 (the one that worked perfectly before) my computer can see the network but it says limited access when I try to use it. On the latest one in the play store my computer can't even see the network and on the phone it says "tethering started with issues" in a toast notification.

So far I haven't had any problems with FoxFi. Computer picks it up and connects automatically.
Tweaked out on Circuitry

Had a hot boot when I turned it off but it worked fine
Sent from my SCH-I510 using xda premium

So far I found that tethering is nearly worthless on FP5. FoxFi won't allow me to connect the computer. Wifi tether will hot reboot when stopping sometimes. It will also actually spit errors and basically bork the wifi driver when restarting-- reboot required to fix it. Additionally, when it does "work", data stops periodically (likely sleep state issue-- which is probably a kernel issue) and only resumes when the turn the screen on. I thought about trying to find an app that prevents the phone from sleeping. This happens on the beta2-2 as well as pre12.
My nerd-rage got the best of me and I loaded up Froyo. No problems there. I have a CWM of Gummycharged Froyo and Tweaked3.0 and Tweaked 2.0, so far no issues restoring.
Tweaked 2.0 gave me the same issues as Tweaked 3.0.
I am using FP5 radios on Froyo with no tether issues.
This is absolutely not knocking on how great Tweaked is, it's just that something is preventing proper wifi tether.

Do you have disable wakelock unchecked?
Sent from my SCH-I510 using xda premium

I installed and tried out FoxFi. It works and it shuts down ok. The weird thing is I now have the native mobile hotspot icon in my status bar and in the notification pulldown. If I tap it in pulldown it takes me to Mobile Hotspot settings and there it shows itself to be shut off. Is there a process still turned on that I don't know about? I turned off FoxFi in Task Manager and tried to find Mobile Hotspot in Running Processes and Titanium. I found nothing by that name. Maybe there's another name for it.
I'm about to try rebooting the phone but I was hoping to find a way to shut this off without it.
Update: Rebooting does shut it off. Is there something I could freeze in Titanium to keep this from happening again?
Update 2: Looking through Titanium there are 2 Wi-Fi Access Points. One is labeled 101 and the other is XML. Might one or both of these be the culprit? Can I freeze one or both of them?
Ok Titanium won't freeze either of them.
Update 3: I think I know what I did wrong. I think I switched the computer to another connection without turning off FoxFi first. So it appears to work good for me. I don't think FP5 causes the issue we're talking about here.

I've used PDANet for a wired connection too. It works great. The problem there is they won't let you use it for secure sights without paying for it. They want $15.95. I'm not willing to pay that much for it.

It sounds to me like you are trying to mix and match kernels and roms. If you want your phone to work right you need to be on FP5 straight across the board. FP5 stock absolutely smokes everything that came before. Even FP1 PB&J on Ext4 is a dog compared to it. Then you run Tweaked 3.0 on top of that and you have a smooth, problem free phone. At least I do.

Disable wakelock seems to keep the display on, and I don't want to burn out the screen. That does keep the connection mostly stable, but I still have issues with hot reboots and not being able to start and stop the and restart the service properly.
In Froyo (and EP4D, I believe) wakelock can be disabled and tether works flawlessly.
Another issue I noticed is that on FP1 and FP5, uploads on the phone work fine, but uploads over tether will pretty much kill the connection until enough time is given without uploading data.
@stueycaster
I noticed that mobile hotspot icon as well with FoxFi, but I never could get data through, even though I was connected to WiFi. I haven't had issues with PDANet, but yeah it costs money, and it is lame to be wired.

My issue with the Mobile Hotspot icon was that it stayed on after I'd shut off FoxFi. It didn't stay on as long as I shut down Foxfi before I switched my computer to another connection. The first time I switched it then shut down FoxFi after and the icon got stuck on. It went away with a reboot. FoxFi worked great for me. I even got 13MBps download speeds through it according to Speakeasy.
Actually I don't think of a wired connection as lame at all. If there's a choice between wired and wireless I'll choose a wire every time. It's secure. I almost lost my bank numbers to a thieving internet asshole once and now I'm very careful.

I've tried the most recent two PBJ kernel with Tweaked 2.0 and the stock FP5 kernel with Tweaked 3.0. Same thing. As I recall, Imoseyon 4.0 kernel works on EP4D with tether just fine. I've had better luck with Froyo though, but that is anecdotal evidence. I've noticed improvements with each newer baseband version no matter what ROM/kernel I'm on. I am nearly certain that baseband is free of dependencies of ROM/kernel.

Wireless is the way to go for me, then I can place the phone for optimal reception. With access control and WPA2 of Wifi tether, I don't see how anyone would be able to join your network. If you connect to some random wifi network, then you'll want to be cautious that someone isn't arp spoofing or packet sniffing.
I haven't seen an app that beats wifi tether, the customization is much better than anything else I've tried. I know there is a problem with FP5 base or the FP5 kernel with wifi tether. I just don't have the knowledge to troubleshoot it.

Thanks for the heads up on this. Runs perfect on my stock ROM.
