ridiculously slow 4G WIFI tethering!

When I measured speed from speedest.net app on my evo with 4g on, I get between 3-4 mbps download speed - and web sites and such load very fast. But when I tether my evo with 4g on and measure the speed on my laptop, I get barely 0.2-0.3 mbps download - and watching streaming content of the laptop is useless - all it does is buffer forever.
Anyone know how to make this work?
Thanks!

No one has a clue?

What tether?
Via EVO on XDA app...

I am speaking about the wireless tether app

The latest version?...ie, one off market?
Via EVO on XDA app...

I am using "2.0.5 pre 8" which came with Fresh 3.2.0.0

I'm using 2.0.5 Pre 9 and with 4G am not really doing any better than you...then again, on the phone it's slow as crap, too.
I don't think it's your wifi tether...i think it's the app giving you false readings. I used to use usb tether (before EViO went to a kernel that wouldn't support it) and the speeds weren't any better.
You can see if it works on your kernel and verify wired vs. wireless speeds...

Bumping because of the same issue
I get 8 to 10 mbit consistantly on my 4G on my speedtest app and transfer speeds when downloading files on to my phone.
However, with Wifi tether I can't get any higher then roughly 1.5 mbps on my laptop. I've tried different channels, different security settings, no security at all... etc.
I do suspect it's a software limitation because the app itself is meant to tether 1x/3g speeds, and 3G itself i'd say averages between 500kbit to 1.5mbit download speeds(I'm talking roughly... could be faster or slower).
So my guess is the developers haven't bothered with the coding to make it work well with faster connections. There's no reason it should be a hardware limitation because our wireless chips are G and N compatible. I've gotten speeds around 17mbps up and down on wifi on my evo.

I think you may be right, as I'm starting to hear from quite a few people that are thinking the same thing. Everyone has crazy speeds with the SpeedTest App, then are lucky to hit 1meg with the computer.
Can someone with the "correct" kernel test the wired tether speeds???
EDIT: Just tried Calk's EViO Beta which worked with wired tether and the speed is just as slow.
The question now is, does the Sprint HotSpot tether at 4G speeds? As I said before, Calk released a framework flash that allows the use of the HotSpot without it on your plan, but it won't work (for anyone) on 4G, and automatically kicks down to 3G...

Fixed the 4G issue!
This was posted by creator of wifi-tether as a possible fix, I tried it and it fixed our issue. I now get full 8mbps download via wifi tether.
To make sure things go smooth, I would make sure wifi tether is NOT running in the background
Go into terminal on phone or adb via computer:
adb shell
su
rm /data/data/android.tether/bin/fixroute.sh
Not sure why this fixes it, but not complaining

Thanks for sharing!

Deleting fixroute.sh mad wireless tether lose my internet connection after about 30 seconds. Did he have an updated script?

I had a similar problem. Fixed it by setting my setcpu profile to performance for the time I was tethering.

Didn't work for me either...

FWIW, WiFi Tether on my Hero would download at 100-120KB/s all day long...on 3G...Possible EVO issue???

Worked for me!

I downgraded back to 2.0.5 Pre 7 and getting good speeds now! Also added benefit is cpu running cooler.

Can you upload the .apk?

glad to hear the developer is working on the issue.
anyone hear of a work around for devices that can not connect to an "ad-hoc" wifi hotspot?
PS3 will not see an "ad-hoc" wifi!

[Q] CM9 Alpha 5.0 - Wireless Hotspot Woes

Materials:
I have Shadow Kernel v0.5 patched to my clean install of CM9 (wiped data/cache/dalvik); overclocked to 1200Mhz using the built-in CM9 performance settings with InteractiveX governor.
Issue:
Every time I try to enable the built-in CM9 wifi hotspot, it seems to just automatically deactivate.
Procedure:
While having wifi on and successfully connected to the internet via my home router/work router, I tap the check-mark to activate the hot-spot, it displays that it is attempting to activate wifi (even though it is already on) and then displays the small icon indicating that wifi hotspot is active; after a few hundred milliseconds it proceeds to display that it is deactivating wifi and we are back at square one (but now the wifi is off).
Results:
This issue is repeatable. I can duplicate this problem consistently even after doing reboots. I have also tried to activate the hotspot with the wifi preemptively off or combined with 4G on/off and it seems to hang and occasionally crash to an automatic reboot when attempting to activate wifi when hotspot is toggled on.
Question:
Is anyone else having similar issues? Or is it simply my phone acting retarded?
Edit:
- I have tried down-clocking the CPU from 1200Mhz to 1100Mhz and it seems to be spotty with reliability regarding staying an active hot-spot.
- I have tried down-clocking the CPU from 1100Mhz to stock 1000Mhz and the hotspot is still unreliable.
- I have kept the clock-rate at stock 1000Mhz and switched the governor from InteractiveX to stock Conservative, the hotspot stays on, but it fails to assign IP addresses to anything. :'(

1. Don't flash a custom kernel. To me, OC is a joke. It may speed up the device, but it just drains battery and the phone is already fast enough. They bring up issues that can easily be avoided.
2. Wifi will never work as a hotspot. 4G will work eventually, however the whole idea of tethering is using your signal to create what is basically just wifi for other people, or your computer. Why would you or anyone else need a hotspot if wifi is already available? That's just redundant.
3. If you use 4G frequently, there is an app on the Android Market (or should I say Play Store? lol) that will allow you to create a wireless hotspot based on your 4G connection, however it is not yet built in to the system.
Hope this helps.

Hello Acer, thanks for the reply!

Noted. I will stay at stock clock-rate then, but that custom kernel offers some improvements that I feel are important.

I believe I have caused a misunderstanding, I wish to utilize my phone as a wifi hotspot to access my phones 3G/4G Wimax. I have done this successfully with stock Samsung roms. My goal is to cancel my Comcast cable internet because they are raping me without a condom right now.

CM9 allows you to do this without an app.

You were very helpful! :-D

I too had trouble initializing the hotspot built in to CM9. It would activate then deactivate. I left it on, rebooted, then went to try again, it activated, deactivated then reactivated and stayed on. Then it worked fine after that.

You are supposed to be connected to data, not wifi, since that's what you're trying to tether other devices to. When you press the Portable Wifi hotspot button, it says "turning on wifi...", think of that as saying "turning on wifi hotspot", not wifi as in your router.
Turn OFF wifi, turn ON 4g/3g, make sure it's connected to data, then turn on portable hotspot. However, you did mention that you've tried several combinations. I have the same setup as you and this never fails for me. I think I got a reboot once awhile ago but that's it.
the OC is not the problem, I'm also at 1200mhz on shadow.

I am having this exact same problem after flashing cm9 beta 0

[Q] slow wifi tether speeds - mikg 3.11

Hi, hoping someone here can help with this issue…
I have read through the Q&A and tried the fixes mentioned with only one working – the proxy server setting posted here: http://forum.xda-developers.com/showthread.php?t=966418
My problem is that prior to this rom, no fix was necessary – wifi tether on 4g was as fast as the speeds I was getting on the phone itself. Now I am lucky if I break 200 kBs /sec tethered (w/o the fix). And this fix only works for surfing and downloads via the browser. I still get the same crappy speeds if I am dl a torrent.
I am running MikG 3.11 – no mods, themes, or kernels. Just the plain rom. Using Amron recovery and wiped everything before install. No partition. I used to run Konis III, then the Konis IV and both worked fine with wifi tether (2.0.7) “out of the box”.
I’ve tried several different versions of wifi tether, ran the command to remove the routefix.sh , cleared the dalvik-cache, all with no luck. Have updated radio, prl, wimax, etc, and updated my profile. I read somewhere about unlocking wireless n, so I am about to give it a try, but hoping maybe someone here has an idea. I see most of the posts are older, so maybe there is something easy I am missing.
Tia for any help.

I never really had any luck with the tethering apps or unlocked sprint hotspot. They were all fairly slow for me. The only rom that had great tethering (built in) was CM7. For some reason, Sense roms never tethered well for me.

Yeah it turns the 4g radio off when you turn on the the Sprint hotspot use this

I use the Jan build so I haven't tried the new but they all have worked flawlessly on 4g

I don't use the hotspot, only wifi tether for 4g. i've tried many versions with no luck.
trukenx, are you on a sense rom? do you get full 4g speeds? i'm just a bit frustrated because it used to work on Konis (sense rom), and then not for mikg 3.11. I falshed back to konis and now that won't work properly either (meaning i won't get full 4g speeds while tethered - i can tether, just at way reduced speeds ).
i'll keep trying other builds of wifi tether. Evocm7, do you get full 4g speeds when tethered on cm7?
thanks again

I was never able to test tethering with 4g since Sprint scrapped WiMAX before they brought it to my area. However, 3g tethering was much faster with cm7's built in tethering than an app or unlocked hotspot on a sense Rom so I would assume the same would go for 4g. I do not have my EVO or Sprint anymore to test in an area with WiMAX. Just couldn't stand sprints internet anymore. Miss my EVO though

ad blocker maybe? i know it slows down 4g on the phone itself

great point with the adblocker, it could be limiting the data pass through on the tethering also i would wipe the data on the currect hotspot or back up and completely uninstall it also check the settings on other tethering app open garden was out and pretty much mirrored the free WiFi tether code... and lastly check the setting and firewall of the device you are using make sure that is also not blocking or limiting the network speeds of you tethering connections.. eg port blocking, bandwidth throttling, etc.

Thanks, but no luck. Odd that it used to work fine, then all of sudden not anymore. Well, using the proxy settings I can get good speeds via the browser. Any settings for utorrent to get the same speeds? I tried using the same settings posted for the proxy fix, but no dice...
thanks again.

[Q] Speed Problems with Wifi Tether

So I went ahead and used the Root with Restore by Binary to get superuser as soon as I got the phone home. Upon installing wifi tether I've found a little bit of an issue and I can't quite figure it out. When I set it up as an ad-hoc network I get my fast 4G speeds (4-8 megabits) but when I try to make it a wifi hotspot so the Playstation can see it, the speeds start crawling at .4 megabit. I figure it has to be something with the radios or something but I'm not quite sure because I don't have a lot of knowledge on that part of the phones. I guess I was just wondering if anyone else had any issues with this and if you solved it, I could use a helping hand. I have used the Auto, generic, generic JB/ICS wan0 and wan1 profiles. Thanks in advance for any input.

my setting's
my setting's are device profile generic ics/jb wlan0 with mms clamping check and routing fix check..had not problem on speed while playing online

yeah i switched it back and it still slows dramatically. which version are you using?

[Q] Most efficient WiFi Access Point option

Seeking advice for the most efficient WiFi Access Point configuration on the vzw m7 - native CM11 WiFi AP vs. the Mobile Hotspot in NuSenseSIX; optimal CPU governor and other kernel options, etc.
I'm doing an experiment to see if it's feasible to use my vzw unlimited data plan and HTC m7 for all of my phone and Internet usage (personal and business usage). I work primarily out of a home office, and my LTE service at home is very good. It actually has more bandwidth than my landline ADSL+ service but with higher latency.
The problems thus far:
battery usage - it drains really fast and charges very slowly when using the mobile AP (kernel optimizations, etc?)
latency issues tend to annoy VOIP applications (can this be tuned or is it just what is?)
AP setup and teardown - since the AP needs to be active when in the vicinity of my home office, but ruins battery life when I'm out and about, I'll probably look to use tasker or something to fire up the AP when needed - suggestions welcome on the best approach
I'm not convinced I can cut the proverbial cord yet, but it's feeling like it may become possible soon.
