Evo tethers great on 3G. On 4G only getting 3G speeds while tethering

[GoogleCodeExporter]

1) EVO
2) Froyo 2.2 (both stock rooted and Damagecontrol rom)
   Latest Wimax radio 26023
   Running earlier radio 1.36.00.04.02 because thats where I was getting best 3g speeds

3) 2.0.5.pre7

What steps will reproduce the problem?
Fire up 4G on phone.  Run speed test and get 6000kbps.
Start tether. Run speedtest on tethered device (both netbook and ipad). Get 3G 
speeds in the 600kbps range

What is the expected output? 
Sure would like to get 4G speeds.  This may be the same as 381

Please provide any additional information below.

Evo running VaelPak 2.2 with netarchy 4.1.9.1 BFS.  Apparently there's an issue 
with wireless tether running on his rom, b/c he released a mod of pre9 for it- 
that's the only thing that works.  I can't get the un-modded pre9, or pre10, 
running on VaelPak 2.2, so I can't confirm whether this fix works, but I can 
confirm that the modded pre9 is the best speed I've gotten so far (2 bars of 
WiMax in midtown Manhattan), around 1.2 mbps (vs anywhere from 5.5 to 9+ mbps 
directly on the Evo).  I'm thinking of finding a rom that will run pre10 & will 
post results when I do.  thanks for the hard work!

I'm also running Vaelpak 2.2, my kernel is kings #9 bfs, but I never downloaded 
his custom tether app. The original pre10 is what is working best for me. The 
second pre10 without the repeat binary install on open wasn't working for me. 
Or at least something wasn't, so I'm back on the original pre10 from yesterday. 
Just did a speed test and laptop pulled down 4.3mbps.

I want to clearify something here. Our software is GPLv3-licensed-software. If 
someone starts to make modifications - all changes must be published! Having 
access to sourcecode of programs is great but don't violate the GPL.

I am on Baked Snack 1.8 with Kernel 6 using the newer updated pre-10 apk 
provided here.
So far these all work for me.
1) modified pre-9 works well
2) first pre-10 works well
3) second pre-10 works well

The only big fluxuations I noticed for me at this point is the location of the 
phone, which has nothing to do with the tethering app.  I get different speeds 
at different locations in my house and my room specifically.

There's a few things I can think of...

One is somehow the Wifi radio is interfering with the wimax radio, causing 
fluxuations between one or the other.  But this probably wouldn't make sense 
considering Sprint has their official hotspot program to tether 4G via wifi.  
Which brings me to my second theory which could have fixed this issue.

Second, People should to update ALL of their radios.  The main Evo radio is at 
version 2.15.00.09.01 ~ WiMAX 26023 ~ PRI 1.77_003 

Disclaimer: Updating radios is risky and could brick your phone if something 
goes wrong, so do with caution.  Nobody here including myself is responsible if 
something does go wrong.

By modified, I mean with the changes Harald said to make in the Terminal.  
Thought I would clarify that

Just wanted to mention that Pre10 does not work for me at all using Evo

Original comment by NathanAC...@gmail.com on 10 Oct 2010 at 6:50

[GoogleCodeExporter]

I must have accidently reinstalled the original pre-10.  I redownloaded the 2nd 
pre-10 and to my findings tethering does not work.  So the original Pre-10 and 
previous work.

One more issue,  if 4G connection is lost and it switches to 3G while 
tethering,  something to do with the radio switch during tethering operation 
bugs up the application and internet connection is lost on tethered device.  
Even a phone reset I get no tethered internet connection (phone connects to 
laptop, but no internet on laptop)

Only way to fix is to clear data and reinstall app. So hopefully don't loose 
connection while using 4G folks, or if you do, turn off tethering before you 
loose connection! otherwise you'll probably have to reinstall

Any luck on this? Everyone just give up?

I'm running the original pre 10 version with much success getting acceptable

I tried that, still the same slow speeds for me :-(

wmblalock - are you using the current pre10 apk or the original? The original 
was only available for like 1 day or less.

Original comment by jack.all...@gmail.com on 19 Oct 2010 at 5:31

[GoogleCodeExporter]

I tried both with the same result. I also recently received a new EVO a few 
days ago and tried both versions on it as well with the same result. I 
downloaded the original pre10 right when it was posted, then the new one after 
that.

pre11 and pre10 still no luck, wireless tethering is often around .5mbps and 
disconnects frequently, while pdanet shows 7-8.

Pre11 works great, I am getting full 4G speeds now

Original comment by NathanAC...@gmail.com on 22 Oct 2010 at 5:03

[GoogleCodeExporter]

No luck for me with either pre10 or pre11.  Now running EvoNonsense 2.0 with 
King's #11 CFS. Pre9 still works  Strangely, the best speed I get is using the 
sprint wifi hotspot app (which works because I get my phone thru work, and 
they're still paying the $30 even though I rooted...), but it's still not full 
4g speed- around 1.5 down and 1.0 up.  

Original comment by doubleh...@gmail.com on 22 Oct 2010 at 7:34

[GoogleCodeExporter]

I have the same issue. I actually paid for Sprints wireless hotspot and got 
nearly the same results.. I now went with wifi tether pre11. As stated same 
slow results unless I connect to my home pc, then it's good. I think it has to 
do with the wireless on my iPad and the way the evo wireless signal is 
broadcast. Let's say they don't play nicely. iPad will be updating software in 
November let's see if that clears things up..

I've also been having the slow 4G issue. Just downloaded Pre11 but it doesn't 
fix the problem. Wish there would be a fix for this soon. I will definitely 
donate once 4G is working properly! 
P. S. don't know if it makes a difference, but I'm running King's BFS #4 kernel 
on stock Android 2.2

I get essentially 0 speed on only SOME pages. It's extremely odd. I can load 
said pages on the phone itself, but not on anything tethered. It affects all 
ports too, slowing things down like SSH.

Pre-11 is working for me.  Found this thread as I was having the same problems 
as everybody else running Pre-9.

Full root (not unrevoked)
Fresh 3.3.0.1
Net 4.1.9.1 Fresh Compatible

For what it's worth Pre-11 didn't work for me out of the box, it was having the 
same problem (dl limit at 1 Mbps).  I went into Titanium Backup and wiped data 
for this app which fixed the problem.

Just an update, as i'd really like this to be fixed if possible, but pre-12 is 
semi working for me now. 
With earlier versions, I'd always be getting less than 1mbps down, but now I 
get between 1.5-3mbps. 
On the phone and usbtether, I consistently get 8mbps down.

Almost there?

I have an EVO, rooted with Unrevoked, with 1.77 PRL. Using Pre14, Wifi tether 
at 4G seems to be locked at 600-700kbps, while Speedtest.net shows 4.5MBps 
while testing on the phone.
Tried to delete fixroute.sh, and successfully deleted, does not help. Running 
without any security (no WPA or WEP) and no MAC address filter does not help 
neither.
any tips or help... thanks. :)

Same issue as comment 73.  USB tethering via the "tether" app on the market 
yeilds 10mbit down 1mbit up.  4g with this app seems to be locked at .4mbit 
down .9 mbit up.  Speedtest.net on phone shows 10mbit down.

Can someone try out these 3 tests on the EVO? (if your having 4g speed issues)

Original comment by ask1ab...@yahoo.com on 3 Dec 2010 at 4:19

Are there any updates to this?  Recent updates to wifi tether over the past 
couple months have increase 4G tethering speed from really really slow, to just 
slow.  I tried deleting fixroute.sh too, but it didn't fix the slow 4G tether 
problem.  I still get ping times 3 times slower on a tethered laptop compared 
to the phone, and tethering speeds are limited to around 1mbps, compared to 
around 4-5mbps on the phone.

Due to the increase ping times, it actually works better for me just to keep 4G 
turned off.  While the 4G is roughly the same speed in terms of bandwidth, if 
not a little bit faster, the ping times are a lot slower when doing 4G 
tethering compared to 3G.

Hey everyone, I have been looking high and low on the internet for a wifi 
tether and 4G fix.  Like everyone on this forum when I perform a speedtest I 
get between 4 and 10mb on my phone and between 0.5 and 1mb while on wifi 
tether.  I tried deleting the fixroute.sh file using adb shell and was 
unsuccessful at obtaining better speeds.  

I recently purchased and downloaded root explorer for an unrelated reason.  
While exploring the phone's internal folders I saw the fixroute.sh file and 
decided to delete it.  I followed up by clearing wifi tether's data and 
reopening the app.  I couldn't believe it but I am now getting over 5mb while 
on wifi tether.

Hope this also works for you guys.

ok~I found the speed of 4G tether to my laptop is very good ~ >500KB/s

but 

on ipad ~ the speed is bad!!  50KB/s

I dont know why!!! so for those you say the 4G speed is slow, try laptop.

I'm running Myn's Warm RLS5 ROM and did the fixroute.sh fix and still am having 
some problems. It's faster then it was before I removed it but still aren't 
nearly as fast as on the phone. Hoping to see this get fixed soon.

Just tried the latest wifi tether and I think the 4g issue has been fixed.  I'm 
also running myn rls5 and I'm getting 8 mb with the new wifi tether.

I'm still having this issue, and I've tried basically every fix on here 
(deleting fixroute.sh, changing channels-though I haven't tried all of them, 
trying different versions (2.05 pre 7 - 2.08 pre 1). Think someone could maybe 
troubleshoot me from step 0? (maybe starting with restore factory firmware or 
doing a hard wipe, etc?).

I'm currently using the Synergy Rom (which is also the best Rom I've ever used) 
which is based on sprint's latest Android 2.3.3 rollout to fix netflix.

Also, I ran across this little gem that apparently hasn't been worked on in a 
while:

http://code.google.com/p/android-wired-tether/

I installed it, ran the program and started tether (without a hitch, mind you, 
pretty f'n sweet program and nice for saving battery on phone when only needing 
access to 1 comp), and sure enough, I'm getting 4g speeds (appx 5.5mbs down and 
1.2 up). 

Not sure if this is helpful, but at very least it's a workaround to tether at 
4g, albeit with a USB cable.

Consider releasing a test apk to collect activity on other channels.  

Heavily used spectrum == less throughput for y' all

Instead of "speed" test sites download an iso of redhat to allow for TCP magic 
to adjust in first four minutes

If we can use the same method Wired tether is using then should be golden or if 
we can use the same method as other apps on the phone. Although I believe the 
problem has to do with the evo wifi adapter. I noticed I get full speeds only 
when im close Which is a problem for me because the best signal is 3 floors 
above me. I get like 15mpbs which makes my dl/ul significantly lower even 
though that should be enough. So i believe its related to the throughput.
