Data cuts out constantly when using wifi-tether...

[GoogleCodeExporter]

Which device (manufacturer, type)? Droid Incredible

Which firmware is installed? Unrevoked rooted the latest OTA 2.2 pushed out a 
few weeks ago...

What version of wireless tether are you using? 2.0.5 RC2

What steps will reproduce the problem?
1. Simple: Use Wifi-tether with factory default settings.  
2.
3.

What is the expected output? What do you see instead?

I expect that my laptop should continue to use data un-interrupted on the 
phone.  However, after a short time (usually within the first 3 - 5 minutes of 
use (or 5mb of data use) I lose my internet connection on my tethered laptop.  
Especially when downloading large files.  Then, on my phone, I will notice that 
the "3G" symbol will disappear for a few seconds... only to reappear.  This 
obviously means I am losing my data connection.  I have tried any combination 
of channels, to using security, not using security... nothing matters.  The 
only way that I can positively impact the problem is if I power off the phone 
and reboot it.  If I immeadiately start using wifi-tether, I see much better 
results.  Sometimes it will allow me to use it for almost 20 minutes and use 
much more data (have occasionally cracked 100mb)... however, inevitably, it 
will fail again. At the worst possible time. 

Please provide any additional information below.

A few other things iv'e noticed in testing:

-If i'm just simply web browsing, its not as big a deal:  Iv'e gotten so good 
at predicting when its going to fail that I can wait for the data on the phone 
to stop and once it comes back I just need to refresh the web page on the 
browser and usually, it will keep on going (for a few more minutes).  This 
doesn't help me when downloading large files or connecting to software that 
requires a constant data connection.

- Environment doesn't matter: Iv'e tried using it at home... at work... on the 
road.  It doesn't make a bit of difference.

- Apps running on the phone and / or Apps using data:  Iv'e tried many 
combinations of disabling all widgets, shutting off sync on as many things as I 
can... none of which makes a difference.  I thought at first something on my 
phone was interfering.  This does not seem to be the case.

-I don't believe its my data connection on the phone:  I've never noticed in A 
LOT of use, that the data stops working in any other scenario than when I am 
using wifi-tether.  It seems to only happen with this application.

-This is the second phone iv'e had the problem with:  My original DInc died a 
month ago... it also had this exact same problem.

If there is anything else I can do to help, please let me know.  I'm excited to 
have this as a working feature on my phone!

Thanks!

Could you please provide "adb logcat" and dmesg output?

Here is a howto for "adb logcat":

https://sites.google.com/site/androidhowto/how-to-1/save-logcat-to-a-text-file 

Howto for dmesg (commands using adb):

adb shell
su
dmesg > /sdcard/dmesg.txt

This will generate a file named "dmesg.txt" on your sd-card.

Please upload both files here.

Thanks.

It appears as though latest version 2.0.5 (from today)is much better... I did 
not reboot my phone after installing and i'm at 161MB downloaded over the last 
hour or so without a single failure.  Not sure I ever gotten this much use 
before a failure.  I will keep you posted...  Let me know if you'd like me to 
try anything else!  Thanks for the quick response!

Well, that was short lived... I used it yesterday quite a bit with no issue.  
Today it is back to disconnecting.  Would you like another log file?

Even with the new experimental versions it has not improved. Any idea if this 
is something that can be fixed?

See my comment #1 ... I need the logs.

I emailed the log to (android-wifi-tether@googlecode.com)... Does it literally 
need to be "pasted" in this forum when you say "Please upload both files here?" 
 Don't these logs contain (somewhat) personal information?  That's why I did 
not...  Please advise.

Also, (as I included in the email), I get "permission denied" errors when 
trying to run either of those commands you reference above.  What I gave to you 
was Xtralogic's log collector which contains (2) failures.  Will this be 
adequate?

Thanks!

Here is the log requested... I just captured a new one that doesn't contain any 
personal information.  Let me know if you need anything else.

Thanks!

I see a lot of mentions of "wrong apn" in your log.  Up until now, I had never 
known what APN was, upon lookup, I discovered that it is "Access Point Name".  
You should be able to change APNs in the wireless settings -> mobile networks, 
but some ROMs prevent it.  Using APN Manager (found in Market), I discovered 
that my APN was simply "internet".  Further research revealed that the Verizon 
APN is supposed to be ##########.vz3g.com where the #'s are your 10 digit phone 
number.  I have switched to this APN and will let you know if I get any better 
stability, I also have those "wrong apn" errors in my log.

Excellent!  Thanks for the heads up on that... I will check that out as well.

I'm not certain the information I found was correct as vz3g.com goes absolutely 
nowhere, so I'm not entirely comfortable using that.

harald.mue, I found this information regarding APN: 
http://community.vzw.com/t5/BlackBerry-Devices/What-are-the-APN-values-for-Black
berry-9630-Tour/m-p/318504
Apparently this guy with his Blackberry app told it to use TCP/IP as opposed to 
APN, perhaps that could fix our Verizon issue?  I've seen people with Droid X, 
Droid 2, and Incredible all with this same issue of 3G dropping out on Wifi 
tether.  What's funny is that it happens with the 3G Mobile Hotspot app as well.

harrymonahan3:  Changing the APN to #.vz3g.com didn't fix it.  It seemed to 
work, got almost 50MB through and it started crapping out again.  I just 
started looking some more and found a mentioning of #.vzw3g.com and that domain 
is actually owned by Verizon.  I think the other info may have been a typo.

Sorry for posting so many times, using vzw3g doesn't work either, I've also 
found mentionings of using "emgsm.vzw3g.com" and that didn't work at all 
either. There must be something else going on aside from this "wrong APN" error.

(Sorry about extra post/delete, posted from wrong Google account)

I did not realize that this also happens with the 3G Mobile hotspot app as 
well!  I'm glad I didn't bite the bullet and pay for it.  Do you know if it 
happens to un-rooted phones that use the built in 3G Mobile hotspot as well?  
I'm starting to wonder if somehow (as you mentioned above) that some ROM's 
don't allow APN changing.  I wonder if this is a "rooted" phone issue.

As far as I know, the same thing happens with unrooted phones using PDAnet and 
3G Mobile Hotspot.  There are quite a few mentions on the Verizon and Motorola 
forums.
