[Q] Xoom Not Using Full Bandwidth of Tether - Xoom Q&A, Help & Troubleshooting

I have a Droid Bionic (unleashed 1.4 rom) and Xoom (tiamat 2.2.1 manta ray rom) and am having some issues getting multiple tablet devices to use the full potential of the tether bandwidth of my Bionic and a Thunderbolt. Also tested a nook with cyanogen on it, which got even more horrid speed test results then my Xoom.
I do currently pay for the tether on Verizon for my Bionic, my buddy does not, he uses a custom rom and root.
When testing this I have a really good 4G signal, and also have a buddy with a Thunderbolt which also has a very good 4G signal.
When running a speed test on speakeasy on either of our phones we both get a consistent 25 mbps down. If I tether my Xoom to his device or mine, I get about 6 mbps on my Xoom, but still get 25 mbps on the Bionic while it is in tethering mode.
I have tried turning off encryption, different channels, and tried different wireless tethering apps. Is this a limitation of the technology itself, or possibly a software issue? I am wondering if the tether automatically throttles the bandwidth, this is kind of silly if only one device is currently connected to it.

I am just guessing here, but I see two possibilities.
-Yep you are correct and the tethering speed is throttled
-You are running into a hardware limitation of how quickly the phone can pass the data through from the 4G WAN to the WiFi LAN.
Have you tried tethering to a laptop to see what kind of speed you get there? I would guess that it will be limited as well, but still an interesting data point.
Then try to get multiple devices connected to the tether at the same time and do a simultaneous test to see what you get. My guess is that the WiFi chipset in the phone may have some limitations.

Wifi Tethering and Mobile Hotspot Confusion

Heres what I understand:
$30 Unlimited Data plan to the phone (as usual)
Optional $20 Wifi Tethering with 2GB cap (through Verizon App?)
When 2.2 comes out, will the built in Android Wifi hotspot be removed? Or will it work without the $20 wifi plan?
They have to disable it. Otherwise, who in their right mind is going to pay for something when there's software already on the phone that allows you to do it?
I guess I'll just be sticking to PdaNet. Nice try though, VZW.
Yeah, darn. Hopefully the geniuses here can find some way to reenable built in wifi tethering so that vzw cant tell that its being tethered. I want wifi on my ipad
does this mean there is a high chance this phone will be un-rootable? because of http://code.google.com/p/android-wifi-tether/
2.2 source code may be released to the carriers but they can change it however they want to fit thier hardware and needs.
So if they want to take out the free wifi hotspot capabilities in 2.2 for the X or other devices and still charge for wifi hotspot capabilities with 2gb caps for 20 bux then guess what, they can.
PDAbnet may do wifi tethering but that is different from wifi hotspotting to multiple devices
remember that once rooted you can flash different roms and install any apps to your hearts content

This doesn't really have any bearing on whether the phone will be unrootable - IMO every phone is rootable, it is just a matter of finding an exploit... Hopefully this phone will be easier than the last one I had (Droid ERIS :-/)
This is not correct. The Milestone has been rooted but no access to the bootloader has been had meaning no custom Tom's.

Here is a few things to keep in mind..
The Verizon 3G app is infrastructure, thus it works with things like PSP and Nintendo DS, which is why i keep it. The Wireless tether apps are only ad-hoc for now.
From what ive been told, the verizon app loads a different firmware before running.
Now, what verizon can do and has done in the past, especially on windows mobile phones, is take out a feature like wifi hotspot in an OS, and put their own in its place.
do NOT be surprised if VZW does the same thing with 2.2 and yes, it is 20 a month for a measly 2gb on the hot spot app, but wireless tether is unlimited for 30
this is why i ONLY use the hot app for PSP and DS and the rest wi-t for root
not to mention, i am not even sure if the 2.2 is ad-hoc or infrastructure.. anyone know?
This is how the USB Tethering works for Verizon's 2.2 FroYo build, and I'll safely assume that it'll be the same for WiFi:
When you connect via USB Tethering, the phone directs you to a Verizon webpage (https://dunsp.vzw.com/selfProvisioning/SelfProvisioningServlet) which informs you of the package costs, and gives the phone number to add the package.
Interestingly enough, this only occurs if you tether it's 3G connection and not it's WiFi connection.
You may wonder why you'd want to tether a phone's WiFi connection via USB.. well.. personally I just pay for the Boingo mobile hotspot ($7.99/mo), which will work on my iPad or Droid, and if I need to use my PC, I tether my Droid's WiFi to my laptop. Saves $9.99/mo.

Wifi tether, infrastructure mode?

So I currently own a Thunderbolt on Verizon as well as a wifi only galaxy tab and a wifi only xoom.
I also have a G2X on a 2 week trial. I was going to transfer me and my gf's phones over from Verizon.
I have my G2X rooted already and I have wireless tether installed. It works but my Xoom and my Galaxy tab won't recognize it. I'm assuming this is because it's running in ad-hoc mode and not infrastructure.
If this something that can be changed with kernal upgrade or custom roms or will this phone forever broadcast ad-hoc? This is pretty important to me as it's one of my primary purposes for switching to tmobile. (4g in my area vs none for verizon as well as battery life.)
all the 3 version is infrastructure mode the 2 version is in ad hoc. try it out should work not sure yet tho. http://code.google.com/p/android-wifi-tether/downloads/list
I feel like a tard now actually. I'm so used to having verizon I didn't realize that T-Mobile didn't take out the stock android mobile hotspot app.
Does anyone know if t-mobile makes you sign up for a tethering plan to use it? I was able to fire it up and connect both my Xoom and my galaxy tab just fine.. just don't want a suprise in my bill.

Just use it.
If you got error page, you simply add tethering option or just change browser agent (but I don't think you'll get in trouble if you tether with Android tablets).
As long as you have an unlimited data package youll be fine...they have a 2gig & 5gig. Once you go over those limits it will still work, just not as fast as before you went over the data cap. No issues with mine tho, my hotspot works fine with various devices

It's not an app, it's in the wireless network settings. Same place as wifi-bluetooth and all that. Just a check box to turn it on.
Funny story about the wireless tether for root users app.
So when I posted this that it will only work in ad-hoc mode, I found a workaround for my xoom to connect before I realized there was built in hotspot. The built in hotspot works great and it's infrastructure mode, but like my thunderbolt and droid x before it, won't stay connected in my office for some reason.
I tried the wireless tether program and low and behold it stays connected firmly in my office. Must be something about it being ad-hoc because all the infrastructure mode tethering methods I've tried will not stay connected in my office.. must be some intereference or something.

Wifi tethering speeds are slow.

If i run speedtest app on my phone I get 10+ down but when I use any of my laptops I get 1.5 if I am lucky. Why is this? Do other phones have this problem? Ive tried wireless tether and barnacle.
http://www.speakeasy.net/speedtest is more accurate. Pull it up in your phone browser.
Speakeasy on the phone shows 25 down more or less across 3 tests. My laptop wifi tethered to it using barnacle or wireless tether are both giving me about 1.5 down.
Does anyone get good speedtests tethering? Or are we all getting the same result?
I even tried verizons hotspot tether which still works and its not any faster.
So frustrated. I bought this phone (and Verizon) only for tethering.

wow that is exceptionally weird. I do not experience that at all. I actually did a test between wireless tether and the verizon apps on the 7th deciding if and when i wanted to pay the unlimited 30 and saw faster download on wireless tether but very slightly faster upload on the verizon.
try toggling the radio or just do a nice reset of the phone for test purposes
Yeah, I haven't had any problems either. I get 15mbps+ tested on my laptop using wireless tether 2.0.7, which are typical speeds for my area.
Edit: I'm at work, where I only get 3G service and just ran the speakeasy test. Again, on my laptop over wireless tether 2.0.7 and got just over 2.5mbps.

internet tethering without root phone and undetectable by carriers

just downloaded it tonight. runing great.got 4g speed tethering,,,,,,,,,,,,,
Android hacker Koush makes mobile internet tethering undetectable by carriers
http://www.slashgear.com/android-ha...-tethering-undetectable-by-carriers-02205425/
Sooo what's the difference between this one and all the other ones? Currently on my phone I have both the Wired Tether and Wireless Tether apps (neither available on the marketplace but easy to find in the right places). I've never gotten a message from ATT once about tethering - and I do it more often than not, using just the Wireless Tether app. Averaging 4 GB a month total data (tether and legit non-tether data combined)
Kudous to Koushik for getting a workaround like that, but the necessity of a laptop kind of puts the kibosh on it for me since I'd use the hotspot feature for tablets mainly.
^^ agreed. wifi tether trumps usb tether. main reason i rooted in the first place. but good to know that non root options exist.

Tethering A Computer vs. Tablet

Tried to ask this in the general forums and didn't get an answer, wondering f you guys could help. Got an s3 to keep my unlimited data. Reading it says that Verizon can tell if you tethering to a computer due to TTL packets. I don't know much about networking but reading it says that windows computers while tethering push a value of 124 or 128 packets unless configured while android devices have a value of 64. The thing is I never tether to my computer only my tablet. So can I safely go nuts tethering to my tablet as if it was my phone due to it looking like I'm using my phone or am I way off and can Verizon tell I'm tethering and using my tablet. I really just want tot tether the hell out f my tablet when I need it. Anyways as this is XDA can I hide it safely? I have an unlimited data plan so the whole OK to tether thing since that lawsuit doesn't apply to me with this.

I don't know about the packet size issue you mentioned.
Otherwise, I have read that if*your Verizon tethering indicator turns on or your usage suddenly goes quite high for a month or more, they might suspect you of tethering without a plan and look into it. It's also said that apps like PDAnet make it very difficult for the service provider to figure out if you are tethering or not - regardless of what you're connected to.

VZW can no longer block tethering on 4g phones. Due to FCC saying so. Simple Google search will fond multiple articles.
There is no restrictions on unlimited versus tiered data plan. What counts is that you have a 4g phone. Check out this article ans the tether away.

Rocking T2 on the unlocked VSG3!
I've read differently. It sounds like if you have an unlimited data plan you can only use that data plan for a single device meaning that you can't tether the unlimited data. I read multiple places that this is part of the terms of service and it doesn't apply to unlimited data plan users... M
aybe somebody can clarify this for me because it would be great to use my unlimited data for tethering when on vacations.

Tethering
Its like not paying you bill. You get a warning. You can always deny it or ignore it. Modern PDANet if thats what you are boing to use has some countermeasures. At least 2 I think. Don't know if they are effective. You can just use Orobot to tunnel your traffic and I'm pretty certain that would work. I don't know what you plan to do but I wouldn't go download something shady from some torrent site though. Web browsing and getting email is probably fine.
I've been tethering my laptop to my phone since I first figured out how to do it with the Droid X. Meaning basically since I rooted it and found a decent tether app. Out of 5 people on a business share plan(business version of family plan - add a line for 9.99 etc) I've always had significantly highest usage. 5 gigs at a bare minimum, and not once has verizon figured out I'm tethering.
I honestly dont think they can really tell if you are or arent tehtering. 4g or 3g.
Curious, is Verizon still charging people today who were paying before the ruling? Is it possible now for me to use built in hotspot instead of wifi tether, regardless of whether or not i am on a custom rom? I am using latest synergy atm with wifi tether, i should have no problem using built in right?

I believe you can if you turn it on through the notification toggles...Why tho? The WiFi for Root Users is a lot more customizable...

atm no. the software is still there to keep you from doing that. IF you root, the world is your oyster though... and they aren't actually allowed to do anything to do. They just aren't rushing to open everyone up to free hotspotting.
