USB Tethering Help

I am trying to setup USB tethering on my phone. Instead of bringing the old threads back from the dead I just linked them below.
First lets get the obvious stuff out of the way.
1. I do use wifi tether, but if I want a file to download all night this isn't a good solution, battery goes dead after about an hour hooked up to the wall charger.
2.PDAnet - this works well if you have time to constantly monitor the connection or for casual surfing on a dead or close to dead battery, it randomly drops and doesn't reconnect on its own.
3. AziLink - The OpenVPN thing ruins this option, to big of a pain in the butt. Having to install an run in a VMAppliance.
I have looked at the other 2 options for USB tether. -
The Race condition between Mobile Network Connection and Mobile Network sharing here I just can't seem to "beat the clock" the network always connects first and gives me error 67. I was thinking this may have been patched since the thread is old, pre-update.
And this other one no one can seem to get to work.
So what I want to know - Does any one actually have a working USB tether option? I more or less want to be able to hook my phone up start a download and walk away with out having to worry too much about the connection droping (like pdanet).

I find that charging via usb doesn't heat up the battery as much, and it lasts longer.
but this is relevant to my interests

This thread makes me really very thankful for my 40 dollar a month roadrunner high speed. 2 mbps and I don't have to worry about anything.
Ps I am not an employee of time warner cable nor am I receiving any compensation for this post

AT&T has great DSL, for low prices available in most areas.
P.S.:
DirecTV and AT&T are in no way business partners, and I do not get compensated if I convince you to sign up for their services...
Even though I'm supposed to...
****ing payroll.

I cant get anything except the "race" one to work. I have gotten it to work with every ROM ive tried as well. Usually takes a few tries and you eventually get the feel for the timing.
Very difficult to explain the timing . My internet went down one night and i did it desperately for god knows how long until i figured it out. I guess it takes a serious catastrophe like network outage for 10+ hours to make you desperate enough to fail, repeat, fail, repeat...

I figured out if you hit it to soon, it doesn't work, and if you hit it too late it doesn't work.

I don't get either of these services up where I live, and I absolutly refuse to deal with Comcast. USB Tether has always been my primary access point until WiFi tether which is just not near as helpful since my battery goes dead so quickly with it.
I got the race condition to catch one time last night in an hour and a half of trying, but when it did work my computer wouldn't actually show a network connection.
Just to make sure, when I turn on MNS it shows up as "HTC RNDIS Driver". Is that what everyone else is getting?

That's because USB charges at 500 mA, half of the wall charger's current.
When using WiFi tethering, USB charging cannot keep up with the current draw, and the battery will be completely dead in an hour or two. I've taken to plugging the phone in the wall charger, turning off the screen, removing the back cover, and placing the phone face down while doing WiFi tethering. This keeps the battery from overheating.

I can go all day with wifi tether via usb charging. I download a lot too

Really? I definitely can't. Lucky you

If I connect to wifi tether and let the torrents go, plugged into the wall I am lucky to get a little over an hour. Plugged in USB isn't a whole lot different if I start with a full battery. Just browsing the web I can go a few hours.

Good UPS for a desktop?

Hello guys, we recently got our first imac and the store threw in the cheap APC 350v UPS unit with the purchase. (the power went out and the imac was alive for around 15mins which is whats advertised on the box)
Now I want one for our windows desktop which has a 350 psu, I believe it consumes more power than the imac so I'm thinking of getting a bigger one for it, which do you guys recommend?
also I would like to ask something power related, before getting the mac I had a dell desktop (lasted 4 years and then had a mobo failure) and I remember that if I touched its case, I would receive a slight electric shock.
same thing happened with the imac yesterday, as I reached to plug my external hard drive in the back, I received a slight shock when my chin touched the aluminum. should I be concerned about this?
Sorry for asking too many questions

By UPS do you mean PSU?

UPS - Uninterruptable Power Supply (i.e battery backup that takes over when mains power goes down)

I'm not sure about the shock.. but I use this UPS in my office, and I've never had an issue.. Then again my power has only gone out a few times, for no more than 10 minutes.
CyberPower Standby CP550.
I'd post a link, but I can't yet.
Never had any issues though, and neither have any of the other properties using it. (Which is why I bought it..)

Ohh, my bad. Completely misunderstood! Thank you for the enlightenment.

numeric-mischief said:
IF you're looking for a UPS with more run time - look into the volt amp (VA) rating of the UPS. Some of the best value UPS's out there are the CyberPower Adaptive Sine Wave UPS - CP1350PFCLCD UPS 1350VA or CP1500PFCLCD UPS 1500VA. There are a couple reasons why these are superior - 2 usb charging ports which are battery powered, automatic voltage regulation (over/under regulation) and they produce pure sine wave which is compatible with the higher efficiency power supplies (PSU) (ie 80+bronze,gold, or platinum) which means you don't have to worry in the future about if your psu will work with your UPS. I use them with my home built PC's as they were not compatible with the cheap 1500VA APC I had previously (black friday deal from a couple years back).

I'm not 100% sure on this, but I'm pretty sure you have no freakin idea what you're talking about... There's no such thing as a voltamp, it's called a watt.
Then again, not sure. Maybe UPS companies made up something to pawn off their crap that has no valid use in this day and age.

There is a slight difference
http://en.wikipedia.org/wiki/Volt-ampere
UPSs are only meant to keep power running until the hardware has safely shut down, not run instead of the mains.
I have one for my PC upstairs, it's an APC750 if memory serves.
I use them in a professional capacity with work, and unfortunately many people who install them don't know how to configure them or connect them up.
So many client sites I've been to where they have things like monitors plugged in, or don't have the switch connected to a network controlled UPS so it can't then tell the servers to start shutting down.
Basic ones will just have a serial or USB connection to control one computer, telling it "power's out, start shutting down now"
You want to time how long your computer takes to shut down, then set the UPS to take a few minutes longer before killing the power to it's socket.
If you're prone to minor power outages, where it cuts out for a few minutes and then comes back on, then with the decent UPSs you can configure them to delay the shutdown message for longer.

My Nexus 7 fizzled and died!

I was using my Nexus 7, playing a game. It then static-screened and hissed for 2 secs and then died! It was charging through PC USB.
It won't power up anymore.
WTH?

You may have overheated it. Wait a few hours and try again. also, depending on the USB charging, the charger may not have been able to keep up with the battery drain of the game and it shut down for a low battery. Use the OEM charger whenever possible.

If the device actually made a "fizzle" sound then I recommend sending it in for a replacement. Sounds like a battery leak. Was it overclocked?

I had the same problem yesterday, my battery was very low and I was using it while plugged-in a PC USB.
I was playing reckless racing, i left it on the desk for awhile when I went back to my PC. the device was on, but all of a sudden it fizzled and static screened.
I freaked out and unplugged the USB. then the device shut-down(turns black) immediately. The device was a bit hot on the back bottom. I tried to turn it on, NO GO. I plugged it in the OEM charger, NO charging screen. tried turning on, still no go.
then i look in xda. and found out someone said to hold the power button for 30s.
So, the device was plugged in OEM charger. I sat it there for like 5 mins first. then try to do the 30s.
It boot up again on like 35, or 36 second i counted.
I bet it was a low battery problem, since charging it from a PC doesn't provide enough power.
The method solved mine, and i hope it solved yours too.
Gd luck!!

I meant to say a I heard a fizzling sound when it static screened. Almost like the sound you hear with TV static but more... fizzy? :silly:
lol

If you heard a fizzle I'd definitely still send it back in for RMA, better safe than sorry down the road.

just looping the sound file from the game before shutting down not a issue. watch that battery icon in the future.
playing nova 3 on full 1600mhz oc N7 did the same on a freeze and reset. (; have to find the settings that work right. nova 3 1500mhz with the gpu oc at 500 screams and is stable on my N7. spiderman became a fun game after the kernel flash.

Just to say it again - plugging the Nexus 7 into a PC USB port will not keep it charged during high current usage.
If you drain the battery completely - don't expect any display until you have charged it for probably an hour.
Funky noises from your game when you flatline the battery is no cause to return it.
Use a dedicated charger for game play, preferably the one that came with it.

Didn't fizzle here, just turned off and no matter how long I held power button or left charging on mains connector or on PC, the tablet was completely dead. Returned to Argos and got refund and now waiting on another Nexus 7 to be delivered but via Tesco direct this time.
Fingers crossed this one lasts a lot longer than the hour the first one did

I had this exact same problem except mine wasn't plugged into anything and my battery was not near empty. When I finally got it booted back up it was at 27% so for me it wasn't low battery. I only ever use the charger that came with it - unless I'm connecting it to my laptop for a few minutes to transfer files, etc.
This is my second Nexus 7. The first one got returned because it had problems with the touchscreen on occasion. It actually did do this static/fizzle/crash once or twice as well.
I wonder if the static/fizzle/crash issue is being addressed in hardware and/or software with a newer version of either one?

Pls tell me Asus representatives are reading these threads in xda. I can see lots of problems with the device. Google should take serious actions on this

That would freak me out my dizzle...I hope my Nexus doesn't ever fizzle.

Maybe, but I had more than a quarter of my battery left and had very similar symptoms. I think it might be related to heat generated by gaming. Maybe with low (but not out of) battery, maybe not. The touchscreen issues I experienced on my first N7 seemed to only occur after hard gaming. Maybe there's a heat dissipation issue? (Wild speculation)

Mine did exactly the same last week, thought it had died altogether but holding the power for 45 seconds sorted it.

I need help too.
My N7 turned off when the battery ran out. So i plugged to charge through PC USB and immediately when that great charger icon apear in the screen i pressed the button power, and so it go black. No more signals. Dead... No charge, no turn on anymore.
I tried to hold the power button for 30s a lot.
I opened the N7, unpluged e pluged again the battery. Nothing.
I let it charging, in the OEM charger, with OEM cable, all the night, for more than 12 hours. Nothing.
And it has a "fizzle" sound. It can be heard better when its open.
When i disconnect the battery the sound stop. If i connect the charger, even without the battery, the sound come back.
When i hold the power button for 30s the sound stop for about 3 seconds, and then restarts.
The Windows manager device recognizes the N7 as a weird "APX" (image attach).
In from Brazil, so for now will not be easy to return to google.
Any ideas?
Thx in advance
---------------------------------------
Update:
I discovered that the unit does not appear to be charging.
Before, the OEM charger became a little hot, and now nothing.
I instaled today the program "Asus AI charger" that lets you charge a ipad in USB, and the icon charging do not apear when i connect the N7, only when i connect other devices.

So mine just fizzled and died not connected to any power source. I was at 9%. It was running a bit warm but no where near relatively hot. Will update...

using own AC

I don't have any choice but to power it on the AC. It was connected at the back of my receiver (Yamaha) but unfortunately the USB on my receiver is in front but I'd rather use its own power for a clean look. The problem right now is the chromecast is always on. I can see the white led is always there. I'm afraid this will not going to last if its always on

I don't think you will have a problem with it being always on. If you are really concerned, you could always get one of those Green power strips that turn off specific power ports if the main power port isn't in use.

I agree that this shouldn't be a concern. Most modern LEDs running at standard intensity 24/7/365 should last 8-11+ years. You should be asking yourself if you expect to still be using your Chromecast over a decade from now. Also: When was the last time you saw a consumer electronics device in use with a dead LED?

I have a tuner/amplifier that I still use to power my small Bose speakers that is from the early 90s. The LED panel on the front is burned out so its no longer useful to tune radio stations, but the amplifier still works as well as it did from day 1. Amplifiers are hundreds of $$ for one with similar wattage, so i have continued to deal with its problems.

The manual says nothing about overheating causing damage to the device.
All that the manual says is to unplug it (to let it cool off) before removing it. Heat shouldn't be a problem.

Does your receiver have a 'switched' outlet on the back? That outlet will go on/off with the receiver. You could plug the Chromecast into it.

Quick Charger question

I have noticed that when I turn off the power with the phone plugged it, the phone takes about 3-4 seconds to realize that the charging has stopped. There is almost a lag between when the power to the charger is cut and when the phone realizes it. Is that normal?

If you pull the plug on many electrical items in your home, you will always notice it takes a few seconds for the power light to go out. Its normal behaviour for electricity.
Its the same with water actually. If you turn the water off outside your house, then run the tap, all the water that is still in your pipes will come out the tap for a few seconds.
