AirCard internet connection stops working after being connected for some random length of time.

AirCard internet connection stops working after being connected for some random length of time.

I used the AirCard Watcher program to connect. I am using the PCMCIA/PCCard Sierra Wireless AirCard 860, but I know a person with different AirCard with another provider is having similar problem (I think the other person is using Verizon, and has AirCard 595).
Problem:
  After being connect with the AirCard for sometime (seems random, maybe several hours or days or so), the internet stops working. I cannot ping [ping nameofsites- Ping request could not find host nameofsites. Please check the name and try again], I cannot telnet to any external site, etc.
  The watcher program still reports connected with good signal (The other person experiencing similar problem said it will eventually report it as disconnect after some hours, then she has to manually press the connect button), but only the TX byte counter goes up (maybe this only indicates number of bytes send to the card, and not data actually send out successfully). 
  I have to manually press disconnect, and press connect, to get things working again. This is a big issue, because we are using this for automation on an unmanned computer. (I do not get the same problem, if am connected via wired-cable.)
 
Anyone else experienced this? What is causing this problem? What is the fix? Is there a program that will programmatically disconnect and reconnect, after it detects this condition?

Re: AirCard internet connection stops working after being connected for some random length of time.

The newest verion of the ACM now includes new driver support for the Option Express Ultra blah blah blah.  But the good thing it also includes some updates from Sierra itself to help with the random dropouts and other system compatibility issues reported.  Wish I had the actual details of the software but, meh, I will leave that upto you all.

Re: AirCard internet connection stops working after being connected for some random length of time.

I have seen this many times also, and i think one of the causes is when you get yours or someone else cell phone to close to the aircard. Or other radios at the plant get to close and interfere with the aircard signals.
 
Also so as this is not to be always connected i am sure that the software/driver will auto disconnect if connection is not be used for some amount of time.

Problem: AirCard connection stops working after some times

Bottom-line:
For some of us, this continues to be a problem (even with latest updates). There are some flaws within the service, system, or electronics. Since the service provider and manufacturer can’t figure this out, they should at least implement the following temporary fix.

 
Proposed Temporary Solution: Have an option in the AirCard Watcher program to auto reconnect when this happens. (And provide command line utility so any automation process can connect/disconnect the Watcher program when this happens)

Re: AirCard internet connection stops working after being connected for some random length of time.

I have the 875U card and it started doing this also around January. It seems to be getting worse on a daily basis, this gets very old. I will be in the middle something and the internet freezes up, have to disconnect which will take 10 minutes sometimes and then reconnect which take a while also. I have done all of the above that has been mentioned as the others have and it continues to do this! I am running on the EDGE since 3G is not availible in my area as the AT&T rep told me it would be by the first of the year when I bought this thing. Should have known better! If I could get out of the contract without having to pay that high fee I would since I was basically lied to about 3G.

Re: AirCard internet connection stops working after being connected for some random length of time.

 Well I seem to have mine fixed and running pretty good now, there is a few setting changes that have to be made to get it there.
see my last post in real world edge performance for the steps. Ive experimented and installed clean fresh operating system with the new ATTCM  without doing any changes I get the random lockup issues, once I do the settings it works fine. It will still hickup every once in a while but just stop what your doing wait a minute and she starts working again.
 Still would like to know what changed a couple months ago to cause it.
