V-M200 disconnection.

I'm experiencing a major issue with a V-M200 brand new AP.

It is physically located just outside a room, beyond a glass-wall. There are 5 laptops connected, all them are 802.11n compatible and the AP is set in order to work on channel 10. The laptops are obviously in the room but they are in line of sight with the AP and the signal strenght is in all the cases "Very good" (this is also confirmed by the AP - Signal is -55db and SNR is 36). The problem arise at least 5 to 10 times a day: the connection is lost (and conseuentially Outlook and other real-time apps stuck).

If I browse the System log, I continuosly got messages as follow:

Is someone else affected by this problem?

Is there anything I can do on both the AP or Laptop side to have my problem fixed once forever?

Any help or suggestion will be highly appreciated.

Kind reagards.

Re: V-M200 disconnection.

bummer you got no response - I deployed 10 of these in my school in December to see if we want to do a full Procurve network revamp this summer (bid was about $130,000). This has just started happening. And when it happens, I have very little ability to connect to the AP with the web interface - it is super slow. Sometimes I am able to login and restart the AP, and that solves the problem temporarily. 

All 10 are identically configured, but only a few have had this problem. Some have almost 80 days uptime since last reboot.

Needless to say, the whole project will be reconsidered if this does not get resolved quickly.

Anyone?

Re: V-M200 disconnection.

I have experienced the same issue.  Interestingly, some devices seem to play fine with the AP, others will connect and then drop their connections as soon as I start moving larger chunks of data.

Re: V-M200 disconnection.

It is slow. it throws out clients. Web pages hang, crash.

Some EliteBook users can use it, but it is very slow on surfing.
but that the web pages crash or hang

It does not work for Lenovo, Acer, Dell, Dell Alienware computers, not iPhones.
Here, clients evicted from the wireless network all the time.

We have tried all different configurations. From low security to high.
We have tried all compatibility modes. ABGN.

Maybe it works fine without security lol.

This is the worst AP we have ever used. it is less a SOHO Cnet AP for home use.

With the price of this, this is a robbery. Price US $220 ex local TAX

New firmware now, or take them in return! Shame to be a corporate product!

Re: V-M200 disconnection.

I have a v-m200 now for 1 hour and have just reconnected the power for the 10-ed time.

 

ping 192.168.1.1 (the default is working)

connect to the website of the AP works sometimes

try to setup the AP will crash it and you are only able to poweroff/poweron the device

Re: V-M200 disconnection.

The posts in this thread describe an issue which is clearly neither expected nor desireable behavior. If you are experiencing this issue, please log a case with HP Networking support. It is my understanding that a fix is in the works. Sometimes, logging a case provides key data points or other information that speeds time to resolution. Other times, it might allow you to participate in verification of the fix. At the very least, logging a support case will ensure that you are notified when the fix is available (sometimes even before the fix is publicly posted).

 

No one likes to experience an issue that creates so much frustration - but calling support and partnering with us toward a resolution is win-win.

Re: V-M200 disconnection.

We are a school district in Hawaii

 

We have also invested a  great deal of money in these units.

 

They continually drop the clients and now...with our new Cisco switches, will not function at all!!!!!

 

Thanks for your suggestion about entering a support ticket....I will do that RIGHT NOW!!!!!

Re: V-M200 disconnection.

 

I had the same problem with clients being connected but not passing traffic. The log would show the disconnection as posted above.  It was sitting near an electrical outlet and on top of a metal vent.  I do not know why it matters because it sure did not matter with my old equipment but after I moved it the problems stopped. It now sits far away from the electrical wiring on top of a cardboard box not touching any metal. I had to power cycle it once or twice a day before and now I have gone three weeks with no problems. Also the log has cleared up after the move.  I can't say for sure this will solve your problems as well but knowing how frustrated I was with the product I figured I had to share this with the group.
