Flex 2 14 periodically disconnects from the network on Wi-Fi.

My brand new Flex 2 14 periodically disconnects from the network on Wi-Fi. This is pretty unacceptable. Other PC's in the house are not experiencing the problem, so it's difficult to blame the router.,
I have a Broadcom 802.11N Network Adapter device with driver version 6.30.223.201, which is the latest on the Lenovo site. I am running Windows 8.1, as provided on the system. I've installed Windows updates and some other software, but have not otherwise changed the OS.
I have seen other users with similar problems, but no fixes for Broadcom.
Any ideas anyone? May be a "back to lenovo" thing.

Go to Solution.

I called Lenovo Tech Support and they had me try something that seems to be working. Apparently there are *two* drivers available for the Broadcom 802.11n Network Adapter: one published by Broadcom, one published by Microsoft. My system *was* configured to use the Broadcom driver, Lenovo Tech support had me change to use the Microsoft published driver. I have not had a disconnect since.
To change the selected driver:
0. Make sure you have the latest drivers from the Lenovo support site installed.
1. Launch "Device Manager"
2. Expand "Network adapters"
3. Right-click on "Broadcom 802.11n Network Adapter" and select "Properties".
4. In the properies window, select the "Driver' tab and click "Update Driver..."
5. In the update window, select "Browse my computer for driver software"
6. On the next page, select "Let me pick from a list of device drivers on my computer"
7. On the next page, you should have a choice of selecting from one of two drivers. Select the one from *Microsoft*.
8. Click "Next" and complete the driver install.

SOLUTION to your HP printer going offline and/or constantly disconnecting from the network

If you are having a problem printing, scanning or faxing with any HP Printer because of it going offline and constantly disconnecting from the network, here is the fix!
I figured this all out after many unsuccessful attempts with HP Support, my Internet Service Provider and various troubleshooting tasks including reinstalling HP software over and over and over. Well, through self teaching on the internet and 6 grueling months of research, I FINALLY figured it out. OMG! I am a Paramedic (not IT) and somewhat computer literate but by far no expert. I here all of you! Nobody seems to have the answer but I am 97% sure that I do. Either way, please reply back and let me know that this did in fact work for you! :-)
It doesn't matter if your printer is installed wirelessly or wired. Don’t worry about reinstalling your software, no recycling your printers’ power or your Router/Modem. The reason your printer is unstable on the network and continues to either go offline or disconnect from the network is NOT because the software is glitched, it’s not a firewall problem per say, it’s not a router problem, there isn’t a problem with your power cord, it’s because most networks use a “range” of IP addresses and for security purposes, it sort of “cycles” the various devices’ IP addresses to decrease the chance of an attack. A printer is no threat but the “network” doesn’t possess human intelligence so it doesn’t know this. Below are my step by step instructions on how to basically make your printer hold its IP address (static IP) instead of changing back and forth through a cycle therefore dropping your printer off the network or disconnecting.
Funny, if you are someone who has had items in your print cue, they won’t print, and you turn your printer off and then back on and suddenly your documents print…well, join my club. The reason this works is because when you first turn on the printer, it starts with the same IP address before it cycles. If you are someone who sits there for a while and suddenly your documents print without you changing anything…this is because through the IP cycle change, it hits your printers IP address and the network will allow it to print. Not very funny, I know. It took me forever to figure out why my printer would print sometimes but not all the time. Since I figured this out, I can SCAN, PRINT and use all of the features of my installed HP software such as HP Solution Center, Photosmart Essentials.
On your printer, go to menu/setup/network and press OK. Inside the network menu, print a "network configuration page" so you can see the IP address and other settings for your printer.
Now, go back to main menu on your printers’ screen. Or you can go to your web browser and type in the IP address using the decimals too and this will take you to your printers’ web page. Choose: setup\network and press OK. Look for IP settings and press OK. Choose "manual" instead of "automatic". Enter the IP address there manually as well as the default gateway which you can see on the network configuration page that you printed earlier. Note: If you manually set the printer's IP, make sure that it is outside of your router's DHCP range. Otherwise you may run into an issue with duplicate IP's on your network. (If you don’t know how to do this, write back and I will explain). Don’t forget to click “save changes”. Now, restart your computer and print anything you want. :-)
A trick I often use with printers in DHCP networks:
In Printers and Faxes right click on the printer and select “properties”. Click add a new port. Choose standard TCP/IP port configured to the printer host name. Read the hostname from the printer's network configuration sheet.
Using my method means that you always connect to the printer even if its IP changes (which may happen with dynamic configuration). This does not jeopardize your network security. It just tells your printer to stay put and stop traveling the IP address highway. :-)
This question was solved.
View Solution.

The DHCP range is the range of IP addresses the router hands out automatically as devices join the network. The DHCP range is determined by the router and each brand has a range set at the factory (that can be changed by you).
Your D-link's DHCP default range is 192.168.0.100 to 192.168.0.199. So, outside the DHCP range is .2 to .99 and .200 to .254.
Attached is a handy cheat sheet.
You can change this range by entering the router's settings page - type the router's IP address into a browser, enter the login info and navigate to the DHCP settings area (varies based on router, hunt around).

Oracle Personal Edition (disconnected from the network)

Hello everyone,
I have oracle PE 10.1.0.2 installed on my laptop (running windows xp pro sp2). I have the laptop connected to the network most of the time. Yesterday, I was trying to access my database while I am in the coffee shop but I couldn't. I was getting a "no listener" error from the application I am using. I took a look at the running services and I found out "OracleDBConsoleorcl" and "OracleServiceORCL" did not start. I tried to start them. But I was getting a type 2 error. tried to reboot. no good
When I connected my computer to network, I was able to connect to the database from my application and from the enterprise manager.
I searched this forum and I found out that I need to configure a loopback adaptor if Oracle DB is installed on a DHCP computer. In my case, I am disconnected from the network. Would a loop back adaptor fix the issue? Would it cause any problems when I connect back to network? In another word, would the database listener and OracleServiceORCL services work if I am connected and disconnected from the network?
Thanks for the help

I do not have Personal Edition, but if you can a check, make a copy/backup, and then change the entries in $ORACLE_HOME\sysman\config
$ORACLE_HOME\sysman\config\emoms.properties $ORACLE_HOME\sysman\config\emd.properties
and any httpd configuration files in that directory.

How to resolve "The server is unavailable and could not be accessed. The server is probably disconnected from the network." error in Sharepoint serach crawl.

Hi all,
I have created a content source in Search service application for a particular site collection "http://spwebapp/sites".
I performed reset crawl index of Search service application and then performed a full crawl.
But i get errors on running crawl on this content source for most of the files. The error is "The server is unavailable and could not be accessed. The server is probably disconnected from the network." Though the site is accessible.
But before performing reset index the crawl was working fine on this content source. Crawl is working fine for other site collections. Only one site collection is facing this problem. Please let me know if what I can do to resolve this error.
Thanks in advance.

Are you seeing any error messages in the URL related to the Gatherer? And in your content source, are there any site URLs that are no longer active or do you have any crawl rules set up that might be affecting access to the site collection?
I've seen this happen for a variety of reason, SSL issues, proxy issues, permissions issues. The Eventvwr and ULS logs should help you narrow down the real problem.
Sometimes this is an issue because the indexer and the site are sitting on the same box, you could try doing a disable loopback check to see if that resolves the issue and if it does then go through the hassle of setting up a specific LSA :

In my small office ethernet network all of a sudden one of my imacs cannot be connected to. It can connect to all other computers and can access internet, but as soon as someone tries to connect to that mac, it disconnects from the network. Any ideas

I have a network of 9 macs that connect via ethernet and a router. All of a sudden one of the macs cannot be connected to. It can connect to all others and the internet, but no one can connect to that one. I have appletalk active and file sharing on, but everytime someone tries to connect to it, it is not on the network. Additionally, the personal file sharing keeps turning off even though I have it locked. Any ideas?

Hi orangekay
not sure where you got the idea that I have
bizarre encrypted filesystem plugins and scripts you have manipulating them all the time
because I do not have any such running, just normal Applescripts that do tasks that could be done by hand.

Why do I continually get the error message "iTunes Match could not be updated because you were disconnected from the network during processing"? What network?

Over the last 4 or 5 days, I get this message every time I open iTunes. I'm not sure what network this error message is talking about. Any ideas?

Hello FredJay,
Thank you for contacting Apple Support Communities.
iTunes Match needs a network connection to work, either Wi-Fi, cellular or wired. See the following:
Make sure you have an active Internet connection
Be sure your computer or device has an active Internet connection by loading a webpage using Safari or another web browser.
On an iOS device with cellular support, if you are not on a Wi-Fi network, try enabling 3G cellular data1 for iTunes Match.
For iOS 6, tap Settings > iTunes & App Stores > Use Cellular Data > On
For iOS 5.1.1 or earlier, tap Settings > iTunes & App Store > Use Cellular Data > On
1Fees may be associated with downloading over cellular networks; contact your wireless carrier for details.

CRIO disconnects from Ethernet network and stops responding to pings

We are running a cRIO application that periodically disconnects from the Ethernet network even though the VI continues to run on the cRIO.
The application has two parallel loops. One loop reads data from the FPGA and writes it to a RT FIFO. The second loop opens a TCP connection to a remote host, reads data from the RT FIFO, and transmits the data to the remote host. We have instrumented each loop to send messages to the serial port that indicate their status. When the cRIO disconnects, both loops continue to send their status messages to the serial port. The first loop happily continues reading data from the FPGA and writing it into the RT FIFO. The RT FIFO overwrites the oldest data when it fills up to keep it from overflowing. The second loop reports a TCP write timeout (tcp write error 56) around the time that the cRIO disconnects, after which it closes the existing TCP connection and then repeatedly tries to open a new TCP connection (each attempt times out after a 5 second delay).
All that appears normal and usually the connection is automatically restored. Occasionally, however, the cRIO is not able to re-open the TCP connection. Furthermore, the cRIO stops responding to pings from the remote host. On two occasions, the cRIO was finally able to open a new connection after 30-40 minutes. Other than that, the only way we've found out of this dilemma is to reboot the cRIO.
The frequency of the disconnects and the time before they occur doesn't seem connected to whether or not the cRIO is set to run the application at startup or if the application is run via an interactive VI window on the remote computer.
It is possible that the disconnects have something to do with which computer the cRIO is connected to, as the problems seem to happen much more frequently (often within minutes) when the cRIO is sending data to a laptop running Windows XP, but it can run for hours when sending data to a rackmount server running Windows Server 2003. Everything else (the speed and size of data being sent, the ethernet hub and cables, the VI running on the remote computer) is the same.

We're done most of the testing with a 9014 real time controller and a 9104 chassis. However, we've also seen similar behavior with 9014/9103 and 9102/9101 combinations.
The 9014 cRIO normally runs at around 50% CPU usage and less than 40% memory usage when the data is flowing steadily. The RT System Monitor did not indicate a spike in either before the cRIO disconnected.
Measurement and Automation Explorer is not able to connect to the cRIO after it disconnects. We tried pinging the cRIO from a different computer, but that also failed.
After disconnecting, the cRIO sends error messages to the serial port while trying to open a new TCP connection. It reports an error 56 (time-out error) 3 or 4 times (for a total duration of 15 or 20 seconds) and then reports an error 42 (generic error) at least 10 times per second for 18 seconds, and then switches back to 15 seconds of timeouts, and so on. When getting error 42, it ALWAYS gets it for 18 seconds straight. It usually gets error 56 for 15 seconds (3 timeouts) but sometimes for 20 seconds (4 timeouts).
When the cRIO disconnects, it can't be contacted by any computer through the ethernet port, yet the link lights still show that it is connected. If its connected directly, both the green and orange link lights on the cRIO light up, but when it is connected through the 10 Mb hub, only the orange link light lights up, but the hub shows that the cRIO is connected to it. In spite of this, it is still impossible to ping the cRIO in either scenario.
It is possible that, in addition to what computer the cRIO is connected to, the errors could be related to whether the cRIO has a direct connection to a computer or if it is connected through a hub. Today, we have only managed to get errors when the cRIO is directly connected to a laptop (one error after 1.5 minutes, one after 10 minutes, one after 7 minutes, etc.) There were no disconnects when the cRIO was connected to a 10 Mbps hub for more than half an hour.
Do any of those symptoms give you clues about what is happening?
Thanks!

Disconnection from cellular network

since i've bought my new 3gs this week it keeps disconnecting from the network if i keep it without usage for about some time ..approx 30 min or more....when some one calls me he finds me out of service and when i call some one the call fails and i have to restart the phone to once again get connected to the operator and can make and receive calls normally
i tried everything reset network settings, reset all setting, choose carrier manually, i restored the whole OS from i tunes (3.1.3) but nothing worked the same problem occurs..note that am using it on 2g and closing 3g as i have weak 3g in my area...
am really tired from that issue..please any help that would be great!!

Where does Sting to IP get the net address if the computer is disconnected from the net? It should return the same I

P/Net address� it did not change. Internet Protocal(TCP/IP) Properties did not change. When the network is physically disconnected, my VI after several runs returns 127.0.0.1. So, how do I get my IP address whether it�s connected to the network or not?Thanks in advance for your help.

P/Net address� it did not change. Internet Protocal(TCP/IP) Properties did not change. When the network is physically disconnected, my VI after several runs returns 127.0.0.1. So, how do I get my IP address whether it�s connected to the network or not?If you're getting a dynamically assigned IP address from the network, then String to IP will return that IP but it may not be constant. See if TCP/IP properties are set to "Obtain an IP address automatically". If you disconnect from the network, then the IP address will default to something and I wouldn't be surprised if the default is 127.0.0.1. If you want to always have the same IP, then the ICP/IP properties should be changed to use a fixed IP but you'll certainly need to check with your IS department before doing so.

MBP Airport consistently disconnecting from the Web, but not the network

My MacBook Pro Airport has been cutting in and out - or at least the Web access has - when I use it in combination with a DLink router. The local wireless network connection always seems to stay connected (or at least it says it's connected), but I can't access the Web. It has shown these symptoms when used in combination with other routers too, but only when I use it with the DLink first and then move to another network.
I can sometimes fix the problem by a combination of restarting OS X and resetting the PRAM, and restarting the router. However, this doesn't always fix the problem, and even if it did, I'd probably be doing it at least once a day with the current frequency of disconnections. So I'd like to get to the route of the problem.
An ethernet connection to the DLink router always works without a hitch.
Does anyone have any suggestions or any knowledge that might help resolve this?

Just remembered I have the 'self assigned IP' error too. There seems to be a fair few posts about this issue. I haven't found a definitive fix yet, but these posts might hold some clues;

The second post suggests applying the 'Disconnect from wireless network when logging out', which I've applied, because I've noticed that I often see the problem when I put my MBP to sleep.
p.s. Last year I quick-fixed this issue by attaching a Buffalo wireless router to the network as an extension and connecting to that instead of the Dlink. But I just gave the Buffalo to someone, having forgotten about the issues with connecting to the DLink.

Does the iOS device connect to other networks? If yes that tends to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router

Connect to a network printer for air print, after disconnect from the wifi iphone keep pop up a message saying the printer is offline. How do I disable this annoying message?

Hey ronniefai,
Thanks for the question. I understand you are receiving a prompt that your printer is offline. This may be due to a printing job that is currently in the queue. Are you able to see the print summary when following these steps?:
Viewing the Print Summary
You can view the Print Summary by double-tapping the Home button and swiping to the right to reveal Printer Center. Then tap Print Center.
Note: Print Center is available only while printing is in progress.

If so, see if you can cancel the job. If not, what happens when you re-connect to the network that the printer is on?
Thanks,
