UML295 and Lenovo X1 connectivity issues

I have a UML295 and I'm attempting to use it with Lenovo's X1 Carbon (Model 20A) and I'm having some serious issues.  Well, my end user is.  After a restart, card is inserted and works perfectly.  I don't need to open up the MBB software, anything.  If I disconnect or just remove the device and wait a few minutes to plug it back in, it doesn't' work.  Indicator light turns green, flickers, etc.  No internet.  I open up the MBB software and shows I'm connected but doesn't go anywhere, or the software doesn't recognize that the card has been inserted.  It displays this behavior on multiple X1 Carbon machines that I have here.  I've tested it on an older T530 Thinkpad and it works as intended.  No need to install the MBB software neither.  As soon as the indicator light turns green, I'm good to go on internet access.
Is there a firmware update or a known issue between these cards and the X1 Carbon?  It's frustrating to our reporters that they can't use their new laptops out in the field.
Thank you

USB modem devices need both drivers and connection software to facilitate a connection to the VZW network.  I suggest going out and downloading the latest of both from VZW and retesting on your machine.

Otherwise the problem that you mentioned here is specifically resolved by use of a Jetpack.  No drivers, no software.  All users need is normal WiFi and they will be able to access the internet just like at any other hotspot.  This was a big advantage for us in addition to the reduced hardware costs of broken USB ports on laptops and USB modems.

  • Issue with hostname "localhost" and general CR connectivity issue

    Hello,
    we installed SAP BOE with the integrated Tomcat 6. We used a Web Tier installation on the same host, but in different paths.
    Tomcat was installed under /usr/sap/tomcat/sap_bobj/tomcat and the SAP BOE package under
    /usr/sap/XXX/sap-bobj/enterprise_xi40. The host has two IP addresses, a physical address (A) and a logic address (B).
    We want to get a setup that uses the logical address whenever possible.
    We have issues with Crystal Reports for Enterprise XI4.0.
    When CR ist started from the BI launch pad, then CR ist started and tries to connect to "localhost". The hostname "localhost" is communicated from BI launch pad to CR.
    For sure, no communication with "localhost" is possible.
    When CR is started manually and a connection to the respective Tomcat server is initiated (port 8080, servername B, context /dswsbobje) we get the
    error message. please wait, no connection possible at the moment. I already read and applied SAP KB articles 1598906 and 1601997, but the issue is not solved.
    1- Where I can make changes so that BI launch pad will communicate hostname B and not "localhost" to start CR?
    2- Is there any local log file on the PC to check why CR can not connect, when started manually?
    Best regards Bernd

    we have installed BO 4.0 and Its working perfectly. we have using webi reports,

    It seems your LAP AP is not getting the iP of the management subnet and LAP is in different subnet than your management IP.
    Please try keeping the static IP on the LAP and then try joining it to the controller first and later on keep it on the DHCP.
    when AP is plugged into a switch, the switch port needs to be access with the right VLAN allowed

  • Apple TV and Drop Outs, Connection Issues

    I use AppleTV to mirror my ipad 2. it's great. Love it Then I'll try it again and it may work but often the icon disappears. I then clear the password then re-enter it and that will bring it back or if that doesn't work I may have to shut down my ipad 2 at least once.
    This happens almost every second or third time I try to use it.
    I currently have an iphone 4s, ipad2, ipod touch and as someone has said before, this is the first time I've been deeply disappointed in an Apple product. I expect glitches every now and then but this continual drop out and connection issues I have is beyond the joke.
    Does anyone have any solutions. Yes I have done all the updates, yes I am on the same network, yes airplay is turned on, yes home sharing is enabled.
    As you can see I am peeved!

    I too am having the same problem. I have a MB Pro running OS X 10.9.4 cannot see AirPlay option. Any solutions out there? Tried AirParrot but it is spotty at best.

  • TS1398 Ever since I upgraded to iOS 7.0.4 my wifi strength is very weak and I have connection issues all of the time.

    I upgraded my iPad 3 to 7.0.4 and now I have wifi issues I never had before and apple customer support is no help. Does anybody know how to solve this issue?

    Some things to try first:
    1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    4. Go into your router security settings and change from WEP to WPA with AES.
    5.  Renew IP Address: (especially if you are droping internet connection)
        •    Launch Settings app
        •    Tap on Wi-Fi
        •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
        •    In the window that opens, tap on the Renew Lease button

    Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
    Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
    You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

  • Contribute 3 and Dreamweaver 8 Connection Issues

    Hello,
    I'm having issues finalizing my site definition at the
    "Contribute" stage in Dreamweaver.
    When I test the connection from Dreamweaver's "Remote Info"
    stage, Dreamweaver successfully connects to the main directory: "
    http://domain.edu" (domain.edu), where
    I upload files to the main site (not connected to Contribute), but
    I want to connect contribute to a mini site in a subdirectory of
    the main site - "
    http://domain.edu/folder/folder".
    I'm stuck at the point where I click "Administer Site in
    Contribute" in the "Site Definition" dialog box. This is the first
    time I've set up a site in Dreamweaver with Contribute
    compatibility and a remote connection, so I have not run into this
    before.
    Everything was going fine until the "Contribute" panel.
    The Site root URL in the dialog box originally pointed to the
    index file of the existing mini site sitting on the server: "
    http://domain.edu/folder/folder/index.htm".
    When I click the "Test" button, I keep getting the error
    message:
    "Dreamweaver could not connect to the remote server... Please
    fix the remote connection before continuing"
    So, I changed the Site root URL to point to the root folder
    of the mini site:"
    http://domain.edu/folder/folder/index.htm"
    Then I got this error message:
    "Dreamweaver could not find a page at the specified site root
    URL"
    I changed it back to the original URL and went back to the
    "Remote Info" dialog. I thought that maybe the problem was that I
    was supposed to change the host directory to "domain/folder/folder"
    (from "domain") to reflect the exact folder that the mini site was
    stored in, but when I did, I got an access denied error.
    I am at a complete loss, please help...
    I am using:
    Dreamweaver 8
    Contribute 3
    Windows XP
    Has anyone gotten an answer to this problem? I have seen many
    threads in both the Dreamweaver and Contribute forums, but nothing
    looked like a solution or explanation of why this occurs. Please
    Help. I would like to use this tool throughout our college
    campuses, but I am loosing faith in this product. I know that If
    I'm having trouble, novice users will completely reject this
    technology...
    -Ena

    OK, Now I'm REALLY confused
    I gave up on trying to connect Contribute to my website
    through Dreamweaver. I figured I'd go back to Contribute and see if
    I could get the connection directly from Contribute. Somehow, It
    worked. I think I went to Edit > My Connections > Create...
    > and entered my FTP information and it worked! I still cannot
    connect through DW however.
    So far, this has allowed me to continue with setting up this
    site with Contribute. I'm still really confused as to what the
    problem is with Dreamweaver and Contribute working together.
    I'm going to go back and make sure that I can repeat whatever
    I did to get it working. The only thing worse than not being able
    to get something to work is stumbling upon the solution and not
    knowing how you did it

  • Time Capsule and iPhone 3G Connection Issues

    Just rolled out a new Time Capsule (current gen). All but one device was able to connect perfectly including two Mac Minis, iPad and Lenovo laptop (work). However, the iPhone 3G is showing as connected with a checkmark in settings but no wifi icon (just 3G) and I can't connect to iTunes for remote, etc.
    So far, I've done the following:
    Reset Network Settings in the iPhone 3G. Rebooted Time Capsule.
    To note, we set this up to "replace a current network" since we needed the SSID to be the same.
    Solutions?

    How is the TC setup??
    If it is in bridge then it should have no impact on the connection at all.. so please tell us that..
    If it is in router mode and was working in router mode, I do not know why it will have stopped.

  • Centrino Advanced-N 6205 and Windows 8 Connectivity Issues

    Hi. I've been having issues with the latest Lenovo issued drivers for the WIFI card (Intel Advanced-N 6205) v15.05.7000.1763.
    I have recently installed a fresh install of Windows 8 Pro on my W530 (2438CTO) and have been experiencing slow connections to Wireless networks with the default driver that Win8 installed (14.2.1.3) and decided to install the latest ones on the driver matrix (v15.05.7000.1763) however it caused a BSOD (with a particularly unhelpful message dead5002 message code - means nothing to me). As this the only change I made for several weeks was the WIFI driver I have regressed back to the old version and have not experienced the BSOD again.
    Has anyone else got problems with this driver and has anyone got a solution to why I am having this long delay getting a wireless connection (regardless of the signal strength or network)?
    Thanks.

  • IPhone 6 and Bluetooth phone connectivity issues with my vehicle: this is how I fixed it.

    With so many threads on this topic, I wanted to detail the steps I took to fix my iPhone 6 Bluetooth issues regarding connectivity to my vehicle and handsfree calling.  My phone was pairing with my vehicle without a problem and syncing my contacts and call history but when I attempted to make a call (from either the phone or the vehicle screen) the audio went out and I could not hear the call either through the vehicle speakers or on the phone. The call was going through but I was unable to see it on my vehicle screen and/or hear it either the phone or the vehicle screen. 
    Based on my research and what I have learned so far, the people having problems are those who restored their new iPhone 6 from an iCloud backup from a previous phone, rather than setting up their iPhone 6 as a new phone.  I did an iCloud restore from my previous 5s running iOS 8.   
    First, I am a Verizon customer and I enabled Advanced Calling on my line.  After I requested that this feature be added to my line, under “Cellular” settings on my iPhone, I enabled LTE voice & data.
    Next steps:
    1) Unpair/remove iPhone from the vehicle;
    2) Forget/remove the vehicle from the phone Bluetooth settings;
    3) Soft reset the iPhone;
    4) Reset network settings on the iPhone; and
    5) Pair the phone to the vehicle again and attempt to make a call. 
    If that does not work…
    6) Perform a factory reset, erasing EVERYTHING from your phone and set it up as a new iPhone rather than restoring from a backup.  
    Resetting the network settings seems to be working for some people.  It did not work for me.  I tried it a few times with no result.  I did the dreaded factory reset, paired the phone with my vehicle and had all of my Bluetooth functionality back and was able to use the handsfree phone with zero issues.
    I was on the phone yesterday multiple times with Apple, Toyota Entune, Verizon and my Toyota dealer. Verizon blamed Toyota Entune, Toyota Entune blamed Verizon and my Toyota dealer blamed Apple.  Nobody had a clue how to fix this issue or what was causing it. I don’t know the exact reason why the previous iCloud backups are killing the Bluetooth connections, I just know what worked for me and I thought it was worth sharing. 
    Good luck.

    The new 8.0.2 update DID NOT FIX THIS ISSUE AT ALL. After you power off and on with the phone, same issue as the 8.0, all 3 of my cars lost Bluetooth connection and shows no signal at all.  Good job Apple, what a lousy update you guys did.

  • Have you been getting timeouts and other weird connection issues lately?

    Internet connection has become a bit wonky as of late, have you been experiencing some or all of the following symptons?
    1) Most internet speed test sites just stop before completing as if they have timed out (i.e. speedtest.net).
    2) Sites will start loading quickly but then sometimes randomly stop and have to be manually refreshed.
    3) Downloads will randomly stop downloading for some moments before resuming (particularly from Steam)
    4) Tracert to some websites that were causing issues show timeouts on peering with Alter.net servers.
    Looks like there are some issues between Verizon and Alter.net (formerly MCI, now Verizon owned) in NY.... Any word on when we can expect a resolution? This is quite frustrating as it affects a good amount of traffic.

    I'm a little further east than you out here on Long Island, Touyats, but I've seen none of the issues you or the Original Poster here are experiencing.
    Assuming you're having the problems on a device connected to your router by Ethernet cable (WiFi opens up an entire range of other possible problems) you might try getting your router assigned a new WAN IP address. 
    If you want to give that a try, see this post for the steps involved:

  • I bought the iPhone 6 yesterday and am having connectivity issues

    I bought the iPhone 6 yesterday and over the course of the last 26 hours, I've had issues with my phone connecting to data coverage. I can make phone calls and send texts but my most used apps (Gmail, Facebook, Twitter, even the App Store) won't load because they can't connect. Shutting down and restarting the phone has resolved the issue but I don't think that's a suitable resolution long-term. The phone does display that I have 3 bars (or dots in the case of the iPhone 6) and shows "LTE" but the phone doesn't actually connect. Any suggestions/help? Thanks.

        Krallas,
    That is very strange behavior for this new phone to have, but don't worry, ok? We'll help you get it fixed. Please go ahead and turn the phone all the way off. Then remove the SIM card for at least 30 seconds, replace it, and turn the phone back on. That may just do it for you!

  • Cisco VPN 3.6.3b and BEFW11S4 v2 connection issue

    I'm hoping someone can help with this problem.  I am able to connect to my employers VPN server, but cannot access any of the shared areas.  I've found some documentation that may point to an MTU issue, but adjusting the value on the laptop from 1400 down to 1250 to 1200 doesn't work.  I've tried forcing the value to 1250 using the Router Filter settings with no luck.  IPSEC pass through is enabled on the router as is MAC filtering.
    I've tested the VPN while on-campus and I have no problems.  I also have no problems accessing the internet through the Linksys router with VPN turned off.
    Any ideas?
    Configuration:
    DELL Precision M70 running  XP
    Time Warner RoadRunner
    Motorola Surfboard Cable Modem
    Linksys BEFW11S4 v2 (using wireless connection) FW 1.45.10
    Cisco VPN 3.6.3b

    Ok thanks so much. I will try again. 
    My company's IT guys aren't  being very helpful, won't return my calls, emails, etc. and don't appear to be giving me clear instructions on what I believe to be a standard request.  Not sure why .
    We can't get in as administrators, they have to do it for us, and they are not timely in requests like these.  We are a large company (over 10K employees) and the last time I tried this was with our email client and and Cisco VPN, bundled together. It was a disaster and I don't recommend it.  So this way was supposed to be easier for the user, and for them to help us with questions.  Oh well. 
    I will at least try what you have suggested, and when I get back to work I will see if I can get their public ip address, and see if they will check on the port.  
    I will post back to see if the suggestions from the above post worked.
    Many thanks again for your help!

  • WRT54GS and MS Outlook connectivity issue

    Hello All,
    i have just got the WRT54GS wireless router, i have configured it and it is working. however MS Outlook is not able to connect to exchange server (i am using MS Outlook in cached mode and connectivity over HTTP) when i connect directly to the modem it works fine with no problems at all.
    also not all the web pages are accessable through the router and not all the time.
    i understood that prot triggering should solve my issue along with setting manual MTU. anyone can please help and tell me what are the exact ports i need to trigger ? any idea on the correct MTU?
    thanks in advance for help.

    thanks for the advise, however this requires knowing the ports working on the exchaneg server, which i dont really know! as they have to be the same in order to allow for the connection.
    i was looking for the opposite to open the ports in the router.

  • WRT55AG and XBox 360 connectivity issues

    I've had this router for almost 2 years and in the last month I've started developing issues of when I play a game on the XBox 360 I get constant issues with lag and disconnecting errors that make playing any game online impossible, but I never lose connection to XBox Live. This is happening with multiple games including Team Fortress 2, Call of Duty 4, and Halo 3.
    Now before this I would have problems where the router would completely lose connection with my cable modem and I would have to reset everything but then it would be fine. Now I don't lose internet connection (PC is wired into router while 360 is wireless with Microsoft's official Wi-Fi periphial) or XBox Live connection, but any game I try to play is a fruitless endeavor because of lag.
    My ISP is Charter Communication in the St. Louis area, and my connection is 3 down, 256 up. I have done speed tests and I'm getting pretty much those speeds exactly. I have opened the ports to make my NAT open, and the XBox test confirms my NAT is open.
    I'm at the end of my rope, any help would be greatly appreciated.

    Open routers set up page using http://192.168.1.1 ...leave username blank & in  password use admin....
    Click on "application & gaming" tab ...... forward the ports 88 & 3074 for static Ip of X-BOX ....enable the servie & click save settings ....
    USe static Ip ...subnet mask ...gateway & DNS numbers on X-BOX confgiuration
    Do power cycle & see if you arew able to play games online or not...
