Some Basic MiFi 4510L Questions

I just received my MiFi 4510L and am already having issues. I have gotten it to work with my WiFi iPad, but not reliably. I am hoping some of the experts can answer these questions. I am in need of step-by-step instructions, if that is possible.
How can I see the log that I read about on this forum?
Why does MiFi change from 4G (green light) to 3G (pink light) when I have not physically moved? Speed correspondingly changes from 7mps to .5mps.
I have had some trouble turning on the MiFi - where after a full charge, it turns on and then immediately shuts down. I have also seen a red light on startup, indicating SIM card problem. Should I exchange device for new one?
Generally speaking how long will MiFi device run on battery? I imagine it depends on system activity, but could you provide a range of up time?
How long does it take to charge a fully depleted battery?
How can I tell what version of the operating system I have? If I do not have the latest (2.23?) how do I perform an OS update?
Many thanks for taking the time to answer.

Hello,
In response to your questions:
1) To view logs:
1. Connect to the Mifi
2. Navigate to http://mifi.admin
3. Sign into the MiFi
4. Navigate to Advanced > Diagnostics
5. Click the System Log button
- You may have to enable your logging feature the first time.  Steps should be displayed on the MiFi.
2) Your MiFi will automatically transition between 3G and 4G in your area depending on the quality of the signal.  This normally happens when the MiFi detects an issue with 4G when 3G is also available.  You can configure around this feature and lock the device in either 3G or 4G if you find it annoying.  I would also suggest updating the firmware to the latest as each firmware update so far has been released to address this issue.
3) Those are all good reasons to call in for a replacement device or parts.  You might want to examine the battery and try using the MiFi without it for a while to compare.  Remember that the device will not remain powered on with a USB connection unless you are on the most recent firmware version.  Red lights are also a good reason to call in for hardware replacement. 
4) Battery life is rated around 6 hours, but I find I can normally get around 4 with normal useage.
5) Fully charging the battery does not take too long.  I would estimate around 20-30 minutes.  I normally charge and use my MiFi at the same time though.  If you can give it enough juice to boot then you can attach the power cable later and continue to use it.
6) We refer to the OS as firmware.  Your Firmware version can be found under the Diagnostics screen from the steps above.  Look for the value next to "Modem FW Version".
Let us know if you have any other questions.

  • Some basic form submission questions

    Hello,
    1. On page 1, I've created a form which contains only one text field (P1_USERNAME) and a submit button which leads to Page 2. On page 2, I can't seem to access the value of :P1_USERNAME. From Page 2, when I press the 'Session' button, it shows P1_USERNAME with the correct value under Session State.
    What am I doing wrong?
    2. Page 2 is a User Profile page, which needs to display various information about a user whose username was entered on Page 1. Is it possible to run only one query and fill the disabled text fields on Page 2 from that one query instead of running a separate SELECT queries for each field?
    Thanks :)

    1) In what context can you not access the value of P1_USERNAME? Describe how you trying to access its value. If you see the item and its value in the session state, it is definitely accessible from page 2.
    2) To display the user's current profile just create a SQL report region with the SELECT statement's WHERE referring to P1_USERNAME. Something like:
      SELECT first_name, last_name, ...
        FROM user_profile
       WHERE username = :P1_USERNAMEMike

  • Some basic questions on File Adapter

    Hello all,
    I have some basic questions on XI and File Adapter and hope you can help me. Any answer is appreciated.
    1. Can I use NFS transport protocol to poll a file from a machine in the network, which is not the XI? Or do I have to use FTP instead?
    2. If I understand it correctly - when using the FTP-File Adapter, XI has the role of a ftp client. I have to run a ftp server on my distant machine. XI connects to FTP-Server and polls the file.
    Can it also be configured the other way round? The scenario I think of would be: FTP client installed on distant machine, which connects to FTP-Server(XI) and loads up a file. So XI would act as FTP Server.
    I know this works, if I install a ftp Server on the computer my XI runs on, and use the NFS-File Adapter to observe the folder. But I want to know, if I need a second, independant ftp server for this.
    3. And last but not least: When do I need the active ftp mode instead of passive?
    Thanx a lot for your answers!

  • Some basic question about SCM Installation

    Hi Folks,
    Could you please advice me about some basic questions about SCM and its installation -
    Q1. Do I need to have an R/3 System to be able to practice OR demo the SCM system?
    Q2. If, yes, which version of SCM is compatible with the ECC 5.0?
    Q3. What are the basic requirements to install SCM (version compatible with ECC 5.0) and ECC on a oracle db and windows OS?
    Q4. Does SCM have APO and BI as an inbuilt functionality OR does the user need to purchase these as an Add-On?
    I know these are some basic questions, but these will help me give me a direction.
    With best wishes,
    Krishna

    Hello Krishna -
    Q1. Do I need to have an R/3 System to be able to practice OR demo the SCM system?
    ---> There are various Modules in SCM Like APO (Sub Modules  DP (stand alone), SNP Needs Master data from R/3 and has to pass on transactional Data to R/3, PPDS same as SNP, GATP same as SNP), ICH needs Data from R/3 to work with. Core Interface (CIF) connects R/3 to APO for transferring data.
    Q2. If, yes, which version of SCM is compatible with the ECC 5.0?
    -->For thorough understanding explore the following links
    http://help.sap.com/saphelp_scm41/helpdata/en/9b/954d3baf755b67e10000000a114084/frameset.htm

    Q3. What are the basic requirements to install SCM (version compatible with ECC 5.0) and ECC on a oracle db and windows OS?
    -->Refer Above
    Q4. Does SCM have APO and BI as an inbuilt functionality OR does the user need to purchase these as an Add-On?
    --> APO comes with a small BI inbuilt functionality. you can only perform certain functions using that BI.
    Hope this helps.

  • Some basic questions on ESS and MSS

    Hi Experts,
    This is the first time I am going to deal with
    ESS and MSS.
    I have some basic questions about it and they are
    listed below:
    1. In an organization if they want to integrate
    ESS and MSS, how do they go about? What I mean
    is, will they install the packages in the R/3
    system and then use the to portal features to
    make iViews of ESS and MSS.
    2. Or is there a seperate package for the portal
    and the R/3 system
    3.What is the best way to customize ESS and MSS
    iViews? Is WebDynpro used to customize ESS and
    MSS applications, if yes how?
    4. Are these ESS and MSS packages different for
    ECC and the older version of R/3 systems? If yes what are the major differences?
    Please do let me know on these subjects and also
    if anyone of you have any links or documents
    associated with this scenario please do send me.
    Thank you
    Regards
    Luke

    Hi,
    here is what I know..
    1 & 2. Depending on the backend SAP version, the relevant ESS/MSS Business Packages have to be installed on the Portal. On the backend it will be via an Add-on.
    3. The webDynpro versions of ESS/MSS are available from mySAP ERP2004/2005 (ECC5/6). The best way to customize the iViews would be through the NetWeaver DevStudio.
    ent
    4. Yes, the ESS/MSS packages are differ depending on the backend SAP version.
    You can find all the  different packages & their info right here on SDN. From the home page click on the Portal Content Portfolio on the right hand side of the page>Browse Content Portfolio>Self Service for ESS & Line Manager for MSS.

  • Some basic questions on HANA

    Hi All,
    I have some basic questions on SAP HANA,
    I heard from one of my colligues that it is mandatory to learn SQL scripts for HANA, is it true?
    Or basic knowledge is enough for HANA???
    Is it added advantage while working on HANA or can we manage with basic knowledge of SQL???
    I tried to find answers for these questions in SCN, but I could not get proper answers, So could you please provide answers for above my questions.
    Thanks in advance,
    Venkat Kalla

    Hi Vladmir,
    SAP HANA is a platform and is more than just database. Which can serve both OLTP and OLAP.
    But since it is a database, Sp SQL skills helps you while modelling in SAP HANA. So When will it be helpful ? It is while addressing some complex requirements using SAP HANA.
    At the end of the day, when you want to work in HANA ( a super duper database ) and you still thinking of whether to learn SQL or not?

  • Need answers for some basic question

    The Informatica server software usually runs on some server machine.The client tools usually run on those Windows PC with which developers to their work. That's a pretty much standard client/server architecture.On Windows servers you will often (not always) find the client tools as well, but that's by no means mandatory.Communication between PowerCenter clients and PowerCenter server usually takes place via TCP/IP; the protocol, as far as I know, has been developed by Informatica in-house app. in 1993-1995. The installation of the server software usually is the task of some server administration team. You will also need some DBA team because the Informatica software (almost) always stores its controlling, scheduling, and runtime information in some relational database system. Importing of relational structures (meaning table and view structures) usually is done on a client PC which connects to the respective source and/or target DBMS via ODBC.The server uses either native database client installations (for Oracle, IBM DB2, Microsoft SQL Server, and Sybase) or ODBC to communicate with the source / target databases. Best thing is that you download the documentation and start browsing the Installation and Configuration Guide; this PDF file explains quite a few concepts fairly well. Regards,Nico

    Hi, 1) a server installation is a server installation and nothing else. It also contains some clients (namely the command-line client tools), but definitely not the GUI clients (this is an extra installation always to be done on a Windows PC as of this time).2) That depends on your business processes. Sometimes files will be placed in some directory (e.g. /opt/transfer/inp) and then the respective workflow shall start, so it might read this file directly. If some business user can only deliver via email, then you will need an extra process which extracts the file(s) from the email and places them somewhere where the server processes can access them.3) Unix is a computer operating system. Windows is a computer operating system. They are just in use in different cases (at least often). Some basic Unix knowledge (about the most common system tools and a bit of shell scripting) is definitely useful / necessary if you want to work with Unix systems.4) A data warehouse stores information which usually is needed for enterprise-wide strategic business decisions. A server is a machine offering software services. One kind of servers are database servers, and data warehouses usually (not always) are stored in a databases. So some sort of server is the technical basis for a data warehouse.5) Usually these two terms are identical in meaning.6) Unix is an operating system. A shell is a program which enables you to interact with a Unix system. Shell scripting means that you automate moderately complex or highly complex tasks using a programming language which is provided by the shell. Different shells offer different scripting facilities and features. Writing a shell script is a matter of programming. Your questions are by no means stupid. They just show that you still have a lot to learn, but that's ok, we all should try to learn more as long as we live. Regards,Nico

    Hi,
    I have problems to understand you question but will do a try:
    From a logical point of view objects can be only serialized reasonabely when they have a state of it's own which can be reestablished at a later point in time and space without further dependencies.
    F.E. a "serialized file" would NOT make much sense cause it depends heavily on the state of the underlying file system.
    You can't expected that is can be deserialized at a later point of time (physical file refered may not longer exists) or on another machine, where the serialized object was transported to.
    Technical - at zero approach - it's more or less trivial. Simply implement Serializable and all non static, non transient fields of your object will be serialized automatically.
    But there is a couple of pitfalls, you should study documentations regarding this feature.
    Hope this helps

  • Some basic questions about serialization

    Hi,
    I have some basic questions on serialization.
    1. What are the basic criteria to make an object serializable(except that it must implement serializable ?) I mean that objects of some class inherently cannot be serialized so any object must have some features which makes it serializable/non serializable.
    2. I know it makes no sense to serialize a socket because it is fixed only by specifying ip and port at both ends, and is valid only when the network connection remains valid. Still in the context of my previous question, I would like to know why a socket cannot be serialized.

  • Some Basic Questions in ODI

    Hi,
    I am a fresher in ODI That's why I have some basic query On ODI:-
    *1)What are the importances of Physical and Logical Architecture in ODI(In Topology).Mainly what are the basic differences of the contents of these architecture so that we need both of them??*
    *2)What are the importances of the Master and Work Repository???And some basic information about their contents??*

    *1)What are the importances of Physical and Logical Architecture in ODI(In Topology).Mainly what are the basic differences of the contents of these architecture so that we need both of them??*
    Physical Architecture holds the real information to your dataserver .
    For example ,if your server address has changed then you need to modify the Physical Architecture so that it reflects the current/corrent address
    Logical Architecture connects to your Physical Architecture via context . Entire ODI code works on Logical Architecture .
    For example ,if your server address has changed then you need to modify the Physical Architecture so that it reflects the current/corrent address and there is no need to change any thing in your ODI code.
    *2)What are the importances of the Master and Work Repository???And some basic information about their contents??*
    These are the most important thing in ODI. Entire ODI application depends on these.
    Master repository holds all metadata stuff like information about topology , technology
    Work repository holds all design related info like interface, package etc.
    Thanks,

  • Very slow connection with Mifi 4510L??

    I'm hoping someone here can give some guidance. I am having very slow connection with the 4510L we just got. Via test on speedtest.net I'm seeing download speed of .17 MBPS at times it was so slow the test was not completing. I normally have 1 or 2 bars on the mifi unit and have seen up to 3 at times. I drove into town and see the same range (1 to 3 bars). I have yet to see the 4G light come on except for prior to activation (would light solid green at times) since activating I have only seen the violet light for 3G.
    Verizon advertises full service both around our city (Richmond, VA) and at my more remote location in Hanover. I have been through the recommended resets and nothing seems to improve the connection speed. Could the unit itself be defective? Also, I've noticed when I go to a location website it thinks I am in Pennsylvania when I am in Virginia. Could the Mifi be trying to connect to a signal in that location for some reason (was refurbished device)
    Thanks for any help you can offer,
    Brian

    I was having problems but upgrading to 2.28 seems to have helped me in addition to a few other changes I made based on this review of the 4510L
    http://www.anandtech.com/show/4500/novatel-wireless-mifi-4510l-review-the-best-4g-lte-wifi-hotspot/4
    1) "selecting WPA2 Personal/PSK (AES)"
    2) "manually selecting a channel (instead of Auto) fixes almost all the instability problems"
    (I'm not sure if it actually worked as the diagnostics always shows channel 0 no matter what I picked.  I did try a couple before one - or the myriad of other things I tried - seemed to make a difference - at least for now - fingers crossed)
    3) "allowing for one to select between each network mode manually, so you can force 4G LTE, EVDO, 1xRTT, or all of the above. This is incredibly useful if you’re right at the cutoff for 4G LTE SINR"  (that's WWAN Preferred Mode LTE only for me)
    4) I also changed my 802.11 Mode to just one mode that works on both computers at my house
    5) I am also careful to turn it off when I am done with it and take it off the charger for the night as well.
    It is my only internet service due to my semiremote location (no cable etc) and when I first got it as a replacement for my dependable 2200 I was about to pull all my hair out.  I was "forced" into it because due to antenna issues on a local tower that supplies my 3G signal my 2200 wasn't even able to load my gmail account.  Verizon very helpful on that - call us if its still an issue in a "few weeks"!  However, when I inquired about the antenna's effect on a 4G signal, an intelligent tech was able to tell me that it was not the tower I would be getting a 4G signal off of - odd but I didn't question that possibility.
    It runs very very warm but I suspect having it on the charger and using it almost all day is part of that.  At first I was wondering if heat was part of the problem - going so far as to have it sitting on an ice pack to test that theory.  Of course then I had to wonder if maybe I was freezing it -lol.  I am careful to turn it off when I am done with it and take it off the charger for the night as well.
    I've been on it most of the day and it seems to be behaving well - so fingers crossed

  • Mifi 4510L and 4620LE throughput slows throughout day eventually locks up in 24-48 hours. New Update?

    Hello all. I have had a Mifi 4510L for about 6 months and its behaved pretty well. A lot of drop outs but it would reconnect and keep going. I bought a 4620LE last month and tried it for a couple of weeks. I noticed when I first powered it on it said it was installing an update. After the first day where it seemed to work fine, I rebooted it to leave on while I returned to my home.
    The mifi unit is on a farm about 100 miles outside of town and is my only link to my farm and observatory (via gotomypc). I can monitor the observatory, close the roof if weather turns bad and take images of objects in the sky. Well its obviously a very high priority that the connection be maintained unless I want a 200 mile round trip drive in the middle of the night.
    So the mifi 4620 was great on paper but but as the day went along it would get slower and slower. If I restarted it it was normally good for another 24 hours. However one nite it decided to stop working at 1:30 AM which caused a 3 hour drive to find it had just plain locked up. So I took it back and returned to using the 4510L with out difficulty again even though it was a bit choppier but comparatively very reliable.
    Then last week the same affliction began with the 4510L. Getting slower and slower throughout the day unless restarted. And today having forgotten to recycle it yesterday I'm getting ready for a 3 hour drive to go power cycle it.
    So I have a couple questions.
    1) Have there been any new updates that may have occurred lately and is there anyway to roll back the updates if this is true?
    2) I have a powerstrip ordered that can ping the mifi unit continously to see if its down and then powercycle the powerstrip its attached to. It can also do that every day at a certain time. I would have to take the battery out so when the power is cycled for 10 seconds it would shut off then back on.
    The main question on this is, is there a way to have the mifi unit power back on in an active mode instead needing the button depressed to bring it back to life?
    For information I'm about 5-7 miles from a tower and am using an external antenna with a 3 watt amplifier. It ha always preformed well, well until just before Xmas.
    Thank you all for any help to a tricky situation!!

    Hmm interesting on the power strip idea. I've written some software that can remotely manage my mifi (performing web requests to restart it). If I remove the battery from mine (only powered via usb or outlet) it just goes into an endless loop of powering on and then off again. How'd you get yours to stay powered on?
    My software doesn't work when the mifi has crashed though

  • Storage rules for an editing rig. Some basics.

    How do you set up your editing machine in terms of disks for maximum performance and reliability? (SSD's are left out here.)
    This is a question that often arises and all too often one sees that initial settings are really suboptimal. These rules are intended to help you decide how to setup your disks to get the best response times. Of course the only disks in an editing machine must be 7200 RPM types or faster. No GREEN disks at all.
    Rule 1: NEVER partition a disk. You may ask why? First of all, it does not increase disk space, it just allocates the space differently. However, the major drawback is that for a partitioned disk the OS must first access a partition table at the beginning of the disk for all accesses to the disk, thus requiring the heads to move to the beginning of the disk, then when it has gotten the partition info move to the designated area on the disk and perform the requested action. This means much more wear-and-tear on the mechanics of the disk, slower speeds and more overhead for the OS, all reducing efficiency.
    Rule 2: Avoid using USB drives, since they are the slowest on the market. Do not be tricked by the alleged bandwidth of USB 2.0 advertisements, because is just is not true and remember that the alleged bandwidth is shared by all USB devices, so if you have a USB mouse, keyboard, printer, card reader or whatever, they all share the bandwidth. Stick to SCSI or SATA disks or e-SATA. If needed, you can use Firewire-800 or even Firewire-400 disks, but they are really more suited for backups than for editing.
    Rule 3: Use at least 3 different physical disks on an editing machine, one for OS/programs, one for media and one for pagefile/scratch/renders. Even on a notebook with one internal drive it is easy to accomplish this by using a dual e-SATA to Express card connector. That gives you an additional two e-SATA connections for external disks.
    Rule 4: Spread disk access across as many disks as you have. If you have OS & programs on disk C:, set your pagefile on another disk. Also set your pagefile to a fixed size, preferably somewhere around 1.5 times your physical memory.
    Rule 5: Turn off index search and compression. Both will cause severe performance hits if you leave them on.
    Rule 6: If the fill rate on any of your SATA disks goes over 60-70% it is time to get a larger or an additional disk.
    Rule 7: Perform regular defrags on all of your disks. For instance, you can schedule this daily during your lunch break.
    Rule 8: Keep your disks cool by using adequate airflow by means of additional fans if needed. You can use SMART to monitor disk temperatures, which should be under 35 degrees C at all times and normally hover around 20-24 C, at least in a properly cooled system.
    Rule 9: If people want raid, the cheapest way is to use the on-board IHCR or Marvell chip, but it places a relatively high burden on the CPU. The best way is a hardware controller card, preferably based on the IOP348 chip. Areca ARC and ADAPTEC come to mind. 3Ware uses it's own chipset and though not bad, they are not in the same league as the other two. Promise and the like in the budget range are no good and a complete waste of money. Expect to spend around $ 800 plus for a good controller with 12 connectors internally and 4 e-SATA connectors. Important to consider in a purchasing decision is whether the on-board cache memory can be expanded from the regular 256/512 MB to 2 or even 4 GB. Be aware that 2 GB cache can be relatively cheap, but the 4 GB version extremely costly ($ 30 versus $ 300). For safety reasons it is advisable to include a battery backup module (BBM).
    Rule 10: If you can easily replace the data in case of disk failure (like rendered files), go ahead and use raid0, but if you want any protection against data loss, use raid 3/5/6/10/30/50. For further protection you can use hot spares, diminishing downtime and performance degradation.
    In general when you get a new disk, pay close attention to any rattling noise, do perform regular disk checks, and in case of doubt about reliability, exchange the disk under guarantee. Often a new disk will fail in the first three months. If they survive that period, most of the disks will survive for the next couple of years. If you use a lot of internal disks like I do (17), set staggered spin-up to around 1 second to lessen the burden on the PSU and improve stability.
    Hope this helps to answer some basic questions. If not, let me know. Further enhancements and suggestions are welcome.

    store material for a day work
    fast and reliable

    Installation RAID
    just to install Windows XP with CS4 Master Collection
    redundant but speed isn't critical here

    Working RAID
    for page-file/scratch/renders
    as fast as possible
    disc failure isn't a big problem

    In order to realize this, I am thinking of the following configuration
    RAID Type
    number of discs
    Type
    GB/disc
    tot. storage [GB]
    usable storage [GB]
    cost [€]
    Offline Storage
    8
    SATA
    1500
    6000
    4800
    900

    SCSI/SAS
    300

    2100
    Installation RAID

    Working RAID
    4
    SCSI/SAS
    147
    580
    470
    1000
    Here are my assumptions and constraints:
    I only have 6 bays for the Installation - and working RAID;
    For the video RAID I also would like to reuse an enclosure, which just has 6 bays;
    I would need to buy a NAS enclosure - so here I am open minded and just assumed 8 bays;
    the usable storrage I estimated as 80% of the total storage;
    discs, which are used heavily should be SCSI or SAS - I am thinking of the Cheetah 15K
    Looking into the cost associated, I hit 4000€ easily just for discs. Ok, I can reuse some discs and enclosures, which I have here - but since I need to purchase the NAS enclosure (with 8 bays), which will also cost 1000€ additional,  I will use 25% of my foreseen budget for storage.

  • Some very "newbie" networking questions -- trying to get started

    Hello all. Since this forum is so friendly for issues related to Arch, I thought I'd post my semi-arch related question.
    I'm trying to create a network for my house, consisting of about 3 computers. I have a book reference, TCP/IP Network Administration from O'reilly, but I think I need a bit of a "kick-start" in order to get to a level in which I can comfortably understand the book (if that makes sense).
    I've got internet access working by connecting to a router and having everything configured by DHCP (ie, in rc.conf, eth0="dhcp"). What's bothering me (and I don't even know if it should) is that the other computers on the physical network are not visible to me.
    IE, when I try to connect to them with their host name, it doesn't recognise them. My understanding of that is that either I need to manually set the hostnames of the other computers on the network in /etc/hosts, or use something like a DNS server on one of the computers in the network in order to recognize the others.
    My other doubt is that I think I've got a dynamic IP address (though it might be static, I'm not quite sure). Does that change things?
    I don't expect you guys to completely run through me setting up the network (that's what the book is for!) but some basic advice on either my misconceptions (I'm sure I have plenty) or related in general to my situation would be awsome and highly appreciated. I'd also be happy to provide any additional info that would be helpful.
    Thanks in advance.

    My set up is simple.
    I have a Linux router running on an old Pentium machine. It has two cards, one configured for the private network (with an address like 192.168.1.1) and the second card set up to take addresses from DHCP ( since that's how Rogers sends you the public address).
    In that machine I run my firewall, SmoothWall (smoothwall.org) and have enabled NAT so the machines in the inside network can go to the Internet.
    I have Samba set up in another machine to share files (that's an Arch system) with static IP, my daughter's machine (another Arch system), my system (obviously another Arch with static IP) and my wife's machine with Windows XP system (static IP too).
    So, the key concept here  are:
    1. Use static IPs for the private network
    2. Use DHCP for Rogers
    3. Use NAT in your router so all the machines can go to the Internet but no one from the Internet can get to them.
    Hope this helps.

    p.s. feel free to contact me off the list if you need further details/help.
    Aha! So, for example, the network 192.168.0.0 where mask is 255.255.255.0 is a private network set up by my router, right?
    So the addresses in 192.168.0.0 never change, but the public IP address of the hosts do change?
    Does that mean that if, for example, I have a host called 192.168.0.32 that its address never changes? Can I simply add that to all the other hosts' /etc/hosts file and it won't change?
    All I was ever concerned about was allowing hosts in the network to contact each other via hostname. If that never changes then I'm all set.
    BTW, thanks for your continuing help!

  • MiFi 4510L Problems - unable to browse web but can ping !

    Have had stationary 4510L for months since my local store rep convinced me to upgrade my perfectly good 2200. Wish I had never done so. First the 4G/3G connect issues kept me from working until the recent firmware patch was finally released. But mixed in with that issue is another one that has gotten progressively worse.  Three replacement devices and two new SIM cards later and I still have the issue.  After three (alleged) trips to the tower reporting no issue, I decided to take the MiFi on the road to see if I have same issues on another tower.  I do.  Anybody else seen these symptoms or have any suggestions?
    1) Browsing fine, usually in forced 3G (EVDO) mode due to earlier issue resolved by firmware upgrade.
    2) Suddenly web sites stop responding with timeouts, or server unavailable, or web site taking too long to respond messages (depending upon browser in use).
    3) WiFi connection is good and I can browse locally to access modem.
    4) Modem states to be connected and not dormant, with decent EVDO signal strength.
    5) Connection log shows some TCP and UDP traffic.
    But cannot browse anywhere.  The only fix is to disconnect and reconnect.  Then it all works fine.  The WiFi connection is never lost. Don't need to reset the modem, just drop the call and then reconnect.
    Logged 12 to 15 calls on this and have not gotten satisfactory response yet.  Spent hours and hours collecting data on dates, times, screenshots, etc.  Two very interesting things that I think would be indicative of issue:
    1) Even though I can't browse web sites, I can ping them !!
    It's as though internet layer protocols are working but transport layer are not.  When I can't browse, I also lose my VPN  connection (if a session was established). Cannot reconnect VPN, says the server does not respond, but I can ping it!
    And in the Connection Log, I can see the ICMP traffic from the ping, along with TCP and UDP.  Yet cannot browse to any website.
    2) Once this problem occurs, the clock starts to drift from real time.  The time stamps in the Connection Log and in the System Log are a few minutes off, then ten to fifteen minutes off, then withyin a few days they are an hour off.  They occasionally show 1980!!  A hard reset re-synchs the timestamps to the system clock.
    *ANYBODY* have these symptoms or any suggestions?  And if you have issue where browsing stops, but WiFi is still wokring, try pinging the website and see if you get a response.  I'd like to hear form you.

    I have the *exact* same problem.  Been happening for months and nobody at Verizon has a clue.  I am going insane!!!  My problem is especially worse when I have more than one WiFi client connected.  "Stop browsing" means unable to browse the internet.  I can still browse on the local MiFi private network fine.  Just can't browse thru the Verizon network!
    One laptop will stop browsing (but can still ping!!) while the others are working just fine.  Dropping the wireless and reconnecting doesn't fix it.  Rebooting the laptop doesn't fix it. 
    One client can browse but the other can't (but both can ping) and there is nooooo way to fix it but disconnect the call and then reconnect.  FRUS.STRAT.TING !!!!! 
    Happening now five or six times per day. We may have two to four laptops connected at any given time. Mostly we just do w/o internet on the clients when they stop browsing.  The other laptops will continue to browse for quite some time.  Eventually, when the working systems have an opportunity, we have to drop the MiFi call and reconnect to restore internet to everybody.
    THIS IS KILLING ME.
    I cancelled my voice service this week and transferred to ATT.  T-mobile has a $40/month 5GB plan that does not charge for overages.  I'm considering switching to that.  Verizon, how many customers will you lose before you get your act together?
    MiFi 4510L - replaced twice, latest one is three weeks old
    Modem Firmware - 2.16.07 (the latest),
    Using EvDO with better than -80 signal strength
