Mobile Broadband Router MNX5465R

Is the Novatel Merlin 720 pcmcia card compatible with the above router?

Apparently the above # is a catalog # for the WRT54G3G. So, is the Merlin 720 PCMCIA card compatible withe WRT 54G3G? Sorry about that.

    Hello,
    Did you find a solution because I am having the same issue with my Sony Vaio SA. It has a Gobi 2000 and works perfectly on Ubuntu 14.04 and all other distributions I have tried so i know the hardware is fine.
    I dont get the message repeating although I can get it like that by using the firmware from the AUR. If I use the firmware I got from my previous Windows installation then the error only occurs when turning the device on. This is so annoying
    I get the following:

  • Mobile broadband

    Hi everyone,
    I bought an iBook G4 (with Airport Card) about 10 months ago. I have dial-up internet with Optus but want to move up to broadband. Specifically "mobile broadband". I want to be able to connect to the internet where ever I am, even on the move (in a train or taxi). Can anyone recommend a mobile broadband server or even tell me if this is possible on the iBook G4. Thank you.

    I think you'll find that 'Mobile Broadband' (GPRS in the uk. I think it's the same in the USA) costs a fortune. It's somewhere in the region of 8GBP per MB. I'd suggest that you get broadband access at home and buy a Wireless Router with a DSL modem in it such as the 'Netgear RangeMax WPN824 MIMO-G Wireless Router' You could also get your Cell phone to work with your iBook over bluetooth or a cable connection to use if you require it but i'd desuade you from using it as your sole connection to the internet.

  • Mobile Broadband and Apple TV

    Hello
    I am looking at purchasing Apple TV but wondered if it would work with Mobile Broadband?
    Just wanted to find this out before I make the purchase.
    Any help would be appreciated.

    Depends what you mean.
    Any internet connection should work - wired or wireless.
    However, AppleTv will not accept standard USB Mobile Broadband dongles.
    If you had a computer nearby you could potentially share it's mobile broadband internet connection over ethernet or wi-fi to AppleTV.
    If you had some form of mi-fi device with a small wireless/wired router running from a 3G SIM you'd probably be ok, but mobile broadband might be too slow for good performance and unless you had extremely cheap data plans could be very costly.
    For example HD movies may be several GB in size, so you'd need to factor the mobile bb cost into the rental price.
    If your mobile bb device gave say a sustained 1-2 Mbps, then it might take several hours to download enough of a film to start watching without interruption - it would work but you might be better off letting it all download overnight for example before watching the next evening.
    It really depends on exactly what you're considering.
    Also, beware of quoted mobile bb speeds which are theoretical and rarely achieved in practice.

    Can you connect a mobile broadband device to a time capsule?

    Only if it has ethernet.. and offers the ip direct to the device ie you need a 3G router not a USB stick..

  • Huawei E173 mobile broadband modem install - lost access to Internet

    A few days ago I purchased the Huawei E173 mobile broadband USB modem ("Internet Stick") with SIMcard from Tchibo; they use the 3G+ network (HSPA/UMTS) from O2 in Germany.  I installed the modem with its "Mobile Partner" GUI in WinXP/SP3 on my Asus EeePC 1001R netbook and in WinXP/SP3 on a Dell Inspiron 6400 laptop and also installed the modem in Arch on the Dell laptop. 
    For the Arch install I followed the section "Easy Install using Network Manager" in the Archwiki "Huawei E220"; that was all that was needed, using NetworkManager, modemmanager and the Gnome network-manager-applet (nm-applet).
    All went well: I successively and successfully used the modem and got on the net in WinXP on the netbook, then on WinXP on the laptop and finally in Arch on the laptop.  Then I tried to use it again in WinXP on the Asus netbook: no access to the Internet.  Tried it again in Arch: no access.  Tried it again in WinXP on the Dell: no access.
    The symptoms were the same in all three cases: when the stick was inserted, the OS recognized it, it asked for and accepted the SIMcard PIN#,  established a link with the ISP access point - with excellent signal strength -, I was given an IP address in the 10.xx.xx.xx range, and according to the stick's LED, the connection alternated between being on an UMTS and HSPA net.  But no Internet access, neither in Firefox nor Chromium nor Opera, with and without firewalls or system proxies!  I was able to ping my own IP address but not the IP addresses of the standard gateway, DHCP server, and DNS servers, and some of these addresses were peculiar (I can provide more info on that).  And no luck pinging Google or Amazon, either with their hostnames or IP addresses.
    A support call to Tchibo confirmed that there was no O2 net service outage in my area, that signal coverage ought to be excellent in my area, incl. for an HSPA connection, that my new account was active and in good order, there was no block on it and there was plenty of high-speed data capacity left in it.
    So I exchanged the stick.  So far I've installed the new stick/SIMcard only in WinXP on the Asus netbook, with new cellphone # and PIN.  And everything is fine again; I'm back on the internet. 
    I don't want to be confined to browsing in Windows; Arch is where I do all my work and that's where I want to access the Internet as well.  But for nothing in the world do I want to go again through the ordeal of being completely locked out of the Internet and trying to troubleshoot this problem without access to it.  But I'm leery of using the new stick in Arch again and again experiencing the same lockout; I need to know what the cause of this problem was.
    I see several possibilities:
    1. Hardware failure of the first Huawei stick.
    2. Some network config setting might have gotten corrupted in going through two Windows and then the Linux install.
    3. Some account or network settings on the ISP side might have gotten corrupted.
    Re 1: Seems highly unlikely to me; the stick I returned worked flawlessly for 24 hrs. and is probably still perfectly all right.
    Re 2: Are such config settings stored on the SIM chip or elsewhere in the data storage section of the stick, so that they an incompatible setting might be carried over from one OS or install to another?
    Re 3:  Tchibo already seem to have gotten confused over the uses of the stick in my two Windows installs.  When I installed it in WinXP on the Dell (after having installed it in WinXP on the Asus netbook), the data volume counter was reset, and they again started counting KB's from zero in the Dell WinXP install, but kept track of usage from the Asus install separately, in spite of the fact that there was only one account with them, and account identifiers such as cellphone # and SIMcard PIN# were identical in the two cases.  Further, they don't officially support Linux; perhaps their software got totally confused by the usage coming from NetManager in Linux.  But one would think that this stick would be completely portable from machine to machine and from OS to OS, just like a USB WLAN adapter.
    Any thoughts about the cause of these problems, whether they might reoccur if I use the new stick in Arch, and how I can get around them?

    Thanks for the tip.  I'm very leery though of trying to use the new stick in Linux until I know exactly what caused the problem before because with the first stick it was after I'd used it in Linux (just once) that I lost internet connectivity in all three systems.  If that happens again, I'd be in the same hole as before: trying to troubleshoot a potentially complicated networking problem without access to the Internet.  Short of an expensive call to customer support of doubtful outcome that could cost me the price of the stick (not toll-free; costs 0.42 EUR/min), the only way out then may be to return the stick again and again set up a new account.  I doubt, they will go along with that.
    Setting up the stick in Arch was actually the easiest thing.  After I'd installed networkmanager, modemmanager, nm-applet and some other bits (such as mobile-broadband-provider-info), it was all plug-and-play, and with these bits of software Arch automatically set up a mobile broadband connection to the ISP's server and I had an excellent Internet connection.  Only after I went back into WinXP, did I lose all Internet connectivity in all three systems, even though I still got a good link to the AP (persistent misconfiguration of GW, route, subnet mask, etc?).

  • Mobile Broadband (3 Three UK ZTE MF622) and 10.5.3

    Hi,
    I have recently updated to 10.5.3 and now find that my 3 Mobile Broadband no longer works. All was fine under 10.5.2.
    I have deinstalled the drivers and reinstalled with no joy.
    I used the 3 supplied drivers from the USB modem itself (it mounts as a USB drive initially) which are revision B06 initally under 10.5.2 and these work fine creating 2 entries in Network Prefs Pane and installing an app (ZTE Mobile Connection). Launching this app and hitting connect on 10.5.2 produces a usuable broadband connection.
    However under 10.5.3 the 2 network entries do not get installed and although the application runs and connects, Safari (and any other internet using app) fails as there is no route out to the net presumably because of the lack of network entries.
    Needless to say I am getting nowhere with 3 customer services as although the modem supports Mac, sadly the helpdesk don't and can't assist me. They say its a Mac issue and I'm on my own.
    I can find no later drivers and can only put this down to 10.5.3. I have installed the drivers on a fresh 10.5.3 Mac (e.g one that hasn't had mobile broaband on it before) and get the same issues.
    I can find no reference to any issues for anyone else so I can only conclude its just me doing something wrong.
    Any help/experiences greatly appreciated particularly in maybe recreating the network entries from scratch if anyone is using the same/similar combination of hardware/software as me.
    Regards
    NIALL8-(

    Hi Niall,
    I am running ZTE MF622 and 10.5.3 successfully on my Macbook Air.
    Have you set up the network preferences pane using the ZTEUSBModem entry? Even though you should use the Three 'ZTE Mobile Connection' app to connect to the Three service, it seems the Network Preferences settings help. After setting a new location (perhaps 'Three') the network preference settings should be;
    Configuration: default
    Telephone Number: *99#
    Note that I occasionally get a hang up on closing the ZTE Mobile Connection app. This resolves with a force quit - and I'm guessing it may improve with future firmware updates.
    Regards

  • Can't connect to mobile broadband with NetworkManager and Huawei E1550

    Hi,
    I'm trying to connect to mobile broadband internet (3G) using my Huawei E1550 HSDPA USB Stick and NetworkManager but it won't work.
    At first, the LED on the usb device seems to indicate that the connection is established, but immediately afterwards it starts blinking again (which shows that no connection is established).
    nm-applet then tells me that I've been disconnected (although the connection was never established).
    I installed usb_modeswitch and modemmanager and enabled modemmanager with the systemctl command.

  • HP OfficeJet 8500 and Mobile Broadband

    Has anyone used OfficeJet Wireless 8500 and Mobile Broadband?  If so, what router did you use or would recommend.  Small Office, less than 15 feet in any direction.  Could not get a simple G router to work.  Thanks!

    Did a help desk ever ask you to check specific UDP or TCPIP ports in your firewall to ensure HP communication paths?
    They are not usually open in XPSP3 or W7SP1 even after you load the drivers or web mail.  In the updates they even state you must connect to update the device using USB even if you have LAN wired share with a static IP.
    I  have three W7 devices (OEM W7, refurbished W7 with updates from WXP (32 bit) and single license W7 on 64 bit hardware) and each of those have had rejections and failures on trying to load the print drivers and the solution center (version 14.0).

  • Can't send mail when using mobile broadband

    Hi
    I am getting quite frustrated as I can't send mail when using my mobile broadband modem! I can receive mail, and surf the internet etc, but mail just wont send!(i get the usual cannot send try later/resend options). I thought this might be an issue with my mobile broadband but have recently reinstalled it. When at home on a wireless network I have no such issues.
    Any help appreciated

    I am not using a SMTP it is a Pop3 domain name account from freeparking and uses mail.'NAME'.com for incoming and outgoing mail!
    Even though your e-mail service uses the same URL for POP3 and SMTP servers, in the software sense you actually do have separate POP3 and SMTP servers, although they may be hosted on the same machine, or the requests are routed via some "smoke and mirrors" to the right host.
    It is not related to my ISP at home, which is Virgin media. My mobile broadband provider is 3. I was thinking it might be that I need to change the port settings in mail when using my mobile modem, but don't know what to change them too(or how to do it!) or configure the modem differently but again not sure what to do there!
    Check with the freeparking online help to see if it supports port 587 or some such.
    Also try Mail's "Connection Doctor" (under the Window menu) when you're away from home to see if that shows anything useful.
    Since you can send e-mail from that SMTP server when you're at home but not when you're using your mobile broadband, I think one of two possibilities is likely: (a) Your mobile broadband provider is blocking your attempts to access the freeparking SMTP server and/or port. (b) The freeparking SMPT server for some reason doesn't like being communicated with via your mobile broadband provider. I'd check with each of them to explore these options.
    Does your mobile broadband provider have an SMTP server that you can use instead of the freeparking one?
    My modem(Huawei E220) is not particularly Mac friendly as it is, and I believe Mail can be quite sensitive when servers don't respond immediately?
    Yes. Mail seems to have a fixed time-out value for server responses.

  • Connect Mobile Broadband device to Airport Extreme?

    Hi,
    I'm thinking about changing broadband service providers.  I'm considering getting a mobile broadband device from either Virgin mobile or Netzero.  Both of these devices will allow me to connect up to 5 devices but when I start thinking about computers, phones, printers, iPad...we have more than 5 devices in the house that would want to connect to the wireless network.  I am corrently using an airport extreme (which I love).  Does anyone know if it's possible to connect one of these mobile broadband devices to the airport for a larger network?  If so, how?
    Thanks in advance,

    Hello,
    I guess that it would be correct to assume that you have looked at hotspot devices (small access points or routers with Wi-Fi capabilities). The following discussion concerned a similar problem, where Bob Timmons suggested to use Ethernet between routers. Unfortunately, a hotspot may not have an Ethernet (LAN) port at all.
    https://discussions.apple.com/thread/4033477
    One solution could possibly be a slightly different approach. There are several dedicated mobile broadband routers available (from Dovado, Netgear, Cradlepoint, and others). These typically accept a USB mobile broadband modem (check that the router has support for the exact model and the phone network in question). These routers do usually have at least one LAN port (which may allow a wired connection to another router, if merely the Wi-Fi capacity would not be adequate).

  • My Time Capsule and MIFI mobile broadband

    I just changed from broadband to MIFI mobile broadband and wonder how I can connect them so I can keep on my backup?
    Is that possible as I had it before connected with Ethernet to my modem....
    or is it useless now?
    Thanks guys!!!

    This is tricky alright.. the TC really doesn't like wireless connection.. but there is a hidden option.. hold the option key when you select the wireless.. instead of create or extend you will have a new option.. join a wireless network.
    Put in the SSID and security to your MiFi mobile device.. assuming you do have a router of some kind and not just a stick. This will make all backups very slow as it is double hop wireless. All packets must be double sent.. client .. mifi.. TC and double received.. TC.. mifi..client.
    When you put TC in this mode.. there is no ethernet or wireless from it.
    An alternative is to use the TC by ethernet direct to the computer and off the network. Mostly people with laptops find that harder because it takes the TC to be manually plugged in to work.
    You can also use a USB drive direct which is cheaper and easier. Much faster than double hop wireless too.

  • USB Mobile Broadband

    Hi,
    I've looked everywhere in the user discussions and can't find an answer to my problem. This is my first post, and I'm not very techie, so please go easy on me!
    I just bought my macbook pro, and I connect to the internet via 3's USB Mobile Broadband Huaweii E122. I have had no issues installing the USB software, and it connects to the internet fine on startup. However when I close the computer lid (and the macbook sleeps), then I reopen the lid, it doesn't let me connect to the internet. It detects the driver, sim card etc, but it doesn't let me press the 'Connect' button (the button greys out). I have to physically disconnect the USB and plug it back in, then the macbook detects the driver and sim card and I can press the 'connect' button.
    I have uninstalled and reinstalled the usb modem. Problem persists. I have tried using it in different usb ports on the computer, with and without a usb extension cable. I have called tech support at my internet provider, who have told me that I'm just going to have to live with unplugging and plugging back in my modem because that's how macs work (total waste of a 20 minute phone call!). The funny thing is, that when I first installed the modem it was fine - this problem did not exist.
    Every time I startup the computer it detects the usb and lets me connect absolutely fine. It only happens when I close the lid and reopen it again. Sorry if this is so wordy, and I hope it makes sense! It's not the end of the world but it is certainly annoying having to unplug and plug in this modem. Can anyone help me?
    Thanks,
    Brit

    No, no router. It's called Mobile Broadband. I plug the usb stick (I've also seen it called a dongle) into my computer and the internet travels with me. I looked online for details about the internet type and connection and the only information I'm given that it's high speed broadband. When it's plugged into the computer for the first time it installs itself, and there shouldn't be a need to remove it. It worked perfectly with my other laptop (this was windows based) and it works fine with my mac, except for the 'connect' button greying itself out when the computer awakens from sleep mode.

  • Mobile broadband software appears to have messed up my airport

    Can anyone help me fix this problem.
    The connection is great, I get a really great signal here so otherwise I am very happy with it, the trouble is though I would actually like the option to use a spuer fast wifi hotspot as well sometimes!
    So there I was yesterday at my local hotspot, switched on my mac- no signal. Why no signal??? NO AIRPORT!
    The software it installed asked for my system password and has taken upon itself to delete my airport and probably all the settings that went with it!
    Played around with it for a while. reinstalled Airport as Airport 2 then 3 and so on, and each time the software deleted it. So I installed it and locked the system preferences so no further changes could take place, and that worked in so far as it picked up the router, only every attempt to connect to the router ended in failure. Tried also locking the software but I can't even do that.
    I am really angry about this as I just spent some time re-installing the OS from scratch and sorting everything out, only to have their third party software take over my settings and screw everything up!
    As it stands now it sort of seems to work, but I am not near any hotspots to test it out. I can get as far as to the point where it asks for the password to my neighbours broadband. Maybe it works now, I don't know...

    Welcome to Apple's discussion groups.
    This may not help, but I'd use the Network panel of System Preferences to create a new "Location" and add an AirPort connection item to that. (To create a new location, pull down the "Location" list and select "Edit Locations".) In the new location add an AirPort connection item and nothing else.) If that works, you would use location switching to alternate between mobile broadband an Wi-Fi connections. The easiest way to do that would be to use the "Location" item under the Apple menu.
    For future reference, this discussion group section is intended for discussions of Apple's AirPort Extreme 802.11n base station. A better place for your post would probably have been in the "Getting Online and Networking" section of the "Mac OS X v10.5 Leopard" area.

  • Verizon 4G LTE Broadband Router - Does Verizon Issue You With A Public IP Address?

    Hi,
    http://www.verizonwireless.com/home-office-solutions/4g-lte-broadband-router-with-voice/
    Regarding the above Verizon 4G LTE Broadband Router, does Verizon issue you with a public IP address that can be accessed from outside of their network or do they issue you with a private IP addresss just like they do with their JetPacks?
    Thank you!

        That's an excellent question olimits7! It will be my pleasure to assist with your inquiry. Our voice and data services are transmitted using a 10-digit mobile number on our network.
