[usb_modeswitch] Problem connecting my Huawei E173

Hello Everyone,
I bought an Huawei E173 3G usb pen to use with my netbook when I'm not at home but I've found some problems with the connection of this one with Arch Linux.
The only way for the E173 to work properly is to put it in the computer and then boot Arch Linux (if I suspend, or even remove the 3g pen it becames nearly impossiblie to connect again).
Some useful information :
lsusb (when working) --> Bus 001 Device 009: ID 12d1:1c05 Huawei Technologies Co., Ltd.
lsusb (when not working) --> Bus 001 Device 009: ID 12d1:1c0b Huawei Technologies Co., Ltd.
I've found this line on the /lib/udev/rules.d/40-usb_modeswitch.rules :
# Huawei E173
ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1557", RUN+="usb_modeswitch '%b/%k'"
# Huawei E173s
ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1c0b", RUN+="usb_modeswitch '%b/%k'"
When the E173 is connected the Vendor ID is 12d1 and the Product ID 1c0b, and the E173 isn't found by Network Manager, then the Product ID changes to 1c05, only after that Network Manager detectes the USB and I can connect.
The problem is that, after disconnecting or suspending (or even when I connect on my USB3.0 port on my netbook), the Product ID stay's at 1c0b and I can't connect at all... not even "sudo usb_modeswitch -v 12d1 -p 1c0b -R" helps.
Sometimes when I connect the E173 and the switch is done, my screen turns black with text on it showing a sort of "kernel panic".. I just have to touch one key and I can use normaly my system... this is what it shows :

My early 2009 iMAC was connected to a 1 TB Time Capsule via ethernet cable. To improve my internet speed that cable now connects the iMAC to my cable modem.
The network speed through the TC should be just as fast as direct to the cable modem.. if it is poor then the TC is likely damaged or faulty.. Please tell me exactly the model number.
A1xxx from the base.. eg A1355 is gen3.
See Looking for Model # on Time Capsule
The early TC are known to go faulty which will make them useless for your purposes as well.
I've tried to connect the Time Capsule to the iMAC via USB cable
No, this is not possible.. the TC is a network drive now and forevermore.
and wifi (via a new NetGear router) without success.
Wifi might work but the setup is going to be messy. You will need to deliberately control the IP setup.
See this post. Using Time Capsule hardwired to Mac for back-up only.
BUT it is a poor setup still .. the TC is not going to give you either speed or reliability when using wireless.
In fact on a 2009 iMac the best solution for backup is a USB or FW800 drive. USB 2 is very far from fast but it is still faster than TC even over ethernet.. and on a 2009 model the FW800 is the best interface you have.. although it is a dead duck now.

  • 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?).

  • Unable to use huawei e173 with new iMac

    I've just bought the new iMac and attempted to use my t-mobile huawei e173 dongle to connect to mobile broadband.  The iMac won't even recognise it's existence.  I've checked the system and found the USB ports, but nothing is connected.
    It works on my Macbook Pro (2009 model, 10.8.2), so I wonder if it's the USB 3.0 port that is causing an issue - any idea how to rectify this?

  • I'm trying to set up my Ipod, but when I go to sign in with an apple ID it says 'Could not sign in: there was a problem connecting to the server'.

    I just bought a 3rd generation ipod touch. It was professionally refurbished. I'm trying to set it up, and everything seems to be working fine, until we get to the wifi. I live on campus and our wifi is username and password protected. I signed in and everything seemed to work fine, and in the top left hand corner I have all the bars for wifi. However, when I go to sign in with an apple ID it says 'Could no sign in: there was a problem connecting to the server'. I've tried turning it on and off again, tried signing on to our wifi again, but it all isn't working. What can I do?

    I also encountered the same problem. Try using a different email address or try signing in later.

  • Problems connecting multiple macs to an Airport Extreme network.

    I think this problem is similar to a previous post, but is individual in some ways.
    I have 2 Airport Extreme basestations covering a large flat connected by Ethernet extending a single network. I did try to extend the network wirelessly, but this was plagued with problems where the network would work for 10 mins, then drop out as I think the basestations are slightly too far apart.
    Connected to the network are a number of machines:
    Wirelessly we have 3x iPhones, 1x G4 Cube, 1x iMac (current model), 2x MacBook Pro (previous model) & 1x PC.
    Wired via a hub is an Apple TV, PS3, Nintendo Wii, Denon Home Cinema Amp, PS2
    For aprox 6 months I have had major problems connecting all the wireless machines at the same time. I have played around with the security as per previous posts with varying degrees of success.
    I seem to have the most problems with the iMac. The iMac will not join the network when there is any form of wireless security. Every time I try to set up a password it hangs when trying to join and I finally get the "There was a error joining xxxx network".
    After more playing around I managed to get all the machines working by having no security on the network and locking the network down by MAC addresses.
    Since last Thursday I now have a new problem. The iMac joins and stays on the network perfectly, but the second my second MacBook Pro is switched on and joins the network, the internet connection on the iMac drops out. In addition, as we use the iMac as a media server, all other machines connected to the iMac for either file sharing or iTunes sharing then get the error "the remote machine is failing to respond. Please check firewall settings if there are any". What is strange is that the iMac remains on the network, full signal, independent IP address and the second the MacBook Pro is switched off, works perfectly again.
    I have tried wiping both the iMac & the MacBook Pro and re-installing their operating systems, but this only solves the problem for aprox 24 hours then all of a sudden the issue re-appears.
    Can anyone out there help?

    Let's double-check the AirPort Express Base Station's (AX) settings ...
    Perform a "factory default" reset of the AX
    o (ref: http://docs.info.apple.com/article.html?artnum=108044)
    Either connect to the AX's wireless network or connect directly, using an Ethernet cable, to the Ethernet port of the AX, and then using the AirPort Utility in "Manual Setup" mode, check the following settings:
    AirPort > Base Station
    o Base Station Name: <rename or leave default>
    o Base Station Password: <enter desired password>
    o Verify Password: <re-enter desired password>
    o Remember this password in my keychain: (optional)
    o Set time automatically: (unchecked)
    AirPort > Wireless
    o Wireless Mode: Join a wireless network
    o Network Name: <existing AEBSn's wireless network>
    o Wireless Security: <select the encryption type of the existing wireless network>
    o Wireless Password: <enter the existing wireless network password>
    o Verify Password: <re-enter the existing wireless network password>
    Music
    o Enable AirTunes (checked)
    o iTunes Speaker Name: <enter desired speaker name>
    o iTunes Speaker Password: (optional)
    o Verify Password: (optional)
    o Click Update to write the new settings to the AX
    In iTunes:
    iTunes > Preferences... > Advanced > General
    o Look for remote speakers connected with AirTunes (checked)

  • TS3048 My early 2009 Mac Pro does not connect via bluetooth to my sound bar or bluetooth mini speakers. Both my wireless keyboard and mouse have no problems connecting. What do I need to do to connect to external bluetooth devices?

    My early 2009 Mac Pro does not connect via bluetooth to my sound bar or bluetooth mini speakers. Both my wireless keyboard and mouse have no problems connecting. What do I need to do to connect to external bluetooth devices?

    I would always have a wired keyboard and mouse on hand (need not be expensive ... any cheap wired devices will work).  "Emergency recovery" procedures can activate features in random order, so the opportunity to select a recovery partition may pass before the wireless devices are recognized.
    That will let you select the "turn on Bluetooth" icon.

  • Problem connecting MacBook to a Sharp video projector

    One of the great things I like about Macs is the easy way they (usually) connect to a video projector. Unlike a lot of my friends who run PCs with Windows I never had any problems whatsoever connecting my MacBook to a projector at the university and start my presentations.
    Until today that is.
    I tried to connect my MacBook with Apple's mini-DVI to VGA adapter to a Sharp ("Notevision") video projector and although the MacBook had the projector (even with its correct name "PG-M20X" and available resolution settings) listed under "Displays" immediately, I couldn't get the projector to show any more than "no signal" whatever input source I chose...
    What did I do wrong? Or is it the projector that is somehow "incompatible"?! Please help!

    MacBook   Mac OS X (10.4.9)   Core Duo 2GHz, July 2006

    Maybe this could help as well:
    After we tried several things with the MacBook (reboot, "detect displays" etc.), we successfully connected a Powerbook (15", FireWire 800, late 2003) to the projector, using Apple's DVI-VGA Adapter.
    So that did work out fine, but the MacBook didn't work on the projector. The cable that came with the projector was a VGA--DVI-A cable: there were only a few pins on the DVI-end of it going into the DVI-Connector on the projector. Could it have something to do with that? But why didn't the Powerbook have any problems connecting to the projector then?

  • Having problems connecting a late 2011 Macbook Pro 2.2ghz i7 to a Sony KDL-32L5000 using a display miniport to DVI adapter (DVI to VGA cord). The TV is not detecting the macbook. Anyone have this problem?

    You really have to mess with the resoluton, espescially the refresh rate, as it varies from projector to projector, monitor to monitor. Even within the same brand! Because so many manufacturers are trying so many different things to become the next cool kid on the block, and the way the formats are being configured that's now part of the game.
    That's why so many professionally produced corporate shows hire a dedicated projectionist for the video presentations. Too many bugs in the honey.
    Refresh & sesolution are the first things to look at.
    Just so you know that colors in PowerPoint PC, and PowerPoint Mac, don't exactly match... go figure.
    I forgot to mention another thing, sometimes it's the projector that needs to be tweaked.

  • Problem connecting my macbook pro to a wired internet connection via ethernet cable adapter

    I am having a problem connecting my macbook to a wired internet connection in an area in my workplace where there is no wifi.  The macbook works fine on the same internet connection via wifi in other parts but when I add it as a wired connection it doesn't show any connection.  I have turned off wifi to make sure that it is not trying to pick up a poor connection but I still can't get this to work.  I think I am trying to set up the connection properly but can't be completely sure.  Any help would be appreciated.

    Open System Preferences>Network and make sure Ethernet is selected. If it is, open Advanced Settings (at the bottom of the Network window). Click on the TCP/IP tab. Configure IPv4 should be set to "Using  DHCP".
    Configure IPv6 should be set to "Automatically". When those are set click the "Renew DHCP Lease" button

    Having problems connecting iMac(late 2006) running 10.7.5 to a Samsung Flat Screen TV using separate audio/speaker cable and HDMI standard cable, mini-DVI to HDMI video converter.  TV displays generic Apple galaxy background and "some" windows (e.g. screen resolution choices).   It does not show Mail or Safari menus.  System preferences'  display "gathered" the Samsung and chose its resolution.  I did not find a way to select the Samsung as my display.
    In addition to having old hardware, we have Verizon FIOS providing internet and TV access.  Is there any way to make this work for us?  We would like to stream video (Netflix) and view shows from the Web.  Do we need Apple TV to do this?  Or is it not possible with our old iMac?  My husband thinks that our Airport could be a factor. 
    Thank you

    Lately, I have been seeing a lot of posts with users trying to use their Macs/iMacs to mirror their streaming video from their Macs to an HDTV.
    There are, actually, many alternatives to choose from than just from a Mac.
    You need to have or invest in a WiFi capable router for all of these examples.
    Apple TV only integrates with WiFi and newer Mac hardware. So, if you want to have total integrated experience, if you have a 2011 Mac or newer, you might as well pay the $100 for the AppleTV box.
    If you have a older Mac, like I have noticed many users do, then you have other options.
    If you want to elimate long cable clutter and having your Mac at the mercy of your TV all of the time,  you can still use the AppleTV box independently or purchase cheaper alternative media streaming boxes from Roku, Sony, Boxee or any number of electronics manufacturers that now have media streaming boxes and media streaming capability built into DVD/Blu-ray players.
    These eliminate long cable clutter by being close to the HDTV where shorter, less expensive cables can be used.
    Another alternative for iPad users is to use an iPad with the USB/HDMI video adapter and use your iPad as the streaming box. This ties up your iPad in much the same way as it does with your Mac, but again the iPad can be close to the TV and use minimal cables to the TV.
    Another alternative to is to use a combination of an iPad and your Mac to stream content that is only available to stream online from a computer. In this case, you can use a desktop remote app on your iPad and Mac. A good and cheap Desktop Remote app is Splashtop Remote. This allows you to completely connect your iPad remotely, over Wifi, to your iMac desktop. The app streams both video and sound to the iPad which is still connected to your HDTV. The resultant stream video picture will be smaller than the size of your HDTV, but it will still be plenty large enough to watch. Again, if you own a iPad and an Intel Mac, this method also allows minimal cabling to the TV.

  • There was a problem connecting to the server ... OS 10.8.4 + WD NAS

    Dear all,
    first my configuration:
    iMac from mid 2012, MacOS X Mountain Lion, 10.8.4, iPhoto 09 v. 8.1.2 - all software updates done and up-to-date
    MacBook Pro late 2011, MacOS X Mountain Lion, 10.8.4
    NAS WD My Book World Edition II (white light), 2 x 1TB (configured RAID : 1TB mirrored), original firmware (01.02.14 with MioNet built on Thu Feb 9 14:11:48 CST 2012 ) NFS, AFP enabled
    a win 7 laptop and plenty of other devices
    everything on a LAN with GB router + WiFi
    I have my iPhoto library on my iMac, but the photos (the originals) stored on the NAS. I have the option "copy photos to library when importing" disabled. So I guess iPhoto has a reference / link in the library to the original files.
    Everything used to work fine until some weeks ago. Not sure what happened but suddenly I got the error message "There was a problem connecting to the server ... Check the server name or IP address, and then try again. ..." when I tried to import photos stored on my WD NAS.  When I want to display any photo stored on the NAS - same thing.
    Now I guess I have a bunch of gray hairs more while trying to get this fixed.
    I tried so many of the tips posted everywhere including booting in save mode, deleting the .plist files (first I actually tried to clean them using Xcode first before deleting them), etc. I cleared out KeyChain. I removed all recent entries (folders) and recent servers from the "history". I tried to connect as guest or named user. There are also no "logIn items" pointing to the NAS. I even tried to disable / enable AFP + NFS on the NAS, not to mention countless restarts of all the machines
    One other thing I noticed: Before that problem occured I was able to select the NAS in Finder and it would show me all the shares. When I selected one of them it was mounted automatically. When I select it now I get "connecting" for a loooong time and then "Connection Failed". Most of the time (not always!) however I am able to get in via "Go -> Connect To Server - smb://<nas server name>). And suddently after that also selecting the NAS in Finder shows me all the shares! Hoever even this not in 100% of all cases. I can replicate this from the iMac and the MacBook.
    I do use an external HD for TimeMachine to back up my data (directly connected via USB). No issues there.
    Not I really don't know what to do any more
    Do you have any ideas? Did anyone ever get a response from Apple with a useful solution that really hit the core of the issue?
    Thank you!

    SOLVED!! and I want to share the solution which worked for me with everybody here. Ultimately I had to install nettalk 2.2 on my NAS as described here: http://mybookworld.wikidot.com/netatalk2-2-on-whitelight . A nice description on how to do that can be found here: http://forums.macrumors.com/showthread.php?t=1102423 .
    One last remark: When asked about the "DHX2 login process", I opted to install the original version, so I can confirm this one works too.

  • "There was a problem connecting to the server" in iTunes after migrating to new mac

    I have a problem that is driving me crazy with my brand new iMac. I see many other people posting similar issues, but none of the other solutions seem to work for me.
    I had a MacPro and bought a new iMac, on which I used Migration Assistant to set up. So the new iMac is virtually the same as my old machine in terms of appearance and installed applications. Both machines have Mountain Lion 10.8.2. All software on both machines has been through Software Update and is fully up to date, as are the connected devices (iPhone and iPad).
    The problem is with iTunes. Every time I start iTunes (I think at the moment it checks my two connected devices) I get a pop up dialogue saying:
    There was a problem connecting to the server "MacPro".
    The server may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again.
    This dialogue continues to pop up constantly as long as iTunes is open, interrupting my work and frustrating me no end. The old machine is of course turned off and indeed is not available -- but I can't find what on the new iMac is so desperate to connect to it.
    So far I have tried completing erasing my iTunes library, deleting all the preferences, reinstalling iTunes from a fresh download of the dmg, safe rebooting several times with no peripherals connected at all, and deleteing other preferences like the Login Items, iPhone config and iPhoto. I have also cleared Recent Items from the apple menu and opened "Connect to Server" in the finder and cleared all servers from the dropdown menu.
    Last night I also completely restored my iPhone from scratch to see if that would clear away the issue and I have connected both iPhone and iPad to go through any apps that have permission to write content to my computer and deleted all of them completely from the devices.
    Nothing has changed at all after all that, and I have run out of ideas. Clearly there is something somewhere that has my old machine's name hard coded in it but I can't see any way to search for it. I would grep my Library folder but I think a lot of the files are binary so I'm not sure that would unearth anything. I've seen many posts saying that Apple phone support (which I would qualify for) can't help with this issue and so I have put off phoning them to simply run through all the things I've already tried.
    Any advice that anyone could offer would be extremely helpful. I can't use iTunes at all like this as it disrupts everything I try to do on the new machine.
    many thanks!!

    Nothing at all? Can't anyone help with this issue at all? I would be grateful for any suggstions as it is driving me crazy. It happens every time I open iTunes and also every time I open Mail.

  • I am having problems connecting to my home wifi with my iphone4s

    Over the past couple of weeks I have experienced a problem connecting to my home wifi service (Sky) with my iphone4s although my laptop connects fine. My phone also picks up the wifi at my place of work. At home when in close proximity to the router (netgear) on the phone the network name appears in the wifi settings but on the wifi networks page it does not get a tick against the name (wheel just keeps revolving). I have taken it back to the retailer (Vodaphone) and they recommend it be sent back to Apple (Liverpool or Manchester) as they consider it a hardware fault. I will be without the phone for probably 1-2 weeks and I use it within my working environment regularly.
    Has any one any ideas?
    jd
    ps. If I go down the route of 'forget this Network' will I need to do any resets on the router as I cant find the username and password when I enter my IP address for the router.
