Ubuntu Networking :: Wireless Broadband Freezing ?
Apr 8, 2010
I have cricket wireless broadband and the starcom um100 usb stick. It reconized it when I first put it in and was able to set it up. I connect to the internet and I am able to go to one or two pages before it freezes on me.
I ran the lshw -C network code and this is what I got it doesnt see my wireless
When I connect my wireless it does see it when I ran the lsusb code ( it didn't see it before when I didn't have it connected)
Here are some screen shots of what I got when I ran these codes:

The first two times I entered the wireless key on the prompt that appeared shortly after login, the computer froze completely. ctr-alt-f1 ctr-alt-backspace did nothing. The third time, I closed the first prompt and after 10 minutes I tried connecting again. It didn't freeze, at first. The internet worked. It took about 10 minutes later for it to freeze. Now, whenever I boot up, it freezes a few seconds after login. I can boot recovery mode, but I don't know what to do from there. Heres some info I got from the recovery mode:
Computer Brand: Sony PCV RX850
Ubuntu 10.4 32 bit 2.6.32-21-generic i686
Realtec 8185L chipset
iwconfig

I first noticed the problem because my wireless internet will stop working. The usb stick has its LED constantly on but it fails to connect. I have tried some methods of restarting the networking, like "sudo restart network-manager", disabling and re-enabling the wireless and networking from the taskbar applet. I tried removing the module and restarting it. It might be a bigger problem because I'll find that things will randomly hand for awhile, like opening system monitor, or running terminal commands. They do eventually run but only after several minutes. A restart seems to get everything working again, but the problem comes back at random times. I am willing to solve this right now as I have time, just let me know what info you need and I will post it.
Update: Some more info I forgot to include. I am running Ubuntu 11.04. It just froze again, I tried logging in and out but the internet still wouldn't work and things were hanging, I couldn't get file manager open. I have even tried shutting down the computer and had it stall on the Ubuntu logo with the dots loading so I had to hard restart.....

Using my usb mobile broadband dongle I am able to access the internet about 25% of the time. I am able to make a connection to the '3' wireless network 100% of the time, but often Mozilla and all other applications that rely on an internet connection do not recognise that this connection has been successfully established, and give me error messages claiming there is no internet connection.
I can't discern any pattern as to whether the connection will be recognised or not. When it isn't recognised, the only solution is to disconnect and reconnect to the network. Sometimes this works and sometimes it doesn't. Sometimes restarting the computer fixes the problem, and sometimes it doesn't. I also have access to a wireless network at uni. I have no problems using this network whatsoever. Housemates using the same dongle on Windows have no problems. I'm using an Acer Aspire one, the dongle is a Huawei e220, I'm running Ubuntu 9.10. I have only recently reinstalled the operating system and have not needed to mess around with any network settings to get the usb dongle to 'work' the way it is currently.

I've just completed switching both my laptop and desktop from Ubuntu 10.04 to Kubuntu 10.04, all seems to be working well, except that I can't get my Virgin Mobile HUAWEI E160E wireless broadband modem working. I used to have it working flawlessly in Ubuntu, I've used the smae step as described in this post: [URL] that worked for me with Ubuntu, but the Wireless Broadband tab is greyed out under the manage connections dialog. I'm running the 64-bit version of Kubuntu BTW.

I am deployed to Iraq and the Earthlink ISP here uses PPPoE to configure a connection to their wireless broadband. His english skills are pretty good and from what I gather, he's got a DSL connection that he's trying to connect me to. He showed me how he does it on a Windows machine but I can't figure it out on my ubuntu laptop. That windows machine didn't need any IP addresses or server names. It only used a username and password to connect. Of course a strong wireless signal detected was also pre-requisite.
I know my laptop works because I've had great success with it here lately, just not on the Earthlink service.I see their wireless is broadcast and I can connect to it. I just can't figure out how to post my credentials and authenticate.I don't see a way of entering my username and password because I don't know how to install (or configure) for PPPoE.I did use the pppoeconfig and got to the part where I add my username and password, but most of what's going on up to and after that, I do not have the knowledge base to use. So I figured that allowing the defaults and recommended settings would be acceptableYou'll have to forgive me if I've asked another dumb question here. I'm another one of those Linux enthusiasts who is learning and I'm just not willing to switch back to MS just to get internet while deployed.

I've looked quite a bit, but didn't find an answer.
I have a Thinkpad x61s which comes with a "Sierra Wireless Mini Card module".
When I start up my computer, I get prompted for a PUK / PIN.
"Unlocking SIM PUK required" (sorry, this is a direct translation of the French, might not be the exact same words in English)
With three fields to fill:
Code PUK
New PIN Code
Reenter new PIN Code.
I don't have a card in my computer, and broadband mobile is not activated in networkmanager.
Does anyone have an idea how I can disable this prompt (I don't intend to put in a SIM card before some time).

I had previously been sharing my ethernet connection over wireless using Hostapd & dnsmasq on my headless server as this tutorial shows: here which had been working fine. I now wish to share my USB mobile broadband over the wireless. I using a ZTE MF112. I was able to get the connection working using the application wvdial.
- Firstly I had to create a hard link between /dev/gsmodem & /dev/modem
- wvdial then made a new connection ppp0 which would work for internet access.
Changing the interfaces to have the br0 port like so:
Code:
iface br0 inet static
address 192.168.1.1
network 192.168.1.0
netmask 255.255.255.0
broadcast 192.168.1.255
bridge-ports eth1 ppp0 wlan0
Flushing the IPTables & then adding:
Code:
iptables -A FORWARD -i br0 -s 192.168.1.0/255.255.255.0 -j ACCEPT
iptables -A FORWARD -i ppp0 -d 192.168.1.0/255.255.255.0 -j ACCEPT
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
Doing so works fine, but I'm not entirely sure how to make this all automated. I could try making a script to launch, but I don't have a huge amount of experience writing scripts. Is wvdial the best application to use? Keeping in mind I'm using a headless server. I use Squeezebox server & the scrobbling didn't seem to be able to connect to last.fm. Do I need to specify which connection Squeezebox uses?

I am trying to use my air card (Sprint U760), which works under Windows, on CentOS 5. I have a manual from Sprint that has instructions but I am having trouble with installing required PPP packages. The Sprint instructions say to go to Add/Remove Software and download packages KPPP and KPPPLogView. However, these packages do not appear in the list of available packages. I do have a working hard wired connection to the internet while I am get the air card working.

I just got a new Asus Eee 1001P, and the wireless isn't working at all. I had an Asus EEE 1005HA before that and since both use the AR8132 network card I hoped it would be the same problem as with that, where installing the backports fixed the problem. However, that doesn't do anything. With the 1005HA the connection was only flaky and disconnected a lot, but the 1001P doesn't find any networks to connect to at all. Also, the mobile wireless will connect only once and after disconnecting every attempt to reconnect ends in that connection symbol spinning wildly until I tell the network manager to disconnect. On Kubuntu it doesn't even connect once.I never had that problem with the 1005.
Code:
$ lspci
01:00.0 Ethernet controller: Attansic Technology Corp. Atheros AR8132 / L1c Gigabit Ethernet Adapter (rev c0)
02:00.0 Network controller: Atheros Communications Inc. Device 002c (rev 01)

I have a Acer Aspire running dual boot Ubuntu 9.10 and Vista. Although it has an Atheros wireless card (AR5001 according to linux, AR5007 according to Vista) until recently I didn't have any apparent problems with it.I installed a ZTE MF112 Mobile Broadband Dongle. Now I am experiencing great difficulty in communicating with my wireless router (with both LAN and WAN traffic). Connecting to the network in the first place appears to happen quite smoothly and my computer obtains a DHCP IP address. However the ping response times are measurable in seconds rather than the milliseconds I would expect, and any traffic across the network crawls, or just times out and fails.
I do not believe it is the router at fault as two laptops, both also with Ubuntu, can connect to it fine and swapping it out for another router does not fix the problem either. Also there is no problem connecting from Vista.I suspect that installing the dongle has altered something which has made the bugs in the wireless card/drivers apparent and that's where I need some help.

I have a Sprint U760 air card that apparently works under Linux. Sprint has a guide: "Wireless Mobile Broadband Setup Guide for Linux OS" that I am using to setup the air card. When I go through the procedure in the manual for "Setting Up PPP Using KPPP" the last task is to query the modem to see if Linux recognizes it. When I do the query I get a response "unable to open modem". I have tried going back through the PPP setup but still get the same response.

I have internet access using mobile broadband and i also have a wireless network for home usage without internet access.
When my wireless network is connected every application in ubuntu (Meerkat) tries to use it for inernet access (as neededobviously). As soon as i disconnect from the wireless network (and assuming the mobile broadband is on) everything has access to the internet again using the mobile brodband.
How do i tell ubuntu that i don't want it to use my wireless network for internet access?

It has been haunting me for weeks and I haven't been able to fix it so far: When I installed the wireless driver 43XX series on my laptop using a wired internet, I saw the wireless network for a while and after I rebooted my system, My kernel(31) got corrupted and I got error "kernel Panic (and some sync error)",Thus I started using an older kernel(14),Now When I install wireless driver or mobile broadband driver(wvdial), they get vanished after the reboot and my mobile device modem isn't detected.But they are installed in my system(as shown by synaptic package manager but doesn't seemt to work) I desperately want to use mobile broadband.

I had the Wireless Broadband working. It stopped working after I closed the laptop (suspend). Also the wifi will not connect until reboot. Now the entry for the Wireless Broadband is gone, and the tab for it is greyed out as well.I would be happy to submit this as a bug and assist with the debugging process.

I have Ubuntu 9.10 on an Asus EEE900 netbook, and I recently got a Telstra Broadband Wireless modem. I get on line fairly easily, generally the device comes up as a CD and I have to unmount it � I know there is a solution to that: [URL] The really annoying problem I have is that I get on line, there is a message to say I have Telstra NextG, Skype works, but Firefox and Evolution often don�t connect � this is a bit random. I can�t see what the problem is, they are not set to Work Offline. I get around the problem by rebooting, sometimes 2 or 3 times, until they do work. There must be a simpler solution here, what could be happening? I have mainly used this computer at home on a wifi connection, without this problem, I just turn it on and everything works.

Let me start by saying that with the previous kernel 2.6.31.5 when I opened network configuration, it didnt even recognize my card when i'd go to modules. After I updated to 2.6.31.8 it didnt recognize it until I installed the ralink-firmware 1.1.3.5. After that I could configure it using rt2870sta setting in modules. But once I restarted it would freeze after a few seconds after I could see the desktop on startup. I reconfigured the card to be 'manually' powered, but now it just freezes when I click on the access point I want to connect to. When it freezes the caps lock and scroll lock start blinking and the only way to turn off is holding the power

I have just recently installed Open SUSE 11.2 from a CD I got from a Linux Magazine.Installed this fine as a dual-boot machine on my HP laptop.To access the Internet, I have normally used 2 ways:1. WIFI Connection via my home desktopUsing Netgear WG111v3 USB Adapter.2. Virgin Broadband USB Mobile Broadband stickI have no problem connecting this via my Windows Vista operating system.Somehow, under Open SUSE 11.2, this is a problem. 2. Virgin Broadband - I managed to get the Virgin Broadband icon of a mobile phone saying that it's connected and "Active" by keying in the number "*99#", username/password as blank and APN as VirginBroadband". However, when I launch Firefox browser, I couldn't get to any external Website even though the icon for the Virgin Broadband says that it's Active and connected.
So what's the problem ?1. WIFI Connectivity to Home Desktop WIFI - with this I have never never got any connection at all. It kept saying "Activating" and I have set up the connection and entered the WEP 128-bit paraphrase hex digits. I managed to scan and got the correct SSID and as I know they belong to my desktopI read somewhere that Netgear WG111v3 is not compatible with Open Suse 11.2 and will need to install the driver for this. So I did obtain the .INF file and installed ndiswrapper -i with the .inf file.. However, still not successful.I'm thinking of buying a Belkin USB Adapter which is in the list of compatible USB WIFI Adapter for Open Suse 11.2 - .. the 802.11g chipset.. as I couldn't get this to work

I need help with connecting to cdma mobile broadband for a tethered samsung phone. When I first installed Suse the phone icon on the network manager icon was all i needed to do to connect to the cdma network.After rebooting later the icon is gone and i cannot manage to connect. The connection is still there, but it is as if the computer no longer recognizes my phone as a modem. Well sense i just installed i figured lets try reinstalling to see if it was a bad installation. It happened exactly the same again. If anyone has any idea how to get network manager to allow me to connect to the internet again i would be grateful.
specs:
toshiba satilleite l305
Suse 11.3
Samsung R560 (Samsung Cdma Technologies)

I have Slackware 13+current as of Jan 31, 2010. Except that kernel is 2.6.29.6_smp. I brought yesterday a new Globe Tattoo prepaid kit (a wireless broadband kit -- mobile broadband service here in the Philippines) which uses Huawei E1552 HSDPA USB stick (usb modem).
I understand that they don't natively support linux but from what I've learned, they are the most linux friendly wireless broadband provider. There are few success stories about installing them on Ubuntu, Xandros, Linux Mint and OpenSuSE.
I do searched the net and found: [url]
Which says I need to compile to create a huaweiAktBbo but when run, it says 'dev' failed. (Compile succeed though).
I tried kppp but my Huawei USB stick is detected as USB storage and not as a modem, so i need to use usb_modeswitch.
I grab it from [url] and tried to download the source but it seems that SlackBuilds has not updated yet its link (and the slackbuild package). I tried to make and make install the latest source from [url] but I think I forget that switch-data and conf, anyway I have to re-download again.
Do I need libusb? Or slackware 13 already have it? (I just learn while typing this that I forgot to download the switch-data and the conf file)
Another thing, I found this: [url]
But it says I need the qt compat lib from /extra? Is it this: [url] ?

I'm using a 'ice.net' D-50 (CDMA EV-DO rev A) mobile broadband USB modem, also sold as Cmotech CNU-680 in other areas. The modem is connected to a USB port on a hp8710w mobile workstation.
As the 11.2 Gnome Network Manager won't connect this modem to Internet (see my first post here), I have downloaded and installed a 'D50 Modem Manager program' from [url]
After unpacking and installing this cmotech-qtmodem-1.6-1.i586.rpm package for suse on 11.2 x86_64, the gui application 'D-50 Modem Manager' is found in the Internet Group.
However, neither this program does connect the D-50 modem really on 11.2 x86_64 (as it did on 11.1 x86_64). Tried both traditional network setup and with Network Manager.
Any idea and suggestion how to trobleshoot this further? I think I've seen that a newer version cmotech-qtmodem 1.9 has been mentioned on the web, but without being able to find and download this version.
Command output as follows:
As normal user:
On the Modem Manager gui: D-50 modem is ready
From Login script Debug window:
As root:
It seemed like the modem connected, but Firefox was not able to connect afterwards (Server not found)

I am trying to use the HUAWEI E1756C USB stick to connect to the internet. Installing usb_modeswitch and usb_modeswitch-data allowed networkmanager to "recognize" the stick and set up a mobile broadband connection.
The result is that NM succeeded in connecting (one of every five attempts) but firefox does not surf, nor emails can be downloaded etc. Just like if not being connected. The USB modem shows the steady blue LED as connected.
A NM issue? I have tried disabling NM control and tried with PPP clients like NMTSMON, wvdial and even Sakis3g. All with the same results. They seem to connect and show flux up and downloaded but no surfing.
resolf.conf shows is pretty much empty and no DNS there.
The working settings in Window$ are:
Same settings with Sakis3G, or NMTSMON or NM result in connection with no action from applications that use the internet.
I have had a similar issue with WLAN each time I change to a different network. I solve that by forcing to update the DHCP. I mean using -su dhcpd wlan0
But attempts like dhcpcd ttyUSB0 or dhcpcd ttyS0 get the same result. So no idea if this is an DHCP, or DNS or another issue.
My box is an ASUS EEEPC 2005H netbook with OpenSuSE 11.2 and KDE
