Ubuntu Networking :: PPTP Works Over Wifi But Not USB Modem
Feb 19, 2010
I am running 64-bit 9.10 on a Acer Aspire 1810T. I can connect to the internet via both wifi and the Novatel U998 modem. I have a PPTP VPN that works correctly via wifi, but does not work via the modem. The obvious problem would be that the ISP is doing something... but I'm dual booting Windows 7, and the ISP's Windows based software is able to connect to the VPN without issue.
I'm running VMWare player to be able to access my required Windows apps, so I'm almost in a position to dump MS if I can get this VPN issue resolved.

I am trying to connect to a PPTP VPN at work, and I cannot accomplish that. Both server and client are using Ubuntu 10.10.
Code:

I have a usb modem which I plug into my ubuntu 10.10 system for a dial-up service. The modem is recognised by wvdial and dials properly, but the connection is not established.I get "Unable to run /usr/sbin/pppd" (although pppd is certainly in /usr/sbin), followed by "Check permissions of specify a 'PPPD Path' option in wvdial.conf", and finally "Connected, but carrier lost", then it gives up.

i have a VPN server PPTPD on Centos 5.3
eth0: 62.2.2.x (public on the internet)
GW: 62.2.2.1 (cisco router)
i want to configure my ppptp server to allow users access internet with their own public ips of class 62.2.3.0 62.2.4.0 62.2.5.0
every time i configure my server all users can get thier IPs but they only go out with my server IP same as NAT not routing.
can you show me the proper configuration to make my users connect with public IP and have internet access. use specific DNS ( i did this but some users can not brows by DNS)
is there any way to specify an expired date for each pptp user.

I'm trying to connect to a Microsoft ISA PPTP server from my Linux box. The box I'm connecting from is itself a router. I have no problem connecting a Windows XP machine to the VPN via this machine. This is fine, but I would rather connect via the Linux machine, giving me far more advanced routing options (i.e. no to send every packet from the XP box completely unnecessarily via the PPTP tunnel). The Linux router is running Debian Lenny.
I've checked iptables. There were initially some issues. I've fixed those.
Invoking pppd from the console, I can see that authentication succeeds, but then some negotiation goes wrong and the server terminates the connection. Here's the output from pppd, with the more sensitive stuff removed:
Code:
<hostname>:~# pppd call <peer> nodetach debug
using channel 19
Using interface ppp0
Connect: ppp0 <--> /dev/pts/2
sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0xe3e45f75> <pcomp> <accomp>]

I just bought a TRENDNET TDM C4000 (=modem/ wiredrouter) and got it working. If I connect my computer with through the ethernet port directly, the internet will work. However, when I try connecting the ends of the ethernet cable on the modem and my wireless router, it's not transmitting. I know I set up the wireless router correctly because it worked with my previous modem. I just need to know how to configure my modem so that it works with my wireless router (D-Link DI-524).
I have a long wired ethernet wire to satisfy my academic needs for the internet at the moment but my mother is not able to surf the internet and it would be more convenient for myself to put the wire back to my desktop and have my laptop browsing wirelessly.

I tried ubuntu and am very happy with the smooth running and clean interface. I am having trouble setting up my network connections. It seems that I am unable to connect to the internet via my broadband modem if I am connected to my LAN via wifi. I think I need to seperate the networks so that the internet traffic does look on the lan for [URL]. I don't think I have had this problem when I used much smaller distros where I had to set it up by hand.
I might need to add some details I am just not sure what is relevant. I only have a basic understanding of what is going on.
solution:
Solved in #ubuntu irc chan with help by erUSUL.
Just in case anyone else is searching for the same thing.
In network connections in the ipv4 settings tab I edited routes by clicking the button and checked the box next to: "use this connection only for resources on its network"

When in XUBUNTU i click the picture of the 2 pcs indicating a network and choose "connect to hidden wireless network", put in the information.All this works nicely. When i reboot it's saved my config so i choose it to connect again but the "connect" button is disabled so i have to config it all over again and then it works. How do i get it to just connect to the network on login?

After upgrading to Ubuntu 10.10, I've had difficulties with my wireless connection. It will work for a few hours just fine, then suddenly disconnect and try to ask for my password several times before giving up. It's not the network--another computer on a different OS is having no such problems. Also, my wired ethernet connection works with absolutely no problem.

Im using Ubuntu netbook remix on my wife's hp mini. Ever since I switched my router out this netbook will connect to my wireless network, then show a disconnected icon, yet the internet still seems to work. I've searched around and seen that other people have had this issue but I haven't seen anything on how to resolve it.

just joined the forum so I am a little lost. I am trying to get my wifi to work on an HP Pavilion tx 1115nr (tx1000 series). I am using Ubuntu 10.04 desktop, my network card is BCM4311 rev1.I have read many threads and tried about everything, but I am so close. I can load bcmwl-kernel-source from the software center, restart and my wifi works for that startup. If I restart my computer again, it no longer works. I can then remove bcmwl-kernel-source and reinstall it and it works just once again.I have blacklisted b43 and ssblsmod reveals that these modules are missing after restart when wifi doesn't work:
arc4
lib80211
lib80211_crypt_tkip

if there is a simple wifi scanner for Linux. I need only basic information such as access points in the neighbourhood, signal strength and their broadcasting channels. I want to know the broadcasting channels in order to set my modem in such a way to avoid interference.

Wifi Works, but No internet When I'm directly connected to the Wifi router, via LAN cable, I have internet (this is how I'm posting now) I have a desktop computer, this is also the same problem. Because of this it hasn't updated to 10.04 yet. Its still at the version previous (9.??). Might be relevant. This problem began when my wife's Mac had an update that killed her Wifi access, and we had to reset the Wifi Router. She didn't change anything, we just re-inputed all the data as before (passwords, ID). Since then I can't access my internet even if I can connect to the wifi.
Other Observations In the office, my Laptop's ubuntu side has no problems with accessing Internet through the wifi. My Windows side is unaffected (both Desktop and Laptop). One time I can connect, but when that happened on that same day she can't. Possibly a fluke or coincidence. I read the post of a similar matter, where the person's Empathy still works. when I tried check if that was the case with me, after getting my Empathy to work it began to work again. But this hasn't worked in a succeeding attempt. Below is my system information if it may be relevant.

HPG62-144DX notebook, Windows 7 and considering Ubuntu. I installed 10.10 and tried to get my wifi running but that wouldn't work. I had a connection only sometimes and it broke up after 5 minutes. Once I got a webpage but annoyingly slooow. Got the advice to update drivers and stuff. But the wifi connection is the only one I have...
Went back to 10.4 32-bit. Booted from CD and will keep it that way until this is sorted out. Now I see my wifi hotspots directly and I have no problem to establish a connection. The icon shows 3 bars quality. Network Tools says: Wlan1 = Realtek, Transmitted bytes xxx Received bytes yyy, no errors, link speed = 1Mbps, State = active. Looks good!
The only minor thing here is that enabling/disabling my internal Atheros antanna also enables/disables my Alfa USB Wifi adapter (based on Realtek 8187) but who cares. A bigger problem is: when I start Firefox it doesn't come up with a webpage. It just keeps on saying: "loading". At the bottom of the screen it keeps saying "Looking up" for ages. Nothing further.

I have installed and setup 3G which works perfectly fine. I use sakis3g scripts for connecting to 3G network. My VPN profile created with network manager (client/NetworkManager GUI) works well.
#cnetworkmanager --activate-connection=user,'XXXXX_vpn_singapore',wlan0,&
Now when I do the same with using using ppp0 (which is after connecting to VPN) I get the following error messages. #cnetworkmanager --activate-connection=user,'XXXXX_vpn_singapore',ppp0,&

I switched from windows to Ubuntu 10.10. But I'm not getting along with it as well as I expected I would Specially cause I'm not getting the best out of it due to limited web connectivity. I used to use a usb WiMax modem back in windows (which is also supposed to be supported by linux as my service provider said) for internet. But I'm having a hard time configuring it on my Ubuntu. The modem works fine but I'm failing to install the drivers [url]. I used my cell as a temporary modem to get help from the web.
I downloaded:-
i2400m firmware 1.5.0
WiMAX Tools 1.4.5
WiMAX Network Service 1.5.2
According to the documentation, I'm supposed to install the linux kernel 2.6.35 which Maverick comes with anyway.
Then comes the part to install the firmware. The command I used was
Code:
But unfortunately and annoyingly the result is
Code:
I didn't get it. Am I missing any package or something?

I have installed and un-installed 3 different versions of Ubuntu. My fourth is a re-install of v9.10. During all these installs I have had difficulty getting my wifi to work. During my last install I left the ISO in the drive by mistake so when the system rebooted it loaded from the disc in demo.... This was interesting because in the demo the program manager showed 2 drives for wireless, 1 Broadcom STA and 2 Broadcom b43xx. I tried loading the STA and it worked! (sorry it could have been the b43xx, for the time being it's insignificant) Upon my excitement I restarted the computer and removed the disk went to my Ubuntu set up and ...what the Broadcom choices weren't there Why?
Now I am running Win 7 Home 32bit on my main drive and have Ubuntu loaded on its own drive. I have a Netgear WN311b wireless N card installed. Again my confusion is why it worked in demo (off the cd) but doesn't from full install. I read on the web to try inserting my supplied disc from Netgear and then search program manager. It now showed the two for-mentioned Broadcom programs, but this time wouldn't install them. On the b43 I got an error message and on the STA it searched extracting and loading this continued for a 1/2 hour with no progression. I couldn't close the PM or the extracting and loading box, so I had to restart the computer.

I recently bought a new wireless router (Cisco E1000) to use in my house. The E1000 supports mixed-mode 802.11n/g/b, which is what I have enabled. It is the first 802.11n router I've had. My netbook (an HP/Compaq Mini 110) only supports b/g. When connected to this new router, I can only see my status as root. NetworkManager shows a little red exclamation point, and 'iwconfig' shows nothing. It's missing in the 'iwlist scanning' list. Even still, I'm connected and can do everything just fine. However, everything shows up fine when I run 'sudo iwconfig' or 'sudo iwlist scanning'. These have always worked as a standard user before.

Today I got my laptop back after its motherboard was replaced (soundcard failure) and I am having problems connecting to the internet. Connection to the wifi network is succesful, but Pidgin is not connecting ("SSL Connection Failed") and I can't view any webpages in Firefox. I loaded up Win7 and everything worked fine, connecting to the same wifi network and using the same proxy settings ("No Proxy").

I was uninstalling some programs through the package manager, then restarted. When my netbook turned back on, I had no internet connection and the WiFi icon wasn't showing in the notification area as it usually does either. Says the card is functioning properly and everything. Other devices can connect to the WiFi.I'm kind of new to Ubuntu and searched around a bit, but am at a loss. HP Mini 110Ubuntu 10.10Broadcom BCM4313Edit: Quote:$ sudo ifconfig -s

I have an Asus EEEpc 1000H netbook with both Ubuntu and WinXp. I just updated from Ubuntu 9.1 to 10.04 and I can no longer connect to my home WiFi!
I have a Netgear router and the network is WPA-PSK password protected. All other devices can perfectly connect. The netbook can under WinXp and could with Ubuntu 9.1. Now, with the 10.04, it keeps asking for the password but never connects. Obviously I triple checked the password and there's no chance of a mistype error.

I have a USB WiFi adapter that my Ubuntu desktop install (10.10) automatically detects, and it works great. I just used the alternate installer to set up an old box as a server, and it doesn't install the driver for the adapter. lsusb finds the adapter, but I don't get a wlan* listed in /dev/. how I can determine what module(s) are used to run this adapter on the desktop so I can load them on the older box? Or is there some package I should install from the CD to help auto-detect the adapter?

find and install modem driver for the Alcatel X200 USB modem?
I've been all over the internet trying to locate Linux drivers but no success. Alcatel's website says is not supported, only in Windows. I'm sure there's gotta be a way to use the X200 in Linux.
