Ubuntu Networking :: No Internet Access Through Wireless Campus Network?
Feb 10, 2011
I am trying to connect to the college campus wifi network, but having difficulties in Linux.I am dual-booting Windows 7 and Ubuntu 10.10, and I use Google Chrome web browser on both. When I boot into Windows, my laptop connects to the network (as I can see from the taskbar icon) and I can (and currently am) connect in Chrome.However, in Ubuntu, it connects (or so the icon indicates) but Chrome doesn't load any pages.The campus network is unsecured, but once you open the browser, you are prompted with a log-in page (student ID and password) to actually connect.Here is my output for iwconfig:
wlan0 IEEE 802.11bgn ESSID:"sjsu_campus"
Mode:Managed Frequency:2.412 GHz Access Point: 00:24:6C:BC:D3:E0
Bit Rate=54 Mb/s Tx-Power=20 dBm

I've got Ubuntu 10.10 loaded on my HP mini, and haven't had any problem with wireless connection before. But since I've started going to my local community college, I've been completely unable to connect to the campus-wide wireless network save for once. I don't know anything about the network other than that it has no encryption.
I have only attempted to connect, thus far, using Ubuntu's built-in autoconnector. Is there a way that I can see what issue it's having, maybe get an error output? The auto connector can't seem to negotiate a DHCP lease, it just times out trying to talk to 255.255.255.255 on port 67. I can't think of why this would be, no one else I've talked to with a laptop has any problem connecting. Is there some, more sophisticated method of working out an IP address that Windows/Macintosh knows to do and Ubuntu doesn't?
discover HOWTO for an on-the-fly "campus" wireless network? I will be part of a large youth sports event spread over several acres of grassy fields. I need a wireless network for the event operations and administration. I want to operate a private wireless lan, "under the stars" with a few puddles of kiosks participating.
Some of my thoughts:I need some sort of antenna for outside use with wifi.
I need a primary wifi access point.I could use a wifi router & access point to connect with the primary for each kiosk puddle.I could use a pair of wifi router & access point boxes, with directional antennae, as point to point.phone and tablet and pda and laptop boxes, in the hands of staff,could use this private wifi lan for event operations.I could put a LAMPP or XAMPP server someone on this lan for event operations The server could have a connection to the public internet somehow
If I used one of the linux open-source wifi box, hotspot images or similar, I could manage this lan as a group of steamer-trunk, drop and setup stations.
I have had a heck of a time trying to get my laptop running ubuntu to connect to my home network. I have managed to get it to work at my university which would seemingly be more difficult than getting it to work at home, so I know for a fact it isn't a hardware or driver issue. If I try to connect via ethernet cable from my router, it detects that I connected the cable but says "disconnected" and never lets me connect. If I SKIP the router and go from my modem directly to my laptop via ethernet cable it works great.
Using the wireless network tool I can see all of the wireless connections in my area. When I go to connect to my network it prompts me for the WEP key and when I enter it and hit connect it just keeps cycling and eventually times out and finally again prompts me for my WEP key. I know this network works as it works just fine on my Windows 7 partition. Another interesting note - both my wireless and ethernet connections both worked flawlessly and stoopid easily on the live cd but don't after the full install.
If I manually enter in the information for my wireless through IPv4 settings and enter in the Address,Netmask and gateway I can connect to my network - but then I have no active internet connection. Same deal with my wired connection. Is this because choosing this manual method grays out the DHCP?
I have a problem which is connecting automatically to my spwireless. On my windows, my schools provide me the disc which contains several .cer files and a automated batch files to copy the .cer files to the root folders. I can choose to use the other network but in using that, i have to manually connect compared to using the spwireless. Anyway, my problem is that, how do i add the .cer files and to where so when i connect to the network it will look there for the cert. Because when i manually connect, only one cer can be chosen.
I recently went back to Linux on my netbook because Windows 7 was too laggy (1gb of RAM, go figure). I've never been able to connect to the protected wireless network on my campus without using Windows, though, so I was hoping someone could help me finally get that figured out.
The school has a how-to for connecting to the network using various operating systems, including Linux, here (scroll down to the bottom to choose OS). After following the guide through the CA certificate it mentions, the network manager tries to connect for a while then just sort of times out and asks me to enter the information again. Using Wicd, I noticed that this timeout appears to happen when trying to obtain an IP (after authentication).
My system: Acer Aspire One AOA150 with an Intel 4965AGN wireless card (installed by me a few months back, have had no problems with the card itself not working). I've installed Kubuntu 9.10 Netbook edition and done all available updates. My campus offers an unprotected "Visitor" network that I can connect to without issue, but they limit what you can access using the unprotected network so I need to be able to connect to the WPA2 one.
I've tried getting help from on-campus IT but keep getting told that none of them know how to use Linux, which makes me wonder who exactly wrote the how-to on their website... The guides on the website are for older versions of Ubuntu, but I figured they would remain applicable on a later-version Kubuntu install.
The more I use Windows, the more disgusted I get with it lol. So I would really enjoy using Ubuntu on campus instead of Windows, but I can't seem to get it to work. They have PDF files explaining how to connect with Windows XP - Windows 7 and Mac OS X, but nothing for a Linux distro. Here is the link to the PDFs [URL], and here are the settings I've tried to use to connect [URL] . I know that the CA is right (unless I need to us the Ubuntu version).
I 'm using fedora 10 on my laptopI can connect to the wireless network at home where I use verizon router WEP Hex 64bit Open environment.on the campus the wireless is WPA2 , PEAP. I follow their guides here:and I have tried both methods , one is for fedora 8 , the other is for version 10. but with no luck at all.the wicd seems not even to try to connect; Network Manager tries to connect each time I let it; but every time fails
I upgraded to Maverick over the weekend from Lucid, and at school yesterday, I could no longer connect to the campus wifi network in my office. I have no problem connecting to the wifi network at home, and my phone still sees and connects to the campus wifi network, so I think the problem is with my laptop (Gateway T-6345u), which doesn't even detect the campus network. As of last week, it connected automatically, and now it can't even see the network.
I'm trying to setup a wireless AP with my old asus eeepc, so it can act as a repeater to connect my android device on the other end of the apartment. I've already created the Wireless Access Point using hostapd. It took very little configuring, just changed from mode 'a' to 'g' and changed the channel from 60 to 1 and It was all set. Next I setup a dhcp server. Also simple enough using yast.
Up to this point, I was able to connect my android device to the newly created wireless network. However It doesn't have internet access. I guess I have to configure iptables for this, but I find it incredibly confusing! Here are a few specs to help with any examples: The laptop is connected to the internet through eth0 with IP 192.168.2.120 Hostapd is using wlan0, and I'm pretty sure it created mon.wlan0 So, to sum up, when I connect my android device to the network I can, for instance, see what ever pages apache is currently serving on the laptop, but can't access the internet.
Just today I installed opensuse 11.3 on my Compaq CQ61. Even though I am able to connect to networks (both with an ethernet cable and wireless) I don't have internet access. I have used opensuse for a very brief period in the past and I had no such problem.
I want to connect to a wireless open ad-hoc network to have internet access. It worked a while ago (1/2 year or something) but some update must have messed something up so it doesn't work any longer. Situation: There is a laptop that is running windows 7 and is connected to the internet via cabel. A open ad-hoc network is configuered with sharing of internet connection, status of the ad-hoc network is "waiting for users to connect". I want to connect with a second laptop that is running ubuntu 11.04. I can find the network and connect to it.
Problem: I cannot get any internet access while being connected to the ad-hoc network. So my questions are: how can i find out if what causes the Problem? I suspect a driver issue, but I'm not sure. required information from Howto post a wireless issue:
Running Ubuntu 9.10 Ive just got my wireless connection working after first having got the wired eth0 connection working.
With the wired connection I could SSH into my server through my firewall/router (via a forward). I can run up VNC, from there firefox, browse the web - all is well.
I have now setup the wireless connection, using a static IP, and I can likewise SSH into my server. I can run up VNC. I can ping my router. I can log onto it via VNC. I can browse to my router. But I cant browse the internet.
But I cant ping google.com. The reason is there is no host lookup service. Nslookup eventually says no servers could be reached.
So specifically, if I ping www.google.com Im told "unknown host". If I do an NSlookup on it I get timeout, no servers could be reached. However if I ping 188.8.131.52 I get responses.
I see no relevant entries in my firewall log.
Unfortunately I cant traceroute because the package isnt found - and of course I cant install it because I have no internet !
Strangely (to me at least !) if I then tunnel through SSH and browse the web, I have no problems. It works ? I know I am browsing through my SSH tunnel because whatsmyip gives the IP of my router at home, not where Ive SSHd in from. I can surf just fine.
why I cant do host lookups any more (and this did work with my wired connection, but whether its related to my change to wireless, or static IPs or both I cant be sure - it certainly appeared to happen at the same time). And, more to the point, what I need to look for/do to rectify it ?
As a bonus Id be interested in why I can SSH and browse via tunnelling but not direct from my server (via VNC). Just for interests sake !

I have a dual-boot desktop with Windows 7 and Ubuntu.Problem: Linux does not recognize my D-Link DWA-131 Wireless N USB Adapter. So, I can't access my wireless router or the internet.D-Link has a Linux driver for the DWA-131 posted on their website URL...that includes a readme file with long, strange, convoluted instructions on how to install the driver.
I had been happily using a wireless connection for about two weeks. The connection then went down for a few days. Since it came back up, I can connect to the network, but cannot access the internet. Other users of the network can both connect to the network, and access the internet, though people have experienced the same problem as me the last time the network went down (they could connect to the network but not access the internet). I have tried deleting and re-starting the connection, to no avail. I have looked around the forums, but haven't found anything that can help: do any of you have any suggestions? I am malarial and at the end of tether.It is not a problem with Ipv6, which is set to ignore, as it was in the past when the connection workedI am running Ubuntu 10.10 on an X61 Thinkpad. Below is the output of iwconfig, route -n, lspci, and what happens when I ping other network

I just loaded Ubuntu 11.04 onto Acer Aspire 5100 computer. I can access the internet through Firefox when I connect ethernet lan cable but it doesn't work when I use wireless connection. Although I do get the indicator in top right that says my wireless connection was established. Why I can't access internet with Firefox in wireless mode? I tried toggling the wireless switch in front of Acer but that didn't work.
I have installed ubuntu 10.04 and STA wireless driver. I am using a wimax modem, the wireless is connected (have IP addresses) but I do not have access to the internet.I also have installed a windows XP as a guest OS (ubuntu is the host) on vmware. By using a bridged network connection, I am able to access internet. So I guess the problem is related to the ubuntu wireless driver.
I am attempting to connect Ubuntu 9.10 to the Internet.I have a network connection, and Karmic detects it fine. I can ping addresses within our network (e.g. the Windows computer in the next room), and I can ping the router, but if I ping, say www.google.com, it says "Destination Net Unreachable". Previously, in Jaunty, I had a similar problem.I found a workaround: launch Pidgin. Somehow, launching Pidgin temporarily edits my configuration. However, in Karmic, I have no access to Pidgin, however, and Empathy does not do the same thing. Since I have no Internet, I cannot "sudo apt-get install" anything.How can I get the Internet working?
With Encrypted Wireless Connection Not Able to Access Internet - no pings, internet browsing, etc. However, without encryption I am able to browse the internet. I need encryption ..
I am pasting diagnostics collected by shell procedure collectNWdata.sh..

I spent $70 on a brand-new Wireless-N adapter for my Ubuntu computer in hopes that I could get it to connect to the main router in the house and get me internet access. However, the driver install CD is designed for Windows and thus will not run. I have tried to get it to set up, but it takes no action when plugged in and I am still without access to the internet. what I can do to get my computer connected and save me from having wasted $70?
At work, we (like almost everyone) are still full-on windows. I am currently trying to get away from windows because I am not a fan. my current windows machine (different from my Ubuntu machine) is accessing the wireless network fine, and there are no obvious problems there. Also, my Ubuntu machine can access my wireless network at home, so I know there are no driver issues. I set up the connection for the Ubuntu machine, and it seems to be connecting OK. I can ping internal IPs and by all statuses, the connection to the router is functioning. However, when I attempt to load a web page or ping a domain or external IP, it fails. I tried to ping the IP, thinking if that worked, it's probably the DNS, but pinging both domains or IPs fails. I have looked around at forums and posts, but none of them seem to match my issue (that's probably not true, but I am struggling to see the commonality).

I am building a CarPC which I'd like to have wireless internet access on. I have Verizon phone service so if there is a Verizon air card (not wireless card, an air card so I can have constant access without having to search for hot spots) that would work with Fedora 10 I would be very happy. I don't really know where to start and I can't find too much on Google, so I'm just looking for what options are available.
I started using Arch just a few days ago. forward traffic to the Wireless access point I created on arch. i am using cable internet (ppp0) which I want to share via a usb wifi adapter running as a WAP. I followed the instructions in this link to enable the AP mode. Afterwards I followed the instructions provided in the Arch Wiki to forward the traffic but because of my inexperience I am still unable to connect to the internet. Here is the output of iptables -nvL :
