General :: Can't Access Internet By Wireless Or Cable
Apr 23, 2010
I have installed Mint 8 on my HP Presario lap top. When booted up using XP I can connect to the internet wirelessly with no problem. But, when I boot up with Mint 8 I receive a msg that there is no connection to the internet. I then tried by hooking up to the router with a cable and it still shows "not connected to the internet" msg. I tried rebooting while hooked up with the cable and same result.
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 recently installed ubuntu on my mom's computer but I can't get the mouse to move trough the touch pad and I suspect the USB is not working either, because I can't get anything to work trough the USB, and the Internet is not working trough the cable, and I think wireless as well. Her computer is an old acer aspire 3000
I have a wireless card that needs the Broadcom B4311 Rev. 1 driver but I don't have a way to download that driver since I don't have wireless access since the driver isn't installed. I'm running Linux Mint Debian x64.
I have a linux box (fedora) with two ethernet cards eth1 and eth2. On eth1 I successfully configured a PPPOE internet connection. Such that from the server I can browse the internet. On eth2 I wired it to a wireless router essentially to provide the wireless cloud. On eth2 I also configured dhcp, such that the Linux box is both PPPOE and DHCP server.However my clients on the LAN cannot access the Internet.
On passing the routing command I get Destination Gateway Iface 196.44.x.y 0.0.0.0 ppp0 192.168.1.0 0.0.0.0 eth2 (my subnet) 0.0.0.0 0.0.0.0 ppp0.
The router (functioning as a wireless access point mainly) has a fixed IP address of 192.168.1.2 and eth2 has IP address 192.168.1.1. The dhcp file running on Linux has been set with option router (Gateway) 192.168.1.1. I cannot figure out how to correctly set the routing table such that my clients on wireless can access the internet cloud. I googled and googled but no solid solution. Any suggestions?
I use Linux Mint 10 and have been on Linux for about a year now. I'm no expert, but I can sort of find my way around. My problem is that I am not able to set up a LAN and share my internet connection through a crossover cable. I have a USB 3G data card for my internet connection, and getting a router for it is a mite expensive. I have a crossover cable and searching on the net led me to believe that I could do what I want to. The only problem is that I am unable to.I've got two desktops both on the same Mint 10 and when I connect them assign an IP address and gateway, my network manager shows that the connection is up, but I'm not able to ping the other system. I've even exited my firestarter firewall in case that was what was causing the problem, but I've not found a solution as yet.My knowledge of networking is at that dangerous stage where I know very little, but think I know a lot. What I've learnt about networking I've learned over the past one month when looking around for solutions to my problem but my basic understanding leaves a lot to be desired.
I'm having trouble setting up my desktop pc to access the internet via my wireless router. i have tried to set it up in networkmanager (it shows as connected when clicking on the NM icon) but when loading firefox or when trying to update opensuse i just cannot get a connection.
I have SUSE 11.0 set up to act as a router/firewall for my home network to the internet through a cable modem attached to an Ethernet card. When I was laid off several years back, I found information that let me connect my network to an ISP via a standard serial modem. I am considering going to the Sprint U1901 4G USB modem and dropping cable internet. Sprint claims the U1901 is Linux compatible. My thoughts are that using the 4G modem should be similar to the old dialup modem. I had a script that connected to the internet whenever internet traffic was detected. Unfortunately, I did not save notes on what I had done to setup the modem to dial automatically, and I have been unable to locate information that seems good to set this up again. I already know that all I had to do to get routing working was simply replace the internet port in the firewall/routing script with the port for the modem. So I assume that is rather trivial.
Would you please point me to a doc, perhaps SuSE specific, that gives reasonable directions on how to set up a "dial on demand" ISP connection? I assume that the 4G modem will be very similar to my old serial modem so that a dial on demand script will work. I did find a dial on demand howto, however, it did not seem to apply.
Over the past month my windows PC has been playing up, I therefore am using Debian on LiveCD to get used to Linux (before I wipe Windows completly). Ever since I downloaded Debian I havent been able to get the internet (wireless) working, well recently i have, but not for long... After 2 weeks or so of me pratting about, I found out sort of what the problem is, or how i can sort of solve it temporarly. My USB wireless card is Realtek RTL8187 and it recognizes it and works by default, Im sure its nothing to do with that, although KNetworkManager will never connect me, says Failed to decrpy WEP (in dmesg), even tho it's the correct HEX key, so I use Wireless Assistant 0.5.7 which does connect me, with the same key network-manager wont. Other than this I would manually set it and 'dhclient wlan0'.
So, to sort of get internet I will first connect to the network (obviously) and once connected, I will ping google.com, which usually will come back unknown host after a few secs, UNLESS I ping google, and quickly set the access point again, manually. So after i ping google i type "iwconfig wlan0 ap [ACCESSPOINT]" and google will reply, for roughly 3-5 seconds, and it dies again. After a few more frustrated days I decided I will test this to the max, so I simply spammed "iwconfig wlan0 ap [AP]; sleep 3; ect ect (over 50 times) and tried to update aptitude, epic fail. It took 3 attempts and over 20 mins to get 11% on packages (after i deleted the default sources.list and just added ftp server).
I personally think it's to do with the new Mac80211 drivers as the old ieee80211 stack drivers seemed fine for others and on BT3. Yesterday I downloaded Ubuntu to see if it would connect, it also uses Mac80211 drivers, but it DID connect with network-manager, but is very poor and dies after abt 20 secs max. Im not a big fan of Ubuntu but if worst came to worst I would have to install it (because crap net is better than none at all). My Windows PC is on the verge of death so I really could do with solving this.
Also, what older versions of debian, pref LiveCD's (if any) come with the old ieee drivers? If none what other Linux distro's (old or new) use the ieee drivers? (except BT3). Im quite new to linux so please dont mention compiling stuff, as the LiveCD doesnt have make by default. Also please note I can only access internet wireless so I cannot download extra stuff on wired net to see (although i could on Windows).
I have a dual boot in windows 7 and ubuntu. WiFi came with windows 7 but doesn't work at all in ubuntu.There are no drivers in my hardware drivers. I use one of those laptops that came with a built in atheros wireless adapter.
I have problem to access the Internet, with Ubuntu 10.04. In Windows I access the Internet in this way: Create a PPPoE Connection (with username and password), after this connect to a Wireless Network called WebSTAR (I have Wireless modem in my family PC), and connect to PPPoE Connection. After these steps the Internet works fine. .But I have same problems with Ubuntu. First I see the Network named "WebSTAR" but I can`t connect to it. And I try many times to join the Internet with "sudo pppoeconf" command in Terminal, but didn't work.
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.
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 126.96.36.199 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 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 :
Chain INPUT (policy DROP 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 77 31312 ACCEPT all -- lo * 0.0.0.0/0 0.0.0.0/0 0 0 DROP all -- * * 0.0.0.0/0 0.0.0.0/0 state INVALID
What distro is the easiest for a new person to get started? I also need wireless internet access. I've tried to do this once before with linux (mandriva as I recall, I gave up)before and had problems installing the programs that would allow that. Also are there Linux versions that I could install on my pocket PC?
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.
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 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 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?
