Ubuntu Networking :: 10.04 - Exclamation Point (!) Next To Wireless Icon
Jul 21, 2010
There's an exclamation point next to my wireless icon up at the top which concerns me. I've just installed Ubuntu 10.04 yesterday - absolutely love it. The only problem is that I'm having trouble with staying connected to my wireless network... When it is connected, there is an exclamation point next to the wireless icon.
I have Broadband internet, Belkin N Wireless router, and an Acer Aspire 5741 with the wireless device built into the laptop. This normally runs fine with Windows 7, but it doesn't automatically connect with Ubuntu 10.04...

I got a NetGear wireless router recently. Attached it to my Huawei (pardon the spelling) modem. I have a HP 540 laptop running Ubuntu 10.04 The wireless gets connected. But there's an exclamation mark almost all the time. Very frequently these days, the connection gets bogged down or websites just don't open at all. But the icon (with the exclamation mark) shows Active Connection. I don't know where to start looking for bugs. Seems odd. Wireless is connected, I can connect to sites, but there's the exclamation.. and sooner or later, connection goes off but the icon still stays the same with "active" label.

one of these "WiFi works in Gnome, not in KDE" threads, but I have been all over google and hundreds of threads across different sites and can't figure this one out.As mentioned, wireless is peachy in Gnome, unfortunately I like KDE and I'm more productive using it (when I have internet). Wired network works fine in KDE, and my network card
Code:
03:00.0 Network controller: Intel Corporation Wireless WiFi Link 5100
Subsystem: Intel Corporation Device 1201

3 computers in the house run various windows based programs and everything is fine with them connecting to the internet as far as putting in the security password to log in and get online.My old back up computer that I use in the basement that has Ubuntu 9.10 was working fine with the secured network situation up until today.I booted up the computer this morning and it automatically connected as it typically does and I was reading some email and then the computer froze, which on rare occasions it does.
Upon reboot I got a window that asked for the password for the Network Manager Applet which I supplied and then it asked for the password for the secured internet connection which I supplied.It would not connect. After numerous tries of disabling the wireless and enabling the wireless and entering the Network Manager Applet password and the secured internet password I still get no connection.
I notice that when it is trying to connect, the window comes up on the screen that shows that there is reception from the modem, but there is also a little "lock" icon like I'm locked out of the connection.I finally found a way to get rid of the Network Manager Applet password problem but that still didn't alleviate the connection problem.

I have a Sonicwall access point, which I am able to set up through the interface, but after that I am unable to achieve a connection through my wireless card. I have a good understanding of everything involved, but really have no hands on experience when it comes to networking.
Code:
lspci
00:00.0 Host bridge: Silicon Integrated Systems [SiS] 735 Host (rev 01)
00:01.0 PCI bridge: Silicon Integrated Systems [SiS] Virtual PCI-to-PCI bridge (AGP)
[code]....
Also, I should have mentioned that @ the interface for the Sonicwall it said that "no DNS server had been specified", but I set it up for DHCP, and I thought my ISP is using PPPoE (which I also thought used DHCP).

I'm trying to set up a wireless access point and router using Ubuntu 10.10. My machine has an Atheros AR5001X+ PCI card, and eth0 is connected to an ADSL modem.After literally days and days of going in circles, I'm hoping that somebody here can help get me on track.This sort of works, though I had to go through some other contortions to get the madwifi driver to finally compile on my machine.At this point, I can see and connect to the WAP, but nothing more. When I try "sudo /etc/init.d/networking restart",
I also have a second problem, which is that I want to use WebMin to manage this server, but I cannot figure out how to get the ADSL client module configured -- RP-PPPoE version 3. It seems to expect to work with pppoe-start, pppoe-stop, and pppoe-status, but when I try to run pppoe-status it says "Link is down", even though my ppp connection is actually working.Is is possible to use the WebMin ADSL client module with Ubuntu? I spent a lot of time trying to get pppoe-start, stop, etc. working but it was a complete mess and never seemed to behave. Finally, I just put the ppp startup commands into the /etc/network/interfaces file and that worked, but now the pppoe-* commands no longer seem to function.

I installed it alongside Win XP, using Wubi, and it seems I use Ubuntu 10.04.Everything worked out as expected, and my wired internet connection works like a dream.However:My wireless connection seem a little buggy.I can see all networks (except WPA2) so even if I want to fix the WPA2 problem, I'd rather just open my network for now.
So my network is now open, I see it in the NetworkManager list, and as i try to connect, the following happens:The wireless symbol start flashing. From here it keeps flashing, untill it gives up.I use RT2870 drivers, and D-Link DWA-140 USB wireless adapter.
It goes without saying I am a freshman regarding Linux, so if anyone knows what to do, and cares to take the time to tell me, please do tell me in a detailed manner.I do know the basics of the Terminal, and yes, I do know how to copy/paste commands I find linux way more satisfying than Windows so far ... And thanks in advance for giving away your time More info can be given upon request (You might have to explain how to find that specific info)

I'm going to be working in an office with no wifi and no 3g signal but my laptop will be connected to the web via a wired network.Any way I can use the wifi card in my ubuntu laptop to create a wireless access point so my phone can connect? Would have to be easily selected and deselected as I'd then want to use wifi to connect to the internet at home.

I'd like to create a wireless network so that I can connect my iPhone to the internet. I made a new network, the iPhone sees the network and apparently connects, but Safari doesn't work. It doesn't work with the default settings, and I don't know what to put in the fields. Could anyone give me a small tutorial?

I am in a situation at the moment which means I am going to be without an ISp for a week or two, and I can't survive that long without the intenet!!! What's more, I have 8 computers that need to connect, though not necessarily at the same time, but certainly more than one at a time. Anyway, I came up with an idea to buy a Mobile Broadband Dongle, and then share the connection via my PC. Problem is, I don't know how I would go about setting my PC to be a Wireless Access Point/makeshift Wireless Router, and sharing the connection.

I have configured my router to behave like a wireless access point. I'm using hostapd as the utility to manage the access point. I am able to connect to the access point from my android phone.Now i need to send a file to the android phone from the access point.

I'm trying to setup my ubuntu server as an access point but am running into some issues.
The server has an Atheros wireless card (AR5008 chipset) and I have used the following link to set it up in master mode using madwifi drivers: [URL]
I then used this link to set it upas an access point using hostapd. [URL]
But inspite of following the above steps, other wireless clients in my LAN are unable to see the ssid "Linuxmaster"
Although iwconfig shows that the card is in master mode.
iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
wifi0 no wireless extensions.
ath0 IEEE 802.11g ESSID:"Linuxmaster"

10.04 in a couple of identical lenovo laptops (of friends) suddenly have stopped connecting successfully to wireless, coinciding approximately with a mains power socket fail at the modem router, now fixed. presumably the machines were trying to connect to the access point, which may or may not have been working, but themodem router was not. Now, internet connection and wireless access point is fixed ok and is back up, and i can connect wirelessly to the access point ok using an eeepc with 10.04.2 with no problem so the access point is working ok
the target laptop/s are still ok via wired ethernet, and can *also* connect to a neighbours open wireless (a british telecom so called fon network, it asks for an account password), and all local wireless networks can be seen normally, and the home access point ssid can also be seen ok. so the aptop wireless is connecting ok, but not to this particular access point now. maybe someting has got screwed up? it is wpa2 and when clicked, after a long-ish time, the authentication is requested, then given, correctly, and still not connecting, asks for authentication again etc etc. no local secure wallet is being used.
when upgrading these laptops for my friend some time ago from 9.04 i have a small recall that 10.04 had a odd thing with wireless authentication (?) bug? i have deleted the network connections gui listing for this ssid and restarted the laptop, still no joy.

Now on this Motherboard, I also have a wireless nic that I have no plans on usin. Can I turn it in2 an access point/wifi for other devices like iPods, Wii, Labtops, ect?Also, how would I do it if not Wifi, use the other Ethernet port to plug up say a labtop. In which the labtop uses the net I am getting from the router?

I have an Intel PRO 2200BG wireless card and can connect to my router when logging in via gdm (using Xubuntu.) No problems there, connection never drops, very reliable!
But I've since had the need to shutdown X and keep a simple terminal instance open but as soon as I stop gdm the connection to the router drops. Trying to connect via the terminal using wpa_supplicant has so far been unsuccessful.
I know for a fact I'm doing something wrong, just don't know what and would appreciate some help!

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 :
Code:
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

====== Wireless Access Point & IP Forwarding Mini-Howto ======Use case: we have a pc (laptop, for that matter) with UBUNTU 10.04, and with wired connection to the internet. We want to connect iPod/iPhone or any other device to this laptop, and browse the internet, effectivelly turning our pc/laptop to a WI-FI access point. At this stage, we would not implement any encryption, so our network would be open to anyone.
Oour pc/laptop have 2 working interfaces, wlan0 and eth0. Device eth0 is the wired connection to the internet, device wlan0 is going to be set up as the wireless access point for the iPod/iPhone or similar gadget. We want to forward any IP traffic attached to wlan0 through to eth0. Interface eth0 can either obtain the IP addres from DHCP server on the router, or it can be fixed, it does not matter. But we definitelly need to set fixed IP address to wlan0, and configure dhcp server to listen on this interface.
===== Things to do =====
configure iptables to forward the traffic from wlan0 to eth0
setup wlan0 in /etc/network/interfaces

I have Ubuntu command line only installed on my HTPC (it is XBMC Live installation). Kernel is 2.6.31-16-generic. My wi-fi card is AW-NE770 from AzureWave (mini-pci on Zotac Atom motherboard). I have successfully configured wireless connection to my router. Unfortunately, after short period of time connection drops. When I restart /etc/network/interfaces all goes back to normal. When connection is dropped, iwconfig shows that access point is not assigned. I have already tried installing backport drivers, removing security on the network (WEP and WPA), assigning static IP or using DHCP. Nothing works. I know it is not the router or my internet because I can be at the same time on my laptop and that works fine.

I have a windows 7 (64bit sadly) desktop computer with no wireless capability. Now before I go out and spend money on a wireless usb thing, I was wondering if I could use my laptop (Ibm think pad T60 running ubuntu 10.10 dual boot with crunch bang) As a wireless access-point and connect via Ethernet cable the laptop to the desktop (Probably through a modem?) so I can use the Internet for games on the desktop computer. (Games that wont work in wine, sigh). Just a note though, 64 bit windows 7 will NOT run anything.

I'm trying to make my F10 Laptop a wireless Access point.
When I 'iwconfig wlan1 mode Master' I get:
SET failed on wlan1; Invalide argument.
wlan1 is a Netgear WG111v2 which worked as soon as I plugged it in after I installed F10.
I don't know is it not supported? What is? Is there a different driver I can put on that will work in master mode.
What should I do basically?

I'm new to Linux and I have a problem with the Wireless connection.I've already searched for this problem but found so many threads it was impossible to sort it out.I've just installed Fedora 13 (Live CD - Install to Hard Drive) and apparently it's kinda... "empty". But my problem is with the wireless connection. There is a free network provided by my city for all the citizens. It is Open (authentication) for all. The problem is I can't "see" the network in Feodra. In Windows 7 I can "see" it just fine with 3 bars signal strength. It is great for surfing and emails. It is not intended for heavy downloading.
Why can't I "See" this network? There is another weird thing. The neighbor above me has a Wireless access point closed of course but I get 44% signal strength in Fedora and Full bars in Windows. Does it have to do anything? Maybe the low signal of the free network is the problem and Fedora makes it disappear completely?

The garage in my house is a dead spot for my current wifi router.I can't get a signal there.Moving my router within the limits of my cabling doesn't fix it. But I have two other routers I'm no longer using.Is it possible to use one of them as a wireless access point to extend the range of my current router?If so, what is the general procedure for doing that? My main router is a Verizon Actiontec M424WR. My other unused routers are a D-Link and a Netgear, both of which have wireless capability. The Netgear had a superior range, as I recall.
