Cannot Connect to Wireless in Linux Mint
So this is a problem I've been having for awhile. first started with Ubuntu. I installed it on my new PC and the internet worked fine for awhile. Then suddenly one day it stopped. I couldn't connect anymore.
I didn't know what was wrong or what to do. Tried looking online for a solution but found none. I decided to try and install another OS thinking the problem would sort itself out. I installed Linux Mint (Cinnamon) only to run into the same problem. On my desktop it says I have no connection. It still detects the house wireless and my neighbors networks. When I try and connect to the house network it says "Connecting to the wireless network..." for a few moments before a notification pops up that says "Disconnected - You are now offline." When I open up the browser it says "Server not found." I read somewhere that when asking for help with problems like this it's best to go into the terminal, do some checks, and post the results. Since I can't get on the internet on my PC I just took some pics with my phone so I apologize for the quality: "sudo /usr/lib/linuxmint/...": http://i.imgur.com/78sHrpZ.jpg http://i.imgur.com/pFadQiH.jpg http://i.imgur.com/Xl2gbdZ.jpg "lsmod": http://i.imgur.com/wIdiqS7.jpg http://i.imgur.com/WDQsmWK.jpg http://i.imgur.com/sJLlFN7.jpg http://i.imgur.com/bcI9CQu.jpg If you need any other information just ask. |
Hi
so that also tells us you have no dual boot. but there may still be options of loading a live cd/dvd, did you know that? some observations first ######################## thanks for the images we can see 2 main kernel modules that may interest you wireless appears to be rtl8192ce and altho I have a debian link https://wiki.debian.org/rtl819x#supported-rtl8192ce I would like you to open your terminal again as a local user (not root) and run this command pls Code:
lspci -vvv Code:
PCI: 10EC:8176 Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter look at the numbers to the left side 8176 to 91......tell us the number you see in your command ###################################### also we can see you have a wired kernel module called r8169 do you have a ethernet cable that will allow you to connect router to computer? ##################################################### finally for now open a terminal and run the command with root powers, LM I think uses sudo for that so shortly you run (sudo command) and when prompted put in your local user password not the root password -----confused yet? here is the command Code:
sudo ifconfig if LM has a package manager such as aptitude or whatever either open a terminal as a local user and type Code:
wicd- hopefully you have installed wicd-gtk http://community.linuxmint.com/software/view/wicd-gtk and you can use it to scan wireless networks good luck |
separate post
can you name the live cds or live dvds of linux you have pls? |
Mint is debian, so it should have aptitude (apt-get). I concur that the wicd package has the best probability of success.

First off, I don't have any "live" cd's/dvd's. Don't really even know what those are. I don't even have a disc drive in my PC. I installed Linux Mint through a USB. -------------------------------- When I put in that first command it gives me a long list of stuff but nothing arranged how it is in the quoted area. I do see mention of the kernal driver you mentioned (rtl8192ce) and "Realtek Semiconductor." Not sure if it's suppose to come out like you quoted it or if I'm suppose to sift through this information dump. I could do that but it'd take awhile. Could also be because I'm not 100% sure I'm doing this as a local user or not. I'm just logging in and selecting the terminal icon. If I'm doing it wrong tell me. I'l post a pic of what my screen looks like. Won't post the entire output unless needed because that'd be a lot of pictures. http://i.imgur.com/P25sHOD.jpg It's just a bunch of sections that look similar to that. ---------------------------------- The router is in another room and I can't move it as it doesn't belong to me (I'm a renter). I could possibly run a long ethernet cord to the next room where the router is but I'm pretty sure my landlord/s would have an issue with that. ---------------------------------- Posting a picture of what the ifconfig command gave me. I assume because there are so many 0's in "eth0" and "wlan0" sections that means they're not active right? http://i.imgur.com/IpcRFZN.jpg Sorry the image kind of cuts it off. First section is eth0, second is lo, third is wlan0. ---------------------------------- I tried the wicd- command and no command was found. This could also be because I'm just logging in and selecting terminal and I'm not sure if that's doing it as root or as a local user. It did try and corrent me and ask if I meant "'wicd' from package 'wicd-daemon' (universe)." When I just type "wicd" it says the program wicd isn't installed and gives me a command to install it. Should I go ahead and try it? Same goes for "wicd-gtk" which you mentioned. I'm guessing even if I tried I couldn't install them because I'm not connected to the internet? Or am I wrong? |

2) I am grateful you care about your landlord, you sound a nice person so I hope I hold my end of the bargain 3) how are you connecting to the internet on your replies please? 4) do you have spare USB stick leaping ahead, pretending you do not have wicd-gtk installed, we could provide a link to it you use (say) windows to download it to usb use root powers to move it onto (say) linux usb or linux hard drive and install it ----as you can tell, I live in australia so sorry for not instant replies others feel free to offer advice please 5) ok so lets just confirm some things first ok? no need to take photos just tell the results, if no hits you won't get a hit list like mine run this command as a local user Code:
dpkg -l | grep wicd 5) can you confirm you ran wicd-gtk and got pop up box = gui = executable 6) now the next a few steps to be done in order first we need you to stop the ethernet from interfering with wifi Code:
sudo ifconfig eth0 down ----you want to see only lo (local) and wlan0 leaping ahead now we want to check what LM thinks, I googled this http://forum.linuxmint.com/viewtopic.php?f=53&t=116943 don't get too excited about all the crap in there just run this command Code:
sudo mintWifi depending on your answer or others dropping by to help we may need to give you links to wicd-gtk? good luck |
now as far as I can tell, LM is supposed to run a program called networkmanager
and its supposed to have an icon visible to you can you confirm pls is this what you used in the first post? If it is, it sounds like you just need to give it the correct encryption passphrase and SSID stuff? try right hand clicking it and looking for a settings option good luck |
Hmm, Though I don't run Cinnamon. Maybe I can help.
My Laptop Code:
$ inxi -Fxz Code:
$ inxi -n I am more of a minimalist and this is as blingy as I get. Besides XFCE. http://askubuntu.com/questions/21630...s-to-reconnect http://bbs.archbang.org/viewtopic.php?id=3163 Maybe but I really don't know Quote:

shows that you are recieving a IPV6 adddress on your wlan interface. You can easy check it at any time with the following command ifconfig wlan0 Maby you must disable ipv6? Log in to your router and chech that its set to auto and not a specific channel, my lubuntu did not want to recognize my ap after changing it to ch 11 but ubuntu 10.04 did, changed it to auto and there where no problem connection from both of them. If its set to auto try changing a channel it could interfeer with one of you neighbours. Before changing any settings check if you can ping a couple of hosts in the internet 8.8.8.8 for an example. You can also share you internet from smartphone and connect via the phone to se if there is any difference if you have a smartphone or maybe that was what you intended to use as internet connection? |

me thinks he can't log in to the router as its his landlord's 2) wicd-gtk is not an ipv6 daemon but OP has yet to reply in the meantime, I am looking at the dependencies in debian for wicd-gtk Depends: python, python-gtk2, python-glade2, wicd-daemon (without showing version numbers) the OP could check all but wicd by Code:
dpkg -l | grep python and pretending he only needs, if networkmanager fails, wicd-gtk he could use windows to downloand 2 files http://mirror.internode.on.net/pub/u....2.4-4_all.deb http://mirror.internode.on.net/pub/u....2.4-4_all.deb copy it onto usb stick boot up LM insert usb stick check with a file manager where is file -----eg /media/pathwayname/wicd-gtk* try to install it with Code:
sudo dpkg -i /media/pathwayname/wicd-gtk* change pathwayname to real name, in debian its /media/yourname/nameofusbstick if it works, do a full reboot as a local user run wicd-gtk and input landlord's WPA2 passphrase into the appropiate settings in that gui, wicd-gtk ############## according to distrowatch LM 16 has python pre-installed |

Yes you are correct its his lanlords router. Don't know what you mean by 2) wicd-gtk is not an ipv6 daemon but OP has yet to reply But the check the pic i sent you and look at wlan0 "inet6 addr" |
andy78
see that #692490 bug is not fixed until version of link https://launchpad.net/wicd/+milestone/1.7.3 my post 10 are versions 1.7.2 series |
Make a small test using you phone as wireless accesspoint (i asume you have a iphone or android based phone).

I am ordering a chinese android ETA 1-2 wks but my router is only ipv4, so will need a wifi hotspot to confirm |

Second, I do not currently own another USB stick save for the one. I plan on buying more in the future. If needed I can just reformat the one I currently own. I did the "dpkg -l | grep wicd" command and didn't get anything back, just a message that reads "dpkg: error: unknown option -1." No idea if I did it wrong or not. If you mean if I run the wicd-gtk command and get an install prompt I do. The prompt is in the terminal and doesn't come in a pop-up. If that isn't what mean than I'm sorry. Should I go ahead and try and install wicd-gtk just to see what happens? I did the "sudo ifconfig eth0 down" and it seemed to work as when I put in "sudo ifconfig" I no longer see the "eth0" section. Putting in "sudo mintWifi" doesn't seem to work. After a few moments it says "connection timed out: no servers could be reached." This is at section "VI." The section before that (V) just reads "querying DHCP..." and nothing else. Is networkmanager the icon in the bottom right that usually has the lined wifi signal? Where that is there's just a "no connection" thing. If not where would it be? |
