wireless connects to router but not internet

briholt · Post by **briholt** » Fri Aug 01, 2014 3:53 pm

I've ifconfig wlan0 down and up but still no joy. Same for dhclient.

I don't know where to go next.

Suggestions?

One oddity is that with ifconfig down I'm still connected to the router. Shouldn't it be, ya'know, down?

Thank you for the stupid question (which is really isn't).

I am able to access the internet on other machines. In fact, this is a dual-boot machine that I'm having trouble with. Currently I'm in the Window's partition while writing this post and internet access is solid.

So, FYI, dual boot, win 8.1 and linuxmint 15 olivia KDE

Here is what I have with the iwconfig:

ok,

let's try to run this script to collect more info (don't worry it will only display your internal LAN witch is the same for 99% of home users, I bet your ip starts with 192.169.x.x and your router has 192.168.x.1?)

Code: Select all

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script

you will have to be connected to get the script (ethernet)
Actually can you connect Mint with ethernet?

I just downloaded the script using my Windows side and then switched over an ran it...so, here are the results (sorry for the wall of text--this site wouldn't let me upload an attachment with .txt)

Also, for what it's worth, I'm thinking of getting a newer release of mint. I just saw the announcement that if one has 14, 15, or 16, one should upgrade to 17.

what encryption are you using on your access point?

Also delete your existing wifi connection and do a new connection. maybe some corruption in the settings.

DrHu · Post by **DrHu** » Sat Aug 02, 2014 2:58 pm

You can try a quick setup via wireless controls from the command line, and also consider using a static (fixed IP) setup to ensure a connection, if the wireless device seems to work on the Linux side
--you do say you get something, so it is just the IP address of the client that is the issue..
http://www.ghacks.net/2009/04/14/connec ... mand-line/

The other vway of tackling it is to look at the settings that windows OS uses, specifically the GW (Gateway IP address) the password
--which for the encrypted connection you use, should be known to you..

Had to do with intermittent connection issues and stabilities of that chip; still could be worth a try..

And one other question; do you also have an Ethernet (NIC) PCI card included in the BIOS of your machine
--if you don't use it/Ethernet wired, disable that PCI Ethernet NIC in the BIOS and test your connection again.

When I encounter that same situation, I check that /etc/resolv.conf has 192.168.1.1 as nameserver. After ensuring that the connection works I set my dns as I wish. But for the test I always enter the router ip

PatH57 · Post by **PatH57** » Sun Aug 03, 2014 2:46 am

Hi,

to check DNS you could install namebench (package manager) and run the test.

That didn't make a difference, if I deleted it in the way you are thinking.

How does one make a fixed IP to ensure connection?

--you do say you get something, so it is just the IP address of the client that is the issue..

Sorry I'm not good with the lingo, but who is the client? I can ping my router, but that's it, from my linux partition. Currently I'm on the same machine, same hard drive, different partition though using win8.1, and I can access the net fine.

I'll take a look at those other links. Maybe it is the realtek card. what is aggravating is that it was working fine for months and then suddenly...

Also, I don't know about the BIOS settings for a Nic. I don't recall seeing one.

Check it because if I drive by your house I'm in your network in about 2 hours. I knew I saw something funny in your layout.

You are not using a secure connection. Double check your router settings.

Okay, I've been using wpa. Currently using an ethernet connnection.

despire what that code says, when I login to my router, the wireless is clearly using wpa and wpa2 security. Also, other devices (TV, windows, iphone) are prompted for a password to connect.

If I do

Code: Select all

sudo  ifconfig eth0 down

my ethernet connection to my router, and the internet, stops promptly.

If I

Code: Select all

sudo ifconfig wlan0 down

nothing happens, in that I still am connected to my router.

briholt · Post by **briholt** » Mon Aug 04, 2014 1:40 am

Well, still stuck.

Ran the namebench and took its advice to change some DNS settings.

Still no joy. My noob hunch, based on reading the links shared here, is that it's related to the driver.

But what I don't understand is why it stopped working. I also don't understand why "ifconfig wlan0 down" doesn't actually disconnect the wireless connection with my router.

seems you have on ralink card that doesn't work very well with the default kernel driver.
Let's first try the patch and see if it works.

Installation

Ensure you have the necessary prerequisites:

Code: Select all

 sudo apt-get install linux-headers-generic build-essential dkms

Clone this repository:

Code: Select all

git clone https://github.com/pvaret/rtl8192cu-fixes.git

Set it up as a DKMS module:

Code: Select all

sudo dkms add ./rtl8192cu-fixes

Build and install it:

Code: Select all

sudo dkms install 8192cu/1.8

Refresh the module list:

Code: Select all

sudo depmod -a

Ensure the native (and broken) kernel driver is blacklisted:

Code: Select all

sudo cp ./rtl8192cu-fixes/blacklist-native-rtl8192.conf /etc/modprobe.d/

And reboot and check it.

THanks for your help, Pat.

I think I tried this route from a different thread, but am going forward with your step by step.

One thing I noticed, is that the current git branch has a 1.9 version, while your command

Code: Select all

sudo dkms install 8192cu/1.8

has a 1.8.

Rebooting now..
