LMDE2 internet conn fail with 3.18.13-rt10mah+ was created by jtc
Hi.


I'm using a mesa 7i76E on a pc with LMDE2. with the preempt kernel 3.18.13-rt10mah+ kernel if I connect to the internet by an wifi usb adapter, after a few minutes, the internet freezes. I cant even do a ping, But using another kernel (3.16.0-4-586) everything related to the internet or wifi connection seems to be ok.

I did a lsmod on both kernels, that is he outputs:


this are the modles on 3.18.13-rt10mah+

If I do a lsmod when the internet connection fails, the output is the same, so at the moment I had no clue what can do this. any help will be welcome.

Michael will have probably built that kernel on Debian Jessie, but rt-preempt kernels are generally quite forgiving and transferable

..... I connect to the internet by an wifi usb adapter ......


Unless you say what the wifi adapter is and which chipset it contains, the list of modules does not help.

Run tail -f /var/log/messages when you plug the usb adaptor in to see what is reported
I got this plugging in a crappy old usb wifi stick( they are all crappy B) )

You also need to check you have the firmware for that NIC installed, (eg, firmware-realtek firmware-linux-nonfree )
which may entail fetching from sid or whatever to get the up to date ones.

Then remake initrd.img-3.18.13-rt10 to ensure it is up to date.
This is ancient, but the process remains the same

If i try to install with sudo apt-get install firmware-realtek or firmware-linux-nonfree it says that is already installed and up to date.

on the log i says: rtl8192cu: Loading firmware rtlwifi/rtl8192cufw_TMSC.bin and searching for this in google look liker its associated with firmware-realtek ( packages.debian.org/wheezy-backports/firmware-realtek )

rtl8192 is a pretty standard and well supported chip.
You seem have all the modules and firmware required.

I would be interested to see what gets posted in /var/log/messages and /var/log/dmesg when you have a problem with it.
Once you have the problem, go to a terminal and do

cat /var/log/messages > messages.txt
and
dmesg > dmesg.txt

and attach those txt files.

I am a little puzzled as to why the stick is coming up as wlan3.
That would suggest there are 3 previously assigned wireless lan connections in existence.

Please do in a terminal

cat /etc/network/interfaces > interfaces.txt

and attach that too.

Need to check which network manager you are using, if you have network-manager package and wicd installed, they conflict and can cause all sorts of problems.

Run
whereis wicd
whereis nmcli

If it finds both, you have potential problems right there.

the itnerfaces.txt file:

File Attachment:

File Name: interfaces.txt
File Size:142 B


Code:
cnc@cnc-pc ~ $ whereis wicd wicd: cnc@cnc-pc ~ $ whereis nmcli nmcli: /usr/bin/nmcli /usr/share/man/man1/nmcli.1.gz


the last thing that i did are update initramfs and install initramfs-tools. but after half an hour or so it freezes again...

I will post the log messages when the problem happens.

OK,

Your interfaces file just refers back to interfaces.d, which is certainly different to how Debian normally sets things up.

I'll wait to see what the logs contain, when you get a drop out on wireless.

There is nothing wrong per se with the modules and firmware, the dongle is being recognised and brought up.
These USB dongles are pretty flaky a lot of the time in my experience.

I tend to always use wicd for a much more reliable wireless connection.

Would be worth trying removing the package network-manager and installing wicd.
Just make sure you keep the dongle plugged in, so that hopefully it will be picked up automatically.

If it doesn't, you can normally use this procedure.
Code:
rfkill list all

If Wireless LAN is shown blocked (soft or hard)
Code:
rfkill unblock wifi

Then
Code:
ip a

which should give something like
Code:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether c0:4a:00:02:bf:d1 brd ff:ff:ff:ff:ff:ff inet 192.168.1.2/24 brd 192.168.1.255 scope global eth0 valid_lft forever preferred_lft forever inet6 fe80::c24a:ff:fe02:bfd1/64 scope link valid_lft forever preferred_lft forever 3: wlan1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000 link/ether 7c:dd:90:25:03:a3 brd ff:ff:ff:ff:ff:ff

Note wlan1 is shown as DOWN
Code:
ip link set wlan1 up

Now check appears in listing
Code:
ifconfig

Which it does
Code:
eth0 Link encap:Ethernet HWaddr c0:4a:00:02:bf:d1 inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::c24a:ff:fe02:bfd1/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:289154 errors:0 dropped:0 overruns:0 frame:0 TX packets:183142 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:361719392 (344.9 MiB) TX bytes:18481853 (17.6 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:2228 errors:0 dropped:0 overruns:0 frame:0 TX packets:2228 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1 RX bytes:5760967 (5.4 MiB) TX bytes:5760967 (5.4 MiB) wlan1 Link encap:Ethernet HWaddr 7c:dd:90:25:03:a3 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

Now check it is receiving and what stations are in range
Code:
iwlist scan

and you get something like this
Code:

Now you can open up wicd and click on the right hand drop menu [V]



Select 'Preferences', get this menu and add your WLAN desigination, in this case wlan1.



Then click OK and return to main dialog and click [Refresh], after which those stations you detected should come up and you are up and running once you select one of them and sort out password etc.



Note the strength of first station is 72%
That was 3ft from the router! Just shows how flaky these dongles are, my laptop gets 100% anywhere in visible range and 85% 15 metres away, behind 3 brick walls.
