Hi.

Well I was very happy with my Linux Mint 18 Cinnamon, except, ... for the detail of the Wi-Fi connection.

The typical error follows this sequence:

1) Wireless network does not work
2) #sudo ifconfig wlp2s0 down
3) #sudo ifconfig wlp2s0 up
and so,....
4) SIOCSIFFLAGS: Input / output error ==> There are many internet forums where it appears solved, but they do not work!

Sometimes the connection is working normally, and suddenly it disconnects and there is no way. I solve the problem by restarting the computer. Some data of my equipment are these:

PC: HP Pavilion dv6000
Architecture: 64 bits (Intel Core 2 Duo)
Network controller: Intel Corporation PRO / Wireless 3945ABG [Golan] Network Connection (rev 02)
Kernel modules: iwl3945

I have tried to install / uninstall / reinstall drivers, but the problem is not resolved.

I also uninstalled Network Manager and installed Wicd, but the team stayed in an infinite countdown cycle to log in and did not re-enter.

Searching in Google are several alternatives to not have to restart the computer, such as entering hibernation mode, Connect to a hidden network or restart the processes related to Network Manager several times, but all are cosmetic and gimmicky solutions that do not go to the bottom of the question.

What I would like to know is if any of you knows a true fundamental solution to the problem. I understand that in all new versions of ubuntu that happens, and in 16.04 it is especially frequent, directly affecting our Linux Mint 18.

I'm desperate to have to restart the computer between 1 and 3 times every day. So much that I have considered the possibility of leaving Linux Mint 18 to return to Fedora and OpenSuse.

I appreciate your help.

sorry but this doesn't make much sense.
please show us the commands entered & their full output, in CODE tags.
if you believe this is related to something you found on the www, show us what. a link plus an explanation.

Hi, I can't say this will help anything, but it worked for a friend of mine.

first type into a terminal. it will say something like this:
Except XXXXXXXX will be replaced with a model number.

if that worked without errors, then type:

1. 2. 3. 4. 5. 6. (Where XXXXXXXX is your model number as explained above.)


Hope this helped, reply if anything goes wrong and i'll try to help.

I have Linux Mint as well, and I also had WiFi issues, but I thought it was a problem with WiFi router or Internet provider, so I changed both. Now it works perfectly

Have you tried connecting to a different router (perhaps a friendly neighbour would oblige) to see if that resolves the problem?

When you have the problem can you still see the various wifi networks or have they disappeared? I used to have problems of this sort with network manager and solved it by switching to wicd, but apparently that is not your problem. I also had problems once with a Broadcom chip card. I can't remember if the driver finally got updated or if I had to replace the card. I think I replaced the card. Check what card you have and what chips it uses and then see what problems others have had with that specific card/chip set.

perfect, I had the same problem and you have solved it for me in the forum, perfect. You would need to change the mac adress of the wifi device card. Do you know if there is an application that allows it, thanks
