Lets see what the parameters are set to

Code: Select all

grep -R [[:alnum:]] /sys/module/iwl*/parameters
[/quote]

Here is the result of those commands:

/sys/module/iwlwifi/parameters/nvm_file:(null)
/sys/module/iwlwifi/parameters/swcrypto:0
/sys/module/iwlwifi/parameters/power_save:N
/sys/module/iwlwifi/parameters/led_mode:0
/sys/module/iwlwifi/parameters/amsdu_size_8K:0
/sys/module/iwlwifi/parameters/fw_restart:Y
/sys/module/iwlwifi/parameters/bt_coex_active:Y
/sys/module/iwlwifi/parameters/11n_disable:1
/sys/module/iwlwifi/parameters/antenna_coupling:0
/sys/module/iwlwifi/parameters/wd_disable:1
/sys/module/iwlwifi/parameters/power_level:0[/quote]

Code: Select all

sudo modprobe -rv iwlwifi

Code: Select all

sudo modprobe iwlwifi bt_coex_active=N
This might work[/quote]

That killed me.

I got stuck in an infinite loop of "connecting to wireless" then "disconnected"

My laptop was trying to reconnect to my same network it auto finds, but won't reconnect. I had to physically go plug in my laptop to write this. Dang!

Is there any way to reverse that for the moment while you still rack your brain?

At least I'm glad it's not just me having issues! LOL!

Wow, didn't expect that. A reboot will work or

Code: Select all

sudo modprobe -rv iwlwifi

Code: Select all

sudo modprobe iwlwifi]

On my atheros card, I get the opposite happening, it prefers that disabled

Ok, here is what I did:

1. I didn't remove your tweaks, yet

2. I reset my router to the default configuration

3. I set a static channel that was different than the one it likes to use automatically, which is usually 6. The prompt that it gave me was "doing this may hinder your optimal performance" or some kind of thing. I accepted the static change anyway. I kept it plugged in and the "wired" speed didn't change after the change, but the wireless speed dropped dramatically even sitting 4 inches away from the router! It was a change from the wired speed of 86mb down to 20mbs down. Before this whole debacle, it was about 50 down while sitting next to it and downstairs about 30. Odd how the 20mbs next to it stayed the same from upstairs to downstairs, even being that far away.

4. I'm going to download the biggest torrents I can find, or just multiple Mint distributions and see if I can encounter another disconnect.

While I'm doing that, do you happen to know offhand why the changes in speed of the wireless and no correlation between distance (including a ceiling and multiple walls) this time? It's weird.

In auto, the router likely searches for a channel with the least amount of noise or receiver signal strength which in most cases should be the best as far as data transmission rate is concerned. I will look at the LM kernel update when I get home to see if there is something that looks like it might fix the disconnects

Just FYI while looking at it.

1. I had the problems with the fresh installs we did with the stock 3.13 kernel that installs (no luck)
2. With the stock kernel, all the updates were installed (no luck)
3. I tried 3.15.0 (no luck)
4. I'm currently am on 3.15.2 praying that those released kernels would do something. (no luck)
5. I did all of your suggestions with the stock kernel before trying anything else.

I just wanted to give you all the information. :D

And just an update. After all of that work I just did, I stress tested my big file downloading, and it disconnected after about an hour. :x

Just did those. Is that all I need to do? It all seemed to install fine.

I rebooted too. Now I'm trying to download a large file. Going well so far.

Thanks to all of you for the help. I absolutely adore Linux Mint. I switched from Ubuntu to LM Maya and used that until the newest LTR came out. It's fantastic. Thanks for making this community work.

I don't have a newer release. The last release was in 2011.

Back to picking your brain, Jeremy!

Code: Select all

ls /lib/firmware/intel
And go into network settings, to the right of where your router is listed, there should be an arrow, clicking on the arrow should get you to another screen where you can click settings to edi t the connection. Choose the IPv6 and select ignore for IPv6, save

Here is the output of that command:

ibt-hw-37.7.10-fw-1.0.2.3.d.bseq ibt-hw-37.7.bseq
ibt-hw-37.7.10-fw-1.80.1.2d.d.bseq ibt-hw-37.8.10-fw-1.10.2.27.d.bseq
ibt-hw-37.7.10-fw-1.80.2.3.d.bseq ibt-hw-37.8.bseq


I followed your instructions and will reboot. I'll start testing again.

1. What did that command you wanted do?
2. Will not using IPv6 hinder any performance? Not sure what it is other than being a newer standard over v4

I just wanted to see if the firmware files were there even if I think they are only for bluetooth. IPv6 can cause some issues

You might want to try a new router also as I have seen issues with older routers

About the only thing I haven't had you try is

Code: Select all

sudo modprobe -rv iwlwifi

Code: Select all

sudo modprobe iwlwifi swcrypto=1
You haven't installed any kind of power management programs?

*Sigh*

It worked for about an hour of stress testing, then no joy.

I do have TLP installed, but I think the network card has no power management enabled. Tell me what you think.

About the only thing I haven't had you try is

Code: Select all

sudo modprobe -rv iwlwifi

Code: Select all

sudo modprobe iwlwifi swcrypto=1
You haven't installed any kind of power management programs?
*Sigh*

It worked for about an hour of stress testing, then no joy.

I do have TLP installed, but I think the network card has no power management enabled. Tell me what you think.

It does look like there are separate settings for WLAN on bat compared to AC and power management is enabled on pcie and then there is this
/sys/bus/pci/devices/0000:0d:00.0/power/control = on (0x028000 Network controller)
I would bet this is the wireless card


I was thinking you said this was disabled, is there any sign of TLP in dmesg

Code: Select all

dmesg | grep -i tlp
I have the same wifi card in my Dell and couldn't get it to disconnect downloading from the internet

Forgive my ignorance, but what am I looking for when I use:

dmesg | grep -i tlp

All I get is a return to a prompt. I see no output.
