@lifehacksback , I will save you.

The problem is Windows 10 and the Intel Driver. For some reason the latest Creators Update has messed up how the WiFi driver is used.

Please do the following:

Specific to your instructions, "the default driver that comes with with windows 10" would be the latest vendor WHQL driver at the time of the OS build (i.e. when the build was compiled by Microsoft).

Sorry, I was at work and didnt have the post saved, and didnt recall full details of what i did to solve this problem. Now that im home I can provide more information.

It as to do with v18 of intel's drivers. Downgrade to v17.

This solution worked for me. Please note that v18 of intel's drivers did not give me problems on windows 10 until i updated to the creators update.

@grunt Did you by chance try any of the other suggestions made by @Jacob W. Klein in the Microsoft Answers thread? 

  • I only ask because reverting a major driver update should always be the last resort, unless one is fully aware of the change log of the new version (as there's no way to know what bugs and/or exploits one may be opening themselves up to by downgrading).

I understand the security concern you bring up.

@Jacob W. Klein posted 3 workarounds. The only workarounds i tried was #1 and #3, with #3 working for me.

@PeggiDouglass posted in that thread on 7/24 that disabling tcp autotuninglevel worked for him. Might be worth a try.

Re: Update on Linksys WRT1900AC support

@grunt

Thanks for the input. I'm currently using v18 with windows 10 CU  which does have this problem. I would like to mention I have not installed anything "directly" from intel yet (Pro whatever they call it) and have just been rolling with window's update whql driver for intel wireless card. I'll try the first suggested way by installing the pro tools and using his provided profile. If that fails ill roll back to v17 since this would be the saner path (security bugs prob got fixed btw major updates)

Re: Update on Linksys WRT1900AC support

When I have time over the weekend, I'll also add an annotation to the Wiki page with the information @grunt provided, as that should make it easier for others using Intel AC cards to determine if they're affected. 

  • I only had time to briefly skim the first page of that answers thread... does this also affect Intel N wireless cards, or just AC cards?

Re: Update on Linksys WRT1900AC support

@jw0914,

It only affects wireless cards with have RSC (receive side coalescing) capabilities enabled in the driver.
I guess the reason the older 17.15.0.5 drivers works fine is due the lack of RSC, which was probably added in the 18.x drivers.
I can confirm the 17.15.0.5 driver is working properly, where all 18.x drivers failed and hung the wireless connection.

@jw0914

I'm going to go ahead and agree with this conclusion.  The wireless card I was having issues with is the Intel Wireless N 7265 card (single band).


Here is another website blog post illustrating the same 3 methods to try to fix the issue. It provides more visuals which may aid users as well:

Yes, the next release by the LEDE team will be named OpenWRT, the existing OpenWRT codebase is going to be archived (everything useful can be cherry-picked from there to the LEDE codebase, which will be named OpenWRT

Re: Update on Linksys WRT1900AC support

Just an FYI in case my post caused confusion...

  • Only builds based upon the current OpenWrt code base have been demoted... they are still listed under Firmware Images, however a warning has been placed above and next to them that they are "No Longer Actively Maintained"

    • The reason for this is two fold:

      • The OpenWrt repo has not seen a commit in almost a year, and therefor it is not acceptable to promote it's usage

        • This by default makes OpenWrt based builds unsafe to flash since no one has the time to comb over OpenWrt's GitHub to determine what exploits have, and have not, been addressed in the past year.

          • Chaos Calmer 15.05.1, for instance, was last updated March 15, 2016, whereas in contrast, LEDE Reboot 17.01.2 was updated June 11, 2017

  • The following builds fall under the demotion: OpenWrt Stable, OpenWrt Development, arokh's, & kaloz's

LEDE Branches have replaced OpenWrt Branches as the recommended code base to utilize

Re: Update on Linksys WRT1900AC support

kdriscoll76, Is it to be inferred from your post that you attribute the mamba reboot issue to excessive temperature of the device? If so, I have seen no indication of that to be the cause, also the start of the reboots seems to be clearly delineated to the use of the 4.9 kernel. The last build I tested(4.9.37) ran for 14+ days before a reboot.

I use a modified procd gufus fan script, supporting 3 settings (50%(default),75%,100%), checking temperature every 20 seconds. Only under extreme load have I seen it go to 75%, I have never seen it go to 100%. I experience reboots randomly on 4.9 (never saw this on 4.4), but have never noticed any correlation to a temperature spike and a reboot. If you want to see if that changes anything, 100% has got to suck if it is in within ear shot; the change to the governor might be intriguing.

Edit: vvvvv    Sure, the link is right above in the last statement   ^^^^

Edit2: if doing your own build and want it OOTB, add here:

        target/linux/mvebu/base-files/etc/init.d/fan_control
        target/linux/mvebu/base-files/sbin/fan_monitor

I'm not sure this is the right place to ask, but the 1900ACS v.2 has a port\carrier sensing issue while running this version of davidc: Lede Reboot SNAPSHOT r4542-0b493ed / LuCI Master (git-17.186.70712-4f127c3).

Re: Update on Linksys WRT1900AC support

I have an odd problem that popped up once I used useradd to add a user specifically for SSH sessions, however once I set it's password with passwd -a sha512 <user> (or -a sha256), that password is now able to be used to login to LuCI as root (i.e. both root's password and the new user's password can be used by root to login)

  • Even more odd, when the algorithm switch is used, all users with passwords set using that algorithm (incl. root) will show the same encrypted string in /etc/shadow

  • I have configured

    • /etc/group: <user>:x:1000:

    • /etc/passwd: <user>:x:1000:1000::/home/<user>:/bin/ash

    • /etc/sudoers: <user> ALL=(ALL) ALL

Re: Update on Linksys WRT1900AC support

I've been waiting for something official to come out and still running 15.05.1 on a 1900ACS, and since I've added a few more devices to the wifi, reboots are happening daily again. So I'm looking at doing an upgrade with LEDE which I hoped to never have to move to or support. But it's been awhile w/o any openwrt updates.

I looked at the wiki and didn't see anything from OpenWRT to LEDE in the "Flashing Firmware" section. Are we supposed to load the Linksys stuff and then add  LEDE or what's the recommended procedure?

OpenWrt's been dead quite a long time and is alive in name only... LEDE is current and is what should be utilized both in the build environment or as pre-compiled images.  This is why I downgraded all OpenWrt builds in the wiki.

As to OpenWrt to LEDE, there's no section since it's the same ways one would upgrade to a newer version of OpenWrt: LuCI - Update Firmware, sysupgrade, or serial.  LEDE is a fork of OpenWrt (when they forked is in the wiki), and since the fork, continuous development has been maintained.

Thanks for the reply. If I may ask, I can't recall if I have a v1 or v2 1900ac and didn't see anything on the wiki. Are there any markings on the unit (packaging unavailable) to tell? Also, does the 3200 have working drivers?

Update:
Found the versioning elsewhere, serials w/ 13J1 are v1, 13J2 are v2. But would still like to know about the 3200. Thanks.
