Hi,
I am having issues with openwrt on the WRT3200ACM. Is there anyone who has this running? I have installed "rango". While the firmware loads fine, the wireless performance (speed) seems to be very poor and deteriorates very fast from a reboot. The normal linksys firmware works OK. Any help appreciated.
Thanks,
S
Which firmware do you use? Your own image or downloaded from somewhere? Also can you be a bit more explicit on "very poor"?
Hi,
Firmware downloaded from as the "Mildly Customized Chaos Calmer [CC] Build":
wiki.openwrt.org/toh/linksys/wrt1x00ac_series#tab__wrt3200acm
By very poor I mean that I only get about 15 Bits.s^-1 over the wireless connection and it deteriorates. Plugging an additional access point into the linksys router gives the full bandwidth of that access point.
I confirmed with the OEM firmware from linksys I get the full bandwidth over the wireless.
I suspect the wireless driver, but was looking to see how I can get an update.
This is the details of the wireless driver (kernel mod):
root@OpenWrt:~# opkg list | grep kmod-mwlwifi
kmod-mwlwifi - 3.18.23+10.3.0.16-20160105-1 - Marvell 88W8864 wireless driver
kmod-mwlwifi - 3.18.36+10.3.2.0-20161013-2
root@OpenWrt:~# opkg list_installed | grep kmod-mwlwifi
kmod-mwlwifi - 3.18.36+10.3.2.0-20161013-2Any help appreciated.
This is the latest wireless driver available. So nothing newer to try. The only report upstream for Rango is wrt VHT160. Also auto channel selection is generally known to not work.
At this point the best you can do is share your configuration and hunt trough the logs for anything suspicious. Maybe you can also single out a specific wireless client for causing the issue.
Thanks Sera, Will do. Can't be a client because I have tested with just one individually.
I am running the exact same build as stuwilkins and see that connections to the router are terminated about every 1 to 2 hours when streaming at about 10 Mbit/s. At the same time I see the following kernel log-message

[20884.723587] ---[ end trace 4da9480fc9556bfb ]---I see there have been driver updates since Kaloz made his image:
I can confirm that I see the same crashing, also 5GHz only works on channel 32 as per:
github.com/kaloz/mwlwifi/issues/111
Still having problems with radio crashing, anyone have an updated image or is it time to try to build one?
LEDE and owrt @sera patched 4.9-rc4 kernel images with latest mwlwifi. I doubt the latest mwlwifi will address, this but may be worth a try.
I brought the WRT3200ACM because I wanted a new router with customisable firmware. When do you guys think that I'll be able utilise the MU-MIMO and Tri-Stream 160 technologies that this router is born with, using OpenWrt? How long do you think it'll take before I can install it and still have a nice and stable router?
I'm new to custom router firmware, and that's why I don't have any idea of how long it'll take to develop this 
I have posted an issue on github for the wireless driver, hoping to link together the issues. I am happy to try to debug but have had to plug in my previous router as an AP to run the wireless and run the WRT wireless as a test. The github issue is here:
github.com/kaloz/mwlwifi/issues/118
P.S. Anyone know how to be able to post links (URLs?)
@stuwilkins
Ability to post links is available only after an user's post count reaches a certain number.
nitroshift
Lucky you for Marvell to be able to reproduce your issue, now it's just waiting for a fix.
Here the clickable link to the bug: https://github.com/kaloz/mwlwifi/issues/118
There appears to be another bug in the mwlwifi driver merely leading to the client being deauthenticated, which onlyrequires a reconnect in order get things going again. I haven't been able to figure out what triggers the bug. The backtrace is

[ 672.863892] ---[ end trace 258b7bf9460fc517 ]---Unrelated to the issues above, I have updated the device tree file to include definitions for the hardware crypto processor and future implementation of the Parser and Classifier driver. I will merge the changes some time this week.

Nitroshift, love your work as always.
Any interest in making the Bluetooth radio available through the DTS?
Also brainslayers comments (GitHub) that our current DTS misdefines several elements. Is this being looked at?
@Lantis
Bluetooth isn't used as such. An update to the dts will be merged these days.

LE: changes submitted.
@stuwilkins
The wireless driver is wrong. Rango uses 88W8964, *not* 88W8864 which is present in the WRT1x00AC series.

@nitroshift
Anything wrong with the dts changes? I just saw you deleted the branch on Github.
@wongsyrone
New branch available. I forgot to add wireless powertables.

LE:
Seems that powertables aren't needed at all as they are hardcoded in the chips. Reverted the change and submitted upstream.

I've noticed that the power and wireless leds don't work in the latest LEDE r2540-6f77b8d version.
@Chadster766
Have they worked before?
nitroshift
Only with the Linksys firmware.
@Chadster766
Thanks for reporting that. Will have a look at the device tree file and create a pull request to solve this.
