Topic: Update on Linksys WRT1900AC support

The content of this topic has been archived between 16 Sep 2014 and 7 May 2018. Unfortunately there are posts – most likely complete pages – missing.

As always, precautionary measures should be taken when flashing new firmware, especially when we are talking about trunk images. ALWAYS flash from official Linksys image.

CC with btrfs and luci (16 MB): https://www.dropbox.com/s/srw98dtia826f … s.img?dl=0

New compiled images (01-02-2015)

CC with luci (9 MB): https://www.dropbox.com/s/2inon2pnhoa46 … s.img?dl=0

CC base (8.63M):  https://www.dropbox.com/s/srw98dtia826f … s.img?dl=0

If you compile CC from trunk use McWRT CC .config file and run "make -j# V=s" just be sure to not let your machine enter screen saver mode use something like caffeine plus (unity) or caffeine (gnome,xfce, mate, kde) so you avoid a failed compilation

hi kaloz,

i'm a new Linksys 1900 owner and i have flashed the latest openwrt image from this thread. (today)

i did some LAN speed tests also:

reading and writing a 20MB file to a LAN device with flash memory (no HDD) from my PC:

Write Time = 1.7821843 Seconds
Write Speed = 89.7774720 Mbps
Read Time = 2.1072027 Seconds
Read Speed = 75.9300480 Mbps

Sounds like the switch is set to 100mbit instead of 1000mbit ?

Anyway, its good enough for me to flash later today smile

Can i just flash this CC image from McWrt 1.0.8 ? and keep settings or start fresh ?

what is the output of "ethtool eth1"

Why is the package not installing?

@lifehackisback

I'd rather run make menuconfig before building an image than use a .config file from a different trunk.

Is this affecting the new image you posted?

@Kaloz

Cleanly unmounting an e-SATA drive puts the corresponding LED OFF. Great work, keep it up!

It's affecting all the images that weren't build with it hmm

Anyone know what are the "musts" settings for a successful build? or the minimum settings?


------------------------------------\

built new image with a fresh .config made within the trunk image but i haven't test it yet (5.6 MB) built with luci

Very useful:

Half duplex... that could be a problem wink

@kirkgbr

That's because the partner's advertised link mode is half wink

I finally had some time to experiment with my 1900AC again. I also saw the low LAN speed (relative to expected), but switching to the 3.18 kernel solved that. However, I am having large Wifi-problems. Parts is probably because I am missing some packets, there are some issues related to authentication, but I also have problems when connection to open wifis. The connection is established and works for a while, before it silently dies. Packets are sent, but no replies received. Does anyone else see this?

Also, I am running nginx on my device, but for some reason all the requests (both originating locally and from hosts connected to the LAN) gets corrupted somewhere after the packets are received from the network. Has anyone seen similar behavior? Every other networked application I have tired works fine.

Wow! How does one go about compiling a newer kernel onto openwrt? big_smile

The mvebu-target already has support for kernel 3.18. In order to switch to 3.18, you change the KERNEL_PATCHVER value in target/linux/mvebu/Makefile from 3.14 to 3.18 and compile a new image.

Oh, and I meant WAN-speed, not LAN-speed. But I guess you got that smile

Please dont use my images as they are missing support for hdd and might be missing other things... sad

use this instead: https://downloads.openwrt.org/snapshots … actory.img

then build up from there (since it comes with no Luci)

So I've tried all the different images etc.. NOTHING beats the speed I get out of McWRT AAv1.0.8(which I have re-flashed).

I can hardly wait for MCWRT Chaos Calmer(I love the interface!) with the new drivers. This router is on the brink of the stardom achieved by the WRT54G. When it does, it is thanks to Chadster and team.

With today trunk data transfer crashes when going to read or write files shared by samba(also with minidlna) in WRT1900AC , but only goes through wifi, ethernet works but is very slow, only 10MB / s. I tested with an NTFS disk and other EXT4 and with both is the same.
anyone know that can happen?
Thank You

I am running McWRT v 1.0.8, looks like i should stay there for know...

Samba is spotty on wifi, wifi is spotty as well odd since in my build wifi was working relatively stable hmm I just spent the last 2 hours digging through the menu and have enabled and disabled several features, since the .config from the "snapshot" took a very liberal approach and just "M" almost everything, yet their image is only 5 MB ?!? Building right now, hopefully wifi can be stabilized since i was loving CC hmm (of course overlooking the slow lan speeds). Might try again with Kernel 3.18 but im exhausted after many builds/test.

Agreed

@LookingForMyMojo

The web interface is available in McWRT repo too. Just install luci-theme-bootstrap then under System tab, Language and Style, choose Bootstrap instead of Openwrt.

kernel 3.18 fixes wan speed. ethtool eth1 shows Duplex: full, however it isnt as stable as Mcwrt 1.0.8 (i would get 180 steady while on 3.18 i get 176-7 and a bit jittery)

--------------------------------------------------------------------\

This is the best img I have of CC (https://www.dropbox.com/s/dzr9sj2meit2e … 9.img?dl=0) Wifi and wan are almost 100% operational big_smile

2 caveats:

- 1 compiled modules don't load for some reason (ex I compiled kmod-ata-marvell as a module and connected my hdd and nothing showed up hmm so im compiling with the modules included and loaded)

- 2 kmod-* dont want to install via opkg? they keep nagging about dependencies unmet yet when i use the snapshot img they install just fine or when i compile them they work hmm This is very confusing and frustrating

This is another image with built in hdd and full wan: https://www.dropbox.com/s/mhtpse4cadnp6 … y.img?dl=0
