Re: [OpenWrt-Devel] [Cerowrt-devel] [RFC PATCH] packages: Smart Queue Management for AQM Packet Scheduling and Qos from CeroWrt
Sebastian , Dave, Thanks for these instructions. I just finished a round of 3 months testing this setup on a couple of MyNet N750 ( AR71xx based ) in several locations. The feedback from users is very positive and encouraging - Most of them say that they feel the networks behave a lot snappier than before [ 7.5Mbps Up/ 1Mbps Down]. All I had to do was install the 3 packages over BB 14.07 : ip-full from the OpenWRT BB repository and luci-app-sqm + sam-scripts from the CeroWRT repository. Will the later two packages ever make it to the main OpenWRT package list? or there other packages that on the main OpenWRT distribution that can be used to provide this functionality?

[OpenWrt-Devel] Regarding USB and the Dlink DIR-600 Bx
Good evening, I just tried the BB RC2 build for this router and it seems the image is much larger than the one for AA. Checking the installed kernel modules I found the kmod-usb-core and an other related module. Is it possible to eliminate these modules for this router ( and probably for the DIR-300 Bx ) since enabling the USB support on them is near to imposible ( unless you can hack ball grid joints from the logic board). Since they're build using the ralink generic target - would I need to create a separate router file for these devices in order to avoid ruining other working devices that do nees USB support? The resulting image without USB support is 0.7 MB smaller and allow other ( more useful or better suited) packages to be installed.

Constantine, The JP1 headers are present on the N900 just as they are on the N750. I'll put a copy of the boot output on the console next week. The original firmware for these devices seems to be linux based ( the GPL code from the manufacturer ).

This firesale appears to come and go since late 2013, even before the whole line was discontinued in early 2014 (for example, Staples still appears to have some N750 left, but it's not on sale this week, unlike N900). http://wiki.openwrt.org/toh/wd/n900 http://www.staples.com/WD-My-Net-N900-HD-Dual-Band-Router/product_937135 However, N900 it's not supported by OpenWRT -- the whole Ubicom IP8K platform is not supported.

Re: [OpenWrt-Devel] Any plans to support WD My Net N900 (Ubicom IP8K 600MHz, 8x GigE, 256MB)?
Constantine, I'm looking into porting OpenWRT to the WD MyNet N900. Since the IP8K has an mmu it should be able to compile without too much issues. I'm currently trying to get the toolchain from trunk to work. Regards, Luis E.

[OpenWrt-Devel] Porting OpenWRT to Ubicom32 for the IP8K
I've done some research about OpenWRT and saw that thew Ubicom32 targets were removed a while back. It was my understanding that IP5K and IP7K didn't have a Memory Management Unit (MMU) and that caused this architecture to be not very maintainable. The IP8K does have a MMU and in that sense it would behave much like other processors used for other OpenWRT supported devices - fork() shouldn't be an issue since now we could do context switching and the main quirkiness would be how to manage the threading. In this case - what would be a good way for me to start trying to Add support for this processor to the Cross-Compilation configurations. I'm willing to maintain this target, but I need some guidance to help me get started. From the GPL code for the MyNet N900 I can see that the latest version they have for the Kernel is 2.6.36 - Is this a good starting point? or should I try to get a newer version Kernel to compile. The GPL code with the BootStrap published by Western Digital compiles cleanly and generates a working image - I was able to modify it and plug a DNS Leak on their implementation.

Re: [OpenWrt-Devel] Found the issue with the N750
Felix, The GPIOs in trunk are working correctly - they behave like the Original Firmware. When the Radio 0 (2.4GHz) is enabled the GPIOs for the LNA0 and LNA1 are set to HIGH and when the driver for the Radio 0 is disabled the GPIO's are set to LOW. The command: cat /sys/kernel/debug/gpio was very useful. For Radio1 (5 GHz) what is the way to test if the LNAs for that radio are enabled/disabled?? Luis On Wed, Feb 12, 2014 at 10:13 PM, Luis E.

Steve, Chirag, I'll be testing the signal strength on both bands this week ( I don't want to rush any results, while we wait for Gabor's answer). For the test I'll use 3 firmware images: - original WD N750 firmware (latest version). - r39542 with patch. - r39542 without patch. I'll take note of the signal strength in dB (RSI) and also do a short speedtest on a file transfer.

Re: [OpenWrt-Devel] MyNET N750 - Actually turn the LNA on.
Chirag, Can you test the reception on the radios with the patch at r39213. Also can you check the behavior of LuCI with revision on the r394xx range. I get better reception on the 5GHz radio and a resposive LuCI [Configuration of radios WLan0 WLan1] with the changes made on patch r39213. Builds with revisons r39217 or later introduce lag on LuCI [Configuration of radios WLan0 WLan1] and the radio reception on the 5GHz is much lower in my tests. If you can point me in the right direction to check the state of the GPIOs from the console on the router I can test the images and see the status, and post back the results.
