Ralink STA support

Mon Sep 17, 2007 2:14 pm

As you can all see on ralink's page there are linux drivers for station support.
It would be nice if MikroTik just adds the module into the kernel and we can setup stations with these cards. I have already tested b/g/draft 2.0 N cards on linux and it seems to work very well.
And yes it even works in vlan environment :)

So it remains just on Atheros and Prism...

Chipset like Ralink or Realtek are the best option in noisy enviroments, always based in our test.

Atheros is more flexible, thanks to their HAL capabilities.

Yes and these cards are not only stable but cheap.
I have several tests under linux /using the new wireless stack which ralink seems to support in there new version of drivers/ and links seem to be stable.
No disconnects for about 72 hours of uptime.
The only limitation is that ralink don't share their AP drivers ... just for stations which I think is a good option of you want to setup a single client or office.
I have looked in to the mikrotik rootfs/I admit/ and I've seen very promising things.
The new version 3 is already supporting AR5416 / draft N / but I think less know that.
So if I have AR5416 as an AP I can have Ralink 2860 as STA.

Maybe it's time to change that now.


http://www.ralink.com.tw/press-releases-detail.php?s=22
From the first single chip 802.1n chip solution for laptops, to the only router-on-a-chip with integrated media access controller, radio, CPU, and 5-port Ethernet switch, to the first 450Mbps 3x3 802.11n solution with Beamforming and industry leading performance for multi-media applications, Ralink has led in many areas of technical innovation considered crucial to driving the market towards the new 802.11n standard.

Further testimony to the preeminence of Ralink’s solutions is the prominent inclusion of Ralink devices in the Wi-Fi Alliance’s interoperability test bed. Ralink’s flagship RT3883 3x3 450 Mbps Access Point and Station solutions were selected for their unparalleled combination of performance, size, efficiency and power consumption as the benchmark leader for a range of single stream (150 Mbps), dual stream (300 Mbps), and three stream (450 Mbps) tests. Ralink’s 3x3 802.11n solution was also selected as the Wi-Fi CERTIFIED™ n “sniffer” device used to capture and analyze wireless network traffic, report statistics, and debug protocol implementations issues in products which do not pass Wi-Fi Alliance certification testing
Just to mention that the last ten years I have always used Atheros based equipments, until a few weeks ago when I purchased two Ralink RT3052 based wireless routers for $20 a piece. I never expected those cheap routers to be good at all, but they stunned me with their amazing performance. I got wire speed performance in every directions, and no CPU load at all.

After reading the specifications, I understand why they perform so well.

The RT3052 has an embedded 5(FE)+1(GE) port Ethernet switch and a 5-port 10/100. Besides the normal L2 switch function, it also embeds Ralink’s patent pending packet processing engine (PPE) to offload AP/Router packet forwarding tasks such as firewall, NAT, NAPT and layer 2 bridging from the MIPS CPU. It also features a high performance PDMA (packet DMA) which not only sorts and retrieves packets to and from the SDRAM but also supports CPU offloading packet functions such as IP/TCP/UDP checksum checking/generation, PPPoE session ID insertion and VLAN tag insertion.
