I am looking at utilizing a Mikrotik rb411 routerboard for a Upstream router. this router uses a atheros AR7130 300MHZ processor. It has 32mb DDR sDram Memory and 64mn onboard Nand memory. Boot loader is RouterBoot.

I think the throughput of this board would make a big difference on the overall speed of the Mesh. I have read many, many articles and forum posts that indicate one of the big slow downs of non backhauled mesh networks is the speed and capability of the Gateway router.

Anyone have thoughts about this?

Also, could anyone point me in the right direction on how to reflash one of these boards. I must confess that I have never flashed any boards before but have been in the computer industry for over 30 years. Help would be greatly appreciated.

Thanks,

Fred

Hi,

Was curious about some of your readings. I'm very interested in learning the external factors that affect performance.

Would you care to share any of your reading sources?

THX,

Having a stronger hardware is never a bad thing. Though the border router isn't the bottleneck of your mesh unless you have a really big network and/or a lot of users/connections. It would be the single radio, the shared media for up/down backhaul and access. Try to avoid more than 3 hops, deploy enough nodes. Also routing protocols (especially proactive ones) can generate big background traffic so mesh nodes may need decent resources to handle it. Batman the one used by robin is trying to avoid it and it's getting better.

It would be good to have a strong gateway system if you have a lot of users and are using a hub and spoke network. Because all of the bandwidth from the spokes would converge in that one spot.

I am looking at hub and spoke style networks and a lot of traffic to the hub. Does anyone know if it possible to flash a Antheros AR7130 router board with Robin ?

If not, how successful was the reflashing of the Ubiquity PS2. If this is feasable, (what I remember is that Antonio had a real struggle to get it to work because of the small flash size) then a Nanostation would be a second possibility but it only has 185MHz processor.

Most of the projects I have been asked to setup networks for require a gateway (upstream) router to centrally flood the area with a wireless signal then individual nodes to help spread the wireless cloud throughout the area.

Thanks,

Fred

I really like the Routerboards but it seems to me that a micro-ATX x86 box would be the best choice for a "head end" gateway node. The FitPC (

) that I mentioned in another thread a while ago looks to be the most promising unit I've come across so far. Dual NIC's, a 40GB HDD, and extremely low power requirements make it well suited for deployment in a wide range of applications.

Tate,

I like the Micro-ATX as well as the Via Mini and Pico atx. But I wasn't sure if ROBIN would ever be compatible with this architecture. I was trying to stay with atheros based boards. Also this new SOC 7100 series has 802.11N, usb Gigabit and several other very interesting features. Appears to be the direction that new Atheros SOC's will be going.
