... make you wonder - what kind of reference OS/system Atheros uses?
AtherOS + Atherboard

JR

... and what about - framer policy=none?
i.e. if u want the polling only, anyone tried this? thanks.

address=10.10.10.2/31 network=10.10.10.2 broadcast=10.10.10.3 interface=ether3 actual-interface=ether3
Seems correct to me.

Just change the address to .2/32 and network/brdcast to .3 manually.
ip ro pr = .3

All that's needed is a route to the other side!

JR

2 x 20MHz channels for PtP,
6 x 10MHz channels for PtMP, as you only want <=2mbps.
Plan your cells carefully and beware of ghost frequencies when using 5/10MHz.

Routed is best!
You may even tunnel the client into the core.
Use OSPF for failover/loadbalance on the PtP.

JR

Did you try setting update-stats-interval?

JR

I like the fact there is almost no power loss @36Mbps...

Don't forget the specs states a +/-2db, the power also varies across the band.

JR

Is this happening for PtMP only?

JR

Did this happen before 3.10?

Could be interference such as a microwave used at lunchtime.

Hi Geroge, I have set the packet size under the MTU, on General tab. As it is the AP that is most effected, doing it on the client side (ap rx) seems to help the most, but I have played with both directions at various times. I have also had some success with running nstreme with no framing and 1500...

JR

... 5GHz also has higher (coax) cable loss, something to keep in mind.

JR

-30 is a bit of overload for receiver, try adjusting these as the AP will try to jump from 6 to 54Mb, locking down the data rates will also help.

JR

If you are going with long runs and low signal levels, LMR 600 or better and LDF5-50A are good choices.

LDF5-50A is TOO near the cut off frequency @ 5GHz!

JR

U need 2 cards for 2 sectors.

Possible IRQ conflict, i had a problem with a 3Com ISA and IBM PCI (intel chip) both with IRQ 10, only one card would be running. Look at PCI info.

JR

Remove any cards first.
maybe you can try booting from a CF, if ok then ask MT to move your lic over.

#2 would not work!
http://forum.mikrotik.com/viewtopic.php?f=3&t=16318
sorry.

JR

Don't know why you would want to limit connections, maybe you should limit speeds instead.

JR

For IPSec, you may specify 'ip ipsec peer' with address as 0.0.0.0 (if address is dynamic or you do not have information about it, secret (pre-shared-key) and use 'generate-policy=yes. It should work.

Did you try with peer's IP address?

JR

There's interface base routing in v3, not sure if this is what you're after.

So where are we in 2007 with RC5?

anyone tested the disable-csma as suggested above?

oh, any mini-pci adapter will work, see the RB11 @ routerboard.com
and if your PC supports bootable USB, then you may use a flash drive

JR

I have a R52 MiniPCI radio card, instead buying a routerboard, which Router Board 11 IA should I buy to use the radio mudule in my PC?

Yep! and you can do so for free with RouterOS within a limited time.
Take your time in the manual, welcome to a whole new roooting world.
Tik, Tik, Tik ....

JR

The fastest boards would be the RB333 with v3 only!
SR5 wireless cards would be good, but search the forum for more info.
And take your time.

JR

There was a post named "Nstreme Bad Performance" or similar, had lots of info.
I know it got kinda OT at times but still would be an interesting archive.
User marksx made some suggestions there.

Normis please UNHIDE this post, of course you could lock it.
Hope you got a tan.

JR

... so that suggest a move (not copy) lic (to hdd2) command is possible,
anyway thanks for the info, will certainly make a note of this.

JR

Does it happen with 5GHz too?
Thanks.

JR

Would you be so kind and share the details?
x86 or RB?
PtP or PtMP?
etc, etc.
Thanks.

JR

Has anyone test this on a RB333 AP?
Thanks.

JR

I has similar problems before, pppoe client will even get disconnected randomly.

You may set ether speed to 10Mbps also.

Now all ether1 are POE, why not use a switch so u get to use a /24.
With daisy chaining you may have to set ARP to use a /24 or use subnetted ptp links.

These are really to do with the (rf) modulations, the rates in MT is really = to the various modes,

JR

Not to messup the post, but a tunnel can solve this.

JR

NO!
It's not a regular "bridge", its a tunnel.
It will bridge your IP net so you may use PPPoE, i.e. you will have two ethernet endpoints terminated into your PPPoE client and server.

Take a look at the diagrams in the manual for other tunnels, the networks are still ROUTED!

Your SAT provider should be able to help.

Create a tunnel (via FO) to SAT provider, this will be for upstream, OR get an IP from SAT provider and use it as your source (out interface) IP (so the only route back will be via SAT DVB).
