Re: v6.21.1 released

Actually MT should only allow new releases with permanent version number ready in their download (for auto upgrade) section when they are approved by many clients and at least are around for a month or so. Any other version, no matter how good they think it is, should be not considered to be 'defin...

Dear Deac....
in fact, i really have no ideal about this...

if you don't mind, you can tell me more which i will learn from it...
Just trust me.
In case of two sequentially connected 6.8Ah accumulators you will have at least 14 hours.

Re: Wireless bonding technique.

Nope.
'Round-Robin' doesn't work with asymmetrical links because it breaks the packets order.

Re: Wireless bonding technique.

Wrong way.
'Balance Round-Robin' works ONLY with links who have same throughput.

If you have asymmetric links then you need other balance mechanism.
Like 'alb' or 'tlb'.

Re: Wireless bonding technique.

UBNT XR5 isn't 802.11n card and has only one chain.
I guess you're replacing 'band=5ghz-onlyn' with 'band=5ghz-a' in this config?
If yes then try 'nstreme' or '802.11' wireless protocol instead 'nv2'.

Re: Wireless bonding technique.

In this scheme bonding works through VLAN iface instead of HW iface.
P.S. This technique is inapplicable for ROS v6.x series. Coz bonding still broken.

Small question.

I have a middle-range NV2 link and it work fine for me.
But I see a very strange client state:

Re: R5SHPn

R5SHPn is a very specific equipment.
It has only one chain and very high power.
One chain limits rate to a 150Mbps and high power can be superfluous for the short-range CPE.
As a result: R5SHpn isn't best choice for creation of WiFi sector.
Try R52nM or R52Hn if you need more power.

Re: Problem with 2 SXT's and Ptp Bridge

Try to use WDS.

At first retune on the STA side:
-- Mode: 'station wds'

At next retune on the AP side:
-- remove wireless card from the bridge
-- WDS mode: 'dynamic'
-- WDS default bridge: '<your preferred bridge>'

It's works fine for me.

Wireless bonding technique.

Would not write in the future, this is understandable. But how to avoid spoiling the current config by the suddenly appeared bad blocks? I don't know how MT stores the current config, but it's worth having in the two copies.
