Re: Downgrade 3.24 to 3.13

Dear Chapex, I have al my network with RB433AHs with 3.13 software, stable software tested by us. When we'll test a new software version I'll upgrade all my network. In my opinion it is not correct to have different software in the same network. Could you help in telling me if does it exist a RB wit...

Re: Downgrade 3.24 to 3.13

Dear all,
- RB411 is downgradable from 3.24 to 3.13;
- RB433AH is not downgradable from 3.24 to 3.13.

Does it exist a board with 3 miniPCI slots downgradable from 3.24 to 3.13 ?

Regards,
Alessio

Re: Downgrade 3.24 to 3.13

Normis, thanks. Technical explanation is clear now. The problem is that in production environment I don't want to install software not already fully tested. So, condering that my boards' load is quite low, if I use RB433 instead of RB433AH can I install 3.13 ? In other words, what AP-boards are full...

Re: Downgrade 3.24 to 3.13

Normis, so, just to be clear, the answer is there is a bug, but we won't solve it (or we cannot solve it)

And with your software you declare possible or not possible to make a downgrade? And if this is not worki...

Re: Downgrade 3.24 to 3.13

Dear all,
I think this should be considered a very big bug, of course not for a test environment, but for a production environment.

Is someone working on it ?
Can you give a solution or a workaround to solve it ?

Thanks,

802.11b limit - CSMA

Hi everyone, 802.11b has a really great limit because it works as a very old hub, with a speed of 11Mb/s for all the customers attached to a single AP. So, without any bandwidth limit, if you have 10 customers all goes ok, if your customers become 25-30 all speeds go down because of collisions becom...

Re: PCQ and global-in, global-out

Hello Faton, you can specify either just global-in, or just global-out or both. For global-in and for global-out you can specify different bandwith and, in general, different everything. So I think that the router use both queues if you specify both. And any packet is queued twice if you match it tw...

Re: RB133c Wireless CPE Auth problem

It was a hardware problem.
The CPE received a very good signal and than It tried to join the network, but the R52H card mounted on it wasn't working good and than the other side didn't receive anything.
So the authentication handshake went in timeout.
