problems with link between 2 bridges

[nino]

Hi guys,

I have problems with a link between 2 bridges Cisco 350 series.
The scenario is very simple:

Internet----bridge--( )---bridge---Switchwithclients

The link have 10 km of distance and the problem is :

- Interruption the navigation of clients
- I am verify using pings extended and someones go well and others not.

If I connect the bridges in the bank test (nearly) the problem is not present.

There is some parameters to set for example:

-spacing bridge (Km) (default value =0)
-Frag. treshold (default value =2338)
-Max. RTS retries (default value =32)
-RTS treshold (default value =2339)
-Max data retries (default value =32)
-Beacon period (default value =100)
-Data beacon rate (default value =2)

I set the first value to 10 and equaly dont work

Are there something specific value for this fields I must be set for that link works corretly?

I appreciate your suggestions

Thanks and regards
Nino
