I think one can only cascade unmanaged hubs/switches. The above topology was causing confusion within the switches, especially the wireless router (connected to all three switches) as to which port of the two ports to send the ethernet frame. I think only intelligent hub/switches can figure out paths for transmission, reserving the others for fail overs.
I think the OPs terminology is a bit confusing as well. Is he using switches? What kind of switches is he using? or is he using routers? again what kind? whats the model no? and why is he required to frequently reboot them?
Agree with your last question about rebooting the router - why?
As for the topology, I understood what the OP was trying to say. This is what I understood.
WAN | | ====== A (DSL router w/WLAN and 3 wired port switch)
========== B (8 wired port switch)
========== C (8 wired port switch)
========== D (8 port switch)
(1) A - is connected to B, C, and D (2) B - is connected to C and A as in (1) (3) C - is connected to D and A as in (1) (4) D - is connected to B and A as in (1)
The only thing that was not clear to me was whether he is using intelligent switches or vanilla unmanaged switches. From the little I read about ethernet topology, I don't think above is kosher and that is why things were not working.
B, C, and D cascaded with any _one_ of them connected to A is OK. That way when A is hosed at least the PCs on the LAN can communicate - which is what the OP finally did IIRC.
