Can you ping the computers from the routers?

I tried pinging the PC's from the router and all was successful; 0%

It's a D-Link router running DD-WRT, so I guess you can call it a
switch. Both of my SUSE wired PC's are connected directly to it. I'm
confident that hypothetically, if each PC was connected via wired
ethernet to an individual DD-WRT client bridge router (1 client bridge
router per PC) there would be no problem with those 2 PC's talking
with each other, pinging, sharing files, etc. But here there's a
situation where 2 wired ethernet computers are both connected to the
switch, and then that traffic is routed to the master router via
wireless link and back via wireless, and then routed out through the
wired ports. I think it has something to do with the routing table and
modifying the advanced routing table in the client bridge router to do
what I'm trying to do, but that is just a guess.
I'm running dd-wrt v3.0-r29519 on a Linksys WRT54G and also a Linksys
E1200 one is a bridge the other an AP, both work fine either via
wireless and multiple pc's connected to the bridge in 'repeater' not

On advanced routing the Operating Mode is Router and the Dynamic
Routing is set to LAN & WAN.
