[mdlug] Hopefully Easy Network Problem

Peter,
    It sounds like you have a switching loop going on.  Make sure that
the Dhcp server is only running on your main router not on the access
points. I would think that maybe plugging the switch and access points
in a different order may fix your problem.

Good Morning All,
	I wanted to set up to wireless AP's with different levels of encryption
on the same DSL line. I need the different encryption because I still
have older notebooks that don't support wpa. So what I did was to have
the phone line come into the modem, then to a SMC auto sensing GB
switch, then out to a Linksys WRT310 GB router and a WRT54GL router.
Both routers run dd-wrt firmware, the 310 set up for wpa encryption and
the 54 for wep. Plugged into the 310 is the ethernet wiring for two
stations in the office and a Roku Netflix player. Everything is fine
until I plug the WRT54GL router into the switch. Then my internet
traffic slows to a crawl, both wired and wifi on the WRT310. I've
checked the phone line and taken out an extra lightning arrestor at the
demarcation point. There is another in the newer network interface
outside the house and the line runs into a APC battery backup before
connecting to anything. Not thinking that has anything to do with my
problem but wanting to rule it out.I looked into bridging the slower
router to the 310, but I came up with this. I'm not sure how much detail
is needed so I left the details of the various speed tests out. I've
tried plugging in the routers and modem into various different ports on
the switch not really thinking it would do anything. It didn't. The
routers radio channels are set to one and ten. The routers are about ten
feet apart and the WRT310 is four feet above the other so far. The
WRT54GL does not appear to interfere with connecting to the wifi on the
WRT310 and vice versa. Hopefully I did something very stupid that's
easily fixable.

Best Regards,
