You should access he Belkin an check to see if the DCHP or WAN access
has been turn on. Two DHCPs or two routing services can cause
problems.

I kept checking this.. thinking it was the belkin (dhcp was off).. but
as it turns out so far.. it was one port on the switch.. traced it
back to a workstation.. i went down to the users office to determine
what could be the cause.. after i get in there, the issue had stopped
and has since been ok.. very odd.. they have a laptop and a
workstation which they were flipping the same ethernet cable between
every now and then.

Still at a loss as to what was causing the issue.

I also have a Sonicwall serving N1 AP's. We've been having issues
with our Sonicwall 1260Pro and N1 AP architecture, and I've come to
the conclusion that it may have to do with DHCP forwarding on the
N1's. Wired connections work fine, and while in AP mode, the Belkins
work ok for a while, but eventually nodes begin to not receive IP
addresses; they get self-assigned 169.x.x.x instead. I've spoken with
Belkin a few times about this, and so far the best solution they gave
me was to place the ethernet cable from the Sonicwall into Port 1-4,
and not the WAN port. Again, it worked for a while then petered out
again.

I gave up for now; I currently replaced the old configuration with 2
Linksys APs running DDWRT and a Smoothwall firewall appliance in place
of the Sonicwall. Unless I find a solution soon, I'm putting the
1260Pro on ebay, and I'm going to probably wind up giving the N1's
away, or selling them for dirt cheap. They work great for in-home
wireless routers, but not so well on a larger medium-business scale
where you wish to keep all devices and nodes on a certain subnet,
without an extra routing hop and unnecessary network segmentation.
Unless Belkin comes out with an updated firmware that fixes these
issues (which I'm not personally holding my breath), it looks like we
may very well be out-of-luck for the time being. If anyone has
discovered a solution or even a work-around to the N1 as an AP issue,
please let me know. Likewise, if you're interested in purchasing a
Sonicwall1260Pro or some Belkin N1's, hit me up for a sweet deal! ;-)

It should be stated that some Access Points can have the wireless
network set up as a separate network that the regular wired network.
