Thank you for your responses! I have now visited the customer's location and this is absolutly insane. Here is what I know.
The router is a WRK54G v2 with latest firmware (according to linksys) of 1.00.1
They are connecting through an MLS website at
http://maxebrdi.fnismls.com/Paragon. The login works fine, and most browsing works fine until they try to pull down this particluar saved listing. It should take about 15-20 seconds to pull this listing down when successful ... but during a failure it is just a white page, three to five green dots on the IE progress bar. Customer has waited up to 20 minutes and it never does anything.
When connected through the router wirelessly using WEP this particluar download described above works just fine. I know that they are using the local router by checking the DHCP lease on the router vs the IP address & MAC on the wireless NIC.
When wired thorugh the router - sure enough, it fails. I did some network traces during the failure to see where it is getting torn down. It appears the client is doing a FIN, ACK to the server after getting some payload about the page being unavailable, then it does a RST, ACK and eventually a RST.
I did come up with a work around temporarily though. When wired through the router I have them VPN into my home office (Microsoft VPN). Now the client machine is encrypting the traffic through the router and the page works just fine. As long as I can hide the payload from the router it works just great.
Furthermore, when they take their computer off-site and put it on another individuals network (wired) it all works fine. Everything is pointing to this router.
Here is the part of the network trace where it appears to get torn down:

Obviously, the easy solution is to find an older router (WRT54G) and replace the router at a cost of $49. But I am really stumped here ... and I look like a chump because I sold them the WRK54G router.
Is there a way to get this information to a Linksys Engineer to find out what is going on?
