D-Link DIR-655 :: Can Connect To Router But No Internet Connection

I recently purchased a new Dlink DIR-655 router. My motivation was a router with a USB port. I initially purchased a DIR-632. I have 1 desktop without a wireless card so it connects to router thru ethernet cable. I have 2 personal laptops with wireless cards and 1 work computer also with wireless card. With the DIR-632 all computers would connect to router, but my work computer (Dell) would connect but then intermittenly show no internet connection. All other computers had no issues connecting to internet ( wired and wireless) The Dell would connect and have internet connection if I used a wired connection. After talking to DLink Tech support they said that i had an issue with the Dell. I called Dell and they walked me thru several things. Nothing worked. They ultimately sent in a tech who replaced wireless adapter and did a diagnosis before leaving and the Dell was deemed to be in perfect working order. I tried connecting again after Dell's repairs and same issue. DlinK Tech support then said the issue was with router and suggested replacing router. Went back to place of purchase and obtained the DIR-655. Got home and exactly the same issue. Again on the horn with Tech support and issue was determined to be bad router. Went back to place of purchase and got another DIR-655. Got home tried new router same issue. Spent in excess of 4 hrs on the phone with level 3 tech support. We tried many, many possible fixes and it appeared as if we had the problem fixed, but within a hour of hanging up with tech support the issue was unchanged.

As the Dell is a work computer I use it a multiple locations, some with no issues connecting wirelessly and one location the same issue as at my home (interestingly enough this location uses a DIR-655). At this 1 work location it says I'm connected, it says there is internet access, but I cannot do anything on the internet.(I can connect without issue with an ethernet connection)  At my home location I can connect to the DIR-655 wirelessly, it initially shows internet access and I might be able to access a single webpage, but then it states no internet connection, but it is still connected to the DIR-655.

My initial DIR-615 and the Dell works perfectly fine. However that defeats the purpose of me buying the DIR-655. Ideally I want only the DIR-655 with all computers connecting thru it.

The ISP is a satellite connection. The modem is a Hughes HN9000. By spending 4 hours online with tech support we have changed the channel used, specified specific DNS locations, IP addresses, renewed DHCP, you name we have probably tried it.

The Dell for some reason just does not like the DIR-655, as it connects to the DIR-615 and 1 other work location router, but it will not connect at my home or other work locations (both DIR-655 routers).
