Broadband DSL is accessible by some PCs however not by other PCs.

Am experiencing an odd problem at home (Auckland, New Zealand) with getting internet access from two laptops (taken from the office) which I have struggled to resolve.
Existing set-up at home is a D-Link DSL-500 ADSL router with the RJ11 port connected to the DSL line, and the RJ45 port is connected to a Linksys WRT54GL wireless access point/router which has 4 x RJ45 ports and one RJ45 port for the DSL Router connection. A home desktop PC (Win XP Home SP2) connects directly to one of the 4 x Linksys RJ45 ports. A Toshiba laptop (Win XP Pro SP2) connects wirelessly to the Linksys. Routers are set-up as DHCP, Linksys with WPA TKIP and with MAC filtering turned on and SSID broadcast turned off.
At the office I have a Mac PowerBook G4 (Tiger) and a Compaq/HP tc1100 Tablet (Win XP Tablet Edition). Both of these devices at the office connect to our office network either wirelessly (using a similar Linksys) or via an Ethernet connection so I know that these two devices do function normally by either connection method. Both are set-up to take whatever IP address is given to them by the office network/routers.
Problem I have is that neither the Mac PowerBook or the Compaq Tablet can connect to the internet DSL connection at home via wireless (Linksys) or Ethernet (RJ45 cable to Linksys or RJ cable direct to Dlink). Both used to be able to connect to the internet via wireless at the very least. I have not made any config changes to either the Linksys or the Dlink at home.
I have tried using both IE and Firefox browsers on the Tablet and Safari/Firefox on the Mac. Both Mac and Tablet devices will connect to the Linksys via wireless and I can admin (using a browser) both the Linksys and the Dlink over the wireless or connected directly to the Ethernet port on the laptops so the office laptops can see home Dlink/Linksys. However, I still cannot get an internet connection. Home desktop PC and Toshiba laptop continue to work fine of course.
Even if I run an RJ45 cable directly from the back of the Dlink ADSL router to the Ethernet port on either office laptop I still find that neither of these laptops can onnect to the web. I can still admin the Dlink router though. I have tried clearing cache, disabling firewalls, disabling antivirus, renew/release ip in DOS (on the Tablet) etc.
I have powered off/on both the Linksys and the Dlink. I have tested whether a direct connection to the Dlink should work using the home desktop PC and confirmed that a connection to the web is possible via this method (just not with the Mac or the Tablet).
I am frustrated that the office Mac and Tablet work fine at the office using either wireless or ethernet, the home desktop PC and home Toshiba laptop work fine at home with the wireless or ethernet so there is no obvious problem with either set of equipment however the Mac and Compaq tablet cannet get a web connection at home. Is there some setting I have missed that I need to check or clear? Some kind of IP conflict that is not being resolved??
Would be happy to get either the Tablet or the Mac working at home if one is more straightforward than the other to resolve....
Thanks in advance.
