Thank you for your message. Firstly, the revision number of your router is very important to know. Only revision numbers 1.0, 2.0, 2.2, 3.0, 3.1, 4.0 are supported from Linksys wrt54g. The LinkSys Wrt54G is a very old router, and our system doesn’t work on all the versions of this series of routers. From Linksys we always recommend the Linksys WRT54GL that is still available in the market.
