Windows 98 Computer DSL no internet browsing

a strange problem in the voodo world of networking
user had a windows 98 se p2 with a pci ( non integrated) network card
network card drivers are installed fine - standard intel /compaq pci network card
on dsl as a single computer
continual drops of connection
A router was added
Its a dsl connection
The router connects to the dsl connection fine
A windows 2000 computer works fine on the wireless connection
The windows 98 computer is connected to the router which is logged on
I have left the dns automatic , i entered the 2 dns of the isp
in the router
I have tried turning on the dns in the networking of the windows 98 computer and turned it off
No idea why it will not browse to the internet ( it seems connected but cannot browse) The router is logged on
The dsl software from the isp is still installed
Could that be the conflict ?
Any ideas ?
I took out the tc/ip and reinstalled to no avail
