Slow ADSL Connection

I have two network cards in my win 98 computer and when it starts up it hangs up for a minute at the win 98 logo and then it goes into windows. Also when i open up internet explorer and type in a web page it takes about a minute to come up with thepage. But if i still am in that browser and type in another web address it comes up in two seconds. If i open another internet browser then it takes about a minute to come up with the web page and then the rest is fast.
Does windows 98 have any problems with two network cards. I use one to transfer files to my laptop and the other for the high speed adsl.

Any thoughts would be appreciated.
