Internet Fluctuation

I have a weird roblem
I use a boradband to connect to the internet suse 10.3
but when i start my pc internet doesnt work sometimes it does sometimes it doesnt
if it doesnt i reboor the pc and then it works
sometimes nothing makes the internet work
but it is fine on XP
so what should i do?

Could just be XP keeping control of the network device.Do you shut-down from XP,then, start the p.c. & boot to SuSE ? or do you perform a reboot from XP then boot to SuSE ? If the former, it may be as i stated above,if the latter,it could be that the device isn't getting an IP quick enough, in which case you should either extend the network time-out or get the router to hand out the IP a bit quicker
