From Modem to Router

[newbee2]

Been away in Nightmare land configuring new wireless router to work with Limewire,read most of the tips,especially Lotr posts on setting up,after much frustration,tearing hair and eating innocent worksurfaces etc..finally it's working,clear globe etc... only thing Iv'e noticed is less ability to 'Browse' hosts and I still can't browse myself? as I used too. any ideas out there? why should my browse function be affected when nearly everything else is EVENTUALLY working?Other thing,windows Firewall is turning itself off after re-boot? I have got rid of Zone Alarm as not nec.(I never used windows firewall when I had ZAlarm) If Windows Firewall disabled, I have a sneaky feeling it's still operating !
Do I need it anyway? As I say when I enable it, it turns off when rebooted.Last point, are u any more 'exposed' as an ultrapeer? as u are 'behind' no one,Iv'e noticed most ultrapeers only have very small 'innocuous' files being shared??Is there a reason for this?
Any other people considering router route now have my deepest sympathy,GOOD LUCK !!
PS Should have said,people can upload and I can download, just cant browse.Only very occasionally
PPS Sorry if this is posted in wrong place ?HELP PLEASE !!
PPPS I have 'chat' enabled,was able to browse before changing to router,now almost impossible,will i just have to live with crippled lime wire? I read that browse is ''luck'' but it WAS working,,AAAARRRGGGHHH !!!!
