Windows 7: Yellow triangle in taskbar network icon

i have 2 computers, one runs with xp and another runs with windows 7, the windows 7 is in my laptop and xp is in my desktop computer, i have adsl broadband connection, when i connect internet through wifi in my laptop the red triangle always shows, i don't really know how to remove that triangle,
but internet works perfect..
i changed ip address and dns in these two computers, it didn't work..
what am i going to do to remove this...

Well it could be a number of things did you try to trouble shoot your problem?

yes, i troubleshooted but didn't see any changes...
sry for late reply...
had some work...
is there any ip address configuration needed or not for two or more computer networking...

my ip configuration

Check in System that both machines are assigned the same workgroup name, XP default is MSHOME, 7,8 is Workgroup, change them both to something the same, then set network as Home or Private.

i already changed that name as workgroup in both computers and all network sharing is perfectly working... my only problem is yellow triangle in that network icon...
how can i remove it...???

It may help to change from a public network to a work or home network, the link below shows you how.
Network Location - Set as Home, Work, or Public Network

Also if you have an Ethernet cable plugged into the laptop it may help to unplug it.

Thats not solve this problem... i using lap only wifi connection, not to plug any ethernet cable in that... but my another desktop computer using ethernet cable to connect network...

any other better idea...

It may help if you can post a screen shot of the ipconfig/all, not just the ipconfig. Something installed on your system is causing this problem.

It's not a typical Windows problem at all.

here it is.. all ip configuration...
