A problem just recently started on our family laptop (Dell Studio 1537) wireless that I have not encountered before.
I can access the home LAN via wireless (and the home PCs on the LAN can access the laptop via the laptop’s wireless (and our home router)) but the laptop can not access the Internet. Other (wired) PCs on the LAN can access the internet.
The wireless device is a:
04:00.0 Network controller: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection
Subsystem: Intel Corporation Device 1121
What has me puzzled is last time we used the laptop (my wife was using it) the wireless worked for internet access on our home LAN. This was around a week ago, just after the 2.6.27.37 kernel update. I installed the kernel update, confirmed wireless to the Internet worked, and then my wife tested the laptop, and we confirmed wireless to the Internet worked then. We have not changed any router settings (indeed we have not accessed the router’s configuration menus). So nothing has changed on our side of the ISP connection, and I can’t see the ISP changing something to cause this.
I note the laptop’s wired ethernet connection to our LAN does give Internet access.
Some aspects which may help explain the puzzle, we did have wicd installed. wicd (and ALL wireless, including LAN) stopped working after the 2.6.27.37 kernel update. So I went to yast (a week ago after the 2.6.27.37 kernel update) and configured for the tradtitional ifup (ignoring wicd). Wireless with Internet access worked then with that and survived a few reboots and functioned. I noted to myself to fix the wicd problem later. Today, Internet access with the wireless does not function. Today, AFTER discovering wireless access to the Internet did not work, I have subsequently removed wicd, although that makes no difference (I did not expect it would - I simply saw no point in keeping a non-functioning package).
So there is something specific to the wireless that is causing a problem for Internet access (although access to the LAN via the wireless works).
It suggests our router, but note our router has not been touched from before when it worked.
dell:/home/oldcpu # rpm -qa | grep kernel

The laptop’s desktop is KDE-4.3.2.
RPM’s installed (chronologically) since kernel update are:

hence I see nothing there that could cause problem, since laptop’s internet access via wireless worked much later Sunday afternoon (1 Nov 2009) after the kernel update. … Puzzling.
