Can connect to router but no internet connection

kenman2626 · 12-04-2007, 10:41 AM

Basically my laptop wireless (after a year of being fine) suddenly can not load google etc. It says I am connected to my router with excellent signal yet I still cannot connect.

Have tried...

multiple/auto ip's/DNS etc
Unplugging the router
Fully reinstalling my laptop!
Turning off encryption in router settings

Nothing works. Anyone?

What happens when you bypass the router and connect directly to the modem? ( Be sure to power cycle the modem when you do this )

Not tried, do not have a cable for this.

Well . . that would be the first troubleshooting task

TCP/IP stack repair options for use with Windows XP with SP2.

Start, Run, CMD to open a command prompt:

Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reboot the machine.

Ok, borrowed some cable last night and connected from router to laptop. Still didn't work.

Will try the cmd thing tonight. I have done the 2nd line before but not the first.

Try connecting directly to the modem . . . that will tell you if the Router is bad or not.
