Nearly 24 hours and 4 or 5 Linksys Support Techs later I still have no answer.
Here is the puzzle:
Linksys WRT54G2 Wireless router connected to a Westell dual connect modem, provider, Verizon DSL
one desktop, running XP, wired to the Linksys router, has full functionality, what I am using now
one laptop, new HP, running Vista, with wireless adapter
another laptop, old Compaq, running XP, with wireless adapter
I would like the laptops to connect to the internet wirelessly
both laptops can make a connection with the secured network I configured on the router and named 'jetnet'
both can ping 192.168.1.1 (which one tech called 'the router')
neither can ping "www.google.com" or any other web server when connected to 'jetnet'
both the laptops can connect to another of the four ethernet ports on the Linksys and connect to a network connection called 'verizon' which is labelled WAN Miniport (PPPOE), and find webservers
The techs have all had me try manually configuring the network through the 'setup page', with various combinations of channel number and advanced settings and security types. The firmware has been updated, the power cycled off several times. With one tech all security and wirewalls were disabled. Still no go.
After working with me all night, the tech(s) decided it must be the router, a WRT54G v8.2. So I bought a new router this afternoon, the WRT54G2. I have been through their checklists with the new router to, including 'flashing' the firmware and cycling the power off. I have cleared out and readded 'jetnet' to the Vista machine in 'Network and Sharing' upteen times in every conceivable way. I have used different network names.
The problem's beginning is a little hard to place. It was one evening last week, my wife came to the computer in the evening after my son had finished with it, and found she could not get her email server. Thinking it was a virus corrupting the dns I delayed persuing this, thinking I was faced with a Vista reinstall. Last night I discovered that my son was using this other network and so began the quest. Don't know what my son might have done on the computer. He is a light user, does some browsing etc. My daughter is even more difficult to debrief because she just gets a connection however she can and dosen't pay close attention. I have Zonealarm and AVG Free Editions on all computers.
I am not sure where to turn next. Any ideas?
