IP address problem

[laurenceparsons]

Hello All,
Yesterday I upgraded a Dell laptop with more RAM, from 384Mb to 2Gb, and that worked fine; the PC sees the new RAM. However, now it will not connect to the Internet. We have a Qwest 2Wire DSL modem with wireless, and it normally issues an address of 192.168.0.66 to this laptop. Now DHCP gives it 192.168.16.xxx which of course is a different subnet.

If I change the Dell wireless adapter to use a static IP (the original address) it connects fine. This laptop user does not have an ethernet cabled connection available in his office, so its wireless or nothing. He also has Verizon vzaccess software loaded which he uses to connect to the Internet while traveling, which he does almost every week.

I'm stumped. I don't know why his laptop should suddenly be getting a different IP address now. He doesn't have the knowledge to manually change his IP settings every time he's in a new location. Any ideas would be appreciated, thanks.

Does the modem have sync?

Hello zacke

I'm not sure what you mean by does the modem have sync?

On the 2Wire, what lights are currently on?

Hi zacke,

I'm not at the office at the moment, but the DSL light is solid and the Internet is working for the cabled PCs. The wireless light is flashing when there's wireless activity, which Qwest says is correct. I had to set the laptops to static IPs and then they can get on fine. However, when I use DHCP they are being given an address in the range 192.168.16.xxx instead of 192.168.0.xxx. Don't know if that helps you? Could the other IP addresses be coming from a different wireless point?
Thanks!
