Cannot connect to Wimax ISP with Vista Ultimate x64

[Guest]

Hello,

I can't connect to a Wimax ISP with Vista.

I get : cannot communicate with primary DNS Server(xxx.xx.xxx.x) when I try
to diagnose this problem with Windows Network Diagnostics.

I am using Vista Ultimate x64.

I created a virtual PC Windows XP on this Vista machine and everything works
fine with XP.

So I know it's a Vista problem, not hardware, not drivers.

It's something new with how Vista communicates with the wireless AP that is
different than Windows XP.

Got any good ideas how to fix this Vista?

Thanks,
Mac

It sounds like your wireless access point isn't compatible with Vista.

MS Internet Connectivity Evalution Tool

The Internet Connectivity Evaluation Tool checks your Internet router to
see if it supports certain technologies. You can use this tool on a PC
running either the Windows Vista or Windows XP operating system. If
you're planning to run Windows Vista, this tool can verify whether your
existing Internet router supports advanced features, such as improved
download speeds and face-to-face collaboration using Windows Meeting Space.

The tool is intended to be run from a home network behind a home
Internet (NAT) router. Running this tool from behind a corporate
firewall or on operating systems other than those specified above won't
produce accurate results. This tool requires administrator privileges to
run. The tests can require up to 10 minutes to complete and do not make
any permanent changes to your router. For the most accurate results,
your computer should be connected directly to your Internet router,
using a wired connection.

Hi Malke,

Thanks for the reply.

It turns out the wireless ISP had a certificate on the logon site that
didn't have a trusted root. So Vista instead of giving me an option just
refused the connection.

I called the ISP and a support guy gave me an alternate URL that had a
trusted cert and I can logon through that page.

I'm glad you got it sorted. Thanks very much for taking the time to post
the solution.
