Network Problem

[hyperhamster]

What I am doing:
1. connecting to WiFi AP
2. trying to access any internet site.

What is strange:
1. Internet Explorer, HTC weather and Stock works perfect
2. BUT Opera, Youtube and QuickGPS does not work
3. Intra-network works perfect either from Opera or IE.

Windows config:
1. I set DNS, WINS and proxy with port
2. in connections profiles I have one "My work network" for both Work and Internet.
3. WiFi session connects to Work profile.
4. NO VPN or Modems in profile ...
5. Adapter connects to Work profile.
6. I have certificates installed to access WiFi net.

What I did to resolve the issue:
- I did MTTY and nothing changed;
- I did change of MTU - did not help;
- I've renamed proxy in settings from Symbolic representation to IP - did not help;
- I've tried both 6.1 and 6.5 WM versions and ROMs
- I've tried many combinations of different settings, but nothing helped.

Some times I saw that the issue disappeared on some ROMs after a number of settings changed during tries... but I did not get a logic of how it become working...

I appreciate any help from you and ready to make a testing...
