Okay skuzzy here's something new.
I have Time Warner Roadrunner as my ISP.
I hooked up a second computer (a laptop) to the service via linksys ethernet hub and signed up my other half under her own account.
This has driven vox nuts. If we are both on the squad channel on radio 5, we both get a bad echo anytime any squadmember talks on Vox.
We can't hear each other talk via squad vox.
If we are both in the same area all vox echoes, in seperate areas vox is normal. Other than this, the game plays normal.
I'm betting there's an IP address problem here, huh?
Let me know what you think and what could be a possible solution, the neighbors are pretty bummed about us yelling check 6's up and down the stairs all night:).
