Need help VISTA/XP ping

OK...I have said this soooo many times in real life. I hate wireless with a passion.

I have researched/google the internet to find this solution and cant get my problem fixed.

Vista will not allow XP to ping the machine. I have done everything that you can do to fix the problem. I have turned my firewalls off (mcafee/windows). I have downloaded LLTD to the XP machine. I have gone and turned on echo requests and whatever other functions I could find on my XP and Vista.

I come to this forum hoping somebody has had this problem in the past and found a fix.

Get this....I dont have the problem when I am on VPN connection where I can use my router with ethernet cables. Its only with wireless. It seems that Denver, CO is so friggin cheap they can only provide wireless in most of their motel rooms. Even the high dollar motels only have wireless available. GEEZUS if I was a critic I would post how horrible service is in the Denver area.

Anyways, I cant get around the wireless issue if I want to use keyclone.

So, are there any people out there who know of this problem? Basically, VISTA will recognize the XP machine and see all of the WOW games that are up on both machines. But the XP machine will only see the ones it has up and running and not the VISTA machine. Whats wierd too is sometimes the MUTE feature on the XP machine will work on the VISTA machine BUT NOT the VISTA mute to the XP machine. lol...geezus its a mess.

I know its not keyclone now that I did all of this research. its this friggin VISTA crap.
