We have a new wireless internet link that was installed today, but now when we push the ISA server to use this link we get the following error:
Error Code 64: Host not available
Background: The gateway or proxy server lost connection to the Web Servr:
Source: ISA2006
We have a backup DSL link and if we push the traffic to the backup link we don’t get this error.All browsing seems to be affected and not just some sites.
Please advise

    seems the problem is from the wireless ISP, use tracert to determine the failure node.

    That sounds right.  Remember that the medium is totally irrelevant.  ISA/TMG is just going to be looking for whatever piece of hardware is on the opposite end of the patch cable, couldn't care less about anything past that.  So the equipment the ISP has placed there to make the transition from wired to wireless has to be functioning and dependable,...the ISA/TMG only needs to see it.  ISA/TMG would not know what "wireless" was if it tripped over it,...unless you tried using a wireless adapter in the ISA/TMG machine which would be a very silly thing to do if the Nic along with its software drivers wasn't designed properly,...and in my opinion be just plain silly no matter what,..but that's just me.
