|One of the servers has a PCI wireless card and connects to another network. |
You've already stated the one network is "setup is one building" so I'm wondering if the 2nd network is in a different building or on the other side of a concrete wall or something like that?
Things like concrete walls can interfere very much with signal strength so I need to know where this 2nd network is in relation to the server connected to it.
if I were to put a 2nd wireless card in server 2 would this help anything? or Server 1 even
Simply put, no. First, let's figure out what's going on before attempting to do anything about it. I can tell you right now though, adding a second wireless NIC to this server isn't going to help.
If you try to stream or play too much media it freezes on you. or if 2 devices on network 2 try to play something it freezes as well sometimes though when the signal is good -55 ish there is no issues.
I've said this before and I'll have to go on saying it until I retire from computing completely or I die.
Wireless is a convenience and as such has certain limitiing factors. It's inherently susceptible to lag and latency. Performance-wise, it can never compare to a wired solution.
What this means to you as the end user is, when you're streaming video, it's likely to be choppy from time to time. The more heavily used the WLAN is, the worse it's going to get for everybody. So, if you're trying to stream video via wireless from said server and several other people are too at the very same time, it's going to suck mightily for everyone.
The whole issue you're having could simply be that you are using wireless and trying to stream video and who knows what all else at the same time.
It matters not how straight the gate,
How charged with punishments the scroll,

I am the captain of my soul.
