So I finally added the last 2 GPUs to my mining rig.  Before, I had 4 cards hooked up and everything hashed as expected, but with some "mildly" frequent disconnects from pools (especially suprnova), according to the software.

Last night I added the last 2 390x's, and everything booted and all cards were recognized just fine.  However, once I start the miner, TeamViewer would almost immediately disconnect and I would have a very hard time reconnecting.  The miner reported eth hashrate as expected (~160 mh), but my pool (coinotron) reports only 2-5 mh, which is a fraction of what it should be.  I tried running Genoi's latest release, but the CPU usage jumped to 99% once the mining started, and after a couple minutes I saw TeamViewer disconnecting as well as display driver crashes, so quickly scrapped that strategy.

I'm not really sure what might be the issue, but it seems maybe the wireless adapter I have installed isn't doing what it needs to.  Any advice as to what might be the issue?  For completeness sake:

4gb RAM
Celeron CPU
2x 1k watt PSU
4x 390x
2x 280x
Windows 10

Thanks!
