Help with Digital Aquatics to PC / Need a wireless solution

[gregzz4]

If any of you have ever connected your Reefkeeper to your PC with MyReef, I'm sure you've noticed that the pH reading either spikes or reads ERROR
I've read it's due to the powered USB ports adding juice to the DA system

I've read that it can be fixed by either using a Laptop running on batteries (don't own one), or by using a wireless router and so on

I'm looking for help on how to do this

I have a wireless modem, but I don't want to network my PC to it

Thanks for your input
