I have a Lenovo laptop and ever since I started using the WIFI with EZ-V4 I can connect but it is very slow, like graphs update at 1 second intervals and there is a ton of pauses. I then noticed that under the signal strength list for the WiFis the one for EZ-V4 board it says "LIMITED". I googled it and I see where people say that it is a bug in Windows 8.1. I called Best Buy and they said that it is not the computer that it has to be the board, because they never have seen it be the computer it is always what it is connecting to that cause the "Limited" indication. Does anyone know what this is?
Upgrade to ARC Pro
Experience early access to the latest features and updates. You'll have everything that is needed to unleash your robot's potential.
I would suggest however connecting to your EZ-B and putting it in client mode connected to your router. Having internet access while using ARC has a lot of advantages and may resolve the performance issues you are seeing as well.
I will mark this "Limited" issue, resolved and keep digging into why I have slow performance.
