Re: Wireless Gateway Device/Feature Comparison

As a warning, be aware the following models use the Intel Puma 6 chipset, which has known issues that can cause severe latency (high ping times) and other weird issues that Intel has been unable to fix with firmware updates: DPC3939, DPC3941T, TG1682G.

Re: Wireless Gateway Device/Feature Comparison

When will the XB6 become a self install where it can be picked up at a service center? Or shipped out? And not just for gigabit?

You might want to read this thread if you have more than one ethernet device (like a PC) that you want to connect:

No I don't.  And I can't use it until this issue is resolved.  I have more ethernet connections than the XB6 can support when I use multiple switches.
