10.5 Touch Panel Dissected

After further investigation, the default wifi card (30mW) made by Z-com can almost definitely be upgraded safely to a 100mW card yielding higher sensitivity and better performance around a home. I'm not sure what battery life would look like as of yet, and I'm almost positive it will not be great. You'll have to stock the house with power docking cradles to yield happ(ier) results. Disclaimer: I would definitely test this theory before recommending to customers.

For those looking to test out my mod theory, here's the card I'd recommend:

Be careful with buying replacement cards. Obviously you would want one with the same wireless chipset to increase the chances that the current drivers will recognise the card. The one that you pictured above uses the Prism 3 chipset (can tell because it is XI-330). The second link you gave goes to cards that use the Prism 2.5 chipset (can tell because XI-325). Now they should work, but why risk it? Why not track down a 100mW Prism 3 card?

When you're right, Samer, you're right. The chipset *is* prism 3 and i don't know what i didn't catch that. The card that you'd want is the XI-330H (not the XI-325).

Great question, Rob. In my limited experience with hacking linux, you have to build the driver into the kernel (with wpa-supplicant) in order for WPA to be in working shape. Not saying that it's hard, simply that it won't work by physically swapping the card with the model you suggested. This indirectly touches on what Samer was saying... that once you change chipsets around (this one being a Texas Instrument chipset, not Prism 3.0), you have to tell Linux how to support the new hardware chipset you just plugged into it.

Here's a list of the z-com chipsets/drivers for those who are curious:
