I have 5 laptops that have a wireless g adapter.

[CatchPhrase]

I have 6 laptops(family members/roommates) that have crappy signal with the linksys wireless-g router. I live in a stone apartment and was thinking about getting a wireless-n router (linksys wrt300n). Would they all work fine with it and get a better signal?
Wired is out of the question and the existing router is in the center of the building.

When wireless n becomes the new standard will this work fine with everybody (linksys wrt300n)?

Native American use to say that ?Pale Face? has two tongues.

Wireless Vendors do too.

On one page they say that it would, in another page that would say.

The standard is Not out because they are fighting over it. So it is implicit that at the end someone loses.
