Acer Tablet w/Wireless, Linksys G, Help!

Have spent the better part of the last 3 days trying to get both my old desktop and new laptop/tablet to work on a simple home network.

After talks with AOL, Netgear, SMC, Linksys, Road Runner....

1) Finally have the desktop seeing the Linksys Wireless g 4-port router... the router sees the Motorola Cable modem... which sees AOL Broadband. OK there.

2) My new Acer 111 laptop/tablet pc is getting the wireless signal from the router but does not connect to the internet? Linksys says it's a Acer issue.

Any thought or comments would be greatly appreciated.

At the rate I'm going I could have hard wired the whole neighborhood in the amount of time I've worked on this.

Thanks for any advise.
