I have been using several wireless tablets with AC with speeds almost approaching the desktop computers. Therefore, you should troubleshoot the wireless computers before giving up:
1. Look at what other WiFi networks surround you (Go to Control Panel>Network Connections, click on the "Wireless Network Connection" icon and choose "View wireless networks"). If there are several, you may be competing for the same WiFi channel with a nearby network, reducing bandwidth. I use a tool called CommView for WiFi to display the nearby networks, including what channel they are using (30 day free demo
here) . Use the setup utility for your wireless router to change to an unoccupied channel.
2. Reposition your wireless access point or router closer to the area where the wireless computers are used. Speed deteriorates with increasing distance from the antenna of the router. Placing the router as high up as possible also helps -- on a cabinet instead of a desk.
3. Upgrading from a "G" router to a "N" router will increase the strength of the wireless signal.
4. Wireless home phones (not cellphones) compete for bandwidth with WiFi.
Good luck.
