Cisco :: AP1231G-A-K9 Access Points / Very Slow Throughput

I recently setup our small office network using the following setup:

Cablemodem <--> router <--> 1231AP(role root bridge with wireless clients) <-> 1231AP(role non-root bridge with wireless clients)Code on both APs: 12.3(8)JEE.Office network generally has less than 3 wireless clients connected at any one time to either AP. AP's are a mere 50' apart; clients are all less than 30' from either AP; they all show excellent signal and connected at 54mbps signaling rates.
 
All is/has been working very well & very stable with the exception of speed. We have business class service from RR, approx 25mbps dl, 2mbps ul. Any hardwired client to the router switch ports are able to download at speeds averaging 23mbps. Any wireless client connected to either AP is never able to exceed download speeds of 5mbps. With no other wireless clients connected except my one test client, I was not able to exceed 5mbps throughput from either AP that I connected to.
 
I can confirm that the ethernet connection between the router and root bridge is up at 100mbps-FD and not showing any errors: [code]
 
Are these very slow thoughput speeds normal of this hardware combination?I did much searching/googling and found claims that by eliminating TKIP it almost doubles the actual wireless speeds our clients can obtain.
