Dear, I bought Tp-link router almost a month because I brick my Linksys WRT54G v2. Now I un-brick the Linksys with dd-wrt. Now I want to enhance the router signal, since my home is made of concrete. Two end of a three sitter can be a different. So I plan to use the old Linksys WRT54G to make a WDS. All I want is: 1. WDS (one SSID, one subnet because my brother may take his turned-on-notebook moving from bedroom to living room.) 2. wireless security WPA/WPA2 + TKIP/AES, etc. (WEP is not consider) I did try dd-wrt, but it's WDS only support WEP. I did try tomato, it works. But it make the network unstable. No one can connect after 17:30. I think it might be caused by neighbors back home. After a while, I need to reset both routers. Could someone told me which firmware is best for Linksys WRT54G v2 and fulfill my 2 requests, please. Thank you very much!! Best Regards, Antony
