I have a 857W router with IOS Image Name: -advsecurityk9-mz.124-11.T2.bin and IOS version: 12.4(11)T2 and am using SDM Express Ver 2.4. This particular router only provides me with a combination of WEP 40/128 bit encription with/without TKIP. I want to know if I can get WPA if I upgrade my IOS or SDM. Please help…
