WIFI in my office through Linksys router WRH54G is not connecting on my Galaxy Note Android ICS. Mac filtering is there but no other security. I have registered the note's Mac address on router. When I am connecting it, it is only showing saved but not connecting and I have tried changing setting from DHCP to Static IP and input the following IP 192.168.1.180 gateway 192.168.1.1 24 network suffix 220.127.116.11 or 172.31.6.5 (as shown in my laptop)DNS 18.104.22.168 or 172.31.6.85 DNS Our DHCP setting is from 192.168.1.2 to 192.168.1.151 Please help me out. It is connecting at my home with Siemens wifi Router with WPA security. Signal strength is excellent at my seat.
