WIFI signal is too weak, so the speed is falling back to a point where you have the limited/no connectiity. An external antenna on your WIFI adapter(if this feature is supported) will help to increase your TX and Rx signals.
I had connected to a wireless network via my lapto.
but, it show Limited or No Connectivity...
and i cant do anything with it....
Anyone knew what it the problem??
We need to know what type of modem you have, who is your ISP.
What OS and Service pack are you using.
Is DHCP client enabled in Services.
Is TCP/IP configured correctly.
Are you getting a 169 IP address with your limited or no connectivity.
Have you tried turning on your modem first, then the PC?
Explain all above points to give us a better description of your setup and your problem.
