Try reconnecting the internet from the source of Wi-Fi.. I how it helps you..
do you mean to say by switching off the router, and then turning it on again? i did that, to no avail.
probably the issue is due to conflicting IPs? my phone's been assigned the IP address as 192.168.1.2. may be this is conflicting with my PC's address (though its IPv4 address is 192.168.1.195). i checked the DHCP pool summary on my router page, and indeed it tells that 192.168.1.2 is assigned to android. any idea about this?
EDIT/UPDATE: Hurrah! issue rectified!
will explain how and what was done, but after i lift some iron. had to postpone that, chasing a solution to this issue.
Step(s) taken: since the PC and the cellphone were both being alloted dynamic IP adresses by the router, most probably this was creating conflict in wifi connection for the phone. after some trials, i finally switched off DHCP in the router, and assigned a random static IP to the phone, and all's set now!
