im working with a dell inspiron laptop computer, just recently my wifi was working great up until yesterday. all of the sudden i couldnt access the internet. i can get my wifi to connect to the network, it says i am sucessfully connected to the network but i cannot access the internet. i reset my wireless router three times (for my built in wireless card) , i did a diagnostic and repair and still it still only connects to the network, but not internet, i also did a system restore to see if that may fix the problem but it didn't. My last option would be to reboot my computer but i would like to fix it without having to reboot, also if i did reboot would i have to reconfigure my wireless card? if anyone has any suggestions or answers it would be helpful thanks.
